How long does it take to cure pulmonary tuberculosis?

Pulmonary tuberculosis typically requires one and a half to two years of treatment. The specific duration of treatment for a patient with pulmonary tuberculosis depends on the severity of the disease and the prescribed treatment regimen. In most cases, primary pulmonary tuberculosis can resolve spontaneously. Mild to moderate pulmonary tuberculosis generally does not threaten the patient’s life. However, if the disease is severe and left untreated promptly, it may lead to death.
