3. Food Allergens:

   - Common food allergens: Milk, eggs, nuts, seafood, wheat, soy.  

4. Animal Dander: Hair or dead skin flakes from pets like cats and dogs.  

5. Medications: Penicillin, aspirin, or certain antibiotics can trigger reactions.  

6. Chemicals: Detergents, perfumes, cleaning products.

Diagnosis of Allergies

Doctors use several methods to identify allergies:

1. Medical History:

   - A detailed history of symptoms, diet, and environmental exposure.  

2. Skin Prick Test:

   - Small amounts of allergens are applied to the skin to check for reactions such as redness or swelling.  

3. Blood Test:

   - Measures the levels of Immunoglobulin E (IgE) in the blood.  

4. Elimination Diet:  

   - Suspected food allergens are removed from the diet to observe symptoms.  

5. Patch Test:

   - Chemicals or substances are applied to the skin to check for delayed allergic reactions.

Treatment of Allergies

While allergies cannot be cured permanently, symptoms can be managed effectively.  

1. Medications:

1. Antihistamines:  

   - Example: Loratadine, cetirizine.  

   - Relieves symptoms like sneezing, itching, and runny nose.  

2. Decongestants:

   - Example: Pseudoephedrine.  

   - Helps clear nasal congestion.  

3. Steroids:

   - Example: Fluticasone spray.  

   - Reduces inflammation in nasal allergies.  

4. Allergy Shots (Immunotherapy):

   - A long-term treatment to build tolerance against allergens.  

5. Epinephrine Injection (EpiPen):  

   - Used in emergencies to treat anaphylaxis.  

2. Preventive Measures:

1. Avoid exposure to allergens.  

2. Maintain a clean, dust-free environment.  

3. Eliminate allergenic foods from your diet.  

4. Keep pets away if allergic to animal dander.  

5. Regularly wash bedding and vacuum floors.  

3. Natural Remedies:

Conclusion

Allergy is a common but manageable condition. Identifying allergens and taking preventive measures are essential for minimizing its impact on daily life. By consulting a healthcare provider, adopting a proper treatment plan, and making necessary lifestyle changes, the severity and frequency of allergic reactions can be significantly reduced.
