About Gastric Bypass

Gastric bypass involves creating a very small pouch (about 1 ounce) from the upper part of the stomach, and making a small connection (less than 1/2 inch diameter) between the stomach pouch and the intestine. The gastric bypass operation is done laparoscopically, typically through 5 small incisions.

Hospital stay after surgery is usually 1-2 days. Recovery is generally rapid because of the minimally invasive laparoscopic approach. Patients typically return to work after 2-3 weeks.

Gastric Bypass Weight Loss

Gastric bypass typically results in excellent weight loss – the better studies report an average of 70-80% excess weight loss after surgery. Long-term studies (10+ years) show that patients, on average, maintain the majority of their initial weight loss over time.*
More about gastric bypass weight loss

Gastric bypass causes weight loss by restricting food intake and by altering the biology of weight regulation by resetting the body weight “set-point” to a lower weight.*

Resetting the body weight set-point to a lower weight is the key to why gastric bypass works as well as it does. This is what makes long-term maintenance of weight loss possible after surgery. Because nonsurgical weight loss methods don’t change the body weight set-point, long-term maintenance of weight loss after diet and exercise programs is virtually impossible.*

Why Gastric Bypass Surgery?

Patients most frequently favor sleeve gastrectomy over gastric bypass. Advantages of sleeve gastrectomy include less long-term risk, and a more normal experience of eating.

In certain situations, however, gastric bypass is considered a good, or better, choice.

Diabetes
Gastric bypass is better for diabetes. Studies show that gastric bypass induces remission of diabetes (i.e. normal blood sugar without medication) in up to 80% of patients. Usually patients can discontinue their diabetes medications immediately after surgery.

Chronic GERD
Gastric bypass resolves gastro-esophageal reflux disease (GERD) in almost all patients. Sleeve gastrectomy can make GERD worse in certain situations. In cases of long-standing chronic GERD or hiatal hernia, gastric bypass may be a better choice.

High BMI
Many surgeons favor gastric bypass for patients with a body mass index (BMI) of greater than 50 because studies suggest that BMI > 50 patients typically lose more weight with gastric bypass than with sleeve gastrectomy.

More Established
Gastric bypass is considered by many surgeons to be the “gold-standard” operation for weight loss, because it is the most established (>40 years) and best studied of the weight loss operations.

Gastric Bypass Orange County – Am I a Candidate?

Gastric bypass Orange County candidates are generally at least 75-100 pounds overweight (BMI 35 or greater), and have tried and failed to lose weight and keep it off. Insurance companies generally require patients in the BMI 35-40 range to have other medical problems, such as diabetes, high blood pressure, or sleep apnea.

Good gastric bypass candidates also understand that surgery is a tool to help with weight loss, not a cure for obesity. Good candidates understand the necessary changes they need to make in their eating/exercise habits after surgery, and are willing/capable of making these changes.

What are the Risks?

Potential early postoperative complications after gastric bypass include blood clots and leaks. The risk for blood clots and leaks can be minimized with quality surgery and good patient care, but not completely eliminated. Potential long-term risks include nutritional deficiencies, bowel obstructions, and ulcers.
