Hi ! Good evening. I am Dr Shareef answering your query. If I were her doctor, I would advise a liver function test for her, as teh ATT could affect the liver function. As such the tubercular infection would cause anorexia, which would gradually be alright once the ATT starts having its effect, which might take some time. Please see that she gets proper diet consisting of high protein and fresh fruits. You could add a proton pump inhibitor drug to her medicines and also a probiotic. If medically fit, it would be wise to encourage her for some regular light exercise like a morning or evening walk. I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing health care magic to clear doubts on your health problems. Wishing you an early recovery. Dr Shareef.
