About Gastric Bypass Surgery

The gastric bypass operation involves creating a very small pouch (about 1 ounce) from the upper part of the stomach, and making a small connection between the stomach pouch and the intestine. The gastric bypass operation is done laparoscopically, generally using 5 small incisions. Patients typically stay in the hospital for 1-2 days, and return to work in 2-3 weeks.

The gastric bypass operation causes weight loss by restricting food intake, and by changing the biology that regulates bodyweight. This biology change results in the body accepting a lower weight without trying (biologically) to achieve weight regain.*

This biology change is what makes long-term weight loss possible after surgery.* The reason nonsurgical weight loss methods don’t work long-term is because nonsurgical weight loss methods don’t change this weight regulation biology.

Why Gastric Bypass?

Although the sleeve gastrectomy operation gets the most attention and interest these days, the gastric bypass operation remains a worthy option, with several distinct strengths.

The biggest strength of the gastric bypass operation is that it has successfully withstood the test of time. Many weight loss operations have come and gone over the years, most recently gastric banding, but the gastric bypass operation is still going strong after more than 40 years. Why? Because history (the most difficult judge of all) has proven the gastric bypass operation to be effective and safe.*

Other strengths of the gastric bypass operation include: 1) gastric bypass is a better treatment for diabetes than gastric sleeve, 2) gastric bypass is better for gerd (gastroesophageal reflux disease) than gastric sleeve, 3) gastric bypass results in better long-term weight loss than gastric sleeve (probably), and 4) gastric bypass results in more weight loss in heavier patients (BMI>50) than gastric sleeve (probably).*

The disadvantage of the gastric bypass operation is that it is more invasive and therefore higher risk than the gastric sleeve operation. The above gastric bypass benefits, however, are generally felt to outweigh this disadvantage in certain groups of patients: those with diabetes, those with severe/chronic gerd or large/chronic hiatal hernia, and those with higher initial BMI.

Gastric Bypass Outcomes

The gastric bypass operation has been proven over 40+ years to be a safe and effective operation for weight loss – the better published studies report an average of 70-80% excess weight loss after surgery.* Long-term studies (10+ years) show that patients maintain the majority of their weight loss over time.*

The published studies, however, do show significant variation in outcomes between different surgeons and programs. Some surgeons and programs achieve much better weight loss results and much lower complication rates than other surgeons and programs.*

The reason for this variation is because gastric bypass surgery is not a standardized product. It is a service that encompasses the performance and details of the operation (e.g. pouch size, pouch/intestine connection size, quality of technique, etc.), and patient care before/after surgery (education, follow-up, support). Quality of service varies, and this greatly affects patient outcomes.

Dr. Oliak and his Orange County gastric bypass program prioritize high-quality surgery and patient care, and have an established record of achieving excellent, industry-leading patient outcomes.*

Gastric Bypass Surgery and Recovery

The gastric bypass operation involves constructing a very small pouch (about 1 ounce volume) from the upper part of the stomach, and making a small connection (about 1/2 inch diameter) between the stomach pouch and the intestine. When food is eaten, it passes through the small stomach pouch into the intestine, and bypasses the majority of the stomach.

The gastric sleeve bypass operation is done laparoscopically, generally using 5 small incisions. The operation typically takes 1.5-2 hours to complete. Patients generally stay in the hospital for 1-2 days, and return to work in 1-3 weeks. Recovery is usually rapid because of the minimally invasive, laparoscopic approach.

Patients remain on a liquid diet for 2-3 weeks after surgery, and then slowly transition onto solid foods. Meal portion sizes are typically 2-4 ounces when patients start solid food, and slowly increase in size to approximately 6-8 ounces over the first 1 year.

Gastric Bypass Changes Bodyweight “Set-Point”

Gastric bypass causes weight loss by restricting food intake and by changing the body weight ”set-point” to a lower weight.

Everybody has a “set-point” weight. This is the weight that the body tries to maintain. When a person loses weight to below the set-point, the body responds by increasing hunger, appetite, and cravings, and by decreasing metabolism in an effort to cause weight regain back up to the set-point weight. This biology is what makes losing weight so difficult.
Body weight set-point blocks weight loss

Unfortunately, these body weight control mechanisms often don’t work with weight gain to above the set-point. Weight gain, instead of leading to less appetite and a higher metabolism, often leads instead to a resetting of the set-point to the higher weight!

Weight loss surgery (gastric sleeve surgery, gastric bypass surgery), we are learning, changes this biology. Weight loss surgery, in effect, resets the body weight set-point to a lower weight. To date, weight loss surgery is the only thing we know of that does this. This is the key reason for why weight loss surgery works so much better than other weight loss methods.*
Weight loss surgery changes set-point

The long-term challenge for patients after weight loss surgery is to maintain weight loss. Surgery resets the body weight set-point to a lower weight, but surgery doesn’t change the reasons for why weight gain can occur. Excess calorie intake after surgery can cause weight gain and an increased set-point like it could before surgery. The key to long-term success is establishing good eating and exercise habits to prevent excess calorie intake.

Gastric Bypass Orange County – 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, alcohol addiction, bowel obstructions, and ulcers.

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.
