A person can develop allergic symptoms when their immune system over reacts whenever the body comes in contact with an allergen. If the immune system is oversensitive it will react to allergens by producing antibodies to fight with them. Antibodies make the cells to release some chemicals including histamine.
Histamine cause the mucus membrane to become inflamed and produce excess mucus which in turn results in running nose, stuffiness, sneezing, itching of nostrils and eyes. This is termed as allergic rhinitis.
Allergic rhinitis may be seasonal or perennial. Seasonal allergies usually occur for a certain season where allergens like pollens are very high. Perennial allergies can occur year around in response to indoor allergens and pollution.
Allergies can affect anyone .People who have family history of atopy, dust allergy or asthma can increase the risk of allergic rhinitis.
