About Asthma

Asthma is a lung condition that causes difficulty breathing, and it's common among kids and teens. Symptoms include coughing, wheezing, and shortness of breath. Anyone can have asthma, even infants, and the tendency to develop the condition is often inherited.
Asthma affects the bronchial tubes, or airways. When someone breathes normally, air is taken in through the nose or mouth and then goes into the trachea (windpipe), passing through the bronchial tubes, into the lungs, and finally back out again.
But people with asthma have inflamed airways that produce lots of thick mucus. They're also overly sensitive, or hyperreactive, to certain things, like exercise, dust, or cigarette smoke. This hyperreactivity causes the smooth muscle that surrounds the airways to tighten up. The combination of airway inflammation and muscle tightening narrows the airways and makes it difficult for air to move through.


More than 23 million people have asthma in the United States. In fact, it's the No. 1 reason kids chronically miss school. And flare-ups are the most common cause of pediatric emergency room visits due to a chronic illness.

Some kids have only mild, occasional symptoms or only show symptoms after exercising. Others have severe asthma that, left untreated, can dramatically limit how active they are and cause changes in lung function.
But thanks to new medications and treatment strategies, kids with asthma no longer need to sit on the sidelines, and parents no longer need to worry constantly about their child's well being.
With patient education and the right asthma management plan, families can learn to control symptoms and asthma flare-ups more independently, allowing kids to do just about anything they want.
