What is Gastric Bypass (Roux-En-Y)?
The Roux-en-Y gastric bypass is one of the most commonly performed types of bariatric surgery. It works by both reducing the stomach size and altering the digestive tract to limit calorie and nutrient absorption. This dual mechanism makes it highly effective for long-term weight management.
How Roux-En-Y Gastric Bypass Works
Roux-en-Y gastric bypass (RYGB) is a bariatric surgery that aids in weight loss by altering the digestive system’s structure and function. During the procedure, a small stomach pouch is created, approximately 15–30 milliliters in size, by dividing the upper portion of the stomach. This pouch is then connected directly to the small intestine, bypassing the larger part of the stomach and the initial segment of the small intestine. This modification restricts food intake and decreases nutrient absorption, leading to significant weight loss. Patients often experience improvements in obesity-related conditions such as type 2 diabetes and hypertension.
- Stomach Reduction: The stomach is divided into a small pouch (approximately the size of an egg), restricting the amount of food that can be consumed.
- Intestinal Rerouting: The small intestine is restructured to bypass a portion of the digestive system, reducing calorie and nutrient absorption.
- Hormonal Changes: The procedure alters gut hormones, which helps decrease appetite and improve blood sugar control.
Who is a Suitable Candidate for Gastric Bypass Surgery?
Gastric bypass Turkey is a significant intervention for individuals struggling with severe obesity and related health conditions. Suitable candidates typically include:
• Individuals with a Body Mass Index (BMI) of 40 or higher: This classification indicates extreme obesity.
• Individuals with a BMI between 35 and 39.9: Candidates in this range should have serious weight-related health issues such as type 2 diabetes, high blood pressure, or severe sleep apnea.
• Individuals with a BMI between 30 and 34.9: In certain cases, those with type 2 diabetes that is difficult to control with medical treatments and lifestyle changes may be considered for surgery.
Beyond BMI, candidates should have attempted other weight loss methods without sustained success and be prepared to commit to long-term lifestyle changes post-surgery. A comprehensive evaluation by a healthcare team is essential to determine suitability for the procedure.

Gastric Sleeve vs Gastric Bypass
Gastric sleeve surgery involves permanently removing approximately 80% of the stomach, leaving a narrow tube-shaped stomach about the size of a banana. This significantly reduces hunger by decreasing the production of ghrelin, known as the hunger hormone, thus restricting food intake and promoting substantial weight loss. Gastric sleeve patients typically lose between 60% to 70% of excess body weight within the first 18 months post-op. While it’s generally less complex and has lower surgical risks than gastric bypass surgery, it does carry potential drawbacks, such as increased risk for gastroesophageal reflux disease (GERD). Ideal candidates for gastric sleeve surgery are individuals looking for an effective, yet comparatively simpler bariatric procedure with fewer nutritional complications.
Gastric bypass surgery (Roux-en-Y) is a more intricate bariatric procedure where a small stomach pouch is created, bypassing most of the stomach and the upper part of the small intestine. This dual-action procedure significantly limits calorie absorption and reduces hunger, often resulting in rapid weight loss of up to 80% of excess body weight within 12 to 18 months. Gastric bypass surgery is particularly beneficial for patients struggling with obesity-related conditions like type 2 diabetes, hypertension, and sleep apnea, frequently leading to dramatic health improvements soon after surgery. However, this procedure has higher risks, including nutrient deficiencies and dumping syndrome. Individuals considering gastric bypass surgery should thoroughly evaluate their health needs and discuss long-term lifestyle commitments with their bariatric surgeon.
Gastric Band vs Gastric Bypass
When comparing gastric band and gastric bypass surgery, it’s important to consider their differences and suitability carefully. Gastric bypass surgery, specifically the Roux-en-Y procedure, involves creating a small stomach pouch and rerouting the small intestine, significantly reducing calorie absorption and promoting rapid weight loss. This surgery typically results in losing up to 80% of excess weight and effectively improves obesity-related conditions such as type 2 diabetes and hypertension. Conversely, gastric band surgery is less invasive, involving an adjustable silicone band placed around the stomach’s upper portion, restricting food intake without permanent digestive changes. Although gastric banding is reversible and carries fewer surgical risks, weight loss occurs more gradually and usually requires ongoing adjustments. Gastric bypass surgery is often recommended for patients with severe obesity or significant metabolic health issues, while gastric band surgery suits those seeking a less invasive and reversible bariatric solution.

Preparing for Roux-En-Y Gastric Bypass Surgery
Proper preparation is critical for a successful gastric bypass in Turkey. Patients must adhere to specific guidelines and undergo detailed evaluations to ensure optimal outcomes.
Pre-Operative Tests and Evaluations
Before undergoing Roux-en-Y gastric bypass surgery, patients are required to complete a series of tests and consultations, including:
- Medical History and Physical Examination: To assess overall health and identify potential risks.
- Diagnostic Tests: Blood work, imaging (X-rays or ultrasounds), and an ECG may be performed to evaluate internal health.
- Endoscopic Evaluation: To examine the stomach and ensure there are no abnormalities or ulcers.
- Psychological Assessment: To confirm the patient’s readiness for the surgery and the necessary lifestyle changes afterward.
Dietary and Lifestyle Changes Required Before Surgery
In preparation for surgery, patients are advised to follow a pre-operative plan designed to reduce surgical risks and enhance recovery:
- Liver-Shrinking Diet: A high-protein, low-carbohydrate diet is typically required for 1-2 weeks before the procedure. This helps reduce liver size, making the surgery safer.

The Gastric Bypass Procedure
Understanding the steps involved in Roux-en-Y gastric bypass surgery can help patients feel more at ease about the process.
Step-by-Step Overview of the Gastric Bypass Surgery
Gastric bypass surgery, specifically the Roux-en-Y gastric bypass, is a well-established procedure for significant weight loss and improvement of obesity-related conditions. Here’s a step-by-step overview of the process:
- Preoperative Preparation:
• Medical Evaluations: Comprehensive assessments, including blood tests, imaging studies, and cardiac evaluations, are conducted to ensure the patient is fit for surgery.
• Nutritional Counseling: Patients receive guidance on dietary changes required before and after surgery to facilitate a smooth transition and promote healing.
• Psychological Assessment: An evaluation to confirm the patient’s readiness to adhere to postoperative lifestyle changes.
• Pre-Surgery Instructions: Patients may be advised to follow a specific diet and cease certain medications leading up to the surgery. - Anesthesia and Incision:
• Anesthesia: General anesthesia is administered to ensure the patient remains unconscious and pain-free during the operation.
• Incision Method: The surgery is typically performed laparoscopically, involving several small abdominal incisions through which specialized instruments and a camera are inserted. - Creation of the Stomach Pouch:
• The surgeon divides the upper portion of the stomach, creating a small pouch approximately the size of a walnut (about 1 ounce or 30 milliliters in volume). This pouch will serve as the new, reduced stomach, limiting food intake. - Rerouting the Small Intestine:
• The small intestine is divided, and the lower section is connected to the newly formed stomach pouch. This allows food to bypass the majority of the stomach and the upper portion of the small intestine (duodenum), reducing calorie and nutrient absorption. - Reconnecting the Small Intestine:
• The bypassed section of the small intestine is reconnected further along, allowing digestive enzymes and bile from the stomach and pancreas to combine with the food consumed, aiding digestion. - Closing Incisions:
• After confirming the integrity of the newly formed connections and ensuring there are no leaks, the surgeon closes the incisions with sutures or staples. - Postoperative Care:
• Hospital Stay: Patients typically remain in the hospital for 2 to 3 days.
• Dietary Progression: The diet progresses from clear liquids to pureed foods, and eventually to solid foods over several weeks, as guided by a nutritionist.
• Follow-Up Appointments: Regular check-ups are scheduled to monitor weight loss, nutritional intake, and overall health.
This structured approach ensures that gastric bypass surgery is performed safely and effectively, providing patients with the tools needed for significant weight loss and improved health outcomes.
