Understanding Extrinsic Asthma

Asthma has a long history and has been a great physical problem for the mankind during ancient times. The investigations revealed its characteristics and negative effects for the human body. Medical researchers have explored this infection over the years and successfully acquired knowledge regarding different forms of the disease. They also devised several techniques for the classification of the disease into different form. They also successfully distinguished one form of asthma from others. The article provides comprehensive review of the different classes. Medically, the asthma is divided into two major classes called extrinsic and intrinsic asthma. This classification is based on the triggering agent or stimulus that starts the episodes of the infection. Extrinsic asthma can be described as allergic asthma in nature because it covers all types of infection that are triggered by allergies.

Other terms that doctors use to describe this category of asthma include allergic asthma and atopic asthma. Allergy refers to the response of the human body or its parts to something that is inhaled, ingested or taken in the form of medicine. Therefore, atopic asthma is clearly linked with allergy caused by certain substances. These substances are named as allergens that cause reactions in the human body and negatively affect some parts, especially the respiratory tract.

Extrinsic Asthma is triggered by allergens and it is important for everyone to know the major and different things to which his or her body shows allergic reactions. The disease is prevalent in almost all parts of the world. In tropics and subtropics, the most common allergens include pollens from grass and trees. These pollens get into the air and then enter into the respiratory canal of the allergic people and result allergies that ultimately lead into the attack of asthma.

Other allergens for extrinsic asthma include molds and animal dander. The people who have pets should keep their children away from them because animal dander has been reported as the most common allergen that causes asthma in children. Moreover, the mites are also present on the animal body and may enter the respiratory system through inhalation near the pets. Children who participate in sports activity should stay away from the dust because dust may contain dust mites, and if inhaled it can cause allergy resulting in attack of asthma.

There are some interesting stats and figures regarding extrinsic asthma are given below. Most of the people that get infected from this disease in childhood suffer from atopic asthma. Allergies have been reported to be cause of disease in almost 90 percent of the asthmatic patients (with age less than 16 years). Similarly 70 percent of patients aging between 16 to 30 years also have allergies. These stats are released by health institutes of the USA and WHO (World Health organization). The symptoms greatly vary for this category and are accompanies by skin conditions or hay fever. In the end, you can use this information to keep your children away from the sources of infection and share it with your friends.
