Allergic reaction: what is it and how to recognize it?

An allergic reaction is the general name for clinical manifestations of increased sensitivity of the body to an allergen. Allergens can be a variety of substances such as pollen, dust, foods, medications, animal hair and many others.

When an allerene enters the body, the immune system begins to produce antibodies that protect the body from its effects. However, upon repeated exposure to the allerene, the immune system may overreact, causing an allergic reaction.

Symptoms of an allergic reaction can range from mild to severe, including runny nose, cough, itchy skin, red eyes, swelling of the throat, nausea, vomiting and even anaphylactic shock. Some people may have more than one type of allergy, which can make diagnosis difficult.

Diagnosis of an allergic reaction may include skin tests, blood tests, and allergen testing. Treatment may include medications such as antihistamines, medications to reduce inflammation, and epinephrine for anaphylactic shock. In severe cases, hospitalization may be required.
