Allergology is the branch of medicine that focuses on diagnosing and treating allergies and related conditions. Allergists, or specialists in this field, study how the immune system reacts to various substances, known as allergens, which can include pollen, dust mites, pet dander, and certain foods. Patients often seek help for symptoms like sneezing, itching, or skin rashes. Allergology also addresses more severe reactions, such as anaphylaxis, which can be life-threatening. Treatments may involve medications, allergy shots, or lifestyle changes to minimize exposure to allergens, improving the quality of life for those affected.
