Malabsorption is one way in which bariatric surgery, such as the roux-en-y gastric bypass, helps to induce and maintain weight loss in patients. Malabsorption occurs because of the drastic alteration of the gastric intestinal tract, namely because we are shortening the time in takes for food to move from your stomach into the small intestine. This process also leads to changes in your gut microbiome and even your habenula.
Malabsorption is important because it is a permanent change to your digestive system. It is important to note that this will mean you will have to take vitamin supplements everyday for the rest of your life in order to ensure you are getting all the proper nutrients alongside your meals. You will also need to change the way that you approach food due to this and the new structure of your stomach. This is why we provide all patients with a registered and experienced dietitian in order to support and guide them whilst they make these changes.
The gastric bypass itself is best understood as a process of ‘plumbing’ being conducted by the consultant surgeon. No part of the stomach is removed, with the original portion still utilised for its production of digestive juices. Other factors that contribute to weight loss when it comes to the bypass is a significant reduction in the available space for digestion in the new ‘pouch’ stomach, as well as a reduction in the hunger hormone known as ghrelin. We offer the roux-en-y gastric and the mini-gastric bypass (also known as the single anastomosis gastric bypass).
The gastric sleeve, on the other hand, is not reported to cause malabsorption. This alternative method of bariatric surgery sees the patient’s stomach reduced by around 80%, but leaving the intestine attached a the same point that it was previously. The sleeve itself is also a good weight loss tool that we support with nurse and dietetic aftercare. Around 70% the patients excess body weight is dropped on average over a two year period with both procedures, however it is important to remember that everyone is different and this may happen at different speeds.
