1, fever Repeated infections in patients with bronchiectasis can cause systemic toxic symptoms. Early fever may not be present, but when poor drainage of secretions and inflammation spreads, causing pneumonia, lung abscess, pleurisy or abscess chest, the patient may have high fever. 2, repeated hemoptysis Bronchiectasis hemoptysis accounts for about 50-75%, the amount of hemoptysis varies, from blood in the sputum to hemoptysis, often due to the rupture of small bronchial arteries with high pressure, blood can be ejected rapidly, the bleeding volume can reach hundreds or even thousands of milliliters, after the bleeding vascular pressure is reduced and contraction, bleeding can automatically stop. The amount of hemoptysis is not necessarily proportional to the extent and degree of the lesion. Some patients have hemoptysis as the main symptom, but cough and sputum are not obvious, and the general condition of the patient is good. 3. Chronic cough and coughing up large amounts of purulent sputum About 50-90% of patients have a typical cough 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, up to 100-400ml per day, with a yellowish green color, and when the position is changed, the secretions will come into contact with the normal mucous membrane, causing the cough to reverse and a large amount of purulent sputum to be coughed out. 4.Other symptoms With the aggravation of the disease, patients have loss of appetite, wasting, etc.. Children may cause growth and malnutrition, and a few patients may have secondary amyloidosis. 5.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. About 1/3 of patients with prolonged disease may have pestle-like fingers (toes).
