    What is Gastric Bypass?

    Gastric Bypass is one of the common weight loss surgeries performed for those who suffer from obesity. It aims to reduce the size of the stomach and change the way the stomach and small intestine absorb food. Which eventually facilitates the process of losing weight. It’s recommended for people with a BMI of 40 or more.

    The procedure helps lose weight in two mechanisms: restriction and malabsorptive. Restriction in that it limits the food intake and the ability of the stomach to hold food. On the other hand, malabsorptive means reducing the ability of absorbing calories.

    How is Gastric Bypass in Turkey Performed?

    Gastric bypass in Turkey is done by dividing the stomach into two parts: the small upper part, which is known as the “stomach pouch,” and the lower part, which is larger.

    The upper part is then attached to a portion of the small intestine, thus making the food pass from the new gastric pouch directly to the intestine. The operation is done under general anesthesia and through keyhole incisions on the abdominal wall.

    Gastric bypass surgery requires between 2-3 days hospitalization to closely monitor the condition of the patient.

    Gastric Bypass Candidates

    In order to be qualified for a gastric bypass patients must meet the following criteria:

    • To be at least 18 years old. Although in some cases younger patient can also get the surgery if it’s required.
    • Body Mass Index (BMI) of 40 or more.
    • BMI of 35 or more for those with obesity related diseases such as diabetes, hypertension, heart diseases, and sleep apnea.
    • Individuals with multiple attempts to lose weight the traditional way but with no results. 
    • Those who are ready to commit to a new lifestyle in terms of eating and exercising. 

    Mini Gastric Bypass vs Traditional Gastric Bypass

    The mini gastric bypass was created by Dr. Robert Rutledge in 1997 in an attempt to reduce the length of the procedure. And also, to slightly reduce the complications associated with the traditional gastric bypass.

    Although both work in the same manner but below are the main differences between mini and traditional gastric bypass:

    Technique Used

    In terms of how the mini gastric bypass is performed, surgeons create a long narrow tube of the stomach instead of a small pouch. After that they reroute a lower part of the small intestine and connect it with the narrow stomach tube. 

    Unlike the traditional gastric bypass where a small upper pouch of the stomach is created. Then the small intestine is separated and the lower section is attached to the new stomach pouch. And finally, the upper part of the small intestine is connected again to the lower part of it. This allows fluid from the liver and pancreas to be digested.


    The cost of mini gastric bypass is cheaper than the traditional one.


    The time it takes to perform a mini gastric bypass is shorter as compared to the traditional gastric bypass.


    It’s said that the complications associated with gastric bypass are reduced with the mini gastric bypass method.

    What is the Cost of Gastric Bypass in Turkey?

    The average cost of gastric bypass in Turkey ranges between $3500 - $4000. The price varies among hospitals based on the experience of the surgeon, the technique used and location.

    Once the operation is finished you will be required to stay at the hospital for 2-5 days depending on the type of surgery you had. For an open surgery, the duration is longer than the one done laparoscopically. 

    Here are some of the things you should expect after the surgery:

    • During the first few hours after you wake up from the surgery a nurse will closely monitor your vital signs and your overall health. 

    • After you wake up you won't be able to eat anything except drink small sips of water to stay hydrated. A detailed diet after gastric bypass will be discussed below.

    • You will be given some breathing exercises to prevent pneumonia. 

    • The nurse will help you move your legs and wear a compressing stocking to prevent blood clots.
    • You can take a shower 5 days after your surgery but make sure to avoid soaking the incision area and keep it dry. You can wipe the wounds with a wet towel and a mild soap then pat it dry. 
    • Avoid bathing and swimming for 3-4 weeks. 
    • The wound area will be covered with a tape called steri-strip. Your surgeon will tell you how to change it and when it will be removed. 
    • A urine catheter will be attached to your bladder to remove urine. 
    • You may also have a drainage to remove fluids.
    • You can return back to work after 2-3 weeks depending on the nature of your job. If it's physically demanding you might need to wait a bit longer. Check with you surgeon when would be the best time to go back to work.
