Asthma is caused by the inflammation of bronchial tube and results in difficulty in breathing. Most of the cases of asthma are noticed in children below 10. Asthma is of two types- intrinsic and extrinsic. The extrinsic asthma is caused by an external agent like irritant. On the other hand, when an external agent is not recognized for the occurrence of the disease, it is referred to as intrinsic asthma.
Some people are allergic to substances like pollens, food, dust or molds. This allergy can be responsible for the initiation of extrinsic asthma in patients. On the other hand the reason behind intrinsic asthma is generally a respiratory infection. The intrinsic asthma is believed to worsen due to conditions like stress and anxiety. The asthma attacks vary in intensity but they generally require the patient to take an inhalant immediately. In case of severe asthma a person may die, if proper remedial measures are not provided on time.
