Hello
You  didn't mention you are a male or female because in 
GENITOURINARY TUBERCULOSIS , this is very important .
But any how , standard ANTITUBERCULOSIS 
CHEMOTHERAPY is indicated for genital T B , although some prefer prolonged therapy . 
As you mentioned that you took R 
cinex for 3 months and later on etambutal ( mycobutol ) , ctogen ( supplement ) and solonex ( isonex ) for another one month and advised for another 2 month.
At this stage I recommend you please consult a tuberculosis specialist and get his opinion about standard treatment and duration of treatment . 
If genital TB left untreated may result in obstructive nephropathy, recurrent bacterial infections .
As far as concerned about obesity and 
diet plan , I  recommend you take HIGH protein diet , regular exercise , healthy diet as these will improve general condition.
Hope this will help you.
