Hear this out loudPauseAn allergen is a substance that can cause an allergic reaction. In some people, the immune system recognizes allergens as foreign or dangerous. As a result, the immune system reacts by making a type of antibody called IgE to defend against the allergen.

Allergies, also known as allergic diseases, are a number of conditions caused by hypersensitivity of the immune system to typically harmless substances in the environment….

Allergy
Types Hay fever, food allergies, atopic dermatitis, allergic asthma, anaphylaxis
Causes Genetic and environmental factors

Treatments for allergic rhinitis

  1. Antihistamines. You can take antihistamines to treat allergies.
  2. Decongestants. You can use decongestants over a short period, usually no longer than three days, to relieve a stuffy nose and sinus pressure.
  3. Eye drops and nasal sprays.
  4. Immunotherapy.
  5. Sublingual immunotherapy (SLIT)

What’s the difference between an allergic reaction and an intolerance?

IgEs are allergic antibodies. They cause an immediate reaction when chemicals, like histamine from mast cells, are released. Food allergies can be fatal, unlike a food intolerance or sensitivity. In extreme cases, ingesting or even touching a small amount of the allergen can cause a severe reaction.

How are Allergies related to the immune system?

A chronic disease lasts a long time or occurs often. An allergy occurs when the body’s immune system sees a substance as harmful and overreacts to it. The substances that cause allergic reactions are allergens. When someone has allergies, their immune system makes an antibody called immunoglobulin E (IgE).

What’s the difference between an IgE and a food allergy?

In extreme cases, ingesting or even touching a small amount of the allergen can cause a severe reaction. Symptoms of food allergy include:

What is the difference between autoimmune and allergy?

While allergies and autoimmune diseases cause similar reactions in the immune system, they are two different conditions. The main difference between them is the trigger: allergies are a response to external triggers (certain foods or pollens), whereas autoimmune diseases are a response to internal triggers (the body’s own cells).

What are the four types of allergic reactions?

There are four types of allergic (hypersensitivity) reactions based on the mechanism of the reaction. The types I, II, and III allergic reactions are antibody mediated reactions, while type IV is a T-cell mediated reaction.
