Gastric Bypass

Gastric bypass surgery, also known as Roux-en-Y gastric bypass, is a transformative bariatric procedure designed to facilitate significant weight loss by altering the digestive system. This surgery not only restricts food intake by creating a smaller stomach pouch but also changes the way food is absorbed by bypassing a portion of the small intestine. As a result, patients experience an early sense of fullness alongside a reduction in the number of calories absorbed by the body. Ideal for individuals struggling with obesity and related health conditions, gastric bypass offers a profound impact on weight management and can lead to substantial improvements in overall health and quality of life when combined with lifestyle changes.

What is Gastric Bypass?

Gastric bypass, formally known as Roux-en-Y Gastric Bypass (RYGB), is a highly effective weight loss surgery that has become a cornerstone procedure in bariatric medicine. It involves creating a small pouch from the stomach and connecting it directly to the small intestine, effectively bypassing a large part of the stomach and a segment of the small intestine. This not only severely limits the amount of food that can be consumed at any one time, promoting a feeling of fullness with less food, but also reduces the number of nutrients and calories absorbed by the body. 

Gastric Bypass Basics: Gastric bypass surgery, a substantial step in the battle against obesity, involves restructuring the digestive system to facilitate weight loss. By creating a smaller stomach pouch, the procedure ensures a reduced food intake, while bypassing part of the small intestine means fewer calories are absorbed. This dual approach has proven effective for long-term weight management and is a recommended option for those with severe obesity or obesity-related health issues.

Lifestyle Impact: Undergoing gastric bypass surgery is more than a medical procedure; it's a commitment to a new way of life. Post-surgery, patients will experience significant changes in their eating habits, portion sizes, and overall relationship with food. To maintain the benefits of the surgery, patients must adhere to nutritional guidelines, engage in regular physical activity, and attend follow-up appointments to monitor their health and progress.

What do the experts say about this operation?

We're with you at every step of the operation.

They underscore the necessity for patients to be fully aware of the lifestyle and dietary commitments essential for sustaining weight loss after surgery. In this section, we offer comprehensive advice to prepare you for your gastric bypass journey, laying out the crucial steps to navigate potential obstacles, and organizing all pertinent arrangements to ensure a smooth process throughout your treatment in Turkey. With professional insights at your fingertips, you can embark on the gastric bypass path with assurance and a clear understanding of the journey ahead.

Your journey towards a healthier lifestyle with gastric bypass surgery starts with a thorough consultation at our state-of-the-art clinic in İzmir. Typically, this initial meeting lasts around 30 minutes.

During this consultation, you will meet with our experienced bariatric surgeon, Dr. Serdar Civelek. This is a perfect opportunity to discuss every detail pertaining to gastric bypass surgery. You are encouraged to come prepared with any questions or concerns regarding the operation. Dr. Civelek will assess your health, understand your weight loss objectives, and determine the most suitable approach tailored to you. Furthermore, Dr. Civelek will provide comprehensive information about the surgery and address all your queries to ensure you feel well-informed and comfortable with the decision to proceed.

To optimize your gastric bypass surgery results, we recommend the following pre-operative guidelines:

- Stop smoking: Cease smoking at least six weeks before the surgery to improve healing and recovery.
- Limit alcohol intake: Reduce alcohol consumption leading up to the surgery and abstain completely on the day of and several days before the operation. After surgery, avoid alcohol until you have finished any prescribed medications.
- Get ready for anesthesia: Gastric bypass surgery requires general anesthesia, which means you must fast for at least 12 hours before the operation. Avoid any food or drinks during this fasting period.

On the day of your surgery, our transport service will pick you up from your accommodation and bring you to our clinic. You will have a final meeting with Dr. Civelek and the medical team to address any last-minute questions and go over the surgical plan once again.

The gastric bypass operation will be performed using minimally invasive techniques, and after the surgery, you will be closely monitored for a short period in the recovery room before being transferred to your hospital room with detailed post-operative care instructions.

Following the procedure, it's normal to experience some drowsiness due to the anesthesia, but this will wear off after a brief period of rest. Upon discharge, our medical team will provide you with a comprehensive guide on the dietary stages you should follow and how to manage any potential discomfort.

Post-surgery, it's imperative to take any medications exactly as prescribed and adhere strictly to the diet plan provided by our dietitian. You might initially feel some fatigue, but any discomfort can generally be handled with the recommended medication.

As part of your recovery, our team will maintain regular contact to monitor your progress and may ask for photos to assess your healing. We will also set up virtual consultations to keep Dr. Civelek updated on your recovery and offer any additional support you might require.

What Is Gastric Bypass?

Gastric bypass is a type of bariatric surgical procedure used to treat obesity. In this procedure, the stomach and intestines are rearranged to reduce food intake and digestion, thereby promoting weight loss. Gastric bypass surgery is typically used to reduce or control health problems associated with obesity. In this procedure, the stomach is reduced in size and the intestines are rearranged, resulting in the individual consuming less food and decreased absorption of nutrients. This accelerates weight loss and may reduce or eliminate health issues associated with obesity.

Why Do People Get Gastric Bypass Surgery?

  • Managing Obesity: Gastric bypass surgery can be an effective option for managing obesity and losing weight. This surgery reduces food intake through anatomical changes in the stomach and intestines, promoting weight loss.
  • Improving Health Issues: Obesity can lead to various health problems, including type 2 diabetes, hypertension, sleep apnea, and heart disease. Gastric bypass surgery can be used to improve or eliminate these health issues associated with weight loss.
  • Failure with Diet and Exercise: Some individuals may not achieve the desired results with traditional weight loss methods such as diet and exercise. In such cases, gastric bypass surgery may be considered to accelerate weight loss.
  • Enhancing Quality of Life: Physical mobility can be restricted due to obesity, making daily activities more challenging. Gastric bypass surgery can improve quality of life by increasing energy levels and freedom of movement along with weight loss.
  • Long-Term Health Goals: Gastric bypass surgery can serve as a starting point for individuals aiming to achieve long-term health goals. The surgery can help individuals adopt healthy lifestyle changes and maintain a healthy weight over time.

What Are The Types Of Gastric Balloon Surgery?

  • Roux-en-Y Gastric Bypass: In this method, the stomach is reduced in size and reshaped into a smaller tube. Then, the stomach is not directly connected to the intestines; a small stomach outlet is created by joining the upper part of the intestines. This allows food to pass directly from a part of the stomach to the intestines, thereby reducing nutrient absorption.
  • Biliopancreatic Diversion (BPD): In this method, the stomach is reduced in size and reshaped into a smaller tube. Then, the stomach is connected to the intestines, and a portion of the small intestine is cut to reduce the length of the intestines through which food passes. This also decreases nutrient absorption.
  • Biliopancreatic Diversion with Duodenal Switch (BPD-DS): This method is similar to BPD, but the intestines are corrected. A portion of the small intestine is cut and rearranged, shortening the length of the intestines through which food passes and reducing absorption.

Gastric bypass surgery is typically performed using laparoscopic surgery (closed surgery) method. In this method, small incisions are made, and the operation is performed using a camera and surgical instruments. Laparoscopic surgery is less invasive and has a shorter recovery time compared to traditional open surgery.

Since each patient's condition is different, the decision on which method to use is made jointly by the surgeon and the patient. This decision is based on factors such as the patient's body mass index, health status, and response to surgery.
