Asthma is a life-threatening chronic condition in which the lung tissues are inflammed and the airways are obstructed. 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. In the USA, more than 25 million people are known to have asthma. About 7 million of these people are children. In Singapore, about 5% of adults and 20% of children have asthma. India has an estimated 15-20 million asthmatics. The numbers are alarming.
Asthma is essentially the obstruction of airways in the lungs due to various factors including tobacco smoke, dustmites, air pollution, various allergens including pets’ hair, mold, smoke from burning wood, respiratory infections, flu, bad weather, haze, physical exercise, stress (mental/emotional), physical exertion and pollen. Tropical countries like Singapore, have many asthmatics who have an asthma attack when plants pollinate.
