The treatment time of complicated diseases is relatively long, and it depends on the drug resistance of tuberculosis. During the treatment, you must cooperate with the treating doctor and take the medicine according to the doctor's advice. If the effect is good in the later stage of treatment, physical exercise can be carried out, but the intensity should be controlled, not too much. As for losing weight, you should consult a doctor according to your own situation after recovery. In fact, people with tuberculosis are generally not too fat. Tuberculosis consumes a lot of nutrients in the human body, and it is generally difficult to gain weight.
