Understanding Allergies

Allergies occur when the immune system overreacts to harmless substances. They affect millions of people and can range from mild annoyances to life-threatening emergencies. Understanding allergies helps manage symptoms and prevent reactions.

Common Allergens

Food allergens include peanuts, tree nuts, milk, eggs, wheat, soy, fish, and shellfish. Environmental allergens include pollen, dust mites, mold, and pet dander. Insect stings and medications can also cause allergic reactions.

Management and Treatment

Prevention involves avoiding known allergens. Medications including antihistamines and nasal sprays manage symptoms. Severe reactions require epinephrine and emergency care. Allergy testing identifies specific triggers. Immunotherapy can desensitize some people.
