Tuberculosis can kill. Tuberculosis is mainly transmitted through the respiratory tract. After infection, the patient’s resistance will be lowered, and in severe cases, it will be accompanied by organ failure, lung destruction, tuberculosis hemoptysis, and other symptoms, which will make people die. 1. Organ failure: Due to the slow and long treatment process of tuberculosis, the patient’s resistance decreases, which may cause different degrees of damage to the liver and kidney functions, and the risk of secondary infections and mixed infections will be greatly increased. If the infection worsens, it will then lead to organ failure and kill the person. 2. Lung destruction: if the patient’s lesion infection area is large, coupled with the continuous deterioration of the condition, it will eventually lead to lung destruction, lung destruction patients, due to severe malnutrition, repeated lung infections, the probability of survival is extremely low, it will make people die. 3. Tuberculosis hemoptysis: Tuberculosis foci invade blood vessels, triggering bronchial dilatation, followed by hemoptysis, sputum, blood clots will block the airways, causing asphyxiation, which will cause death. Tuberculosis patients are recommended to go to the hospital in time, improve the examination to clarify the cause of the disease, under the guidance of the doctor to give targeted treatment or treatment.
