Bronchitis is a condition that causes the lining of your bronchial tubes to become inflamed. The tubes are responsible for carrying air into and out of your lungs, so when they become inflamed you may notice that you have trouble breathing. Bronchitis is usually caused by viruses, but in the case of chronic bronchitis, it can be caused by cigarette smoking, dust, or air pollution. People who suffer from other acute illnesses such as colds or immune system diseases are at a higher risk for it. The following is a quick look at the most common symptoms of bronchitis.
The number one symptom of bronchitis is a constant cough. Sometimes the cough will cause you to bring up mucus, but sometimes it is non-productive. Any cough that lasts over three weeks can be an indicator of bronchitis or other more serious conditions, so it is a good idea to get checked out by your medical practitioner.
