What Are the Complications of Sleeve Gastrectomy?

What Are the Complications of Sleeve Gastrectomy?

Sleeve Gastrectomy or gastric sleeve surgery, is a surgical weight loss procedure. This procedure is performed by removing about 75-80% of the stomach and leaves a tube-shaped stomach that is about the size of a banana. The main purpose of this surgery is to restrict the amount of food that patients can consume by limiting the size of the stomach. It’s usually performed on patients who have tried to lose weight by following strict diets or doing exercise but couldn’t get a satisfying result. In general, sleeve gastrectomy may be a solution for patients who are suffering from obesity and other related serious health issues.

Gastric sleeve surgery is one of the most common procedures today and it has a high rate of success. The food that can be eaten and the number of calories that can be taken are decreased because of the restricted stomach size. However, sleeve gastrectomy results also depend on embracing a healthy lifestyle after the surgery. Therefore, patients need to be willing to make permanent changes in their life.

Sleeve gastrectomy is considered safe in comparison to other common weight loss procedures. It generally has positive outcomes and has minimal chance of complications when performed by a competent surgeon.


Bleeding is the most common complication after a surgical operation. It doesn’t pose a huge problem if it occurs on a thin suture, but greater external or internal bleeding is a very critical issue. You should immediately contact your doctor in this case.  

Wound Infection

Wound infection can seriously affect the healing process. You should take great care to keep your incision clean and dry to avoid any infections.

Dyspepsia, Nausea or Diarrhea

Physical symptoms like dyspepsia, nausea or diarrhea are more frequent issues after gastric sleeve surgery. Many patients experience these problems for only a few days. Additionally, some patients may have problems of decreased food tolerance to rice, pasta, bread or red meat after the operation.

Failure to Lose Weight

This is one of the most serious issues that can be encountered after the surgery, since the operation’s main purpose is to lose weight. There may be several reasons leading to this result, regarding the procedure itself or the patient’s behaviors afterward.  

Regaining Weight

Although patients lose a significant amount of weight after the sleeve gastrectomy operation, some may start gaining weight again after a few years. As stated above, there is always a risk of regaining weight if the patients don’t follow a healthy diet.

Persistence of Chronic Health Problems

Obesity brings along many chronic diseases like diabetes. Some patients choose gastric sleeve surgery to get rid of these diseases by losing weight. However, you should be aware that certain chronic diseases aren’t going to disappear magically in a day. You will get rid of these chronic health problems in a few months -or maybe a year- with a healthy weight loss process.

Sagging Skin

Considering the number of pounds you are going to lose after the surgery, it is not surprising that this procedure may leave some saggy skin afterward. You can minimize this problem by exercising regularly.

Hair Loss

You are likely to experience hair loss, if you don’t take the vitamins you need after the surgery. You can prevent excessive hair loss by following a healthy and balanced diet.

The complications mentioned above can occur after almost all surgeries but things are unlikely to go that wrong with a specialist doctor and team. You can contact us for a free consultancy and more information about sleeve gastrectomy.
