Allergies

Allergies are the body's reactions to normally harmless substances such as pollen, mold, animal fur, latex, certain foods, and insect bites. Allergic symptoms range from mild rashes, hives, itching, runny nose, and watery/red eyes to life-threatening. Treatments include antihistamines, decongestants, nasal steroids, asthma medications, and immunotherapy.

What are allergies caused?

Allergies occur when your immune system reacts to a foreign substance — such as pollen, bee venom or pet dander — or a food that doesn't cause a reaction in most people.
