The gastric bypass operation involves constructing a very small stomach pouch from the existing stomach, and connecting this small stomach pouch to the intestine. The gastric bypass operation has been established to be safe and effective for weight loss over more than 40 years, and is considered to be the best weight loss operation for diabetes and reflux/gerd.

Our Orange County gastric bypass program has an established record of achieving excellent, industry-leading patient outcomes.* To learn more about gastric bypass surgery and our Orange County gastric bypass program, contact our office to schedule a free, no-obligation educational consultation with Dr. Oliak in Brea or Irvine.

About Gastric Bypass Surgery

Gastric bypass involves creating a very small pouch (about 1 ounce) from the upper part of the stomach, and making a small connection (about 1/2 inch diameter) between the stomach pouch and the intestine. Another intestinal connection is also made so that the bypassed stomach has a way to empty.

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

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

About Gastric Bypass Outcomes

The gastric bypass operation has been established as safe and effective over more than 40 years. The better studies show that average weight loss after gastric bypass surgery is very good, and complication rates are low.*
More about gastric bypass outcomes

The published gastric bypass literature, however, clearly shows that different surgeons and programs have different patient outcomes statistics, for both weight loss results and complication rates. Why? Because different surgeons and programs do the gastric bypass operation and patient care (education, follow-up, support) differently, and these differences affect patient outcomes.

Different surgeons do the gastric bypass operation differently because there is not consensus on how the gastric bypass operation should be done. There is not agreement on details like what size/shape/dimensions the pouch should be, or what size the pouch/intestine connection should be, or how the pouch/intestine connection should be done, etc. Because of this lack of consensus, different surgeons do the gastric bypass operation differently, and these differences affect patient outcomes.

Different surgeons/programs do patient education/follow-up/support differently, and these differences also affect patient outcomes. Surgery is a tool to help patients to lose weight, and not a cure for obesity. To achieve good long-term success, patients must establish appropriate eating/exercise habits after surgery, and patient education/follow-up/support helps to ensure that these changes happen.

Our Orange County Gastric Bypass Program

Outcomes matter – studies clearly show that patient outcomes vary between different surgeons/programs. For example, one large 2017 study (abstract) showed that the rate for serious complications after weight loss surgery varied 17-fold (0.6%-10.3%) across 165 different bariatric surgery centers of excellence programs nationwide! Why? Because there are different surgeons at the different centers who do the operations differently.

Dr. Oliak has always prioritized achieving the best possible outcomes for his patients. By always prioritizing excellent surgery and high-quality patient education/follow-up/support (our program), Dr. Oliak has established a long record of gastric bypass patient outcomes – weight loss results, complication rates – that rank among the best in the weight loss surgery field (our outcomes).*

How Does Gastric Bypass Work?

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 Choose Gastric Bypass?

Gastric bypass is the most established and best studied of the weight loss operations. Its safely and effectiveness have been proven over more than 40 years. For this reason the gastric bypass operation is often considered to be the gold standard operation for weight loss.

The most popular operation for weight loss currently is sleeve gastrectomy. Compared to the gastric bypass operation, the gastric sleeve operation is less invasive, and therefore associated with less risk. In several situations, however, the gastric bypass is generally considered the better choice:

Gastric bypass is the best operation 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/Severe 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 an initial 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.

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, bowel obstructions, ulcers, etc.

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.

Gastric Bypass Orange County – Payment Options

Payment options for gastric bypass surgery with Dr. Oliak include PPO insurance and self-pay. Dr. Oliak does not accept HMO or MediCal insurance.

PPO insurance has become more restrictive over the past several years. When weight loss surgery is a covered benefit (often it is not), there are generally many requirements that must be met before the insurance company will preauthorize surgery. An increasingly common requirement is having to complete a 6 month medically supervised diet. Call the office for a free insurance verification to check coverage.

For patients without PPO insurance coverage for weight loss surgery, Dr. Oliak offers competitive gastric bypass Orange County self-pay prices, and attractive gastric bypass Orange County financing options. Approximately 50% of our patients are self-pay patients due to the above insurance challenges.
