Thanks for your query and an elucidated history. Since you are already under a treatment with ATT-meaning anti-tubercular treatment, the medicines like Ethambutol, Rifampicin and isoniazid can cause gastric upset, The pain in the stomach can be intolerance to the medicines and many a time it takes a few days to get accustomed to the new environment caused by these medicines. Laziness can be due to tuberculosis itself. Get liver function tests and an ultrasonography of the abdomen along with standing X-ray of the abdomen. Consult a Physician to discuss these problems. Take liver protective medicines and probiotics. Avoid spicy foods strictly as they are known to alter the bowel habits.
