What is gastric bypass surgery?

Gastric bypass surgery, or Roux-en-Y gastric bypass, greatly differs from the gastric banding bariatric surgeries, because the operation involves making changes to your digestive system for the purpose of reducing the absorption of calories, as well as nutrients.

Because of these changes to the digestive system, gastric bypass often leads to the highest amount of weight loss of all the bariatric surgeries we perform. For the same reasons, it is also a riskier form of bariatric surgery, because it is more invasive than a procedure like the LAP-BAND®.

Gastric bypass surgery is one of the top options for those seeking weight loss surgery. At West Medical, we’re dedicated to guiding you through the entirety of your gastric bypass treatment process. Below, you’ll find some valuable information that may address some of your questions and concerns. You can also schedule a consultation with a bariatric surgeon to discuss your weight loss options.

What is gastric bypass surgery

How gastric bypass surgery works

Gastric bypass surgery involves the creation of a smaller stomach pouch that is separate from the rest of the stomach. This method decreases stomach capacity and, in turn, causes patients to feel fuller at a faster pace. The larger part of the stomach doesn’t hold any food, but still maintains all of its normal blood vessels.

Gastric bypass surgery includes stapling the stomach as well as the rerouting of the intestinal tract. These major changes to the digestive system change the way nutrients are absorbed, as well as limit the amount of food you eat before feeling full. This method is preferable for some patients because not only does it reduce the size of food portions you can eat, but also reduces the amount of calories and nutrients your body absorbs.

Benefits of our gastric bypass surgery

Gastric bypass was one of the first bariatric surgery procedures performed, and initially many of these procedures were performed “open” meaning with a large incision. Medical developments have given surgeons the ability to perform gastric bypass laparoscopically today, meaning with very small incisions. Gastric bypass has decades of study data, and can often provide faster weight loss than other methods, such as the LAP-BAND or gastric sleeve. Gastric bypass has shown particularly beneficial results for patients with type 2 diabetes. You can learn more about diabetes and bariatric surgery here.

At West Medical we prioritize your safety, comfort, and health. Your West Medical gastric bypass surgeon will explain your options clearly so you can make an informed, empowered decision if you think the bypass is a good choice.

Gastric bypass risks

The gastric bypass operations has a slightly higher level of risk than the gastric band or gastric sleeve. This is because it is a more invasive operation, but also leads to the highest amount of weight loss on average. The risks of gastric bypass include:

  • The reduction in caloric absorption is greater than other bariatric surgeries, but can result in nutrition deficiency.
  • Ineffective healing of the areas that were stapled and sealed can result in infection, leakage, and the formation of abscesses.
  • When consuming desserts and starchy foods, dumping syndrome has a high chance of occurring.
  • Nausea and subsequent vomiting can take place, which, in turn, may cause strictures, requiring additional surgery.
  • Gastric bypass surgery has been linked to hair loss in some patients.

When you meet with a gastric bypass surgeon at West Medical, he or she will explain the risks and benefits of the procedure in detail. When you make a decision about your health, you are taking an important step. That step should be taken with all the education needed to feel as though you’re in control of your journey. We are here to guide and support you every step of the way. You can contact us here.

Uncertain whether to get gastric bypass surgery or gastric sleeve?

Gastric bypass revision

Gastric bypass revisions are typically performed when patients who have previously undergone gastric bypass surgery find that their stomach pouch and gastric outlet have stretched, no longer restricting intake and curbing appetite as effectively as before. Bariatric surgeons performing gastric bypass revisions address the stretched pouch and outlet, making them smaller in order to ensure that your weight loss can get back on track.

Gastric bypass revisions can be a safe and successful method for ensuring your bariatric surgery delivers the desired results. These procedures are performed laparoscopically, using minimally invasive techniques that cut down on post-operative pain and make recovery times quicker. If you are interested in being evaluated for a revision of your gastric bypass in Orange County or Los Angeles, call us at (855) 690-0565.

Gastric Bypass FAQs

What's the difference between duodenal switch vs. gastric bypass?

Gastric bypass surgery has long been known as the “gold standard” for patients who needed to lose 200 lbs or more or have a BMI over 50.

Gastric bypass reduces stomach size by rerouting food from the stomach and bypassing most of the small intestine.

A “duodenal switch” includes a sleeve, and creating a smaller stomach, rerouting the small intestine but not removing it, as is performed in a gastric bypass surgery.

What is the pre-op diet like for gastric bypass?

The pre-op diet for gastric bypass surgery is typically high-protein, low calorie shakes that are easy to digest and provide the nutrients your body needs. This diet can help reduce the fat around the liver and make it possible to perform your surgery laparoscopically for a faster, safer recovery. Your diet prior to surgery will likely require strict portion control, along with decreasing intake of fats, sugar, alcohol, and carbohydrates.

What is the post-op diet like for gastric bypass?

The first few days will be a liquid diet only, after which you can proceed to pureed foods, and then solids. You will need to drink 64 ounces of healthy liquids each day, but none consumed 30 minutes prior or following meals. You will be directed to eat lean, protein-rich foods, avoid foods high in fats or sugar, limit alcohol and caffeine intake, and take the supplements as directed. Ensure all foods are chewed thoroughly.

Will I have excess loose skin after the procedure? What are my options?

After losing a significant quantity of weight, you may be left with excess loose skin that has been stretched to the point where it is unable to reform itself around your new body contour. Many patients, once they have reached their weight loss goal, choose to undergo a custom surgical procedure to remove excess skin, fat, and tissue, called “body contouring.”

Will I get ulcers after having gastric bypass?

At West Medical, we want our patients to be fully educated on any risks or complications associated with weight loss surgery, including the development of ulcers. An ulcer can develop at the surgical staple line in some cases. To avoid developing ulcers, we ensure our patients know what to avoid, which generally includes smoking, taking aspirin or non-steroidal anti-inflammatory medications or NSAIDs. While it is statistically unlikely that you will get an ulcer, we carefully monitor our patients after surgery, and can treat this complication successfully should it arise.
