More often, allergic reactions manifest themselves in the form of skin rashes, as well as problems with the digestive and respiratory systems. There are also several uncharacteristic symptoms that become the body’s response to events. inflammatory processes. One of them is considered to be an increase in body temperature due to allergies. In such a situation, it is important to promptly determine the cause of the problem and take appropriate measures.
Can there be a fever due to allergies?
People often perceive the appearance of allergy symptoms such as a runny nose and nasal congestion as the first signs of a cold. The addition of uncharacteristic symptoms complicates diagnosis. Only a specialist will be able to determine whether an increase in body temperature may be due to allergies in your particular case.
When foreign substances enter the human body, an active release of histamine begins. This substance is involved in metabolic processes and is also responsible for the normal functioning respiratory system and organs of gastric secretion. Under the influence of an allergen, the concentration of histamine in the blood increases many times, which leads to negative consequences for good health. There is an increase blood pressure, excessive activity of the lacrimal glands, increased volume of gastric juice, problems in the urinary system.
Against the background of all the changes in the body occurs a sharp decline immunity. This allows the infection to penetrate the human body more easily, and inflammatory processes develop. They are the ones that cause an increase in body temperature.
With allergies there is no strong fever. The increase in temperature is often insignificant, and therefore does not require separate treatment.
How to distinguish it from other diseases?
Signs of allergies, combined with an increase in body temperature, can easily be confused with the manifestation of other diseases:
- Flu and ARVI. When viruses enter the body, signs of severe intoxication of the body appear: headache, dyspeptic disorders, muscle discomfort, drowsiness. With ARVI or influenza, there is no itchy skin or rashes on the epidermis.
- Rubella. This problem is accompanied by the appearance of a characteristic rash on the face and body. The temperature rises significantly. Sometimes it can be difficult to bring it down even with strong antipyretic drugs. With the right approach to therapy, symptoms subside on the second day. The temperature with allergies is not high.
- Sinusitis. Accompanied by the discharge of a large amount of secretion from the nose and painful headaches. Hyperthermia will persist until a full course of treatment has been completed.
- Chicken pox. It is characterized by the spread of the rash throughout the body. It has the form of watery spots. After three days, the blisters subside. With allergies, the rash lasts quite a long time.
- Scabies. The rashes are very similar to allergic ones, but unlike them, they itch very much at night. The disease is contagious and can easily be transmitted to all family members.
An incorrect diagnosis leads to incorrect treatment and the development of serious complications. Therefore, when the first negative symptoms appear, it is necessary to seek help from qualified doctors.
Causes of fever due to allergies
The causes of fever due to allergies lie in inflammatory processes that develop against the background of the spread of infection. The following factors can provoke this problem:
- Long-term use medications.
- Blood transfusion. Donor blood is perceived by the immune system as a foreign substance, resulting in an inflammatory process.
- Hay fever.
- Food allergies.
- Serum sickness is a reaction to protein drugs entering the human body.
- Contract with animals or plants. Due to an allergy to wool, the body temperature rises to 37 degrees.
- Insect bites.
If such factors are present, the patient is first prescribed antihistamines. If this does not bring the desired result, it is required additional examination and another therapy program.
Increased temperature in various allergic diseases
If a patient suffering from allergies experiences an increase in body temperature, this is a reason to seek advice from an allergist. Such a symptom may indicate the development of complications of the disease and the addition dangerous infections. Only an experienced physician can accurately diagnose.
Temperature with allergies becomes one of the symptoms of several types of disease.
Allergic dermatitis
With dermatitis of an allergic nature, an increase in temperature is extremely rare. Such a symptom can only appear in an advanced stage of the disease, when an infection has entered the body through wounds formed on the skin. In this case, the affected area must be quite extensive.
Dermatitis, caused by exposure to low-quality cosmetics, often has serious consequences. Therefore, it is important to test for the presence of negative reaction body. This is especially true for sunscreens. With a combination of allergies and sunburn the temperature may rise to 38 degrees.
If your body temperature begins to rise due to dermatitis, you should immediately consult a doctor. There is a high probability of developing a generalized infection.
Food allergies
The impact of food on the human body is recognized as one of the most gentle. Hyperthermia under the influence of such allergens appears only in exceptional cases. Other symptoms should also appear:
- Severe attacks of nausea, alternating with vomiting.
- Diarrhea.
- Excruciating pain in the abdominal area.
- Headache.
- Dizziness.
In such a situation, the body temperature will reach 37.5 degrees. The patient must be given first aid as soon as possible. Otherwise, severe dehydration will occur, which threatens not only health, but also human life.
Allergic rhinitis
Rhinitis is becoming one of the most common forms of allergic reaction. The release of histamine that occurs after contact with an allergen becomes destructive to the nasal mucosa. Severe swelling develops, secretions begin to separate in large quantities, tormenting severe itching.
This disease in adults can be accompanied by an increase in temperature up to 37 degrees. If to general symptoms signs of conjunctivitis appear, you should immediately consult a doctor.
Allergic rhinitis is more often diagnosed in the spring, when the flowers bloom. a large number of potentially dangerous plants. The problem can also be caused by dust, mold, animal dander and other allergens.
Reaction to insect bites
Fever in allergies caused by insect bites is a relatively common phenomenon. The immune system reacts violently to toxic substances entering the body. The most dangerous are the bites of hornets, bees, gadflies, and wasps. In the presence of allergies, vascular permeability is high, so the poison is quickly absorbed into the blood and spread throughout the body.
Allergies reduce a person’s protective functions. The body does not have enough strength to resist the toxic effects of insect venom. In this regard, the risk of complications increases many times over. The disease is accompanied by an increase in body temperature up to 38 degrees, severe itching and swelling of the tissues at the site of the bite, headache, and a general deterioration in health. Therapy in this situation is carried out with the help of antihistamines.
Allergy to animals
The cause of the negative reaction of the body is not only wool, but also saliva, particles of skin and animal feces. Therefore, allergies often develop even in those who come into contact exclusively with hairless cats and dogs.
This type of allergy primarily affects the functioning of the respiratory system. Choking appears and torments coughing, pressure is felt in the chest. Can also be found skin manifestations, as well as signs of conjunctivitis. Hyperthermia is insignificant and in many cases goes unnoticed.
Allergic cough and bronchitis
A mild form of the disease is considered to be a cough of allergic origin. It is accompanied by tickling in the throat, soreness, and hoarseness of the voice. When infectious diseases occur, body temperature rises, which indicates the development of an inflammatory process. It affects the bronchi. Bronchitis develops.
More often, allergies manifest themselves in the form of bronchitis. The problem is accompanied by a dry, debilitating cough and difficulty breathing. Exposure to an allergen leads to dilation of the vessels of the respiratory system, which increases their permeability. This provokes a strong narrowing of the bronchi and increased negative symptoms. In such a situation, body temperature can increase to 38 degrees.
Allergy to medications
An allergy that appears after taking pills is considered the most dangerous form diseases. It is difficult to treat and develops complications. For its treatment, strong antihistamines in large dosages.
If you are allergic to medications, your temperature can rise to 39 degrees. At the same time, hives, tissue swelling, and severe itching appear. General health worsens, headaches and drowsiness appear.
Allergy to pollen
This disease is called hay fever. It is accompanied by nasal congestion, redness of the eyes, swelling and itching of the eyelids, and bouts of sneezing. No feverish state is observed. If the disease occurs in mild form, then hyperthermia does not occur.
When an allergy to a mixture of pollen from various plants occurs, the disease can develop into severe form. When an infection occurs, the temperature increase can be significant. At the same time, dizziness, weakness, loss of appetite appear, and problems with sleep arise. This condition is often diagnosed in allergy sufferers during the period of active flowering of plants.
Hives
Urticaria is an allergic reaction characterized by red or pink blisters on the body. The affected tissues swell, and unbearable itching appears. Symptoms develop suddenly. The rashes are most often localized on the face, arms or legs. In severe cases, they can cover the entire torso.
With a favorable course of the disease, the blisters quickly disappear and do not leave behind scars. Temperature with urticaria appears in rare cases. Its maximum is 39 degrees.
Increased body temperature in children with allergies
The immune system child's body not yet fully formed. She doesn't handle negativity well. external factors. Therefore, allergies in children often occur in a more complex form than in adults.
Fever in a child with allergies is often the very first symptom of the problem. It does not rise above 38 degrees. After a couple of days, it is joined by skin manifestations, signs of conjunctivitis, rhinitis, and so on. Most often, this reaction occurs in children to vaccinations and the use of medications.
The child has elevated temperature in case of allergies, it can become the only symptom. This is possible with low activity immune system And acute course diseases. A diagnosis can be made after collecting a complete history. The doctor finds out whether the baby has had contact with possible allergens, whether the little patient is at risk, and so on. Trying to cure a child in such a situation on your own is strictly prohibited, as this can lead to irreparable consequences for his health.
Reducing temperature in case of allergies
In exceptional cases, a decrease in body temperature is observed with allergies in adults. Active release of histamine can provoke an increase in nitric oxide concentrations and hyperpolarization cell membranes. As a result, muscle fibers vascular walls relax. The clearance increases. The result is a decrease in blood pressure and body temperature. If this symptom is accompanied by shortness of breath, rapid heartbeat, wheezing in the lungs, the appearance of cold sweat and paleness skin, this may indicate the development of anaphylactic shock. In such a situation, the victim requires emergency health care.
In children low temperature In case of allergies, it can become a sign of serum sickness. You can prevent its occurrence if you give your baby a dose of an antihistamine a couple of days before vaccination. But before that, you need to consult your doctor.
In infants, a decrease in temperature may indicate the development of a food allergy. At the same time, characteristic rashes appear on the skin, the affected areas peel off, and severe itching appears.
Changes in body temperature often do not require therapy. It is important to focus all your efforts on fighting allergies. When the underlying disease is defeated, the symptoms will disappear on their own.
An allergy is an inadequate response of the immune system to an irritant. Currently, it is diagnosed in 80% of the world's population. Allergies are classified into various shapes depending on the type of allergen, which have their own clinical symptoms. For example, some people have a fever due to allergies.
If a person is sick, an increase in temperature is perceived as a sign of inflammatory changes. With an allergic reaction, the fever is so unexpected that the question involuntarily arises: does fever occur with allergies, and why does this happen?
It should be noted that this symptom appears infrequently, and it most often indicates the presence of an inflammatory process of third-party origin.
Causes
Temperature with allergies in adults and children can be triggered by the factors given in the table:
| Factors | Associated symptoms |
|---|---|
| Food allergens | It is possible that with food allergies, body temperature can rise to 39 degrees. Acute manifestations of food intolerance can provoke increased sweating, skin irritations, rash, fever. |
| Medications | It occurs with irritation of the mucous membranes, itching, signs of intoxication and fever up to 39 degrees. |
| Vaccination | A routine vaccination can cause a rash, swelling and hyperemia at the injection site, as well as fever of 38 degrees and above. This condition is a medical emergency. |
| Animal fur | The temperature for allergies in a child and an adult in this situation varies around 37 degrees. Taking antiallergic drugs eliminates signs of allergy, including low-grade fever. |
| Pollen, ragweed | If a person suffers from intolerance to pollination and flowering of plants, sometimes his temperature may rise against the background of other manifestations of allergies: rhinorrhea, conjunctivitis, etc. |
| Insect bites | The temperature usually increases at the site of the bite, which also hurts and swells. |
How to determine that the cause of a rise in temperature is an allergy?
The temperature with allergies in children and adults is practically no different from the febrile state with colds. But the treatment of these conditions cannot be the same, and, moreover, if it is incorrect, it will certainly affect the person’s well-being. That's why the real reason temperature rise must be determined accurately.
| Disease | Characteristic signs |
|---|---|
| Allergy | If we are really talking about an allergic condition, then, in addition to the fact that fever may occur with allergies, there are other accompanying symptoms of this condition. Interaction with an allergen ends with a clinical picture known to every allergy sufferer: itchy skin, sneezing, red rashes on the skin, allergic runny nose and much more. |
| ARVI and FLU | With respiratory tract infections of viral or bacterial origin, fever is always accompanied by a sore throat, signs of intoxication, headache, that is, symptoms that have nothing to do with allergies. |
It should be noted that an allergic reaction develops quite quickly - its signs can appear within a couple of minutes after contact with the allergen. In turn, a cold begins gradually, it is characterized by staged development, and, on average, lasts at least 7 days.
An elevated temperature during an allergy, which increases in a short time, means a pronounced reaction of the immune system to an irritating aspect. This condition can be dangerous due to the development of anaphylactic shock, etc. If, due to allergy symptoms, swelling of the face and shortness of breath develop, developing into suffocation, general deterioration well-being, necessary urgent Care doctor
Features of temperature in allergies in children
A child's immune system is not as perfect as an adult's. Therefore, to be able to withstand external pathogenic factors, in particular, to allergic irritants, it is much more difficult for her. For this reason, allergic reactions occur more often and more severely.
An allergy with a fever is more dangerous for a child, as it can lead to serious complications. Therefore, when sudden appearance fever after vaccination, insect bite or medication, you should not hesitate to seek medical help.
Sometimes the temperature of allergies in children rises due to its consequences. For example, delicate skin at this age is more difficult to recover from traumatic factors. If allergy symptoms go away slowly, the itching continues long time(most often due to inadequate drug treatment or its complete absence), then at the site of the rash, foci of inflammation form, which become secondarily infected and are complicated by the appearance of purulent contents. If there are a lot of such rashes, the body temperature rises, but this will not happen because of the allergy itself, but as a result of the inflammation that arises against its background.
What should first aid be?
Whether an allergy can cause fever is an extraordinary question only until the allergy sufferer himself encounters this condition. If appropriate measures are not taken, the temperature may continue to rise, which will negatively affect your well-being. To correct this situation, you should use the following tips to reduce fever.
- Eliminate or minimize contact with the irritating factor.
- Take an antihistamine that was previously prescribed by your doctor. If no drug treatment has been carried out before, you can take Suprastin, Zyrtec or Loratadine in the dosage recommended for age. Most often, the effect of an antihistamine completely eliminates not only clinical manifestations pathology, but also the temperature that accompanies it.
- If an insect bite has been recorded and an allergic reaction has developed almost immediately, it is necessary to rinse the bite site with plenty of running water as soon as possible and treat it with any antiallergic ointment. This will help relieve the local inflammatory process.
- To improve your overall well-being, you can take enterosorbents ( Activated carbon, Enterosgel, etc.), which help remove toxins from the body. Also, for this purpose, it is advisable to drink clean, still water in sufficient quantities.
- If there is a suspicion that the allergy is caused by a drug, it is necessary to stop using it at least for the next period of time. It is recommended to consult your doctor, who will select an analogue of this drug and rule out additional causes that can cause an increase in temperature in the future.
Treatment
The answer to the question - can there be a temperature with allergies and what should be the treatment - should be known to all allergy sufferers. If an adult or child has a fever and all signs of an allergy are present, first of all, you need to consult a specialist. The main thing is to consult with him in a timely manner, since a further increase in temperature values is possible, and then complications cannot be avoided.
If the temperature remains within the subfebrile range or slightly exceeds 37 degrees, there is no need to take an antipyretic drug. If its values have exceeded 38 degrees and continue to rise, you can give a drug to relieve fever before the doctor arrives. This could be Paracetamol, Nurofen, etc.
To combat allergies themselves, experts prescribe antihistamines. Their effect is to suppress biologically active substance, which provokes the symptoms of pathology. Allergy medications come in three generations. This case requires taking first-generation medications, since they are stronger and give a quick effect. Their list includes Fenkarol, Suprastin, etc.
If the skin begins to rash, preference is given to treating the rash in adults. hormonal ointments(for example, Hydrocortisone, etc.). IN childhood it is advisable to use non-hormonal agents, for example, Panthenol, Bepanten, etc.
Prevention
To prevent the development of allergies with symptoms of elevated body temperature, it is necessary to avoid contact with objects or refuse to eat foods that provoke a deterioration in general well-being and cause an inadequate response from the immune system. This is the primary and the most important method prevention of any allergic disease.
After it, you can pay attention to a healthy lifestyle, a balanced diet, strengthening the immune system, hardening and good sleep.
Fever due to allergies occurs more often in children, and it is associated with an excess of irritating factors in the body. The immune system tries to neutralize their pathogenic influence and releases a colossal amount of histamine, so already 10 minutes after interacting with allergens, the process caused appears in all its colors.
On the list the most dangerous symptoms, which can exist for a given pathological process, is a fever with a thermometer reading of 39°. This condition provokes an ambiguous reaction from many organs and systems of the body, so any complications against this background cannot be ruled out. What to do? Before you start sounding the alarm, it is strongly recommended to take antihistamines and antipyretics. If there are no signs of improvement, the help of a doctor is necessary.
Many people are interested in the question: is there a fever with allergies? In this article we will help you answer your question. If the thermometer shows high values mercury column, which means that inflammatory processes occur in the body. This process produces special protective antibodies that fight infection. Can intolerance to food or components of air and water be accompanied by high body heating, and is this manifestation associated specifically with allergies?
Allergies with temperature manifest themselves in many ways. It is caused by the action of various allergens and can manifest itself in various symptoms. Fever is not the most common of these, but it is quite possible. Can there be a fever due to allergies? Heating of the body from the inside occurs during the production of protective antibodies by human organs. 
Temperature is a kind of protective reaction to the penetration of foreign bacteria or substances that accompany the development of pathological environments. This symptom is caused by exposure to an allergen. The temperature may increase with allergies:
- On food products;
- medical preparations;
- plant particles;
- animal saliva and lint;
- insect bites;
- rejection of foreign protein, vaccine.
What to do if your temperature rises
The low temperature associated with allergies in adults goes to zero when the effect of the allergen in the body or in the external environment ceases, and the allergic symptoms stop. Most likely, you will not need a fever reducer. To speed up this process, you should take an antihistamine for allergies. If, however, the body is very sensitive (usually this is typical for children), and the condition does not improve, the patient should be given a drug to lower the temperature.
Usually it is enough to give the patient more drink in the form of tea, compote, fruit juice to reduce a slight increase. The only caveat is that if symptoms of food allergies are observed, then berry drinks should be excluded so as not to increase the amount of allergen. If a child or a weakened person is sick, you should consult a doctor before giving him any medications to reduce his temperature or relieve an allergic reaction. Temperature in children with allergies is observed more often. And this is due to the immature immunity of the little person. Allergy is a dangerous and unpredictable disease that is not easy to identify. Therefore, self-medication can worsen the patient’s situation and lead to serious consequences.It is possible that a negative reaction occurs after taking medications. Internal allergic swelling of the larynx can cause suffocation. If a rapid allergic reaction causes a sharp headache, difficulty breathing, rapid pulse, accompanied by shortness of breath, you must immediately call a medical emergency room, informing the dispatcher by phone about the patient’s condition.
In what cases is fever possible due to allergies?
Even doctors are not unanimous in their opinion whether an allergy can cause a fever, whether an elevated temperature appears due to an allergy, or whether it is a manifestation of other viral diseases against the background of a weakened immune system under the influence of an allergen. Intolerance of the body to manifestations of the external environment or food is very common nowadays.
The reason for this may be polluted air, tap water purified with chlorine and chemicals, industrial emissions, and so on. Food allergies are associated with modern man consumes processed foods that are prepared using artificial flavoring additives. Live fresh fruits and vegetables, meat and milk are a rarity on the table of a modern city dweller. Food products are so processed with chemicals that they can be stored for years; fruits do not spoil if they are kept warm for months. All preservatives, dyes, and flavor enhancers are food allergens. This type of “poisoning” especially affects children. They consume fast food and sweets, which are replete with the listed harmful ingredients. If the reaction is accompanied by an increase in temperature, doctors talk about an atypical allergy. In case of defeat respiratory tract with an allergen, such a symptom is absent. If, nevertheless, it is observed, the cause must be sought in inflammation of a different nature, and the type of causative agent of the infection must be determined. The child or need to be shown to the pediatrician. He will prescribe additional consultations and examinations with other specialists - an infectious disease specialist or an allergist.
Possible complications
How does the inflammatory response manifest? various types allergies:Medicines
If the temperature of allergies in children is caused by medications, then it accompanies inflammation of the skin, mucous membranes, itching and tingling, signs of intoxication and poisoning. You should contact a phthisiatrician or infectious disease specialist if the thermometer shows 37.1 - 37.5 for several weeks. Swollen The lymph nodes Parents should also be alerted. These signs may indicate the development of tuberculosis or another infection, the causative agent of which can be determined in the laboratory and by examination by a specialist. Similar manifestations can be observed against the background of allergies in adult patients. They are complemented by increased sweating. Intolerance to plant pollen, animal hair and other irritants in the air is accompanied by rhinitis, dermatitis and fever. After taking anti-allergy medications, these symptoms disappear.
Insect bites
Some insects inject their poison or substances that cause inflammation during a bite. These include mosquitoes, midges, wasps, bees, ticks, and bedbugs. If a person has an intolerance to honey, then when a bee stings, the bite site becomes very swollen, the temperature rises, and fever is possible. In severe cases, swelling of the airways may occur. This is very dangerous condition. The bites of wasps and bumblebees also cause a strong reaction. Severe cases of intoxication require hospitalization of the child under medical supervision. An inflammatory reaction can occur when someone else's blood is transfused without a preliminary test. Food allergies are accompanied by symptoms food poisoning– cutting pain in the intestines, diarrhea and vomiting. With such a violent reaction, the temperature inevitably rises to critical levels of 38 - 39C. The man becomes covered in sweat. This is called "allergic toxemia." If a patient has an intolerance to a certain product, then with the cessation of exposure to the allergen, all symptoms disappear without a trace. In addition to the reaction from the gastrointestinal tract, a rash appears on the skin. Active food allergens include citrus fruits, red berries and vegetables, spices, sweets, smoked foods, and marinades. If you have any severe fever, you should call ambulance. Doctors will determine the cause of the inflammation and help bring down the temperature.
Allergy prevention
To prevent inflammatory processes associated with allergic reaction, you should try to avoid contact with the allergen. It is important, especially in spring, to prevent pollen exposure flowering plants. To do this you need:- keep windows closed;
- cool the air in the room with air conditioning;
- prevent pollen from getting on pets’ fur during walks, on clothes and shoes;
- stay away from trees and flowers;
- It is easy to prevent food allergies if you know exactly what allergen is causing it and do not include it in your diet.
- To be able to protect the child from this disease, a pregnant woman must follow a healthy and nutritious diet and refuse bad habits, visit more fresh air.
An elevated body temperature always indicates that an inflammatory process is occurring in the body, even if it is quite minor. High temperature indicates active process the body's fight against infection. Can there be a fever due to allergies? Doctors do not have a consensus on this question. Usually allergies are not accompanied by such a symptom, but a fever is caused by a common cold or the onset of a viral disease.
If a person has a fever, he usually does not associate such a symptom directly with an allergy. According to scientists, it develops when collision of the immune system with an allergen. The most common causes of an allergic reaction are:
- certain foods;
- animal hair;
- medications;
- seasonal flowering of plants;
- mold.
They cause severe irritation of the mucous membrane on the face. When a person comes into contact with a substance, causing allergies, then he immediately develops itching, runny nose, and nasal congestion. Then he begins to sneeze and watery eyes appear. Due to the release of histamine, tissue swelling increases and the airways become inflamed, causing coughing.
This condition leads to headaches, as the head pressure increases. The nose may become inflamed and filled with mucus, creating comfortable conditions for viruses and bacteria to multiply, resulting in an infection caused by allergies. When the condition begins to worsen, a low-grade fever (37-37.5 degrees) occurs, and thick mucus is released from the nose.
Thus, fever due to allergies occurs in adults and children, but it is not caused by an allergic reaction, but by a secondary disease that was provoked by the allergy. For example, with allergies in the nose begins to develop chronic sinusitis, which can cause an increase in temperature to fight the virus.
In what cases does an allergy cause fever?
Since in Lately Allergic reactions have become very common and are accompanied by fever; doctors call this reaction an atypical allergy.
Can allergies cause fever? With a respiratory tract allergy, it does not rise, and if this happens, it means that inflammation is developing in the body in parallel, the cause of which must be determined as quickly as possible. In this case, you need to contact a therapist or pediatrician, infectious disease specialist, or allergist.
If the allergic reaction was caused medicines, it is usually accompanied by symptoms such as itching of mucous membranes and skin, rash, severe intoxication, fever.
If you have a low-grade fever for a long time, which is accompanied by allergic manifestations, then you need to contact an infectious disease specialist or phthisiatrician. This condition may indicate tuberculosis intoxication or other infectious diseases that can only be determined by a specialist.
Sometimes an allergic reaction to plant pollen or animal fur may be accompanied by lacrimation and low-grade fever. If the temperature returns to normal when taking antihistamines, this means an atypical allergic reaction.
In what other cases can an allergic reaction in adults cause fever? This condition occurs for bites of various insects. This can lead to a very violent reaction:
It can give temperature food allergy. In addition, it is accompanied by vomiting, diarrhea, intestinal colic, abdominal pain, itching, urticaria, headache, chills, followed by profuse sweating. In this case, you need to urgently call a doctor.
Temperature due to allergies in a child
Allergic reactions in children are more pronounced and stronger than in adults. This is due to the fact that he has the immune system is not yet strong. This is also due to heredity and the fact that the mother did not breastfeed the child and used alcohol during pregnancy. junk food. In addition, a strong increase in temperature is much more dangerous for a baby than for an adult.
A child's allergy temperature may rise after severe signs of an allergic reaction. For example, he had a skin rash for a long time, after which oozing foci of inflammation appeared. If there are a lot of them, then the temperature rises, but this is a consequence of inflammation, not allergies. It requires quick fix allergic symptoms in a child. In this case, you should not give any medicines from fever and from infection.
Doctors do not advise lowering the temperature if it is below 38 degrees. But this is only relevant for colds. If an adult or child exhibits allergy symptoms and develops a fever, you should visit a doctor urgently.
Allergies need to be treated if the cause of its development has been determined. First, the allergen that caused this condition is determined. Your doctor may prescribe antibiotics to relieve bacterial infection or virus, and antihistamines to relieve symptoms of an allergic reaction. It is also recommended to take decongestant medications to clear the airways, helping to reduce inflammation in the sinus cavity and swelling in the nose.
If the fever lasts for a very long time and is accompanied by weakness throughout the body, then you need to take antipyretics based on ibuprofen, paracetamol and analgin. Painkillers help relieve muscle pain and headaches in the heat.
If an allergic reaction in an adult and a child was provoked by medications, then it is quite dangerous to lower the temperature with medications. You should not take hot baths or do rubbing; this is only effective for colds.
Thus, if the question arises whether allergies can give rise to fever or not, then we can unequivocally answer that it appears as the body’s reaction to an infection caused by an allergic reaction. Treatment in this case should be special.
Attention, TODAY only!
Is there always a temperature with allergies in adults? What does it indicate? Expert opinion regarding this symptom.
Clinical picture
Many specialists and patients often face the problem of high temperature when a foreign allergen enters the body.
This symptom is not obligatory and becomes another cause for concern among doctors.
Is it really the temperature, or could it be something else?
Why does the body react to the allergen in this way?
How dangerous is this to human health?
What happens in the body
When a foreign body appears in the body, nerve impulses begin to be transmitted using special substances - mediators.
One of them is histamine, which takes an active part in metabolic processes and is responsible for the reaction of gastric secretion and bronchi.
An allergen can cause disruption of this mediator, resulting in various problems in the functioning of all internal organs.
There are disruptions in the pulsation of blood pressure, lacrimation increases, and excessive amounts of gastric juice, while the “emission” of urine decreases.
An increase in temperature is not a symptom of an allergic reaction.
And if it is observed, then the cause of everything is the inflammatory processes that occur in the body under the influence of viral injection.
In what forms of the disease can it rise?
Recently there have been more frequent allergic manifestations on various objects, products and other factors of human life.
If there is an allergen in the body, then fever is not considered a sign.
It indicates the occurrence of concomitant inflammatory processes that negatively affect the functionality of all organs and systems of the patient.
In what cases can the temperature rise due to allergies in adults?
- if a reaction to medications occurs. The clinical picture is very clear: intoxication of the body, itching of the mucous membranes, swelling of the face and limbs, rashes on the skin, a sharp increase in temperature.
- for tuberculosis intoxication and other infectious diseases. A temperature of about 37.5 degrees can persist for a long time, indicating the presence of serious disorders in the body. In addition to “burning” of the body, the disease may be accompanied by excessive sweating, dry cough, general weakness, and disturbances in the digestive tract.
- for hay fever, allergies to pollen, animal hair. If taking antihistamines brings the temperature back to normal, then this is a manifestation of an allergic reaction.
- Insect bites can cause a sharp increase in body temperature. All this indicates a violent reaction of the body to such an allergen. The clinical picture is varied: surges in blood pressure, swelling of the respiratory tract, pain in the bite area, body temperature up to 30 degrees.
- An allergy can also cause fever to a food pathogen. In an acute process, not only high fever occurs, but also skin itching, aching headache, chills, profuse sweating. The patient's condition requires medical intervention; with such symptoms, you should immediately call an ambulance.
- when a foreign protein or vaccine is introduced into the body. This reaction is called serum sickness and is accompanied by a temperature of up to 38 degrees. The anaphylactic stage can be fatal.
What indicators does it rise to?
When the temperature rises as a reaction to any allergen, the indicators may be different.
From 37 to 40 degrees, allergies in the background infectious disease It won’t just go away, even when the body is exposed to antipyretics.
Unstable body temperature can be a dangerous sign for human health, causing dizziness, difficulty breathing, stomach cramps, nausea, and collapse.
Only timely medical care can be the key to diagnosing the disease and speedy recovery.

How to distinguish it from other diseases
If we talk about related symptoms, it is worth noting some differences between similar symptoms.
- comparison with rubella. The rash occurs on the face, and not all over the body, as with allergies; the disease is accompanied by a high temperature, which is brought down by antipyretics, and subsides on the second day if the treatment is carried out effectively.
