If you’re frustrated with your initial bariatric surgery results or have gained back a significant amount of weight, you’re not alone. Studies have shown that a significant percentage of patients experience weight gain about two years after the procedure. 

The good news is that you don’t have to settle for regaining all the weight you worked so hard to lose. Gastric bypass revision surgery can repair or alter a previously unsuccessful weight loss surgery. Unlike gastric sleeve surgery or the traditional bypass technique, endoscopic gastric bypass revision surgery involves no incisions or staples, and less risk of severe complications. 

In this article, we’ll answer some of your most pressing questions regarding revision surgery, including the different types of procedures available, how much weight do you lose after gastric bypass revision, how to prepare for the procedure, and how to maximize weight loss after surgery. Read on to learn more! 

 

What’s Gastric Bypass Revision? 

It’s important to understand that, in many cases, gastric bypass failure is not the patient’s fault. While poor eating habits and a lack of physical activity can certainly hinder weight loss efforts, a gastric bypass surgery failure can mean a lot of different things.

For example, weight loss surgery is considered unsuccessful if the patient doesn’t lose at least 50% of their body weight or if they regain the weight after initial weight loss. Other factors include having a pouch that’s too large for you, hormonal or metabolic imbalances that weren’t addressed before surgery, or taking medications that may cause weight gain.

Fortunately, there are options available if you regain weight after gastric bypass surgery. As a first line of treatment, you can try diet and exercise. However, if these strategies weren’t effective before your initial bypass surgery, it’s possible they won’t be effective this time. Another option is a repeat gastric surgery, which involves reattaching the small intestine and potentially redoing the gastric bypass. However, a second surgery is often more complex and may have higher rates of complication.

What is the Best Revision Surgery for Gastric Bypass?

There are several types of revision surgeries to correct a failed gastric bypass, including surgical revision options, and endoscopic gastric bypass revision.

An endoscopic gastric bypass revision surgery is a quick and effective intervention that involves reducing an enlarged gastric pouch without the need for additional surgery, or incisions. This outpatient procedure is performed through an endoscope (a thin, hollow tube attached to a tiny camera and a suturing device) that’s inserted through the mouth. 

It prompts weight loss by reducing the size of your gastric pouch and the size of the outlet between your gastric pouch and your intestine. Endoscopic gastric bypass revision surgery is proven to increase feelings of fullness, curb food intake, and jumpstart the weight loss process again. 

Gastric Bypass Surgery Revision Success Rate

Like most procedures, the gastric bypass revision success rate depends on several factors. For instance, if the stomach has stretched significantly after the initial procedure, the revision surgery is expected to have a very high success rate. However, if the stomach is only mildly stretched, then the revision weight loss results may not be as significant, and other options, such as weight loss medications, might be needed. 

Gastric Bypass Surgery vs. Revision

While the goal of both gastric bypass surgery and gastric bypass revision is to help you lose weight, they are very different procedures. Gastric bypass revision, as the name suggests, is performed after a gastric bypass if the initial surgery wasn’t successful. The specifics of gastric bypasses vary depending on each patient’s individual situation, but generally speaking, most bypasses are performed laparoscopically, which involves inserting instruments through multiple small incisions in the stomach. Initial gastric bypass surgeries also have strict eligibility requirements, including having a body mass index (BMI) of 40 or greater, or a BMI between 35-40, and an obesity-related condition, such as diabetes or severe sleep apnea. 

Gastric bypass revision surgery, on the other hand, is performed by inserting an endoscope through the mouth, which means that you won’t have any additional scars. Another difference is that recovery times are significantly shorter, and there are no specific BMI requirements to undergo a revision procedure. 

Am I a Candidate for Gastric Bypass Revision?

The best way to know if you qualify for gastric bypass revision surgery is to schedule a consultation with a healthcare provider specializing in weight loss. Here are some signs that you may be a good candidate for endoscopic gastric bypass revision surgery:

  • You didn’t lose a significant amount of weight following your initial gastric bypass procedure 
  • You’ve gained a significant amount of weight in the months or years following your bariatric surgery
  • You struggle with chronic acid reflux or other surgery-related complications 
  • You don’t feel full after eating

Reasons for a Gastric Bypass Revision

The most common reason for gastric bypass revision surgery is weight regain. Other reasons include:

Inadequate Weight Loss

Patients are expected to lose between 50-70% of their initial body weight, depending on the initial bariatric procedure. But sometimes, this weight loss isn’t as substantial as expected. A gastric bypass revision surgery can help correct this. 

Complications From the Initial Surgery

Sometimes, gastric bypass patients lose a significant amount of weight but experience complications such as leaks, strictures, or ulcers. A revision procedure may be necessary to address these complications.

Malabsorption Issues

Malabsorption, in the context of bariatric surgery, means the restriction of the absorption of the nutrients in the food you eat. While malabsorption is not always considered a negative side effect, in extreme cases, it may lead to malnutrition, vitamin deficiencies, weakened bones, and anemia. 

Dumping Syndrome

Some patients who undergo gastric bypass surgery develop dumping syndrome, which occurs when the solid parts of a meal get “dumped” directly into the small intestine without being digested. While dumping syndrome is a common side effect of gastric bypass surgery, revision may be needed in severe cases to avoid further complications.

Hernias

Some patients may develop hernias (protrusions of tissue through the abdominal wall) following gastric bypass surgery. Revision surgery may be performed to repair these and correct any associated issues.

Pouch Stretching

Over time, the pouch created during the initial surgery may stretch, allowing it to hold larger volumes of food, which can compromise the effectiveness of the procedure. Endoscopic revision surgery may be necessary to resize the pouch.

 

How Much Weight Do You Lose After Gastric Bypass Revision?

How much weight you lose after gastric bypass revision will depend on a number of factors, including the reason(s) why the surgery failed, your lifestyle habits and medical history, and the type of procedure you undergo. For example, weight loss after sleeve-to-bypass revision can be significant, with patients losing up to 75% of their excess weight following the procedure. 

Gastric bypass revision surgeries, including a minimally invasive endoscopic procedure, will typically result in smaller weight loss than the original surgery. This is because most patients who undergo revision surgery will have less weight to lose. Moreover, as with any weight loss intervention, results can take time. Most people can expect to lose 10 to 15% of their total body weight within 12 months of the procedure. 

How Much Weight Do You Lose with Gastric Bypass Surgery?

The amount of weight loss depends on the type of bariatric surgery you choose and your general health. However, patients can expect to lose between 50 and 60% of their excess weight one year after the surgery. If you didn’t lose weight at all or experienced less weight loss after gastric bypass surgery, you may want to consider revision surgery. 

 

Benefits of Bariatric Gastric Bypass Revision

The main benefit of bariatric gastric bypass revision surgery is reinitiating weight loss to achieve your desired goals. However, an endoscopic revision procedure has some additional benefits, including: 

Reduced Surgical Risks

The endoscopic nature of the procedure eliminates the need for incisions, lowering the risks typically associated with open surgeries, such as bleeding and hemorrhage, wound infection, and scarring. 

No Overnight Stays

Unlike traditional surgeries that often require patients to stay in the hospital for monitoring, endoscopic gastric bypass revisions are performed on an outpatient basis. This means that you can return home on the same day of the procedure.

Minimal Recovery Time

The minimally invasive nature of the endoscopic procedure allows for a quicker recovery compared to traditional surgeries. Most patients are able to resume their daily activities within 2 to 3 days following endoscopic gastric bypass revision surgery.

Reversal of Complications

A revision procedure can reverse problems and complications that may have arisen from the initial gastric bypass surgery, such as pouch stretching and dumping syndrome, without resorting to more invasive surgical methods. 

Minimal Anesthesia 

Endoscopic gastric bypass revision procedures are typically performed under IV sedation rather than prolonged general anesthesia, lowering risks such as allergic reactions to anesthesia, hypothermia, itching, nausea, and vomiting. 

 

 

 

What to Expect After Gastric Bypass Revision

If you’re undergoing gastric bypass revision surgery, chances are you’re familiar with the procedure and recovery process of traditional gastric bypass surgery. Luckily, endoscopic revision surgery is not only considerably less invasive, but the recovery process is also quicker and simpler. Below are our top recommendations for how to prepare yourself physically and mentally for the procedure and what to expect in the days and weeks following the intervention. 

 

Pre-Op Instructions

Gastric bypass revision can significantly improve your quality of life. But for the procedure to be as safe and effective as possible, you’ll need to take some steps to ensure you’re prepared. Here are some things to keep in mind:

  • Talk to your doctor about any specific pre-op testing and medications 
  • Opt for high-protein, low-calorie foods that are easy to digest
  • Stop smoking 
  • Drink plenty of water 
  • Follow your doctor’s dietary recommendations
  • Start exercising
  • Limit caffeine intake
  • Sometimes weight gain is directly related to our mental health. Seek counseling or join a support group if you need help addressing emotional eating

 

After Your Procedure

Endoscopic bypass revision surgery is often performed in an outpatient setting and typically takes around 30 minutes to complete. Following the procedure, most patients experience mild nausea and some abdominal pain or discomfort. These symptoms can usually be controlled by medication and typically last less than a week. 

A dedicated dietitian will provide food and physical activity recommendations for the days and months after your revision surgery. Following these recommendations will be an important part of maximizing your results and maintaining weight loss over the long term.

How Much Weight Do You Lose After Gastric Bypass Revision in the Long Term? 

While the long-term success rate of gastric bypass revision surgery is high, you’ll need to modify your lifestyle habits to reap the benefits of your procedure for years to come. Here are some tips to maximize your weight loss following the procedure and keep the weight off for years to come:

  • Eat smaller meals
  • Focus on high-protein foods
  • Incorporate daily physical activity
  • Prioritize sleep
  • Manage stress
