Perennial rhinitis is due to house dust. It should be treated throughout the year. Bronchial asthma is also increasing because of dust and air pollution. People who suffer allergic attacks generally have a family history of allergies. People with allergies may have elevated IGE levels.
Intestinal allergies happen due to certain foods.
The IGE levels state the level of allergic ness to an allergen. The higher the IGE levels the higher a person's allergy towards an allergen. Hyposensitisation can help make a person less sensitive to allergen. Hyposensitisation is the process of making the patient less sensitive to an antigen. The emphasis is on hyposensitisation and not desensitisation.
