Depression in type 2 diabetes mellitus—A brief review

Diabetes mellitus is a chronic disease which has been associated with depression. Depression is more common in adults with type 2 diabetes mellitus (T2DM) as compared to those without. Both micro- and macro vascular diabetic complications are associated with depression and have shown to increase the risk of mood disorder. Further, poor glycemic control in T2DM patients could lead to more complications of diabetes and such patients are more likely to develop depression. More research is needed in this area to determine the exact relationship between depression and T2DM and to unfold the mystery of mechanism behind this.
