Roux-en-Y gastric bypass (RYGB) is a type of weight-loss surgery. Weight-loss surgery is also called bariatric surgery. It’s often done as a laparoscopic surgery, with small incisions in the abdomen. The Roux-en-Y gastric bypass procedure involves creating a stomach pouch out of a small portion of the stomach and attaching it directly to the small intestine, bypassing a large part of the stomach and duodenum. Not only is the stomach pouch too small to hold large amounts of food, but by skipping the duodenum, fat absorption is substantially reduced.

Benefits of Gastric Bypass Surgery

  • It is applied laparoscopically, thus, this way accelerates the wound healing of the patient.
  • Food absorption is reduced by disabling the first 150-200 cm of the small intestine.
  • Hormonal changes (hunger hormone-ghrelin) level decreases.
  • Most people lose 10 to 15 pounds in the first month after surgery.
  • 75% of excess weight is lost within 1 year after the operation.
  • Since the stomach is reduced after gastric bypass, patients start to feel full more quickly despite eating less.
  • The risk of joint disorders, sleep apnea, high blood pressure, high cholesterol and heart diseases that may occur due to overweight, especially diabetes, is reduced.

    I had surgery February 3, 2023. From the moment I landed in Istanbul until the time I left, I was given 5 star treatment. My experience, like so many others was amazing! Everything was explained to me before having RNY bypass. I knew what to expect because I have done my own research on it. Nothing can prepare you for the gas pain after waking up from surgery but they got my pain under control and within 4 hours of surgery I was up and walking the corridor. If I wasn’t sleeping, I was walking. It made recovery so much better and it helped kill the time and boredom of being in a hospital. Post op treatment was beyond excellent. Was given plenty of fluids and protein via IV. Once the drain was pulled, I felt like a new woman. Full of energy and ready to go! The hotel accommodations exceeded my expectations. My friend was given amazing breakfasts and their dinner menu at the local restaurant smelled amazing. Everything was very affordable and having a mall across the street to be able to walk and shop was so easy. My only regret was that I didn’t have this done sooner. I’m 7 weeks post op and I’m down 50 pounds since surgery and 75 total pounds down since Christmas. Thank you to the entire team who helped me with my journey. I will never forget it. And I will always sing your praises to anyone who needs the help like I did.

    I honestly enjoyed every bit of my journey with you, I was well looked after by a star team. I will personally like to thank luna she was my travel advisor, she was there from the beginning till the end, she helped organise everything and made this a smooth and easy process considering I am doing an surgery and it can get overwhelming at times, she was always there for me. I would like to thank my doctor for the successful operation without any side effects and always checking in with me to make sure I was well on my way for a full recovery. The team of nurses are honestly the loveliest people. I can not recommend this company enough 🙂

    At first I was very nervous but at the same time I was excited to start my weight loss journey, the staff and doctors were very helpful and I trusted them with my surgery thankyou once again to Letsmedi for the best weight loss surgery experience they are one of the best team for weight loss surgery in Turkey

    My Gastric Sleeve Surgery had been the Best decision I made!

    Finally 1 month after my gastric sleeve surgery with the brilliant Assoc Prof. Abudullah Sisik and his amazing team at Dr. HE Clinic.
    In my first month so far I have lost 15 Kilos.
    I definitely made the right decision trusting Letsmedi with my Gastric surgery.
    Before I travelled to Istanbul my coordinator Luna helped me with all my question she even arranged for a video conference call with Dr. ABDULLAH Sisik To asked him and clarify any doubts that I might have, because my overweight was killing me by affecting my quality of sleep, my joints were in constant pain, I was struggling to work with all my overweight, was suffering from high blood pressure and pains in the body.
    Once every doubt was cleared she helped me with my travelling booking my VIP picked up from the airport (wonderful crew also) and my stay at a wonderful 4 Star hotel (Hampton by Hilton Istanbul Kurtkoy).
    I had some pain and sickness after my op the first day but the nurses made sure I got painkillers and anti sickness meds through my drip and I was out of bed within 6 hours after surgery walking to help get rid of my gas pain.

    The nurses were very human and kind and knew what you needed when asking them.
    With the help of walking and the breathing exercises my gas pain was completely gone by day 4.
    You get woken early in the morning for blood tests and blood pressure check.

    On the 2nd and 3rd day the dietitians will teach and give you different flavours of shakes for your next 2 week journey.
    After this you continue
    recuperating then you go to your hotel for a few days then more check ups for a clean bill to go back to your home country on this day the same VIP crew comes and picks you up to drop you at the airport to take your flight with the same VIP treatment. Then you are ready to start a new and healthier life!
    My only regret is that I should’ve done my gastric surgery before; not waited for such a long time suffering with all the complications that the overweight brought to my life.

    It will be a month tomorrow since my operation with Dr Abdullah. From the moment I reached out for information until now the service has been amazing! The surgery itself was great and all the care team in the hospital were unreal. If you are looking into this bariatric surgery then I would 110% recommend Letsmedi. They are super and so all the ball, you can ask a question at midnight and it won’t take long for a rely! They really are outstanding. Special thanks to Dr Abdullah and the lovely Luna for answering all of my silly questions.

What can I expect in terms of wounds and scarring after bariatric surgery Rebecca asked on 12/02/2021

Since the incisions made during the surgery are very small, minimal scarring will occur. However, scar formation may show individual differences
