Sleeve vs Bypass, Surgery, for Weight Loss, Pros and Cons, 😱 70-80% Of Your Stomach Removed?

Hello friends, today we will discuss the comparison between sleeve gastrectomy and bypass surgery for weight loss.

Bypass surgery refers to procedures such as meningastric bypass, rheumatoid gastric bypass, and other types of bypass surgeries for bariatric or weight loss purposes. On the other hand, sleeve gastrectomy involves reducing the size of the stomach without performing any bypass.

Many individuals who have decided to undergo bariatric surgery often face confusion about which procedure to choose. In this video, we will focus on the conditions where sleeve gastrectomy is more beneficial than bypass surgery. We will also cover the advantages of bypass surgery over sleeve gastrectomy in a separate video.

In sleeve gastrectomy, the size of the stomach is reduced, as shown in the diagram. The upper part of the stomach, known as the fundus, is also removed during this procedure. After sleeve gastrectomy, several changes occur in the body. The fundus, which secretes hunger hormones, particularly the ghrelin hormone, leads to decreased hunger immediately after surgery. Additionally, the smaller stomach size results in feeling full after consuming only a small amount of food. The reduced stomach size also facilitates quicker movement of food through the intestines, resulting in less food absorption. Furthermore, these changes in the body's hormonal balance reverse the negative effects of obesity, including conditions like diabetes, high blood pressure, bad cholesterol, and joint pains.

These positive effects are associated with sleeve gastrectomy. In contrast, bypass surgery primarily reduces the quantity of food intake, but it does not bypass the normal path of food. The food travels from the stomach to the duodenum, the first part of the small intestine, where it mixes with liver and pancreatic juices before moving to the jejunum, where most of the absorption occurs. While the speed of eating is increased, reducing food absorption to some extent, the food follows its normal course through the small intestine. In any form of bypass surgery, the initial parts of the intestine are bypassed, diverting the food directly from the stomach to the distal part of the small intestine. This bypass results in reduced food absorption in the body but also poses a risk of deficiencies in proteins, minerals, and multivitamins, requiring increased supplementation to avoid deficiencies.

The risks of deficiencies exist in sleeve gastrectomy as well, but they are relatively lower since the food follows its normal path. Even though you consume less food and take supplements to some extent, the risk of deficiencies is reduced. However, in bypass surgery, despite supplementation, there is a possibility that the parts responsible for supplement absorption are bypassed, resulting in a higher risk of deficiencies.

Considering these factors, sleeve gastrectomy is a better option for selective patients compared to bypass surgery. It is important to note that sleeve gastrectomy may not be the best choice for everyone. The simplicity of sleeve gastrectomy makes it suitable for patients with lower body mass index (BMI) and fewer complications. In our practice, we generally recommend sleeve gastrectomy for patients with a BMI less than 40. If your BMI is higher than 40, the results may not be as satisfactory because sleeve gastrectomy only reduces food intake without bypassing it. Additionally, if you are unable to maintain proper nutrition and physical activity, the final outcome may not be optimal. For simpler cases, we prefer simpler surgeries, while more complex cases without contraindications for bypass surgery are recommended to undergo bypass surgery.

To summarize the advantages of sleeve gastrectomy:

1. Simplicity: Sleeve gastrectomy is a simpler surgical procedure.
2. Lower BMI: It is a suitable option for patients with a lower BMI.
3. GERD: Sleeve gastrectomy is preferred over bypass surgery for individuals without significant

gastroesophageal reflux disease (GERD) symptoms.
4. Chronic diseases: In chronic conditions where bypass surgery may be more aggressive and complicated, sleeve gastrectomy is a better choice.
5. Pre-pregnancy: For females planning to conceive, sleeve gastrectomy is considered a favorable option if the weight is not excessively high.
