Allergic reactions occur when the body overreacts in its response to fighting off an allergen, such as pet dander, pollen, or a food.
Some allergic reactions manifest as a skin rash, but others can cause uncomfortable flare ups that require medical treatment and intervention.
Types of Allergic Reactions and Symptoms
There are several types of allergic reactions people can experience after exposure to an allergen. While many allergic reactions resolve on their own once the allergen is no longer present, some can require treatment with medication.
Rashes are a highly common reaction to an allergen such as poison ivy, or an insect sting or bite.This type of rash typically manifests as hives, which are raised areas around the skin that can be itchy. They typically go away on their own once the allergen has been removed, but can require antihistamines to control the body’s reaction.
These allergic reactions result in the release of histamines in the body that cause inflammation and swelling. These reactions manifest as food allergies, bronchial asthma, rhinitis, or, in serious cases, anaphylaxis.
In this type of allergic reaction, cells are damaged by antibodies, causing conditions like anemia, thrombocytopenia, and neutropenia.
In this type of allergic reaction, antibodies react with the allergen to form immunocomplexes, such as lupus.
These types of allergic reactions occur 24-48 hours after exposure to the allergen, such as nickel allergies that cause skin irritations, and the reaction may last for several hours even after the allergen is removed.
