Common Causes of Allergies

Allergies occur when the body's immune system mistakenly identifies a harmless substance as a threat and overreacts to it. Some common causes of allergies include:

1. Pollen

Pollen is a common allergen, especially during spring when trees and flowers release pollen into the air. People with pollen allergies may experience symptoms such as sneezing, runny nose, and itchy eyes.

2. Dust Mites

Dust mites are tiny insects found in household dust. Their waste and body parts can trigger allergic reactions in some people, leading to symptoms like coughing, wheezing, and skin rashes.

3. Pet Dander

Pet dander consists of tiny flecks of skin shed by animals like cats and dogs. Allergic reactions to pet dander can cause symptoms such as nasal congestion, itching, and respiratory issues.

4. Mold

Mold spores are common in damp and humid environments. Inhaling mold spores can lead to allergic reactions, including coughing, sneezing, and watery eyes.

5. Food

Certain foods can cause allergic reactions in some individuals. Common food allergens include nuts, shellfish, eggs, and dairy products. Symptoms can range from mild itching to severe anaphylaxis.

Identifying and avoiding allergens is key to managing allergies and reducing symptoms. Consultation with an allergist can help in diagnosing specific allergens and developing a personalized treatment plan.
