Allergies occur when your body behaves in an abnormal way to a foreign substance with which you come in contact. Usually, your body fights off any threats to your system by producing antibodies that eject the offending substance from your system.

The ejection of foreign particles will most likely result in inflamed skin, sinuses, airways, or the digestive system. Such reactions are likely to manifest as sneezing, coughing, or having watery eyes or itchy skin.

Allergies may be seasonal, which come and go through different times in the year, or they may affect you throughout the year. The difference lies in the substance your body reacts to – the allergen.

According to the Asthma and Allergy Foundation of America (AAFA), allergies are the 6th leading cause of chronic illness in the U.S.

Read about the most common types of allergies below.

Allergic Rhinitis

Allergic rhinitis is a very commonly occurring type of allergy. In 2018 alone, approximately 24 million people in the U.S. were diagnosed with seasonal allergic rhinitis (hay fever).

If you have allergic rhinitis, your immune system mistakenly identifies a typically harmless substance in your system as a threat. Allergic rhinitis, also known as hay fever, is an allergic reaction that typically causes sneezing, congestion, an itchy nose, and a sore throat.

The condition is often triggered by airborne particles, such as dust mites, mold, pet dander, and pollen from trees and plants. Allergic rhinitis, or hay fever, is not contagious.

Food Allergies

According to the U.S. Food and Drug Administration (FDA), food allergies occur when the body's immune system reacts to specific proteins in the food.

Allergic reactions can vary in severity from mild symptoms that cause hives to severe, life-threatening symptoms, like anaphylaxis.

The speed at which allergy signs and symptoms appear depends on the digestive process. These reactions may take a few minutes to a couple of hours to manifest.

As a rule, avoiding foods that cause your body to have an allergic reaction is best.

Chronic Hives

Chronic hives or chronic urticaria is a skin rash that appears as dark red, raised, itchy bumps on the skin. Chronic hives are defined by recurrent episodes occurring at least twice a week over a period of six weeks.

Chronic hives are not very common, and about 5% of people may have

them in their lifetime. The condition is usually more prevalent in women than in men.

Chronic hives do not put you at sudden risk of a severe allergic reaction (anaphylaxis). However, seek emergency care if you experience hives as part of a severe allergic reaction.
