Gastric bypass is a type of weight loss surgery. It is done to help one reduce their food intake if they have tried all means to lose weight, but they haven’t worked. This type of surgery has made people improve their life’s quality. This is because they have lower risks of developing diseases associated with being overweight. This is how gastric sleeve for weight loss works
How it is done
It is a complex surgery which is performed under general anesthesia. The gastric sleeve surgery takes between one and four hours. The patient then stays in the hospital for up to seven days post- surgery. The two types of techniques used include the traditional and laparoscopic technique and the biliopancreatic diversion by pass.
The traditional and laparoscopic
This is the least complicated technique than the other biliopancreatic diversion technique. This is because the portions of the stomach are not removed. The traditional surgery is usually an open one with a long incision.
The laparoscopic surgery involves making many small incisions and inserting the laparoscopic tool which provides a visual of the stomach during the surgery. The main advantage is that there is less scarring when compared to the traditional surgery hence faster recovery. However, being a new technique, it is still under observation to know what its effects are.
Biliopancreatic diversion bypass
This is also an open surgery which involves using a long incision which eventually forms a permanent scar. The portions of the stomach are removed, and the bypass is then attached to the distal ileum. It has more risks due to the nutritional deficiencies that may arise as a result.
For both techniques, a portion of the stomach is stapled and a small pouch created to help reduce one’s food intake. The part of the small intestine affected is then attached to the pouch created making food bypass the duodenum. Additional bypasses of the small intestine are formed, so that food absorption is reduced. As a result, food intake is reduced and so is hunger hence promotes healthy weight loss. Results are seen after a year, and by the end of the second year, greater significance is seen.
Patients are usually admitted one or two days before the surgery and up to seven days after the surgery. One will need at least two weeks and a maximum of five weeks before resuming normal activities. The abdomen may be swollen, and one may feel a certain discomfort. Medicines can be prescribed to manage this.
After care treatment
One will adopt a dietary plan, be involved in regular exercising, and take vitamin supplements as well as behavioral modification. One may have to get their dietician and a trainer for an extended period to help them with full recovery. Plastic surgery may be necessary to help get rid of the loose skin.
Some of the risks include bowel obstruction, leakage from the staple or the suture lines and anesthesia complications. Long term risks include weight regain and nutritional deficiencies. There are also risks of developing psychological problems…
