When weight loss surgery doesn’t work: Why some people fail with the gastric sleeve

Are you one of the many individuals who have undergone gastric sleeve surgery, yet still haven’t achieved your desired weight loss results?

You’re not alone. While this procedure is highly effective for most patients, there are some who don’t experience the expected outcomes. In this blog post, we will explore the reasons behind why some people fail with the gastric sleeve and discuss alternative options to help those struggling to lose weight.


Many people who undergo weight loss surgery, such as the gastric sleeve, are successful in losing weight. However, there are a small percentage of people who do not lose weight or who regain the weight they lost. There are a number of possible reasons for this:

The first reason is that the person may not have been a good candidate for surgery in the first place. Surgery is only effective if the person is committed to making lifestyle changes, such as eating healthy and exercising regularly. If someone is not willing to make these changes, surgery will not be successful.

Another reason why some people fail to lose weight after surgery is that they do not follow their doctor’s instructions. It is important to follow all post-operative instructions, such as attending regular follow-up appointments and taking vitamins and minerals as recommended.

It is also possible that the surgical procedure itself was not done properly. This is rare, but it can happen. If there are complications from surgery, it can make it more difficult to lose weight or even cause weight gain.

Finally, some people simply have a higher than average metabolism or store fat differently than others. This means that even if they eat less and exercise more, they may still not lose weight. This is often referred to as “metabolic resistance.”

Types of Weight Loss Surgery

There are many different types of weight loss surgery, each with its own set of benefits and risks. The most common types of weight loss surgery are gastric bypass surgery, laparoscopic gastric banding, and sleeve gastrectomy.

Gastric bypass surgery is the most effective type of weight loss surgery. It involves creating a small pouch in the stomach and reconnecting the small intestine to this pouch. This reduces the amount of food that can be eaten at one time and also decreases the absorption of calories and nutrients.

Laparoscopic gastric banding is less effective than gastric bypass surgery but has fewer complications. It involves placing a band around the stomach to create a smaller stomach pouch. This limits the amount of food that can be eaten and leads to feeling full sooner.

Sleeve gastrectomy is the least effective type of weight loss surgery but has the lowest risk of complications. It involves removing a portion of the stomach, which limits the amount of food that can be eaten and leads to feeling full sooner.

The Gastric Sleeve Procedure

The gastric sleeve procedure is a weight loss surgery that involves removing a portion of the stomach. This decreases the amount of food that can be consumed and also reduces the hormones that are responsible for hunger. For some people, this surgery is successful in helping them lose weight and keep it off. However, there are some people who do not have success with this surgery.

There are several reasons why the gastric sleeve might not work for some people. First, the surgery itself may not be successful. This can happen if the stomach is not properly divided or if there are complications during surgery. Second, even if the surgery is successful, some people may not be able to stick to the required diet and lifestyle changes. After surgery, patients need to eat smaller meals more often and avoid high-calorie foods and beverages. They also need to make sure they get enough protein and nutrients. Some people find it difficult to make these changes and end up gaining back the weight they lost.

Finally, there is always the possibility that weight loss surgery will not be right for you. If you are considering this type of surgery, it is important to talk to your doctor about all of your options and what is right for your specific situation.

Reasons Why People Fail To Lose Weight With Gastric Sleeve Surgery

There are many reasons why people fail to lose weight with gastric sleeve surgery. The most common reason is that they don’t change their eating habits. They continue to eat the same foods in the same quantities as before surgery. This doesn’t work because the stomach is smaller after surgery and can’t hold as much food.

Another common reason for failure is not getting enough exercise.

10 Tips To Follow For Weight Loss Surgery Success And Long-term Maintenance

Gastric sleeve surgery doesn’t magically make you lose weight. You have to do your part by making healthy lifestyle choices, including getting regular exercise.

Many people also fail to lose weight because they don’t follow their doctor’s directives after surgery. This could mean not taking vitamins or other supplements, not going to follow-up appointments, or not following a special diet plan. All of these things are important for success after gastric sleeve surgery. Finally, some people simply have a higher body mass index (BMI) than others and no matter how much weight they lose, they will always be considered obese. For these people, other weight loss options, such as gastric bypass surgery, may be more successful

Alternative Weight Loss Solutions For Those Who Don’t Respond Well To Gastric Sleeve Surgery

If you’re considering weight loss surgery, the gastric sleeve is usually the first procedure that comes to mind. It’s less invasive than other options like the gastric bypass, and it has a lower risk of complications.

But not everyone who has Gastric Sleeve Surgery will lose weight, or keep the weight off long term. In fact, some people gain back all the weight they lose, plus more.

So what can you do if Gastric Sleeve Surgery doesn’t work for you?

There are a few alternative procedures that your doctor may suggest. These include:

Gastric Banding: This surgery involves placing a band around the stomach to create a smaller pouch for food. The band can be adjusted to make the stomach smaller or larger, depending on the patient’s needs.

Gastric Balloon: A balloon is placed in the stomach and inflated to take up space so that patients feel fuller faster. The balloon is temporary and must be removed after 6 months.

Duodenal Switch: This is a more complex surgery that involves both removing a portion of the stomach and rerouting the small intestine. It’s typically reserved for patients who are extremely overweight and have failed to lose weight with other methods.

Whatever alternative your doctor suggests, it’s important to remember that weight loss surgery is not a quick fix – it’s a lifelong commitment. You

How to Manage Expectations After Weight Loss Surgery

Weight loss surgery is a serious commitment. It requires making permanent changes to your eating and exercise habits. But even with the best of intentions, weight loss surgery doesn’t always work.

Some people regain the weight they lost, while others never lose very much weight at all. If you’re struggling to manage your weight after surgery, it’s important to understand why.

There are a number of reasons why weight loss surgery may not be successful. One reason is that surgical procedures can only do so much. They can’t change your lifestyle or make you more motivated to lose weight.

Another reason is that gastric sleeve Surgery is not right for everyone. People who have certain medical conditions, such as diabetes or sleep apnea, may not be good candidates for this type of surgery. Likewise, people who are unable to stick to a strict diet and exercise plan may not see the results they want.

If you’re considering weight loss surgery, it’s important to discuss your expectations with your surgeon beforehand. It’s also important to remember that even if the surgery is successful, you’ll still need to make lifestyle changes to maintain your weight loss in the long term.


Weight loss surgery such as the gastric sleeve can be a great tool to help those with bodyweight challenges, but it doesn’t always work long-term. For some, lifestyle changes and medical treatment can still help them reach their goals over time. It is important to understand the possible risks involved in this type of surgery and ensure that you are fully prepared before making any decisions.
