Obesity and type 2 diabetes mellitus (T2DM) are major public health issues globally over the past few decades. Despite dietary interventions, lifestyle modifications and the availability of several pharmaceutical agents, management of T2DM with obesity is a major challenge to clinicians. Metabolic surgery is emerging as a promising treatment option for the management of T2DM in the obese population in recent years. Several observational studies and a few randomised controlled trials have shown clear benefits of various bariatric procedures in obese individuals in terms of improvement or remission of T2DM and multiple other health benefits such as improvement of hypertension, obstructive sleep apnoea, osteoarthritis and non-alcoholic fatty liver disease. Uncertainties about the long-term implications of metabolic surgery such as relapse of T2DM after initial remission, nutritional and psychosocial complications and the optimal body mass index for different ethnic groups exist. The article discusses the major paradigm shift in recent years in the management of T2DM after the introduction of metabolic surgery.
Core tip: Metabolic surgery or bariatric surgery has revolutionised the 21st century management of type 2 diabetes mellitus (T2DM) in obese patients. Marked reduction of body weight following the bariatric procedures results in improvement or remission of T2DM in a significant number of patients along with improvement of other diseases associated with obesity such as hypertension, obstructive sleep apnoea, osteoarthritis and non-alcoholic fatty liver disease. Uncertainty exists about the long-term outcomes in terms of diabetes relapse, nutritional and psychosocial complications. However, the marked benefits of metabolic surgery outweigh the risks related to the procedure that has resulted in a major paradigm shift in the management of obese population with T2DM in recent years which is the topic of discussion of this paper.
