Allergies can cause symptoms such as itching, a runny nose, sneezing, wheezing, allergic rhinitis, and asthma. But what happens inside the immune system when the body reacts to otherwise harmless substances?
In this informative video, Dr. Ashwini R, Consultant ENT at Mazumdar Shaw Medical Center, Bommasandra, Bengaluru, explains the science behind allergies and how allergen immunotherapy may help retrain the immune system to become less sensitive to specific allergens.
Dr. Ashwini explains the role of T lymphocytes, B lymphocytes, IgE antibodies, mast cells, histamine, and T-regulatory cells in the allergic response. She also discusses how conventional treatments may help control symptoms, while allergen immunotherapy is designed to address the underlying immune response through gradual, controlled exposure to allergens under medical supervision.
The video also covers potential benefits discussed in the presentation, including better control of allergic rhinitis and asthma, improved sleep, greater ability to participate in outdoor activities, and reduced dependence on sprays or inhalers in suitable patients. Treatment suitability, duration, risks, and outcomes vary from person to person and must be assessed by a qualified healthcare professional.
