An allergist diagnoses and treats immune system reactions to things like dust, food, medication, or insect stings. See one if you have recurring allergy or asthma symptoms, or a strong reaction that doesn't improve with over-the-counter treatment.

What is an allergist?
An allergist (also called an allergist/immunologist) is a physician who specializes in diagnosing and treating allergies and asthma. They study how your immune system reacts to specific substances — allergens — and help you manage that reaction.
Allergists also treat related immune conditions such as atopic dermatitis and some immune deficiencies.
When should I see an allergist?
- Sneezing, nasal congestion, or itching that comes back seasonally or year-round.
- Hives, skin itching, or swelling with no clear cause.
- Coughing, wheezing, or shortness of breath (possible asthma).
- A strong reaction after eating certain foods.
- A significant reaction after an insect sting or a medication.
- Allergies diagnosed elsewhere that aren't improving with your current treatment.
Conditions treated
- Allergic rhinitis (seasonal or year-round)
- Allergic asthma
- Food allergies
- Drug allergies
- Insect sting allergies
- Hives (urticaria) and angioedema
- Atopic dermatitis
- Chronic sinusitis related to allergies
What to expect at your first appointment
Your allergist will review your symptom history: when episodes happen, what triggers them, and how often.
They may recommend skin or blood tests to identify the specific allergen — this depends on your case, not every patient needs them.
Based on the results, they'll walk you through a treatment plan, which may include medication, changes to your environment, or, in some cases, long-term allergy immunotherapy (allergy shots).
