What Causes Allergies?
Allergies are an overreaction of the immune system to an allergen, which can be anything from pollen to food or pet dander. When a person is exposed to the allergen, their body releases a chemical called histamine which causes the symptoms of an allergic reaction, such as sneezing, runny nose, itchy eyes, and a scratchy throat.
How Fast Do Allergies Go Away?
The speed at which allergies go away depends on the severity of the reaction and the allergen that is causing it. For mild allergies, such as hay fever, symptoms can usually be managed with over-the-counter medications and can go away in a few days. But for more severe allergies, such as those caused by bee stings or certain foods, a visit to the doctor may be necessary to get the proper treatment and relief. Additionally, allergies can be seasonal, so the symptoms may come back when the seasons change.
