Chronic Bronchitis

Chronic bronchitis is one of several chronic obstructive lung diseases that manifests as a regular cough seen most days of the year for at least two years in a row. The principle risk factor for developing chronic bronchitis is a strong smoking history, though occasionally occupational exposures predispose patients to chronic bronchitis. In additional to cough with increased production of phlegm, patients with chronic bronchitis may also notice breathlessness, wheezing, chest tightness, and swelling of the lower extremities. Symptoms tend to flare in the setting of upper respiratory infections and other triggers. The diagnosis is usually established by a physician who obtains the proper history of longstanding cough and may be further supported by other tests such as chest x-rays and pulmonary function testing. Management involves smoking cessation and regular use of bronchodilators and other pulmonary medications. Certain patients with chronic bronchitis may benefit from home oxygen therapy.
