Mini Gastric By-Pass
The Mini-Gastric Bypass, which is also known as single anastomosis gastric bypass, is a procedure which combines some of the properties of a gastric sleeve and a standard gastric bypass. The upper part of the stomach is divided into a tube, similar to the top three quarters of a sleeve, and then joined to a loop of intestine.
Mini gastric bypass surgery is one of the most commonly performed operations in obesity surgery. The reason or goal for this operation is that diabetes (type 2 diabetes), which is triggered or caused by overweight, is a treatment for diseases such as high cholesterol and blood pressure. It can also be used in patients who have had previous gastric banding or sleeve surgery but have been unsuccessful with weight loss.
The eligibility criteria for Mini gastric bypass surgery is broadly the same as for Roux en y gastric bypass. We consider patients eligible for ‘Mini’ when they have a BMI above 35 with metabolic syndrome.
In our clinic, sleeve gastrectomy operation is recommended to lose weight and control metabolic disorders, but in some cases mini gastric bypass is preferred such as patients whose diabetes cannot be treated with insulin and weight loss.
Are there any disadvantages?
- Complications are similar to gastric bypass surgery. They range in severity from minor to significant. Minor complications include hernias at the surgical site, ulcers, and minor incision infections. Other complications are:
- Malabsorption of vitamins and minerals – Low levels of iron, B12 vitamin and other micronutrients can occur even if recommendations for supplementation are followed.
- Dumping syndrome – Dumping syndrome is a group of signs and symptoms that usually occurs due to poor food choices. It is the result of high sugar foods passing too quickly into the small intestine. Symptoms can include cramping, nausea, dizziness, weakness and fatigue.
Diet After Mini Gastric Bypass Surgery
With your post mini gastric bypass diet you’re going to be building new eating habits but, because you are also recovering from major surgery, you will first need to deal with that. In short, building those new eating habits will be a step by step journey with the first step being to make sure you don’t eat anything that could undermine the healing process. That means for the first 2 weeks you’re going to be on a liquid diet. After 2 weeks you’ll introduce pureed food into your diet. While these will be more substantial than straight up liquids they still need to be smooth, without any solid pieces of food present. After a couple of weeks mixing in unprocessed but soft foods you’ll be ready to try something firmer. At this point you should start eating small portions of regular foods. By the end of the third month your post mini gastric bypass diet should consist mostly of normal foods. That means lean meats, vegetables and whole grains. Refined sugar along with saturated and trans fats should be eliminated from your diet.
