Chronic bronchitis is a much more serious condition and while it can be a progression from acute bronchitis it can develop on its own from being exposed to lung irritants in the environment. The number one and number two irritant is cigarette smoke, first and second hand respectively.
The most effective treatment for chronic bronchitis is to stop toxic exposure. If you smoke and notice that you have a daily productive cough be aware that you may already have or are on your way to developing chronic bronchitis. Don’t ignore this symptom. It’s serious. Seek medical attention and help in quitting smoking.
But what if you have a daily productive cough and you don’t smoke nor are you regularly exposed to cigarette smoke? You could still have chronic bronchitis. There are numerous chemical toxins that may cause chronic bronchitis. People who are routinely exposed to dust and fumes in the workplace are also at risk. If your doctor diagnoses chronic bronchitis then do whatever you can to eliminate your exposure to these pollutants.
