Asthma is a chronic disease that affects your airways. Your airways are tubes that carry air in and out of your lungs. If you have asthma, the inside walls of your airways become sore and swollen. That makes them very sensitive, and they may react strongly to things that you are allergic to or find irritating. When your airways react, they get narrower and your lungs get less air.
Symptoms of asthma include:
- Coughing, especially early in the morning or at night
- Chest tightness
- Shortness of breath
Not all people who have asthma have these symptoms. Having these symptoms doesn't always mean that you have asthma. The doctor will diagnose asthma based on lung function tests, your medical history, and a physical exam. It may also be required to take some allergy tests.
Asthma is a very prevalent disease in our country, and is treated primarily by quick-relief medicines to stop asthma symptoms and long-term control medicines to prevent symptoms.
