What is an allergy?
An allergy is your immune system overreacting to something that is usually harmless — pollen, dust mites, pet dander, mold, certain foods or insect stings. North Texas has a long pollen season, so many patients notice symptoms most of the year.
What are the symptoms of allergies?
Sneezing, a runny or stuffy nose, itchy and watery eyes, cough, hives or skin rashes, and sometimes stomach upset. Severe reactions with swelling of the lips or throat or difficulty breathing need emergency care.
How are allergies diagnosed and treated?
Diagnosis starts with a careful history and exam, and may include testing to identify triggers. Treatment combines avoiding triggers with medications such as antihistamines, nasal sprays or eye drops, and a plan for emergencies when needed.
