Bronchiectasis (say “brawn-kee-ECK-tuh-sus”) is a lung problem in which the breathing tubes are stretched and become larger. The buildup of mucus causes the stretching and can lead to swelling and infections. You may find it harder to breathe and cough up mucus out of your lungs. Some people are born with it. Other people get it because of another health problem, usually cystic fibrosis or a lung infection such as pneumonia or tuberculosis.
Symptoms are often different for everyone. But a cough that brings up mucus, or sputum, is common. The condition is usually treated with antibiotics, medicines to relax the airways (bronchodilators), and medicines to make it easier to cough up mucus (expectorants).
