About the clinic

Gastric sleeve surgery at Booking Surgery by Global Health Services in Istanbul, Turkey, typically runs between $2,700 and $4,800. This procedure helps patients lose significant weight by removing about 80% of the stomach using laparoscopic methods. The clinic is JCI-accredited and maintains a high success rate, with no fatalities reported in over 16,000 cases.

Surgical Expertise and Results

The surgical team is led by Assoc. Prof. Dr. Ali Tardu and Assoc. Prof. Dr. M. Kağan Katar. Together, these specialists have performed 30,000+ bariatric procedures. During the one-hour surgery, the doctor makes four or five small incisions to create a banana-shaped sleeve. This change reduces the hunger hormone, Ghrelin, helping patients feel less hungry. Most people lose 60-70% of their excess weight within the first year. Health conditions like type 2 diabetes and sleep apnea often show improvement within the first month after the operation.

Treatment Process and Recovery

Patients stay in Istanbul for about 8 days to complete the treatment and initial recovery. The process includes three nights in a private hospital room and four to five nights in a luxury hotel. Recovery starts quickly, and patients are encouraged to walk within four hours of surgery. The clinic provides specific care steps to help with healing:

Phase 1: Liquid diet for three weeks after the procedure.
Phase 2: Soft or pureed foods for the following three weeks.
Support: Access to a nutritionist for 12 months to manage dietary changes.
Medication: Prescribed blood thinners, stomach protectors, and compression socks to prevent complications.

Package Inclusions

The all-inclusive package at Booking Surgery covers all medical and logistical needs. It starts with a health screening including blood work, EKG, and lung X-rays. The price also covers the surgical procedure, anesthesia, and consultations with specialists in internal medicine and dietetics. For convenience, VIP transfers between the airport, hotel, and hospital are included. The clinic holds an International Health Tourism Authorization Certificate from the Turkish government, ensuring they follow official safety standards. You can request a consultation to receive a personalized treatment plan.

Booking Surgery by Global Health Services: more details about the clinic

Turkey, Istanbul

Booking Surgery by Global Health Services is a Turkey-based health tourism organization located in Istanbul. The company coordinates specialized medical care for international patients across four medical facilities. It originated as an international patient department in 2012 and became a separate entity in 2021. With over 13 years of experience, the team works through a network of partnered hospitals to provide surgical and restorative treatments.

Accreditations and Achievements

Booking Surgery holds JCI and ISAPS accreditations, meeting international safety and quality standards. The organization is also accredited by the Ministry of Health of the Republic of Turkey. It only partners with facilities that have a Health Tourism Authorization Certificate. The network includes 13+ physicians, with specialists who have over 15 years of experience. Surgeons in the bariatric program have collectively performed over 20,000 weight loss procedures.

Bariatric and Metabolic Surgery

The clinic focuses on laparoscopic techniques to treat obesity and related metabolic conditions. Surgeons use small-incision methods, so recovery is faster and routine drains are rarely needed. The bariatric program treats patients with a BMI of at least 28. Patients often see improvements in Type 2 Diabetes and high blood pressure within the first month. Most lose up to 90% of excess weight within one year by following nutritional guidelines.

Available weight loss procedures include:

Gastric Sleeve (Sleeve Gastrectomy)
Roux-en-Y Gastric Bypass
Mini Gastric Bypass
Revision Bariatric Surgery
Metabolic surgery for Type 2 Diabetes

Non-surgical slimming options are available for patients with a BMI between 28 and 30. The clinic uses silicone Intra-Gastric Balloons inflated with saline. Options include 6-month and 12-month models, such as Orbera and Medsil. The Elipse Balloon is also offered – a swallowable capsule that doesn't require endoscopy.

Plastic and Reconstructive Surgery

Booking Surgery manages a full aesthetic pathway for facial and body transformations. Care coordinators support patients from the initial inquiry through 12 months post-procedure. The surgical team includes Dr. Malik Abaci, who has over 15 years of experience. The clinic maintains a revision policy for issues occurring within the first year.

The plastic surgery department performs several specialized procedures:

Facelift variants including full, mid-face, and endoscopic mini-lifts
Body contouring such as liposuction and tummy tucks
Facial aesthetics including rhinoplasty and blepharoplasty
Breast surgery and 360° Fleur-de-Lis body lifts
Bichectomy (Buccal Fat Removal) to sharpen facial lines

Specialized facial procedures like the Lip Lift take about one hour. Surgeons also perform Bichectomy under general or local anesthesia to enhance cheekbone definition. Post-operative care includes 24/7 support and guidance on managing initial swelling.

Cosmetic Dentistry and Other Specialties

Restorative dental services are delivered through a specialized Dental Clinic within the network. The team provides Hollywood Smile planning, including gum contouring and placement of crowns or veneers. Options include zirconium crowns, E-max crowns, and laminate veneers. The clinic also coordinates keratoplasty (cornea transplantation) for patients with corneal damage or eye injuries.

International Patient Services

Booking Surgery provides all-inclusive medical travel packages for international visitors. Multilingual coordinators handle scheduling, medical evaluations, and 24/7 support in the patient's language. VIP airport transfers are included for all patients. Accommodations are arranged in partnered hotels or private hospital rooms.

The standard hospital stay for bariatric patients is three nights and four days. Patients may bring a companion at no extra cost, and free daily meals are provided. Post-operative care includes follow-ups until the patient is ready to fly home. The team monitors recovery milestones – for example, walking within two hours after weight loss surgery.

I recently had surgery with Dr Emin at the beginning of April through booking surgery and I have to say they’ve been brilliant, from the very beginning nothing has been too much for them. Very helpful, understanding and professional. The hospital staff at Yasam were just the best, such kind, caring people! My surgeon has done an amazing job, very neat scars and I’ve been told by professionals in the uk that my belly button is one of the best they’ve seen after abdominoplasty (only been 3 weeks) Also I have to give my coordinator Bruce a shout out for putting up with me haha, I have had one million questions, panicked about stuff, changed my mind etc and he’s been really good, nothing has been too much for him and he’s answered all my questions and concerns with no problems. Even after my surgery now I’m still in contact with him checking on my healing etc. I’d highly recommend this company for sure! 🫶🏼

Hi, on Thursday I was operated on at this clinic for recognition of someone else’s recommendation. I’m from Barcelona. I had gastric sleeve surgery and I have to say I went into the operation with total panic. Everything was a success—my first night was horrible: I went through a lot with vomiting and stomach pain. But the next day, everything started to improve. I have to say I left happy with everything. When I returned to Spain, in the car I was given a translator named Denis who speaks Spanish better than many of the people there in this clinic—it’s more than English or other languages, but Denis treated us incredibly well. He helped us at the airport with everything, making everything faster so I wouldn’t have to suffer for so many hours. I mean, Denis is a sweetheart. And everything was great. I bought everything there: the vitamins, the sachets, everything. They give it all to you, and you have options for what to buy. Now I’m in the liquid phase—I’ve been on it for 4 days. But I’m doing super well: I have lots of energy and I’m feeling great. The stitches on my belly will fall off on their own and everything is healing well, and I recommend it. I’d been thinking about it for more than a year, and now that I did it, it wasn’t as dramatic as I imagined.

I have recently had a face and neck lift templelift with Booking Surgery. After doing a lot of research, I decided they were the right place for me to go. The inpatient team made me feel very comfortable and more relaxed about the whole process. The nurses service was outstanding! They worked like clockwork in terms of taking care of you and I particularly want to thank Benjamm, Leo, Mery and John. The translators, Martin and Sam, were wonderful and they addressed all my concerns and translated all my questions to the doctors and nurses. I had a coordinator, Chris Y Andrea, that was in touch with me from the first time I messaged Booking Surgery, and he is still in touch with me now, weeks after my surgery and returning home. I am very grateful for all his help, he has gone over and above his job to help me out. My hospital room was immaculate, cleaned daily and bedding changed. Food was appropriate for post surgery, and was all delivered following hygiene rules. I was run through all the discharge information with the doctors and felt happy knowing what my aftercare needed to look like once I returned home. I would definitely choose Booking Surgery again in the future and recommend them to anyone looking for top quality care. My surgery was with Dr Atacan Emre Koçman - he is exceptional at what he does and I am thrilled with my results.

I have shared my experience from my last intervention and I have to say they are a fantastic team, in terms of how they treat you, the care they provide, and their professionalism. I arrived with a lot of insecurities and I leave knowing that I have been in the best hands. Thank you once again.

I went to booking surgery last last week for a mummy makeover, i can’t express how amazing the care was! Reading everyone’s reviews there all spot on. From my first message with Pierre (who is great) my coordinator ☺️ answered all my questions promptly, all the staff are amazing I went on my own and when i was getting a little emotional they was all there to make me feel better! I could go on and on..I’m so glad for my first ever surgery I chose here to have it, and Dr Omer thankyou so much you have changed my life I feel amazing I’m forever grateful. I actually miss it there a little! Thankyou!

My coordinator was the brilliant Isabel walker who was in contact with me before and after surgery. I arrived with my brother on the 23/6/25 at Biruni hospital about 22.30 for a Gastric sleeve operation. Iam a 52 year old male 5 foot 11, 19 and half stone BMI 37.5. I suffer with shortness of breath acid reflux high blood pressure enlarged prostrate fatty liver severe obstructive sleep apnea and also recently been diagnosed with type 2 diabetes. When I arrived at the hospital within an hour the paperwork was done I had a ECG chest X-ray ultra scan blood test and blood pressure readings taken all within an hour of arriving 😯 The hospital is lovely like a four-star hotel and the staff are also very lovely smiley and helpful. I was shown to my room which was very modern and clean and nice. In your bathroom you have a lovely big shower toilet and sink. In your room you have a lovely fully adjustable electric bed with a TV on the at the end of the bed with the internet. You have a sofa and a sofa bed and a chair sink and fridge. I did the liver shrink diet 10 days before my surgery and also was walking up hills for 20 minutes a day and exercising before my surgery and drink 3 to 4 liters of water a day. In the first six days of doing the liver shrink diet exercising walking up hills and drinking 3 to 4 liters of water a day I lost over a stone 14 pound 11 in 6 days. 😯 The morning of the 24th of june I was taken to surgery at 07:30. after surgery I was in the recovery room then taken to my room shortly after that. my brother said I was gone for just under two hours. I had no pain after surgery and I believe it is because I stuck to the diet did lots of walking up hills exercising and drinking 3 to 4 liters of water a day. They encourage you to start walking straight away after surgery to get rid of gas and trap wind but I had none and I was walking straight away pain free. You will see other patients on the ward walking about trying to get rid of trap wind or gas. I speak to other people on the ward and they could not believe I just had surgery and was walking about completely normal but that is the honest truth I was walking about pain-free. I was there for four days and three nights and I was averaged about 9,000 steps a day walking about pain-free in the hospital and up the road to the local cafe with my brother. You cannot have a shower till a few hours before you go home. I bought one pack of Fresh Wipes Antibacterial Body Wipes For Adults which are nice and big and one pack is enough. I bought one TePe Hydrating Mouth Gel for Dry Mouth, mild Peppermint, Mouth Gel to Ease The Feeling of Dry Mouth. I also bought lip balm and infacol. you do not need to buy a bottle to spray water into your mouth because they supply a bottle for you and you can keep everything in your fridge nice and cool. Since I got home on the liver shrink diet and walking about and having the operation in 14 days I have lost just over 2 stone already and feel fantastic I have no side effects or no pain. If you ask me what is the number one advice I could give you is stick to the diet do loads of walking up hills exercise drink 3 to 4 liters of water a day before the operation to shrink your liver because it makes surgery so much easier for the surgeon less complications less surgery time and hopefully pain-free recovery like me. Go get the surgery done you will not regret it will be the best decision you could ever make and you will wish you did it years ago. Good luck and go and change your life for the better. 👍

I recently had a mini bypass surgery here and couldn't be more pleased with the experience. From the very beginning, communication was great, everything was clearly explained and I always felt informed and reassured. The nurses were truly amazing kind, attentive, and always ready to help with a smile. My surgeon was incredibly professional, calm, and made me feel completely confident in the procedure. On top of all that, the facility offers a lovely view of the sea, which made recovery feel a little more peaceful. Thank you to the entire team for such wonderful care!

From the very first text with my coordinator Deniz, I've felt in good hands. As soon as I stepped foot in biruni I was made to feel safe and the care is second to none. My surgeon for my gastric sleeve was Dr Kagan Katar and he was amazing. The staff are all so friendly and can't do enough for you. I would highly recommend if you're thinking about booking then do it. I've had an amazing experience.

I used booking surgery in July 2022 for a Gastric Sleeve with Dr Ali Tardu and managed to lose 9 stone. The care I received was excellent and I then decided to return in March 2025 for plastic surgery to remove the excess skin from my weight loss I booked through my coordinator Isabel who arranged my surgery with Dr Emin Atli for a 360FDL, Mons Lift, Muscle Repair and Arm lift. On arriving at Istanbul I was met by the transfer team and taken to Optimed International Hospital. The hospital was very clean and the nurses were very attentive, helpful and caring. The translators Jake, Chris and Olive couldn’t do enough for you they were so helpful and helped order in dinner/food etc they set up the Netflix in my room and made sure I had everything I needed. Dr Emin was very lovely and spoke good English with help of the translators I was made to feel informed and at ease during the whole process. The pre op tests were thorough and I was given the findings in a report in English to take home along with a copy of my blood results. The op itself was very successful and I’m overjoyed so far at my results. Dr Emin was in each morning following surgery to check on me and my recovery. I would 100% recommend anyone looking to book plastic surgery to use Dr Emin at booking surgery as I cannot fault the service I have received it has been exceptional from start to finish!
