Advanced, Minimally Invasive Gastric Bypass Surgery for Safe, Effective & Long-Term Weight Loss
Gastric Bypass (Roux-en-Y) at Memorial Hospital Turkey is one of the most successful bariatric procedures for patients struggling with severe obesity, chronic weight-related diseases, or long-term failure with diet and medications. Performed using advanced laparoscopic and robotic techniques, R-YGB helps patients achieve 60–80% excess weight loss, improves metabolic health, regulates blood sugar, reduces hunger hormones, and offers a long-term solution to obesity.
Memorial’s expert bariatric surgery team evaluates each patient thoroughly and provides a customized treatment plan supported by endocrinology, psychiatry, dietetics, and long-term follow-up to ensure safe and sustainable weight loss.
🩺 What Is Gastric Bypass (R-YGB)?
Gastric Bypass (Roux-en-Y) is a bariatric surgery that reduces stomach size to 25–30 ml and reroutes part of the small intestine. This creates a smaller stomach pouch and bypasses a segment of the intestine, helping patients eat less while absorbing fewer calories.

This dual mechanism results in:
- Rapid satiety
- Reduced calorie absorption
- Hormonal changes that lower hunger and improve blood sugar
- Significant and long-lasting weight loss
- It is reversible, unlike sleeve gastrectomy.
How Is Gastric Bypass Performed?
- Performed laparoscopically or robotically
- 4–6 small incisions (1 cm each)
- 95% of the stomach bypassed
- Small stomach pouch created
- Small intestine rerouted and connected to the pouch
- Food bypasses the duodenum, reducing absorption
🩺 Types of Gastric Bypass at Memorial Hospital
- Roux-en-Y Gastric Bypass (R-YGB)
- Creates a 25–30 cc stomach pouch
- Bypasses the duodenum and part of the small intestine
- Strong metabolic effect on Type 2 diabetes
- Gold-standard method used globally
- Mini Gastric Bypass (MGB)
- Creates a tube-shaped pouch
- Only one intestinal connection
- Slightly easier technique, similar results
- Same weight-loss mechanism
Both procedures deliver excellent long-term weight-loss outcomes.
