Allergies are your body’s reaction to normally harmless substances. Allergy symptoms range from mild to life-threatening. Treatments include antihistamines, decongestants, nasal steroids, asthma medicines and immunotherapy.
Allergies are your body’s reaction to a foreign protein. Usually, these proteins (allergens) are harmless. However, if you have an allergy to a particular protein, your body’s defense system (immune system) overreacts to its presence in your body.
An allergic reaction is the way your body responds to an allergen. If you have allergies, the first time you encounter a specific allergen, your body responds by creating immunoglobulin E (IgE). Your immune system makes antibodies to form IgE.
