What are the clinical manifestations of bronchiectasis? The typical symptoms are chronic cough with large amounts of purulent sputum and repeated hemoptysis. 1. Chronic cough and coughing up large amounts of purulent sputum: about 50-90% of patients have typical coughing and coughing up purulent sputum. In the early stage, the cough can be completely asymptomatic, but with the further development of the disease and co-infection, the cough will be aggravated and the sputum volume will increase, reaching 100-400ml per day with a yellowish green color. 2. Repeated hemoptysis: Hemoptysis can occur repeatedly in varying degrees, from small amounts of blood in sputum to large amounts of hemoptysis, and the amount of hemoptysis can reach hundreds or even thousands of milliliters, and the amount of hemoptysis is not necessarily proportional to the extent and degree of the lesion. In some patients, hemoptysis is the main symptom, but coughing and sputum are not obvious, and this type is called “dry bronchiectasis”. 3.Fever: If repeated secondary infections, poor bronchial drainage, sputum is not easy to cough up, you can feel chest discomfort and inflammation extends to the lung tissue around the lesion, and symptoms such as high fever, poor sweating, emaciation and anemia appear. 4, other symptoms: with the aggravation of the disease, patients have a loss of appetite, wasting, etc.. Children can cause growth and malnutrition, and a few patients can have secondary amyloidosis. In addition, early bronchial patients may have no obvious signs, and when the lesion is obvious, persistent wet rales may be heard at the lesion site, and the rales may disappear temporarily after sputum discharge. Pestle-shaped fingers (toes) may appear in about 1/3 of patients with long-standing disease.
