The article discusses the relationship between tuberculosis and diabetes mellitus, highlighting their convergence as global health issues. It reviews the epidemiology of both diseases, their interplay, and the mechanisms by which diabetes increases tuberculosis risk. It also examines how tuberculosis can affect diabetes control and the pharmacological challenges of managing both conditions together. The study shows that diabetes is a significant risk factor for tuberculosis, with higher incidence and severity in diabetic patients. Poor glycaemic control in diabetes is associated with increased tuberculosis risk, and diabetic patients may have atypical radiographic presentations of tuberculosis. The article also explores how tuberculosis can worsen glycaemic control in diabetic patients and how tuberculosis treatment can affect diabetes management. The review emphasizes the need for further research to understand the complex relationship between the two diseases and to develop effective strategies for their management. The study concludes that the increasing overlap of populations at risk for both diseases presents a significant global health challenge.The article discusses the relationship between tuberculosis and diabetes mellitus, highlighting their convergence as global health issues.
