It is World Asthma Day. Let us all join hands and control it.
Remember 'Prevention is the best strategy'
Asthma is a disease of the airways in the lungs.
You can get asthma at any age. You can not catch asthma from other people. Many times more than one person in the same family has asthma.
Airways carry air to the lungs. Airways get smaller and smaller like branches of a tree.
When asthma is under control, the airways are clear and air flows easily in and out.
When asthma is not under control, the sides of the airways in the lungs are
always thick and swollen and an asthmatic attack can happen easily.
During an asthma attack, less air can get in and out of the lungs. People a cough and wheeze. The chest feels tight.
The sides of the airways get even more swollen, squeezed and start to make mucus.
