Anxiety disorders in adults with diabetes mellitus.

Anxiety disorders are common among patients with diabetes and appear to recur in a substantial proportion of cases. The presence of generalized anxiety disorder is associated with both poorer glucose control and the increased report of clinical symptoms of diabetes. A complex interactive model best accommodates observations from psychiatric-diabetic research, one wherein diabetes may affect psychiatric status or vice versa in an independent or reciprocal fashion. No information from systematic studies is available currently to determine if treatment of the psychiatric disorder will have a beneficial impact on glucose regulation, despite the direct clinical relevance of such information to management of diabetes.
