Asthma, you may be aware of, is a common and potentially life threatening airway condition which is marked by the inflammation in the lungs causes narrow, swollen airways, increased production of sticky secretions inside the tubes, shortness of breath, chest tightening, coughing especially at night and wheezing. But do you know there are different types of asthma? It is divided to two categories namely intrinsic and extrinsic. Treatment for intrinsic asthma is difficult as the causative agent is not known while in case of extrinsic asthma, the situation can be improved by restricting the allergens. Intrinsic asthma is caused by extremes of feelings like laughing, crying or exposure to chemicals like cigarette smoke, aspirin, cleaning agents or chest infection or exercises. Exercise induced asthma is a subtype of intrinsic asthma and is generally seen immediately post exercise. Another subtype of asthma known as nocturnal asthma is observed in the early hours of the night, however, this subtype if common in both extrinsic and intrinsic asthma patients. It is of utmost importance to seek treatment for this type of asthma in order to prevent deaths due to asthma in sleep. Extrinsic asthma also referred as allergic asthma as it is triggered by allergens. In extrinsic asthma, immune system exerts a protective mechanism when it suspects that you are exposed to harmless substances such as pollen and produces antibodies which results in hay fever, rhinitis and asthma. As an outcome of allergic reaction, a large amount of mucus is produced in the lungs that obstruct the air passage. Symptoms of extrinsic asthma include coughing, wheezing, chest pain due to pressure and heaviness.  Although no permanent cure is available for extrinsic but the symptoms can be controlled by avoiding exposure to allergens that could trigger asthma.
