A food allergy is an abnormal immune response to food. The symptoms of the allergic reaction may range from mild to severe. They may include itchiness, swelling of the tongue, vomiting, diarrhea, hives, trouble breathing, or low blood pressure. This typically occurs within minutes to several hours of exposure.
Food intolerance is a detrimental reaction, often delayed, to a food, beverage, food additive, or compound found in foods that produces symptoms in one or more body organs and systems, but generally refers to reactions other than food allergy. Food hypersensitivity is used to refer broadly to both food intolerances and food allergies.
Hypersensitivity (also called hypersensitivity reaction or intolerance) is an abnormal physiological condition in which there is an undesirable and adverse immune response to antigen. [1] [2] It is an abnormality in the immune system that causes immune diseases including allergies and autoimmunity. It is caused by many types of particles and ...
Is it a food allergy, sensitivity or intolerance? Here's how to tell, according to experts.
Allergies, also known as allergic diseases, are various conditions caused by hypersensitivity of the immune system to typically harmless substances in the environment. These diseases include hay fever, food allergies, atopic dermatitis, allergic asthma, and anaphylaxis.
Type I hypersensitivity (or immediate hypersensitivity ), in the Gell and Coombs classification of allergic reactions, is an allergic reaction provoked by re-exposure to a specific type of antigen referred to as an allergen. [1] Type I is distinct from type II, type III and type IV hypersensitivities.
Immunology. Type IV hypersensitivity, in the Gell and Coombs classification of allergic reactions, often called delayed-type hypersensitivity, is a type of hypersensitivity reaction that can take a day or more to develop. [1] Unlike the other types, it is not humoral (not antibody -mediated) but rather is a type of cell-mediated response.
Avoidance of antigen exposure and sometimes steroids. Hypersensitivity pneumonitis ( HP) or extrinsic allergic alveolitis ( EAA) is a syndrome caused by the repetitive inhalation of antigens from the environment in susceptible or sensitized people. [1] [2] Common antigens include molds, bacteria, bird droppings, bird feathers, agricultural ...
A food intolerance differs from a food allergy or chemical sensitivity because it generally requires a normal serving size to produce symptoms similar to an IgE immunologic response. While food intolerances may be mistaken for a food allergy, they are thought to originate in the gastrointestinal system.
Coeliac disease ( British English) or celiac disease ( American English) is a long-term autoimmune disorder, primarily affecting the small intestine, where individuals develop intolerance to gluten, present in foods such as wheat, rye and barley. [10] Classic symptoms include gastrointestinal problems such as chronic diarrhoea, abdominal ...
