Core Tip

Core Tip: The ambit of metabolic surgery for diabetes has increased. Individuals with inadequate glycemic control can be considered for surgery if less severely obese, and even more so if they are of Asian origin. However, both diabetes and obesity are associated with multiple comorbidities that require optimization before surgery. There are several clinical guidelines for the preoperative management of individuals with obesity; however, specific suggestions addressing these concerns in persons with diabetes have not been recommended. It is important to achieve optimal glycemic control and diagnose and manage cardiovascular, pulmonary, gastrointestinal, and renal complications before surgery. Nutritional assessment, psychological evaluation, and ruling out specific endocrine disorders are other essential adjuncts. These guidelines will help to standardize the management of preoperative comorbidities and improve postoperative outcomes in individuals with diabetes who opt for metabolic surgery.
