Chronic bronchitis often presents with symptoms of coughing, which are long-term, recurrent, and progressively worsen. Coughing is a very prominent manifestation of this condition. For mild cases, symptoms typically flare up during the winter and spring seasons, especially noticeable upon waking in the morning, with less coughing during the day. In the summer and fall, the coughing may lessen or disappear. In severe cases, patients may experience coughing throughout the year. It's crucial to take note and, under a doctor's guidance, use corresponding anti-inflammatory and anti-infection medications, along with cough suppressants and expectorants to alleviate symptoms. Another characteristic is the presence of phlegm, typically white mucous sputum or serous foamy sputum. It's advised to use expectorants for treatment. During treatment, avoid smoking and alcohol, and maintain a light diet. Additionally, if there are symptoms of asthma or wheezing, it may be necessary to take medications to alleviate these symptoms.
