thank you for your question
i have read your problem and i would like to tell you that fever in case of tuberculosis
fever may persist for about 2months on therapy. sometimes it can be due to systemic response for which steroids
is usually benefecial, so i would advice you to take prednisolone
for a fortnight. considering your weight loss
i would recommend you a colonoscopic biopsy
to confirm the diagnosis. continue your anti tubercular therapy with 2months of intensive phase and 4months of continuation phase.
kindly revert us back with the biopsy report so that we can advice you for further plan of treatment.
wish you a good health and success
