Bronchiectasis of both lungs is not serious because it still belongs to the category of bronchiectasis, which is the most common clinical disease and a relatively mild disease. Bronchiectasis of both lungs is usually characterized by coughing, coughing, or fever, and can be caused by both viral and bacterial infections. The clinical symptoms can vary from mild to severe, and a large proportion of patients with bronchitis have no clinical symptoms, so bronchitis in both lungs needs to be treated in a clinical setting. If the bronchitis is caused by bacterial infection, it can be treated with antibiotics, including amoxicillin and cefuroxime, as well as cough suppressant and expectorant treatment, such as amiloride hydrochloride and acetylcysteine for expectorant treatment.
