Background: This study was conducted to assess the Prevalence of tuberculosis in diabetic subjects. Material and methods: Patients with chest conditions who visited the hospital's outpatient clinic were surveyed to determine the incidence of tuberculosis, TB in conjunction with diabetes, and antituberculosis drug resistance. The hospital's records were examined carefully, and the information was entered into an Excel spreadsheet. Results: In this study, there were total 100 subjects having tuberculosis and diabetes mellitus out of which 50 were males and 50 were females. Majority of the subjects belonged to the age group of 41-60 years. Out of 500 subjects attending the hospital, only a 100 of then had tuberculosis and diabetes mellitus. Hence, the prevalence of the condition was found to be 20%. Conclusion: The prevalence of tuberculosis with diabetes mellitus was 20%. Knowledge of the reciprocal relationship between communicable and noncommunicable diseases can encourage primary care doctors to effectively manage both, and increased screening and treatment efforts can further reduce prevalence in a community.
