#Allergies

Allergies are hypersensitivity reactions by the immune system to normally harmless substances called allergens. These can include pollen, dust mites, certain foods, insect venom, or pet dander, leading to a wide range of symptoms. Symptoms vary depending on the allergen and can affect the skin, respiratory system, or gastrointestinal tract. Seasonal allergies typically occur during specific times of the year, while perennial allergies persist year-round. Management focuses on allergen avoidance, antihistamines, and other symptomatic treatments.
