Gastric Bypass
Gastric bypass surgery is a type of bariatric surgery. It changes the size and shape of your stomach and small intestine. Gastric bypass surgery is a common treatment for obesity.
Types of Gastric Bypass
There are several types of gastric bypass procedures. All of them bypass (go past or around) the small intestine and some of them reduce stomach size. Your doctor will help determine which type of surgery is best for you based on your medical history and weight loss goals.
Surgeries for weight loss are usually divided into three categories:
-
Restrictive: Limits food intake by reducing stomach size
-
Malabsorptive: Limits food absorption by bypassing parts of the small intestine
-
Combination restrictive and malabsorptive
-
All gastric bypass procedures are malabsorptive. Some are a combination of malabsorptive and restrictive.
Roux-en-Y Gastric Bypass
Roux-en-Y is the most common type of gastric bypass surgery. The procedure involves stapling the stomach to create a small pouch that holds less food. We shape a portion of the small intestine into a "Y." Roux-en-Y is:
Biliopancreatic Diversion Gastric Bypass
Biliopancreatic diversion (BPD) is a less common procedure. It is more complicated than Roux-en-Y gastric bypass. Biliopancreatic diversion is different from Roux-en-Y:
-Malabsorptive (limits food absorption)
-Restrictive (limits food intake)
-Highly successful for weight loss
-It is primarily malabsorptive (limits food absorption)
-It Involves the removal of part of the lower stomach
-It is typically reserved for patients that are severely obese, with a body mass index (BMI) greater than 50.
SADI-S (Single Anastomosis Duodeno-Ileal bypass with Sleeve gastrectomy)
- No endoscopy or anesthesia required
- Swallowed as a capsule, then filled with fluid through a thin catheter
- Balloon automatically empties and passes naturally after ~16 weeks
- Shorter duration but very low-risk and convenient
- Suitable for busy patients, or those who prefer a fully non-invasive approach
Mini Gastric Bypass
Mini gastric bypass (MGB), or one anastomosis gastric bypass (OAGB), is a laparoscopic weight-loss surgery that combines a small, tube-shaped stomach pouch with bypassing a portion of the small intestine.
It differs from traditional gastric bypass by using one intestinal connection. Both surgeries, reduce stomach size and limit calorie.
-It restricts food intake; the procedure creates a small, tube-like stomach
-It reduces food absorption; your stomach connects to the middle of your small intestine. It bypasses the first part of your intestine.

-Those with a general health condition that can carry the risks of surgery: Individuals whose heart, liver or other systemic diseases are under control may be suitable candidates.
How Long Does Gastric Bypass Surgery Take?
Gastric bypass surgery usually lasts 2 to 4 hours. This can change based on how complex the surgery is and the techniques used.
At what age can gastric bypass surgery be performed?
Gastric bypass surgery, or stomach reduction surgery, is performed on people between the ages of 18 and 65. To be a suitable candidate for gastric surgery. For people under the age of 18, the degree of obesity and the presence of the diseases listed above are important, and parental approval is required as well as a physician's decision. For people over 65 years of age, the health status and the necessity of surgery (the person's weight-related problems and problems they experience) are evaluated.
