Allergic Conditions

Allergic conditions are common and increasing cause of illness. In an allergic reaction, first exposure to an otherwise harmless exogenous substance triggers the production of specific IgE antibodies by activated B cells and binds to mast cells. Upon re-exposure, allergen activates mast cells releasing a variety of vasoactive mediators. The severity of allergies varies from person to person and can range from minor irritation to anaphylaxis, a potentially life-threatening emergency. While most allergies can’t be cured, treatments can help relieve allergy symptoms.
