AbstractThe prevalence of morbid obesity in the UK population is rising, bringing with it increased levels of cardiovascular disease, diabetes, arthritis and early mortality. The overall cost to the health service is high, and is set to increase over the coming decades as the overweight population ages. Dietary, lifestyle and pharmacological interventions offer at best reasonable, short-term weight reduction and often fail. Surgical intervention is a safe and effective means of delivering marked long-term weight reduction. This article compares and contrasts the options available for surgical treatment of morbid obesity based on a review of the current literature.
