Gastric Bypass Surgery

The gastric bypass has been successfully performed for several decades. It was considered the “gold standard” in bariatric surgery for many of those years because of the exceptional weight loss and disease resolution potential that most patients achieved. Gastric bypass is particularly beneficial for those suffering from type-2 diabetes and GORD (acid reflux/heartburn). In addition, we use micro laparoscopic techniques making the operation nearly scarless.

Gastric bypass results in the size of the stomach being lessened, while a portion of the small intestine is bypassed. This combination offers outstanding disease resolution results with type II diabetes and chronic acid reflux or GORD.


As with most bariatric procedures today, the gastric bypass is performed in a minimally invasive manner, known as a laparoscopic surgery, and takes around 50 minutes to complete with a one-night hospital stay. However, rather than a single, large incision, minimally invasive techniques allow the surgery to be performed through 4 or 5 small incisions in the abdomen. Specially made medical devices are passed through the incisions, including a high-definition camera known as a laparoscope.


How the Gastric Bypass Works

A Doral Health & Wellness surgeon will remove approximately 80% of the existing stomach. What is left is about the size of a golf ball and holds significantly less food. This restriction means that patients will eat considerably less after surgery. The cut-away portion of the stomach is detached but not removed from the abdomen. It receives no food but continues secreting digestive enzymes.


The second half of the procedure is the alteration of the small intestine, also known as the jejunum. At this point, the Doral surgeon will bypass a portion of the small intestine, usually 100cm. This procedure will affect gut hormones and other metabolic functions resulting in fewer calories. As a result, patients who have struggled to lose weight can now finally achieve 25-35% total body weight loss in the 6-12 months after surgery.

Results of the Gastric Bypass

Results will vary between patients as a lifestyle change is an integral part of the success of any bariatric procedure. However, on average, patients willing and able to follow their post-surgical dietary and exercise program may lose up to 35% of their total body weight. In addition to weight loss, many of the diseases associated with morbid obesity, particularly type II diabetes and chronic acid reflux, high blood pressure, high cholesterol, and sleep apnea, are improved or resolved.  

Benefits of Gastric Bypass

· The procedure boasts some of the highest total body weight loss, as well as disease improvement or resolution rates of any weight loss surgery available.

· Particularly high-resolution rates of type II diabetes and chronic acid reflux, also known as gastroesophageal reflux or GORD. Regarding diabetes resolution, we now surmise that the intestinal diversion part of the procedure changes gut hormones, bile acid metabolism and re-balances gut bacteria. These changes lead to improvement or remission of diabetes within the first few days after surgery.

Considerations of the Gastric Bypass

· All of the risks of any major surgical procedure, including pain, blood loss, and infection.

· Patients will have to take vitamin and mineral supplements for the rest of their lives.

· In extremely rare cases, the staple line used to seal the stomach may leak or bleed, requiring an additional surgical procedure.

· Patients may become intoxicated more quickly after surgery.
