Asthma 

ASTHMA IS . . .Asthma is a respiratory disease in which the bronchioles (the tubes that carry air from the windpipe to the tiny airsacs in the lungs) tighten and become partially blocked, resulting in wheezing and a sensation of being starved of oxygen.

SIGNS AND SYMPTOMS OF ASTHMA: Shortness of breath Wheezing Cough Tightness in the chest Difficulty breathing

ASTHMA IS DIAGNOSED BY:Asthma is diagnosed by taking a complete medical history and physical exam, chest x-ray and blood tests. If results suggest Asthma, lung (pulmonary) function tests and sometimes allergy tests can help pinpoint the diagnosis. Sometimes, exposing the patient to a suspected triggering factor to see if it provokes an asthmatic reaction is a helpful diagnostic tool. Common triggers include air pollutants and irritants, strong odors such as perfume, cleaning products, paint, fumes etc.

ASTHMA IS TREATED BY:Asthma is treated by avoiding triggering factors, increasing exercise endurance, and using medications, both to prevent and treat an attack. The most frequently prescribed medications are bronco-dilators in the form of inhalers and anti-inflammatory medications such as steroids for acute attacks.Asthma generally does not lead to permanent damage. If left untreated, however, a severe attack can be life threatening. Get to the nearest hospital emergency room immediately if symptoms are acute. 

TO PREVENT OR AVOID ASTHMA:

Eliminate as many irritants and allergens from the environment as possible. Don’t smoke, and avoid being in the presence of smokers. Stay indoors during periods of high air pollution or when it is very cold. Exercise regularly but avoid high-endurance activities such as long distance running. Swimming or brisk walking are excellent exercise choices for persons with asthma.

If you think you might be suffering from asthma see your doctor for evaluation and treatment.
