Gastric Bypass

On this page, you’ll learn more about gastric bypass surgery, what it is, and how it works. You’ll also learn more about potential gastric bypass complications, and the benefits this type of procedure offers you for weight loss.

The Roux-en-Y gastric bypass surgery, commonly called gastric bypass, is a popular weight loss surgery that has been referred to as the gold standard of bariatric surgery. The gastric bypass has been performed for more years than the gastric sleeve, so there is more long-term data on this procedure.

Patient Journey

From beginning to end, the journey for a patient undergoing bariatric care is full of changes. It will require persistence and discipline, but at the end it is all worth it. Feel free to learn more about the patient journey.

What is Gastric Bypass?

The Roux-en-Y gastric bypass procedure is usually performed laparoscopically (i.e. keyhole surgery with a telescope). In this gastric bypass operation, the stomach is completely divided with a stapler to leave a pouch that initially measures only 25 mls. The small bowel is divided and the divided end brought up and joined to the small stomach pouch. The other small bowel end is joined back on to the small bowel about a meter down from the stomach. Thus the whole stomach is bypassed apart from a tiny pouch. This operation works in two ways:

  1. Restriction: the small pouch restricts the volume of food you can eat at one meal
  2. Malabsorption: the reconfiguration of the small intestine, results in some of the food you eat passing through the intestine without being absorbed.

What are the Advantages of Gastric Bypass?

Gastric bypass is an effective weight loss operation in most patients (although where patients end up is always dependent on how they use the tool they are given). Advantages of gastric bypass:

  1. More rapid weight loss than banding
  2. Dumping offers a useful deterrent to eating high calorie food and drinks
  3. Long track record- the gastric bypass operation has been around in various forms for 30 years
  4. There is nothing to break or erode
  5. About 60-70% EWL over 2 years

GASTRIC BYPASS AND DIABETES

Diabetes is a leading cause of death in the United States, so it is important to recognize that the bypass can be a particularly good choice for patients who have type 2 diabetes. In studies, patients with diabetes who undergo gastric bypass surgery experience a remission of their diabetes as soon as days after their operation. This is particularly interesting because there is no way that the weight lost over a few days could lead to remission of diabetes. There appears to be a physiological change that happens from gastric bypass surgery that may treat diabetes. Although this is not the case for all patients, those with diabetes should be considered for gastric bypass surgery. According to the American Society for Metabolic and Bariatric Surgery (ASMBS), approximately 80% of patients who have gastric bypass surgery go into remission of their type 2 diabetes.

What are the Disadvantages of Gastric Bypass?

Disadvantages of gastric bypass:

  1. This procedure has a slightly higher serious complication rate than some of the other operations because of multiple staple lines and bowelconnections that can potentially leak.
  2. There is a need to take oral supplements of iron, vitamins and calcium for life, and some patients also need Vitamin B12 injections.
  3. Recovery time is slightly longer than after other procedures.

Lifestyle Changes after Gastric Bypass Surgery

After Bariatric Surgery Lifestyle Changes

Adjusting to your post bariatric surgery diet and lifestyle is one of the most important keys to your long-term success. Develop healthy daily habits based on eating in moderation that match your new body instead of failed eating patterns that can ultimately lead to poor health, fatigue, depression and attempts at binge eating. Making a commitment to lifestyle change will bring fast & substantial weight loss. Let us show you how.

Is permanent weight loss after bariatric surgery possible? Absolutely! But you aren’t going to find weight loss success by merely having restrictive weight loss surgery. Get thin quick schemes are a dime a dozen.  They are usually costly plans that promise fast weight loss. They work too – temporarily. The problem with fast weight loss plans alone is they are not long-term solutions to losing weight and keeping it off.

Tips to Avoid Feeling Deprived While Dieting (even before entering our program)

  • Learn and adhere to a sensible diet plan
  • Think lifestyle change rather than sticking with the diet mentality
  • Find new and exciting way to stay motivated
  • Indulge in your bariatric treats once in a while
  • Find enjoyment in activities other than eating
  • Reward yourself for reaching weight loss goals, but not with food.
  • Connect with friends and ask for support
  • Be accountable for your eating, even on your down days.
  • Eat small meals at specific schedules to avoid feeling hungry
  • Don’t skip meals
  • Create lighter versions of your favorite meals that you can enjoy eating

Post Surgery Diet

Post bariatric surgery diet guidelines are fully discussed with patients during their comprehensive nutritional evaluation prior to surgery.  Patients follow a Stage I diet for the first 4-6 week after surgery.  This includes all foods that are soft, mushy and/or pureed consistencies.  Examples for pureed foods are anything blended and smooth such as baby foods, fruitless yogurt, cottage cheese and hummus.  Soft/mushy foods include chopped up ground meats such as turkey, veal, chicken or pork, soft, white, flaky fish that is baked, broiled or grilled, scrambled eggs and egg whites.  Solid foods of all kinds should be completely avoided until weeks 4-6 or when the surgeon allows it.

This practice stresses the importance of good hydration, using non carbonated, decaffeinated, sugar free beverages.  We always promote good quality proteins to be consumed from day one after bariatric surgery.  High sugar and high fat foods are limited and very specific guidelines are provided to help equip patients with a clear-cut way to determine which foods are healthy for them to eat.  Fruits, vegetables, and high fiber foods are reintroduced after the first 3 months.  All patients get full details on dietary progression from our experienced nutritionists at their follow up visits.

The New York Bariatric Group is fully dedicated to promoting high standards for nutritional health. That doesn’t mean that patients should not enjoy eating. The New York Bariatric Group weight loss program has been designed to help patients lose weight rapidly, but provide you with resources to help enjoy your new lifestyle by keeping the flavor and fun in eating. Each patient is given the option to enroll in our Store. We brought together great tasting meals and supplements for breakfast, lunch, dinner and even snacks which can be ordered on our website.

How does gastric bypass surgery work?

During the gastric bypass procedure, the stomach is completely divided with a stapler to leave a small pouch that will now serve as your new stomach. Additionally, the small bowel is divided and the divided end is brought up and joined to the small stomach pouch. In doing this, you NYC gastric bypass surgeon allows the majority of your stomach to be bypassed, except for this little pouch. Because the weight loss surgeon bypasses most of your stomach, you will feel full more quickly. You also will not absorb as many calories because the food is not going through your entire intestinal path.

With the Surgical Obesity Service, the Roux-en-Y gastric bypass procedure is usually performed laparoscopically (i.e. keyhole surgery with a telescope); however in some cases it may be necessary to perform an open procedure. This type of bypass operation has proven to be an effective, consistent way of losing weight and keeping it off.


Advantages of gastric bypass surgery

Gastric bypass is an effective weight loss operation in most patients. It generally leads to more rapid weight loss than the Lap Band and the sleeve gastrectomy. The gastric bypass is considered a standard of bariatric surgery because it has the longest history. Various forms of this operation have been done for about 30 years, so we have more data and experience than we do with other, newer obesity treatments.

There is a side effect of the gastric bypass called dumping syndrome. Although some think of dumping syndrome as a negative side effect, it can also be thought of as an advantage. Dumping syndrome is stomach pain that comes from eating high calorie foods, and this pain can serve as a useful deterrent from eating foods that will hamper your weight loss efforts. Another advantage of the gastric bypass is there are no devices put into your body, so there is nothing that may break or erode, like there can be with the Lap Band surgery.

To summarize, advantages of gastric bypass include:

  • More rapid weight loss than banding
  • Dumping offers a useful deterrent to eating high calorie food and drinks
  • Long track record- the gastric bypass operation has been done for over 40 years
  • There is nothing to break or erode

Disadvantages of Gastric Bypass Surgery

The gastric bypass surgery is more complex than either the gastric sleeve or Lap Band. Similarly, the recovery time is somewhat longer than it is with either the sleeve or Lap Band. This added level of complexity and the rerouting of the intestines means that the bypass has a slightly higher rate of serious complication rate than some of the other operations.

One reason NYC gastric bypass patients lose so much weight is that the operation leads to fewer calories being absorbed by the body. However, this can also lead to a disadvantage of the operation. When fewer calories are absorbed, fewer nutrients are also absorbed. To help avoid further gastric bypass complications, patients need to take oral supplements of iron, vitamins and calcium for life, and some patients also need Vitamin B12 injections.

To summarize, disadvantages and complications of gastric bypass include:

  • This procedure has a slightly higher rate of complications than the other operations (i.e. gastric banding, sleeve gastrectomy) because of multiple staple lines and new bowel connections. To help avoid further gastric bypass complications, there is a need to take oral supplements of iron, vitamins and calcium for life, and some patients also need Vitamin B12 injections. Recovery time slightly longer than after banding and sleeve gastrectomy.
  • Residual stomach capacity: 30-50mls
  • Estimated weight loss: 60-70% EWL over 2 years.
