Asthma

Asthma is sudden inflammation of the air passages of the lungs. It arises on account of exposure to the allergens in the body. It is a form of hypersensitive reaction. The air passages respond to the allergens entering the respiratory pathway and start secreting excessive amounts of mucus. This mucous will obstruct the passage of the oxygen into the blood and hence the person will gasp for more air. The signs of asthma include blue fingers, lips and nails, sudden suffocation and desire to be in open air, cough and gagging. Patient will not have any flu, cough or any other ailment prior to the attack but will start sudden cough and gagging.
