People suffering from chronic or severe obesity now have a variety of weight loss surgery options at their disposal to help them accomplish life-changing weight loss. Gastric sleeve surgeries and gastric bypass surgeries could help you achieve significant weight loss because they both allow patients to feel full after eating less food.
This article will compare the similarities and differences between these two weight loss procedures, but there is simply no substitute for having an informed discussion with your doctor to find the best option for your situation and your goals.
A Laparoscopic Sleeve Gastrectomy, which is also called gastric sleeve surgery, involves permanently removing the left part of the stomach in order to help patients lose weight through caloric restriction, leaving the reduced stomach with a more sleeve-like shape. This method affects the body’s normal satiety mechanism, helping gastric sleeve patients to feel full with a reduced appetite. Gastric sleeve patients may also experience a reduction of hunger-related hormone production.
The sleeve gastrectomy surgery takes under an hour with patients discharged after 1-2 days where they can return to work after 2-4 weeks.
The Laparoscopic Roux-en-Y Gastric Bypass is a form of gastric bypass surgery. As the name implies, the purpose of this procedure is to cause food to bypass a majority of the stomach and a small part of the intestine, however, no organs are removed. The following is what will occur during the surgery:
This gastric bypass procedure takes an hour and a half, and it has a two-day recovery period in the clinic. Once patients are discharged, they are advised to remain at home for two weeks before returning to their job.
Patients can also undergo a Mini Gastric Bypass (MGB) where only one connection is made between the stomach and intestine compared to the Laparoscopic Roux-en-Y Gastric Bypass. The upper stomach part is similar to a “⅔ sleeve gastrectomy. The first part of the intestine is attached to the small gastric pouch created by the bariatric surgeon and placed at the bottom of the new sleeve.
With only one connection made to the stomach and intestine, the surgery takes less than an hour and doesn’t require as much anesthesia.The MGB provides similar weight loss results to the Laparoscopic Roux-en-Y Gastric Bypass.
Both types of gastric bypasses use gastric reduction and intestinal hyposorption to help patients achieve weight loss. Vitamin and mineral supplementation are required after the surgery.
Both gastric bypass and gastric sleeve procedures are performed through laparoscopic surgery, which is a minimally invasive technique that uses a small camera in order to make as few incisions as possible.
The gastric sleeve procedure is usually performed on high-risk patients in two steps before intestinal surgery at a later time. It’s generally less invasive with fewer risks than many other weight-loss surgeries; as a result, it’s often used as a first step in surgical weight-loss treatments.
On average, gastric sleeve patients experience a reduction in excess body weight within one year, which can be between 55-75%. Gastric bypass patients lose between 50-80% of excess body weight within 12-18 months. Both procedures have similar weight loss results after 5 years in randomized studies.
Gastric sleeve surgery does not affect the small intestine while a gastric bypass does. Digestion and absorption are not affected in gastric sleeve patients, so their eating habits don’t need to be radically changed as they would be after a gastric bypass.
Side effects vary, gastric sleeve patients may have more reflux of acid, while gastric bypass patients have more risk of bowel obstruction.
For patients who undergo either weight loss procedure, there are similar requirements for exercise and diet regimes following the procedure to maximize weight loss. While both procedures help the patient feel full more quickly, the gastric bypass also reduces vitamin and mineral absorption. Consequently, gastric bypass patients have stricter supplementation and vitamin level monitoring.
Both gastric sleeve surgery and gastric bypass surgery reduce a patient’s risk of obesity-related conditions, including:
Now that you know the differences and similarities between the two procedures, you probably want to know which one you would have to undergo.
The surgeon will determine whether a patient needs gastric sleeve surgery or gastric bypass surgery based on their particular situation. They will review many factors, such as the patient’s body mass index (BMI), medical history and health conditions.
If you’re having trouble losing weight because of chronic or severe obesity, a bariatric procedure could help you bring about life-changing weight loss.
