Gastric Bypass Can Transform Your Life

Gastric bypass (also known as roux-en-y gastric bypass, or simply bypass) can help you achieve long-term weight loss success and transform your life.*

Dr. Oliak frequently tells patients that, in his experience, weight loss after surgery pretty much makes everything better. Medical problems improve, energy improves, sleep improves, mobility improves, pain decreases, happiness and wellbeing improve.* Patients become more able to be active with their kids and families.*

Plus, published studies report that patients develop fewer medical problems over time and live longer after weight loss surgery!*

What’s not to like!

Well, the negatives are that surgery has risk, and doing well requires patients to do work. But, with a quality surgeon (like Dr. Oliak!), a quality program (like ours!), and a willingness to do the work, risk can be minimized, and the likelihood of a great long-term weight loss outcome can be maximized.*

Our Program

How Does Gastric Bypass Work?

Gastric bypass causes weight loss by restricting food intake and by changing the biology of weight regulation.

This biology of weight regulation is impressively good at maintaining bodyweight and preventing weight loss. This is why weight loss is so hard to accomplish, and virtually impossible to maintain.

Gastric bypass surgery changes this biology. In effect, surgery resets the bodyweight “set-point” to a lower weight (read more). With this biology change, long-term weight loss becomes possible!*

The challenge is that gastric bypass surgery doesn’t change the reasons for why weight gain can occur. Consuming excess calories can cause weight regain after surgery, as it could cause weight gain before surgery.

The keys to long-term success after gastric bypass surgery:*

  • Getting a quality operation
  • Establishing appropriate eating/exercise habits after surgery

In Dr. Oliak’s experience, 50% of success after surgery is because of the surgeon and program (good surgery, good patient care – education, follow-up, support), and 50% is because of the patient (good eating/exercise habits).*

Gastric Bypass Weight Loss

Weight loss after gastric bypass surgery typically occurs rapidly over 1-1.5 years.*

The published studies report an average of 65-70% excess weight loss at 1-3 years after surgery.* Long-term studies (10+ years) show that patients maintain the majority of their initial weight loss over time.*

Some surgeons and programs (like ours) report better weight loss averages than 65-70% of excess weight (some report worse). Our gastric bypass patients average 75-78% excess weight loss at 1-3 years after surgery.*

Variation in average weight loss results between different surgeons and programs occurs at least partly because of differences in how surgeons and programs do surgery and patient care.*

Gastric Bypass Risks?

The gastric bypass operation has been proven over 40+ years to be a safe operation, but complications can occur.

Early Complications – Leak

Leak is the most feared potential early complication after gastric bypass surgery. A leak is a hole that develops in an area of the surgery (stomach or intestine), generally early after surgery before complete healing has occurred.

Leaks are generally technical in nature, meaning they occur because of how the operations are done. A surgeon’s leak rate, in Dr. Oliak’s view, is an excellent measure of surgeon quality. Surgeon leak rates vary, according to the published literature, from 0% to 8% (Dr. Oliak’s leak rate is <0.1%).*

Late Complications
Several potential long-term complications can occur after gastric bypass surgery, including vitamin/mineral deficiencies, low blood sugar, alcohol addiction, bowel obstruction, and ulcers.

The risk for these long-term issues can be minimized with good surgery and patient care, but not completed eliminated.*

Why Gastric Bypass Surgery?

The 2 most common operations for weight loss are sleeve gastrectomy and gastric bypass.

Sleeve gastrectomy is more commonly performed, accounting for 70-75% of first time weight loss operations in the United States. Gastric bypass accounts for approximately 20-25% of operations.

Reasons to consider gastric bypass over sleeve gastrectomy include:

  • Gastric bypass is more established – proven safe/effective over >40 years
  • Diabetes remission in higher percentage of patients
  • Acid reflux resolution/prevention in higher percentage of patients
  • Possibly better weight loss in higher BMI patients (BMI >50)

About Gastric Bypass Surgery

Gastric bypass surgery (also known as roux-en-y gastric bypass, or simply bypass) involves surgically creating a very small pouch from the upper part of the stomach, and making a small connection between the stomach pouch and the intestine.

When food is consumed, it passes through the small pouch into the intestine, bypassing the majority of the stomach and the first part of the intestine.

The gastric bypass operation is done laparoscopically or robotically, using small incisions. The operation typically takes 1.5-2 hours.

The specific details of the gastric bypass operation, such as pouch volume/dimensions and stomach/intestine connection size/technique are not standardized. There is not an accepted “best way” to do the operation. Because of this, different surgeons do the gastric bypass operation in different ways.

Dr. Oliak does the gastric bypass operation by making a very small measured pouch, and a very small measured pouch/intestine connection. Dr. Oliak’s technique has resulted in excellent weight loss results over 17 years (>1000 operations).

Gastric Bypass Surgery Recovery

Because gastric bypass surgery is done laparoscopically (or robotically), recovery is generally rapid. Patients typically are discharged from the hospital 1-2 days after surgery, and return to work 2-3 weeks after surgery.

Gastric bypass patients typically remain on a liquid only diet for several weeks after surgery, and then slowly transition onto solid foods.

Gastric Bypass Patient Care – Education, Follow-Up, Support

Good patient care helps to ensure a safe and successful outcome. Surgery is a tool for weight loss, and patient education, follow-up, and support help patients to use the surgical tool effectively.

Dr. Oliak prioritizes thorough education both before and after surgery, frequent follow-up for the first 6-12 months after surgery, ongoing yearly follow-up after 1 year, and ongoing support.

Our Program

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.

BMI Calculator

Insurance companies generally require patients in the BMI 35-40 range to have weight-related medical problems, such as diabetes, high blood pressure, or sleep apnea.

Insurance companies often require the completion of a 3-month or 6-month medically supervised diet.
