Explain Gastric Bypass - surgical management for obesity?
Surgery is the current 'gold standard' for bariatric surgical procedures. It involves use of a stapling device to create a tiny stomach 'pouch' by partitioning the stomach near its upper end to reduce the capacity of the stomach. On an average, the patient loses 30-40% of weight by this procedure. The stomach size can also be reduced by using stainless steel staples across the upper portion of the stomach. Only about 1 cm opening is left into the distal stomach. This method is known as gastroplasty. This is found to be quite successful.
