allergist Interview Questions and Answers

1. What is an allergy?

   • Answer: An allergy is an abnormal reaction of the body's immune system to a normally harmless substance, called an allergen. This reaction can manifest in various ways, from mild skin irritation to severe life-threatening anaphylaxis.

2. What are common allergens?

   • Answer: Common allergens include pollen (trees, grasses, weeds), dust mites, pet dander, mold spores, certain foods (peanuts, milk, eggs, shellfish), insect stings (bees, wasps), and medications.

3. How is an allergy diagnosed?

   • Answer: Diagnosis typically involves a detailed medical history, physical examination, and allergy testing. Testing may include skin prick tests, blood tests (RAST), or food challenges.

4. What are the symptoms of an allergic reaction?

   • Answer: Symptoms vary depending on the allergen and the severity of the reaction. They can range from mild (itchy eyes, runny nose, sneezing) to severe (hives, swelling, difficulty breathing, anaphylaxis).

5. What is anaphylaxis?

   • Answer: Anaphylaxis is a severe, life-threatening allergic reaction that causes a rapid drop in blood pressure, difficulty breathing, and potential loss of consciousness. It requires immediate medical attention.

6. What is the treatment for allergies?

   • Answer: Treatment options vary depending on the allergen and the severity of the reaction. They may include avoidance of the allergen, antihistamines, decongestants, corticosteroids, immunotherapy (allergy shots), and epinephrine (for anaphylaxis).

7. How does immunotherapy work?

   • Answer: Immunotherapy, or allergy shots, involves gradually introducing increasing doses of the allergen to desensitize the immune system and reduce the allergic response over time.

8. What are the side effects of allergy medication?

   • Answer: Side effects vary depending on the medication but can include drowsiness, dry mouth, nausea, and others. It's crucial to discuss potential side effects with a doctor.

9. Can allergies be prevented?

   • Answer: While not always preventable, minimizing exposure to known allergens can significantly reduce symptoms. This might involve dust mite control, pet avoidance, or careful diet management.

10. How common are food allergies?

    • Answer: Food allergies are relatively common, particularly in children. The prevalence varies depending on the specific food and geographic location.

11. What is the difference between an allergy and an intolerance?

    • Answer: An allergy involves the immune system, leading to a potentially severe reaction. An intolerance is a digestive problem causing discomfort but not a life-threatening immune response.

12. What should I do if I suspect I'm having an allergic reaction?

    • Answer: Remove yourself from the allergen source. Take any prescribed medication (like an epinephrine auto-injector). Seek immediate medical attention if symptoms are severe or worsening.

13. How long does it typically take for allergy symptoms to appear after exposure?

    • Answer: This varies greatly depending on the allergen and the individual. It can range from minutes to hours or even days.

14. Can allergies develop later in life?

    • Answer: Yes, it's possible to develop allergies at any age, though they are more commonly diagnosed in childhood.
