Allergic inflammation
Allergic Inflammation
Allergic inflammation (pronunciation: /əˈlɜːr.dʒɪk ˌɪn.fləˈmeɪ.ʃən/) is a type of inflammation that occurs when the immune system overreacts to allergens in the environment.
Etymology
The term "allergic" is derived from the Greek word "allergos" meaning "other work", and "inflammation" comes from the Latin "inflammare" which means "to set on fire".
Definition
Allergic inflammation is a reaction of the immune system to foreign substances, or allergens, that are not typically harmful to the body. This reaction can cause various symptoms such as itching, redness, swelling, and pain at the site of exposure.
Causes
Allergic inflammation is caused by an overreaction of the immune system to allergens. Common allergens include pollen, dust mites, mold, pet dander, and certain foods.
Symptoms
Symptoms of allergic inflammation can vary depending on the type of allergen and the individual's immune response. Common symptoms include redness, swelling, itching, and pain. In severe cases, allergic inflammation can lead to anaphylaxis, a potentially life-threatening reaction.
Treatment
Treatment for allergic inflammation typically involves avoiding the allergen, if possible, and taking medications to manage symptoms. These may include antihistamines, corticosteroids, and immunotherapy.
