For patients with no obvious changes in nodules after 9 months of tuberculosis treatment, if the symptoms of the disease have disappeared, the indicators are normal, and multiple Mycobacterium tuberculosis tests are negative, it is sufficient to do a good job of regular review. If the respiratory symptoms (e.g. cough, dyspnea, etc.) and systemic symptoms (e.g. night sweats, fatigue, persistent afternoon fever, etc.) have disappeared after 9 months of anti-tuberculosis treatment, the exudative lesions of the patient have basically been absorbed on the imaging examination, the repeated tests for Mycobacterium tuberculosis have been negative, and the other indexes (e.g. blood counts, sedimentation rate, etc.) have returned to normal, then it will be enough to do the regular checkups. For patients infected with tuberculosis, if the condition is more serious, even if they are cured, there are nodules and fibrous foci left, but it does not have a great impact on the health of the body. If diagnosed with tuberculosis, it is recommended to seek early medical attention and standardized treatment in order to reduce the adverse effects of the disease.
