Why and how is asthma caused?
Asthma is a common problem of the respiratory tract. In this condition, the pipes for air passage are either narrowed or blocked. Due to this, the person finds it difficult to inhale and exhale. In severe cases, when the passage is completely blocked, the person coughs and wheezes incessantly. There are two kinds of asthma attacks. The first type is called Extrinsic Asthma or Allergic Asthma and is caused due to some kind of allergy, which might be anything ranging from dust to pollens. When the person inhales such particles asthma is caused. This is the kind of asthma that inflicts maximum number of people. The second type of asthma is called Intrinsic Asthma or non allergic asthma. This kind of respiratory problem is not caused due to allergens but due to other factors toxicity, anxiety, cold sir, stress and viruses. Essentially, asthma is caused when the bronchi are sensitive to different kinds of allergens and when the lung cannot function to their full efficiency.
