Impact of surgical and nonsurgical weight loss on diabetes resolution and cardiovascular risk reduction.

Weight loss favorably modifies most cardiovascular risk factors, in particular the diagnostic criteria for metabolic syndrome, type 2 diabetes mellitus, and hypertension. Treating the spectrum of diabetes by promoting disease control or resolution invariably improves cardiovascular outcomes. However, in clinical trials and routine medical practice, long-term weight loss has been difficult to achieve due to wavering patient motivation, inadequate resources, ineffective medical treatments, lack of psychosocial support, recidivism, or combinations thereof. The issue is not information but rather methods, motivation, and behavioral changes. This article reviews surgical and nonsurgical methods of weight loss and their impact on cardiovascular risk factors, especially the resolution of type 2 diabetes mellitus, and the implications for cardiovascular event reduction in patients with morbid obesity.
