Can you explain chronic allergic disease?

Chronic allergic disease refers to a long-term condition in which the immune system reacts abnormally to harmless substances such as dust, pollen, animal dander, or certain foods. This reaction causes ongoing inflammation in organs such as the skin, lungs, or nasal passages, leading to symptoms such as sneezing, a runny nose, coughing, itching, rashes, or breathing difficulty. Common examples include allergic rhinitis, asthma, and eczema. The condition tends to persist or recur over time, especially when exposed to triggers. Proper diagnosis through allergy testing and long-term management with medicines, avoidance of known triggers and lifestyle changes can help control symptoms and improve quality of life.

I frequently get a cold in the summer after being exposed to AC. How can I prevent this?

Cold symptoms after exposure to air conditioning (AC) are often caused by dry air irritating your nasal lining or sudden temperature changes. Avoid direct AC airflow, keep the room temperature moderate, and cover your neck and chest. Staying well hydrated and supporting your immunity with proper sleep and a balanced diet can also help prevent frequent colds.

What are common allergy symptoms?

Allergy symptoms can affect the nose, eyes, skin, lungs, and digestive system, ranging from mild irritation (sneezing, itching, watery eyes) to severe, life-threatening reactions (anaphylaxis with throat swelling and breathing difficulty). These symptoms vary depending on the allergen (pollen, dust, food, insect stings, medications) and the route of exposure.

I am allergic to dust, and I keep sneezing continuously until the room is cleaned or I go outside for some fresh air. What can I do to manage this allergy?

To manage dust allergies, keep your home clean and well-ventilated, use a HEPA filter if possible, wash your bedding in hot water, and stay away from dusty areas. You may take over-the-counter antihistamine tablets (such as cetirizine or fexofenadine) or use a saline nasal spray to clear dust particles from your nose. If the allergy persists despite these measures, please consult your doctor for advice.

I have developed rashes on my face and below my neck after riding my bike for about two hours. What treatment would help relieve the rash quickly?

Rashes after outdoor activities may be caused by heat, sweat, sun exposure, or dust irritation. Gently wash the affected area with clean water, keep it dry, and apply a mild soothing lotion, such as calamine, to reduce irritation. If the rash does not improve or if there is severe itching or swelling, please consult a doctor for proper treatment.

I have irritation in my left nostril when I breathe in, along with itching, a runny nose, and chest infections. What should I do?

Your symptoms may be due to an underlying allergy, dryness, or a nasal infection such as sinusitis. You should consult an ENT doctor for proper examination and treatment. Try to avoid dust and cold air, and use a saline nasal spray to keep your nasal passages moist and help clear allergens until you are examined.
