Allergies are among the most common chronic conditions worldwide.
According to the leading experts in allergy research, an allergic reaction begins in the immune system. The immune system overreacts to the allergen by producing Immunoglobulin E (IgE) antibodies. These antibodies travel to cells that release histamine and other chemicals, causing an allergic reaction.
Allergy Symptoms
An allergic reaction typically triggers symptoms in the nose, lungs, throat, sinuses, ears, lining of the stomach, or on the skin. For some people, allergies can also trigger asthma symptoms. In serious cases, a life-threatening reaction called anaphylaxis can occur. A number of different allergens are responsible for allergic reactions. The most common include:
Animal Dander
Pet allergies are caused by a protein present in pet’s dander, skin flakes, saliva, and urine.
Food
Food Allergies include tree nuts, eggs, fish, shellfish, milk, soy, peanuts, and wheat and gluten allergies.
Medications
Allergies and adverse reactions to medications are common, and people can have a wide variety of allergic symptoms.
Mold
Molds are microscopic fungi made up of clusters of filaments. Many molds reproduce by releasing spores into the air.
