Asthma: Dr. Pat Herlihy

J. Patrick Herlihy
"What You Need to Know About Your Lungs"
Pulmonary/Critical Care and Sleep Medicine

Dr. Pat Herlihy, a lung specialists in Houston, Texas, will be joining Dr. Galati this week on Your Health First to discuss current issues related to lung disease. There are numerous symptoms that could represent a problem with the lungs, but the consumer needs to keep in mind that there are other causes, besides lung diseas, that can cause symptoms.

Asthma (Az-muh) is a chronic disease that affects your airways. The airways are the tubes that carry air in and out of your lungs. If you have asthma, the inside walls of your airways are inflamed (swollen). The inflammation (IN-fla-MAY-shun) makes the airways very sensitive, and they tend to react strongly to things that you are allergic to or find irritating. When the airways react, they get narrower, and less air flows through to your lung tissue. This causes symptoms like wheezing (a whistling sound when you breathe), coughing, chest tightness, and trouble breathing, especially at night and in the early morning.

Asthma cannot be cured, but most people with asthma can control it so that they have few and infrequent symptoms and can live active lives.

When your asthma symptoms become worse than usual, it is called an asthma episode or attack. During an asthma attack, muscles around the airways tighten up, making the airways narrower so less air flows through. Inflammation increases, and the airways become more swollen and even narrower. Cells in the airways may also make more mucus than usual. This extra mucus also narrows the airways. These changes make it harder to breathe.
