Diabetes mellitus patients are usually at high risk of developing tuberculosis, the immune dysfunction caused by long-term high blood sugar, which can increase the susceptibility to tuberculosis. Severe tuberculosis could accelerate the course of diabetes mellitus and pose great difficulty to the clinical treatment.
