Hello Dear. First and foremost thing right now is that you need to take the treatment as suggested by your doctor without fail. Second thing you can t always prevent acute or chronic bronchitis. However, you can take steps to lower your risk for both conditions. The most important step is to quit smoking or not start smoking. Also, try to avoid other lung irritants, such as secondhand smoke, dust, fumes, vapors, and air pollution. For example, wear a mask over your mouth and nose when you use paint, paint remover, varnish, or other substances with strong fumes. This will help protect your lungs. Wash your hands often to limit your exposure to germs and bacteria. Your doctor also may advise you to get a yearly flu shot and a pneumonia vaccine. Good control of asthma may prevent chronic bronchitis from developing. However the genetic predisposition to chronic bronchitis is not currently preventable. Also, try to stay away from people who have colds or the flu. See your doctor right away if you have signs or symptoms of a cold or the flu. Follow a healthy diet and be as physically active as you can. A healthy diet includes a variety of fruits, vegetables, and whole grains. It also includes lean meats, poultry, fish, and fat-free or low-fat milk or milk products. A healthy diet also is low in saturated fat, trans fat, cholesterol, sodium (salt), and added sugar. If you have chronic bronchitis, you may benefit from pulmonary rehabilitation (PR). PR is a broad program that helps improve the well-being of people who have chronic (ongoing) breathing problems. People who have chronic bronchitis often breathe fast. Talk with your doctor about a breathing method called pursed-lip breathing. This method decreases how often you take breaths, and it helps keep your airways open longer. This allows more air to flow in and out of your lungs so you can be more physically active. To do pursed-lip breathing, you breathe in through your nostrils. Then you slowly breathe out through slightly pursed lips, as if you re blowing out a candle. You exhale two to three times longer than you inhale. Some people find it helpful to count to two while inhaling and to four or six while exhaling. Hope i have answered your question. Feel free to contact me if you have any more questions. I ll be glad to help you. All the best With warm regards Dr Sanjay Kini
