Asthma
Asthma is a chronic lung disease that inflames
and narrows the airways. Asthma causes recurring periods of wheezing (a
whistling sound when you breathe), chest tightness, shortness of breath,
and coughing. The coughing often occurs at night or early in the morning. Asthma affects people of all ages, but it most often starts during
childhood.

increase your chances of developing the condition have been identified.
These include:
- childhood exposure to tobacco smoke, particularly if your mother also smoked during pregnancy
- Airborne allergens, such as pollen, animal dander, mold, cockroaches and dust mites
