Abstract

Massive obesity results in serious diseases. Surgery has frequently been the only means to achieve and sustain significant weight loss and resolve co-morbidities. Thus, operations providing weight loss by gastric restriction with early satiety and especially by intestinal bypass with controlled malabsorption have evolved over the past 50 years. A brief history of bariatric operations is given, including their major complications, management and potential nutritional sequelae. The bypass operations are now being used to resolve diabetes mellitus type-2 in patients with lesser obesity. Oral supplementation is necessary postoperatively for vitamin D3, calcium, iron, B12 and folate. Currently, the MGB and OAGB are being performed, which are fairly rapid and simple with excellent resolution of co-morbidities, durable weight loss and ease of reversal.
