Weight Loss Procedures
There are several weight loss options for seriously obese or morbidly obese patients. While all surgical options are effective, not all solutions are the same or offer the same weight loss results. Compare the different types of gastric weight loss procedures below:
Roux-en-Y, or gastric bypass surgery, is the most common procedure for weight loss. With gastric bypass, your surgeon creates a smaller stomach by stapling across the top part of your stomach to create a small pouch about 2-3 ounces in size. The rest of your stomach is completely separated from the pouch but not removed from your body. Your surgeon bypasses parts of your intestine, which results in fewer calories and nutrients being absorbed, changes gut hormones that promote satiety, suppress hunger, and thereby results in weight loss and in some cases reverses type 2 diabetes.
Most often, Roux-en-Y gastric bypass uses a minimally invasive laparoscopic technique; however, a traditional open surgery may be necessary based on your past medical or surgical history.
There are many benefits to sleeve gastrectomy as a surgical weight loss option:
- Hormonal changes suppress hunger and reduce appetite
- Restricts the amount of food that can be consumed
- May lead to conditions that increase energy expenditure
- Typical maintenance of > 50% excess weight loss
Sleeve Gastrectomy (Gastric Sleeve)
Sleeve gastrectomy is a restrictive procedure that removes 80% percent of the stomach. The new stomach is a tubular banana-size pouch that holds much less food than the normal stomach and helps to significantly reduce the amount of food (and thus calories) that can be consumed. Although this surgery drastically reduces the size of the stomach, it will still function normally afterward.
Since sleeve gastrectomy does not involve any bypass of the intestinal tract, it can be performed using a minimally invasive, laparoscopic surgical technique.
Sleeve gastrectomy or gastric sleeve refers to a procedure in which the stomach is divided vertically allowing relatively normal processing of food and nutrients. This procedure is the most commonly performed bariatric surgery and allows you to decrease portion sizes as you feel full sooner and stay full longer. There is significant resolution of comorbid obesity-related diseases post-operatively, like diabetes, hypertension, sleep apnea, etc.
There are many benefits to sleeve gastric bypass as a surgical weight loss option:
- Limits the amount of food your stomach can take in, but does not affect how your stomach functions.
- It reduces how much food you can eat after surgery, but places fewer restrictions on what types of food you can eat, unlike the Roux-en-Y gastric bypass.
- Requires no bypass or re-routing of the food stream.
- Usually involves only an overnight stay in the hospital
- Induces hormonal changes that suppress hunger and reduce appetite.
