The clinical symptoms of normal tuberculosis patients are mainly dry cough, which can be without sputum or accompanied by only a small amount of mucus sputum. There are special clinical cases where the sputum volume of tuberculosis patients is higher: 1. The type of tuberculosis belongs to cavitary tuberculosis with liquefaction and necrosis of lung tissue, and these liquefaction and necrosis are manifested as a large amount of coughing sputum when they are expelled from the body. 2. The combination of tuberculosis with bacterial infection can also be manifested as sputum Increased sputum volume. Patients with tuberculosis do not have to worry about the amount of sputum, and the amount of sputum is not an indicator of the severity and prognosis of tuberculosis, so they should relax and follow the regular anti-tuberculosis treatment once diagnosed. Even patients with heavy dry cough can be relieved after anti-tuberculosis treatment, and if the cough is still heavy, oral cough suppressants can be taken. If sputum is produced during treatment, drink more water to ensure sputum dilution or use sputum dissolvers.
