The inflammed cell lining often results in thicker mucus which to further narrows the airway. Asthma is caused due to several factors like internal allergy, eczema etc. It is not completely curable and medicine need to be taken regularly. Asthma attacks can be dangerous to one's life and thus, timely treatment is required. Asthma pumps are available but experts say that it makes one dependent. It's better to try and eliminate the cause.
