Gastric Sleeve vs Gastric Bypass

Weight loss surgical options have increased significantly within the past few decades. Patients now can consider choices such as Gastric Bypass, the Lap-Band, Intragastric Balloons, or the Gastric Sleeve procedure. If you are considering a weight loss procedure, deciding which procedure is right for you can be very daunting. Reviewing the risks and benefits of the Gastric Sleeve vs.Gastric Bypass might be a good start in identifying when to choose Gastric Sleeve surgery in Dallas.

These two procedures may share similarities but are quite different. Here is a side by side comparison for the Gastric Sleeve and the Gastric Bypass.

Gastric Bypass

With this surgery, the size of your stomach is reduced to about the circumference of a walnut. The surgeon will use staples to create a smaller upper portion of the stomach, separating it from a larger lower portion. The small section is where the food you ingest will begin to be digested. Because it is such a small space, holding around 1 ounce, it helps you intake less food, and remain fuller for a longer period of time. This pouch will be routed to your small intestine, effectively “bypassing” the large intestine, thus inhibiting your body’s ability to store or absorb calories. Because of this, your body will burn stored fat as energy.

Gastric Sleeve

With this option, the side of your stomach that balloons out is removed. That balloon section is the larger portion of your stomach which has the potential to hold the most food. Removing it leaves a “sleeve” that is roughly the size and shape of a banana. Similar to a bypass, you remain fuller longer, can eat only small amounts of food and will utilize stored fat for energy. The biggest variance from a Gastric Bypass is that there is no re-routing to the small intestine as the food still travels through the large intestine, using the normal digestive process.

How much weight will you lose? On average, patients lose:

Gastric Bypass

60-80% within the 1st year

Sleeve Gastrectomy

50-70% within the first 2 years

Understand that the most important part of any weight loss procedure is your commitment to making it happen. Having realistic expectations, following a healthy diet, including exercise in your daily regimen and changing your outlook on food and lifestyle will either increase or hinder the success of any surgical option that you choose.

Benefits and Risks of Both

While Gastric Bypass has the following benefits:

  • A longer history with proven and recorded success
  • Bypassing the large intestine which helps prevent absorption of calories
  • The Dumping Syndrome side effect, which helps condition you to eat less sugar filled or fatty food

The Gastric Sleeve also has its own benefits:

  • The portion of the stomach that is removed is where the hunger hormone “ghrelin” is created, thereby causing a reduction of hunger pangs
  • Losing weight slowly causes less sagging of skin because the skin adjusts at a less rapid rate

The two surgeries have similar risks including bleeding, blood clotting, infections and leaking of the surgical site. In addition, both surgeries are unable to be reversed. Gastric Bypass has a few other drawbacks which can include the potential of a bowel obstruction, ulcers, or acid reflux.

In general, while each surgery should be reviewed according to a patient’s goals and individual considerations, such as contraindications of certain medications, overall health, and eating habits, Gastric Sleeve is usually less expensive but may not be covered by insurance. It is also believed to have fewer risks as it is less invasive than Gastric Bypass.

The decision of which option to choose should be made by you and your doctor. Relying on an experienced and knowledgeable surgeon, like those at Expert surgical, is important to the safety and success of your weight loss surgery.
