Asthma

 

Asthma is a chronic long-term 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.

Understanding Asthma

To understand asthma, it helps to know how the airways work. The airways are tubes that carry air into and out of your lungs. People suffering from asthma have inflamed airways. The inflammation makes the airways swollen and very sensitive. The airways tend to react strongly to certain inhaled substances exercise or cold air.
When the airways react, the muscles around them tighten. This narrows the airways, causing less air to flow into the lungs. The swelling also can worsen, making the airways even narrower. Cells in the airways might make more mucus than usual. Mucus is a sticky, thick liquid that can further narrow the airways. This chain reaction can result in asthma symptoms. Symptoms can happen each time the airways are inflamed.

Sometimes asthma symptoms are mild and go away on their own or after minimal treatment with asthma medicine. Other times, symptoms continue to get worse. When symptoms get more intense and/or more symptoms occur, you’re having an asthma attack. Asthma attacks also are called flareups or exacerbations.

Treating symptoms when you first notice them is important. This will help prevent the symptoms from worsening and causing a severe asthma attack. Severe asthma attacks may require emergency care, and they can lead todeath.

Asthma has no cure. Even when you feel fine, you still have the disease and it can flare up at any time. However, with today’s knowledge and treatments, most people who have asthma are able to be completely controlled so that they can live a normal life, this includes participation in sports and other physical activities. If you have asthma, you can take an active role in managing the disease. For successful, thorough, and ongoing treatment, build strong partnerships with your doctor and other health care providers.
