Nature of the problem.
Asthma is a respiratory disease where the narrowing of a person's airways causes difficulty in breathing. This happens because;
- the inside lining of the airways becomes swollen.
- the muscles around the airways tighten.
- increased mucus secretion partially blocks the airways.
