What is Asthma?

Asthma is a lung disease in which normal airflow into and out of lungs is impaired. Smoke, exercise, cold air, infection, mold, dust, and mites, for example, make lung airway cells produce more mucus. The mucus becomes thicker and more sticky, and breathing tubes (airways) clog up and become very small. This causes wheezing and shortness of breath.

Early-onset asthma (extrinisic or allergic, asthma) has both genetic and enviromental causes. Late-onset asthma (intrinsic asthma), in adults older tahn 35, can be triggered by infections and exercise.

DOs and DON'Ts in Managing Asthma:

  The DOs

• DO always carry your inhaler with you.


• DO visit your doctor regularly.


• DO use the peak flow meter to measure the amount of air you take in when you breathe. Keep records of the amounts and bring them to your doctor appointments.


• DO get a yearly flu shot and pneumococcal vaccine.


• DO continue normal activities as tolerated.


• DO exercise regularly, but make sure your asthma is controlled before starting new exercises.


• DO reduce the dust mites in your house. For example, this can be done by getting rid of carpets and using special (HEPA) filters.


• DO talk to your doctor about how your pet may affect asthma.


• DO tell your doctor if your medicines do not control your asthma or have side effects, if your peak flow readings always go down, or if you feel more tired.


• DO avoid stress.

The DONTs

• DON'T take aspirin and other over-the-counter medicines unless your doctor approves them.


• DON'T come into contact with asthma triggers such as cold air or smoke. Asthma may be related to cigarette smoke exposure.


• DON'T do excessive exercise.
