Important Details about Allergies and Hypersensitivities
What is an allergy?
When your immune system reacts to something that is usually harmless, it can result in an allergy. substances known as “allergens” because they cause allergies.

What is a hypersensitivity reaction?
An immune system overreaction to something that normally wouldn’t trigger a defense response is known as a hypersensitive reaction. Symptoms of allergies result from this. Reactions characterized by hypersensitivity come in several forms. When exposed to an allergen, type I reactions sometimes occur within minutes, although they can also often take hours. Although they are usually reasonable, they may develop on occasion and result in anaphylaxis, a serious reaction.
Immune reactions of types II and III happen when your body targets specific body regions with an attack by your immune system. This could end up in mild to severe autoimmune disorders. “Delayed hypersensitivity reactions” is another term for type IV reactions. These responses may manifest 12 to 72 hours following allergen exposure. For instance, organ transplant rejection, type I diabetes, specific lung conditions, and contact dermatitis.

The kind of antigen and the degree of severity of the allergy determine the symptoms. The extent of the symptoms might vary from minor to fatal. Hay fever (runny nose, watery, itchy eyes), eczema (dry, red, itchy skin), spots (bumpy skin rash), and asthma (wheezing, coughing, and difficulty breathing) are a few of the disease or symptoms brought on by allergies.
Anaphylaxis, a severe form of allergic reaction, can result in difficulties with breathing, noisy breathing, swelling of the tongue, lips, and face, swelling in the throat or tightness, voice of voice, trouble speaking, coughing and wheezing, vomiting and discomfort in the stomach, disorientation, and collapse.
