Weight Loss Surgeries
Congratulations on taking the first step by recognising that you or a close relation has a weight problem and for starting to find out what options there are to help. If you are looking into surgery for weight loss (bariatric surgery) most likely you have made multiple attempts to lose weight, with or without some success, but have not been able to keep the weight off.
Using surgery to assist in weight loss is not a magic bullet. It is part of a comprehensive management plan that involves a team approach. In addition to surgeons, other team members include a dietician, psychologist, your GP, and specialist medical doctors (like a physician) as needed.
What is the role of surgery in weight loss?
Whichever surgical procedure is decided on, it is only one component of a comprehensive weight loss service. The other components essential to successful, sustained weight loss is the type of food you eat, the behaviours around food and the reasons why we eat.
If these other factors are not addressed then there is a significant risk of weight regain in the long term which will negate the long term benefits of surgery.
Types of Surgery
Laparoscopic Sleeve Gastrectomy
This operation transforms the stomach from capacity of approximately 1.5 L to ~ 80ml making it a long tube that connects the oesophagus to the first part of the small bowel (duodenum). The overall effect is to restrict the volume of food that can be eaten at any one sitting.
Roux–En–Y Gastric Bypass
Converts the stomach into a 30ml pouch and then uses small bowel to connect this pouch to the rest of the small bowel further down stream. The over all effect is to restrict the amount of food as well as reduce the amount of calories that are absorbed from that food.
Omega Loop Gastric Bypass
Also converts the stomach into a pouch and then uses small bowel to connect this pouch to the rest of the small bowel further down stream. The over all effect is to restrict the amount of food as well as reduce the amount of calories that are absorbed from that food.
