Bronchiectasis exhibits many symptoms, but the most common are chronic cough and sputum production. The amount of sputum in bronchiectasis can vary greatly from person to person, and to some extent, it can reflect the severity of the condition. Some patients may have significant coughing and sputum production, with sputum amounts reaching over one hundred milliliters per day. In others, the condition may be more stable, with only a few milliliters of sputum per day. Additionally, patients with bronchiectasis may experience hemoptysis, which often recurs and can manifest as blood-streaked sputum, minor bleeding, or sudden severe bleeding. Significant bleeding can be particularly dangerous, potentially leading to death within minutes. Bronchiectasis can also cause recurrent lung infections and chronic long-term infection, which may be accompanied by fever, fatigue, loss of appetite, weight loss, anemia, and other symptoms.
