Gastric Sleeve Vs Gastric Bypass - Major Differences Between the Two

There are many different procedures available for weight loss, and it can be difficult to decide which is the best option for you. In this blog post, we will discuss two options that people who are looking for bariatric surgery often have, i.e. gastric sleeve vs gastric bypass. These procedures are popular options for weight loss, but they have different benefits and drawbacks. By understanding the differences between these procedures, you can decide which one is right for you.

So, without any delay, let's begin.

Gastric Sleeve Vs Gastric Bypass - Gastric Bypass Surgery Is More Invasive

This is the main difference between the two procedures. Gastric bypass surgery requires dividing the stomach into two sections and attaching the small intestine to the smaller upper section of the stomach. This allows food to bypass the larger lower section of the stomach, reducing how much can be consumed.

Sleeve gastrectomy is less invasive, removing a large portion of the stomach so that only a small stomach sleeve remains. This smaller pouch means patients feel fuller faster and eat less. The procedure also results in a reduction of hormones that stimulate hunger, helping to reduce food cravings.

Gastric Bypass Surgery Results in A Smaller Stomach, While Sleeve Gastrectomy Leaves A Small Sleeve of Stomach

Choosing between gastric sleeve vs bypass, the gastric bypass patients have a smaller upper stomach pouch created during surgery. This means they feel fuller faster and eat less overall. Sleeve gastrectomy patients have a small sleeve of the stomach remaining after the procedure is completed. This small stomach sleeve typically holds about the same amount of food as the pre-surgery stomach.

While both procedures result in smaller stomachs, Dr Feiz says that the main difference is how much of the stomach is removed during surgery. Gastric bypass patients have a much smaller upper stomach pouch, while sleeve gastrectomy patients have a small sleeve of the stomach remaining.

Gastric Bypass Surgery Can Result in Dumping Syndrome, While Sleeve Gastrectomy Does Not

Dumping syndrome is a condition that can occur after gastric bypass surgery. Food moves too quickly from the small upper stomach pouch to the small intestine. This can cause nausea, vomiting, diarrhea, and abdominal pain. Dumping syndrome is a serious complication after gastric bypass surgery, but it is not a risk with sleeve gastrectomy.

Gastric Bypass Vs Sleeve - Gastric Bypass Surgery Is Not Reversible

Gastric bypass surgery is a permanent procedure. Once the stomach is divided, and the small intestine is attached to the smaller upper section of the stomach, this cannot be undone. Sleeve gastrectomy, on the other hand, can be reversed. If a patient decides they want to have the procedure reversed, the stomach can be reconnected.

When it comes to gastric sleeve vs gastric bypass, both surgeries are effective weight loss procedures. There are some key differences between the two, including invasiveness, reversibility, and risks of complications. It is important to discuss all options with our doctor before deciding which procedure is right for you.
