HI. Thanks for your query. Diabetes has to be well under control for the effectiveness of any antibacterial treatment including that of Tuberculosis. The treatment was correct in the initial phase. After the relapse you may need a second line of treatment under the guidance and observation of a Physician. This is important as the same drugs may not be effective when there is relapse. Secondly, you need to have a proper diagnosis done by Laparoascopy and confirm whether there is relapse or aftereffect / sequel or complication of TB. This is the most important aspect.
