Allergy give fever

A little snot and it may already be a virus. Is this so? Is there a way to differentiate viral from allergic processes? Well, let me tell you yes. The exaggerated inflammatory response suffered by a person with an allergy does not usually include one of the most typical cold symptoms, fever. Still, in addition, other manifestations can help you differentiate both processes.

Do you want to know how to know if it is an allergy, a cold, or the flu? So, keep reading this FastlyHealarticle in which we answer the question ” Does allergy give fever? “.

What is an allergy?

It is known as hypersensitivity or allergy to that excessive reaction of the immune system against substances that do not cause a response to other people.

There are allergies to countless things: from foods (such as tomatoes, honey, or fish) to mites, animal hair, or plant pollen.

The important thing is not the substance itself but your body’s overreaction to it. This reaction is usually related to other associated disorders, such as poor digestion or certain habits that promote bodily imbalances, such as unhealthy eating, insufficient sleep, or exercise.

What are the symptoms of allergies?

Allergy symptoms will depend on the part of the body that is involved. Thus, we can find various manifestations depending on the case:

Respiratory allergy

  • Nasal inflammation.
  • Nasal obstruction.
  • Clear mucus (water-like) discharge.
  • Sneezing
  • Itchy sensation in the nose.
  • Headache.
  • Dysphonia.
  • Itchy throat.
  • Hoarseness.
  • To.
  • Shortness of breath.
  • Drowning
  • High-pitched noises when inhaling (wheezing).
  • Feeling of blocked ears.
  • Clear, painless ear discharge.

Eye allergy

  • Redness
  • Itch.
  • Clear bilateral secretions.

Skin allergy

  • Itch.
  • Redness
  • Eruptions
  • Dry Skin.

Food Allergy

  • Indigestion.
  • Gases.
  • Swelling.
  • Abdominal pain.
  • Diarrhea.

These symptoms generally appear in direct contact with a particular substance and sometimes even more than one substance, either by inhaling, ingesting, or touching it.

Can allergy give fever?

Allergy is more of an inflammatory process. Upon contact with a particular substance or more than one in certain cases, the person triggers a cascade of reactions that put the body on alert.

Often, the substance called allergen is harmless for others. Most people who come into contact with it do not have any reaction. Still, the reaction can be critical in the allergic person: most of the time annoying and sometimes even lethal, but luckily this is the least of the cases.

Various substances begin to circulate in the blood intended to defend the body from an attack in an allergic reaction. Still, ultimately, that “solution” that the body gives is worse than its suffering attack. It is as if you wanted to kill an ant with a war tank—a disproportionate reaction to the small stimulus of the allergenic substance. So: allergen is not an important thing. The terrible thing is the inflammation with which a person suffering from allergy reacts.

What is fever?

Fever is a rise in body temperature above 38 ° C. If the temperature is between 37.5 ° C and 38 ° C, it is called a low-grade fever.

This usually presents with some of the following bodily manifestations:

  • Body pain.
  • Shaking chills.
  • Headache.
  • Lack of appetite.
  • Soft spot.

Other symptoms may appear already related to the specific cause of the increase in body temperature.

As seen in the previous section, allergies do not usually lead to fever. Fever is not a typical symptom of an allergic reaction.

Fever can respond to many other causes, among the most common reasons for rage are:

  • Infection.
  • Heatstroke.
  • Autoimmune disease
  • Generalized inflammatory disease.
  • Some drugs (such as antihypertensives, anticonvulsants, or even antibiotics).
  • A lump.

Sometimes the cause of the fever is not found, but it is not usually related to allergy.

One possibility of a fever occurring with an allergy is an overlapping infection. For instance:

  • In a case of allergic rhinitis (with clear mucus, sneezing, itchy nose, always at the same time of year), that lasts over time and generates a significant nasal obstruction. Over time, if this nasal inflammation persists, mucus can accumulate in a paranasal sinus and give rise to rhinosinusitis that could lead to fever in some cases and especially in children.
  • Faced with an allergic skin rash that is very itchy, the person scratches incessantly until they hurt themselves. If these lesions become infected, fever and pain may appear in the lesions, probably suppurating.

How to know if it’s the flu or allergy

To differentiate the flu from respiratory allergy, you can consider the following parameters. It is an allergy, and it is not the flu if :

  • There is no fever.
  • It does not hurt the body.
  • You tend to have episodes of this type simultaneously each year.
  • Symptoms start immediately after you contact a substance that usually causes you to be allergic.
  • Symptoms come and go, and for example, they increase when you expose yourself to the air.
  • Your throat, nose, or eyes are itchy.

Cold or flu symptoms can begin more abruptly and are often accompanied by fever, and the symptoms that often accompany fever include lightheadedness, body aches, and poor appetite.
