Chronic Bronchitis, a long-term condition characterized by persistent cough and mucus production, can significantly impact your quality of life. While the exact cause isn't always clear, several factors play a major role in its development. The primary culprit behind chronic bronchitis is cigarette smoking. The harsh chemicals in cigarettes irritate and damage the lining of your bronchial tubes, leading to inflammation and excessive mucus production. Over time, this damage can become permanent, hindering your airways' ability to clear mucus effectively. Exposure to secondhand smoke can also contribute to chronic bronchitis, even for non-smokers.
