My father 67 years old has been diagnosed with renal TB and started with first line of treatment ATT (INH)(RIF)(EMB)(PZA), initially he had several side effects rashes, allergy, breathlessness and fever though post 12 days of treatment today the above side effects are controlled though not resolved completely BUT he has completely lost his appetite and feels nausea even after having respective medicines. He at times skip meals altogether and so as any liquids stating he feels full. He no longer speaks to anyone and prefer to left alone. He isn't sure what exactly he feels. He was better before treatment but only with 12 days into treatment he seems to have too much. How long does this stay when can we expect his appetite will be back? Is his case normal or there is something wrong with protocol made which is ignored? Please advice on same and any guidance or experience will be helpful and also if there is any way to track progress which might boost his stamina to fight?
