Which organs do allergens mainly affect?

The primary organs affected by allergens are:

1. Airways and Lungs: Allergens such as pollen, dust, and pet dander commonly trigger allergic reactions in the respiratory system. They cause the release of inflammatory mediators like histamine, leading to symptoms such as sneezing, runny nose, itchy eyes, and difficulty breathing.

2. Skin: Allergens like certain metals, chemicals, and plants can cause skin allergies, resulting in various skin conditions such as contact dermatitis, eczema, and hives (urticaria).

3. Digestive System: Food allergies occur when the immune system overreacts to specific food proteins, leading to symptoms such as abdominal pain, nausea, vomiting, and diarrhea.

4. Eyes: Allergic conjunctivitis, commonly known as hay fever or allergic rhinitis, affects the eyes, causing symptoms such as itching, redness, swelling, and excessive tear production.

It's important to note that allergies can manifest in different ways and may affect other organs depending on the individual and the type of allergen involved. Consulting a healthcare professional is crucial for proper diagnosis, management, and treatment of allergies.
