Don't needlessly suffer with a barking cough! Treatments for chronic bronchitis are now available to help slow the progression of the condition, prevent additional complications, and relieve symptoms. Bronchitis develops when there is irritation or inflammation of the bronchial tubes, which carry air to and from the lungs. When these airways get irritated, thick mucus forms and plugs up the tubes, causing a tightness in the chest, trouble breathing, and coughing that produces mucus. To be considered chronic, the resulting coughing lasts longer than three months. The top three treatments for chronic bronchitis include bronchodilators, oxygen therapy, and pulmonary rehabilitation.
