Abstract

Obesity and type 2 diabetes mellitus (T2DM) are currently two pan-endemic health problems worldwide and are associated with considerable increase in morbidity and mortality. Both diseases are closely related and very difficult to control by current medical treatment, including diet, drug therapy and behavioral modification. Bariatric surgery has proven successful in treating not just obesity but also in significantly decreasing overall obesity-associated morbidities as well as improving quality of life in severely obese patients (body mass index [BMI] >35 kg/m2). A rapid increase in bariatric surgery started in the 2000s when the laparoscopic surgical technique was introduced into this field. Many new procedures had been developed and changed the face of modern bariatric surgery. Recently, bariatric surgery played as gastrointestinal metabolic surgery has been proposed as a new treatment modality for obesity-related T2DM for patients with BMI >35 kg/m2. Strong evidence has demonstrated that bariatric/metabolic surgery is an effective and durable treatment for obese T2DM patients. Bariatric/metabolic surgery is now becoming an important surgical division. The present article examines and discusses recent advancements in bariatric/metabolic surgery and covers four major fields: (i) the rapid increase in numbers and better safety; (ii) new procedures with better outcomes; (iii) from bariatric to metabolic surgery; and (iv) understanding the mechanisms and personalized treatment.

Keywords: bariatric surgery; metabolic surgery; severe obesity; type 2 diabetes.
