If you've reached the point where you want to find out more about Gastric bypass surgery, then you're already on the right path. Being a well-informed patient is the best way you can help yourself achieve your weight loss goals. Below is more information about the human digestive system and gastric bypass. Most gastric bypasses are performed laparoscopically, even in patients who have had previous open surgery. An animated video is included on this page to show the surgery process of Gastric Bypass.
Roux-en-Y gastric bypass surgery uses a combination of restriction and malabsorption. During the procedure, our surgeons create a small stomach pouch, about the size of an egg. The bowel downstream in then divided and connected to the small stomach pouch. The other end is reinserted further down, thus bypassing the remainder of the stomach and a portion of the small bowel. This allows food to bypass a large portion of the small intestine, and thus allows less to be absorbed. Having the smaller stomach pouch causes patients to feel fuller sooner and eat less food.
Excess Weight Loss
Gastric bypass patients typically lost 61.6 percent of their excess weight.
Studies found that gastric bypass:
- Resolved type 2 diabetes in 83.8% of patients and often resolved the disease within days of surgery
- Resolved high blood pressure in 75.4% of patients
- Improved high cholesterol in 95% of patients
- The American Diabetes Association (ADA) has recognized gastric bypass surgery as a treatment of diabetes.
Quality of Life
One meta-analysis stated that for bariatric surgery patients who experienced significant weight loss:
- Overall quality of life improved greatly.
- They experienced improved physical functioning and appearance.
- They experienced improved social and economic opportunities.
One study found that gastric bypass patients were able to:
- Leave the hospital after two days
- Return to work after 21 days
Potential Concerns of Gastric Bypass
- A condition known as dumping syndrome can occur from eating high-fat, high-sugar foods. While it isn’t considered a health risk, the results can be very unpleasant and may include vomiting, nausea, weakness, sweating, faintness, and diarrhea.
- Dumping is almost always controlled with the diet.
- Patients must supplement their diet with a daily multivitamin and calcium. Some patients must take vitamin B12 and/or iron.
- The stomach, duodenum, and parts of the small intestine cannot be seen easily using X-ray or endoscopy if there are problems after surgery such as ulcers, bleeding, or malignancy.
