Wish there was a 10 star option! Absolutely fantastic from start to finish. Me and my partner were blown away by the care and service we were given. The hospital was so modern and clean. It was constantly been cleaned. The nursing staff were all incredible and even helped my partner with various different things. I literally couldn’t recommend going with this company any more if I tried.

Dr hasan is the best Love love love! Im in love with my sleeve already 10 days out and Dr hasan also fixed a hernia he found during surgery at no extra cost. Bye bye heartburn! He personally came round every day to change my dressings and check on me.All staff and transport also excellent and the hospital is modern and immaculate. I love dr hasan ❤️❤️❤️

What can i say? I've had a amazing experience,everything was very profesional,transportation,hotel stay,not to mention this so nice and esquisit people who loked after me.My surgery went very well same as the recovery. Thank you very much indeed.

I had a gastric sleeve two weeks ago… I had a gastric sleeve two weeks ago with Prof Hasan at BHT clinic Instanbul. The care I received from him and his team was outstanding from start to finish! When I pressed the nurse call button there was someone with me in seconds. I always felt looked after and in safe hands. The clinic itself is far in front of us in the UK too. While recovering I watched YouTube and caught up on programs I'd missed from home on the TV right in front of my mobility bed. My husband came with me and he was so sold on the clinic he wants to go back for his teeth done. Even the restaurant downstairs was brilliant and so cheap!

Trip to my new body I had a gastric sleeve done, there were some small issues but really nothing major. It was a bit difficult to communicate as I don't speak Turkish and most people and doctors don't speak in English (or very little), but the comfort and organisation was good(just on arrival to Istanbul Airport I had to wait for my transfer nearly 3hours, that wasn't great as I was tired after flight and it was night time), but then I was taken to a great hotel and had a good night sleep), after all I am losing my weight, but it is just 6 weeks with my new stomach, so can't tell final result, but hope to be in my best shape very soon.

I can not thanks Prof Husan for giving… I can not thanks Prof Husan for giving me my life back. I put my life in his hands. I wasn't sure of to be re sleeved or have bypass. I left the decision to him. He is the expert after all. If I had to do it all again I wouldn't change a thing.

Excellent care I had a gastric sleeve performed by Dr Hasan Abuoglu and his team 3 weeks ago. The care and service I received was excellent, from being picked up at the airport and taken to the hospital, to the amazing nursing staff and the expertise of the surgeons. I was very well looked after and taken from the hospital to the airport. My procedure was successful with no complications.

I traveled form London to Turkey 10 days ago and had gastric surgery. Dr Hassan was my doctor and he was outstanding along with the other doctor involved with the surgery. The nurses where so caring and did not stop making sure that I was ok before and after my operation and all my needs met.The only downside was the lack of English but even that was not a big issue Thank you all so much at Obesity Clinic 😊😉🙏🏻

Amazing 1st class treatment I would really like to thank Dr Hassan and his fantastic team. I recently travelled to istanbul for a sleeve gastrectomy. I arranged everything through WhatsApp, and all questions i had were answered immediately by Dr Hassan's team... I would highly recommend the obesity clinic istanbul to anyone who is contemplating surgery. They have truly changed my life and I can not express my gratitude enough. Thank you to all of you.

The surgery went well, staffs were very supportive and attentive . I could not have asked for a better experience. I recommend Dr Hassan and his team for any obesity surgery. Many Thanks again 😊

Very happy with this hospital and surgeon. All the nurses were lovely, they had some English but I would recommend using Google translate too. The hospital is spotless, constantly had cleaners coming in to the room also lovely people. Dr Hasan was very nice and I trusted him completely to do my surgery. I'm healing really well and have had no complications. I would definitely recommend Dr. Hasan.

I loved this clinic, my operation and the treatment that everyone gave me since I arrived was excellent, the truth is that I felt very well, my recovery was very fast and I lost a lot of weight and now I am more beautiful, I recommend this hospital and the doctor

I am very pleased with my professor, Associate Professor Hasan Abuoğlu. He successfully performed sleeve gastrectomy for both my wife and my son. Frankly, he is a very good physician with surgical hand practice. He pleased us very much with his moral and motivational speeches. Do people who will really choose surgery for the treatment of obesity, a very successful physician. Dr. I recommend Assoc.Prof.Hasan Abuoglu to contact the doctor without hesitation by making an appointment. Regards.

Dr. Hasan performed the gastric sleeve surgery of my wife. She began to recover and lose weight soon. Prof.Hasan  and his team know this job very well and they do it professionally. Their attention before and after the operation is very good. Thanks to Prof.Hasan, his team and Kudret Bey for their efforts…

I had surgery on December 12, 2019 and my life has changed. I am at a time when I feel like I was born again I went into the surgery with 121 kilos, now I am 59 kilos. It’s been 10 months. I am indebted to Hasan, who performed the surgery.  Thank you very much for your hard work.

I met my proffessor Mr.Hasan two and a half months ago. When I decided to have the surgery, I had a lot of worries, but prof.Hasan helped me to decide in a very nice way by explaining how the surgery would be and what kind of process I would go through. Glad  I had the surgery. It is good that I got to know prof.Hasan. I am glad that I got to know my client; Kudret Gülcan. They are very good at their job. As a team, they answered all my questions tirelessly. I said hello to life for the second time. I can’t pay your dues. May Allah be pleased with my client Kudret Bey and of course prof.Hasan Abuoglu thousands of times from the whole team.

I have been researching gastric sleeve surgery for a long time. I’ve talked to a few doctors about this. I went to an interview with prof. Hasan, on the recommendation of those who had surgery. In the first meeting, he talked to us about all the details of the surgery for 45 minutes. He is a doctor with very strong communication and human analysis. He was also very interested after the operation. It gave morale and motivation at every check-up. He certainly doesn’t see it as done. He follows and knows and knows his patients. This was very important to me. I had surgery on January 26th, I lost 23 kilos in 3 months and I continue to lose weight… Thank you, my respected professor.

On July 11, 2020, Dr. Hasan performed diabetes surgery on me. After 5 months I don't have diabetes and all my tests values ​​are back to normal. I had surgery by an incredibly caring doctor. I can't thank him enough. If there are any of you who hesitate to have this surgery, you should definitely talk to Mr. Hasan. Everything he said before the surgery started to form one by one. I have no diabet left, diabet-related ailments started to disappear as he said. Thank you so much Mr.Hasan.

    Gastric Sleeve, which has an important place in the treatment of obesity, is a vital surgery for people who have difficulty in losing weight today. In this surgical operation, the main goal is to reduce the storage capacity of the stomach, and as a result of the operation, the stomach has a tube-shaped appearance. With the operation, a large part of the stomach is irreversibly removed and turned into a system that continues with the esophagus and intestines. As a result of this operation, which lasts about 1.5 hours, a great decrease in the appetite of the patients is observed.

    There are many methods used in bariatric surgery. Gastric Bypass surgery is one of the most preferred surgical methods in obesity surgery. Gastric Bypass surgery is the most common type of combined surgery. Gastric Bypass is one of the methods that draws attention with its successful results in bariatric surgery. It results in reliable weight loss with acceptable risks and minimal side effects. With this surgery, while the stomach volume is reduced, the absorption of nutrients decreases because the path traveled in the small intestine is shortened. In this way, patients reach the feeling of fullness quickly with much smaller portions. At the same time, the absorption of a significant part of the high-calorie foods taken is prevented.

    It is one of the most preferred risk-free obesity treatments today. Another name is gastric balloon. It is not a surgical procedure, but the procedure is performed under light sedation, with the endoscopic method, within 15-20 minutes.

    It is applied by inflating it after placing a balloon in the stomach. With this method, the feeling of fullness is provided in a shorter time due to the earlier filling of the stomach. However, it is a temporary method. The gastric balloon stays in the stomach for 6 to 12 months. After 6-12 months, the gastric balloon is removed from the patient’s stomach.

    In studies with a gastric balloon, a significant regression was found in metabolic syndrome, diabetes, gout, and cholesterol-triglyceride levels after 6 months-1 year follow-up.

    Diabetes is one of the most common diseases in the world due to changing lifestyle and diet. Opportunities in the treatment of diabetes, which arise independently of the pancreas’s capacity to produce insulin and are caused by environmental factors rather than genetic predisposition, are quite advanced. The treatment of the disease starts from the diagnosis and the first thing to do is lifestyle changes. These changes, such as removing sugar from the diet, starting sports exercises, and switching to a regular life, save many patients years. The treatment of diabetes has become much easier with the development of metabolic surgery today.

    The application of surgery in the treatment of diabetes is determined by the joint decision of the patient and the doctor. In Istanbul Surgery, Assoc. Dr. Hasan Abuoğlu and Assoc. Dr. Mehmet Kamil Yıldız evaluate the patient’s condition with the necessary tests and examinations and prepare a very comfortable and safe treatment environment in this regard.

    Revision surgery is an operation performed if the patient cannot lose weight or continues to gain weight after the previous bariatric surgery process. Two of the most famous names in bariatric surgery in Istanbul, Assoc. Dr. Hasan Abuoğlu and Assoc. Dr. Mehmet Kamil Yıldız, provide a reliable and comfortable service to patients in Istanbul Marmara Surgery in revision surgery.

    As a result of this operation, which lasts about 1.5 hours, a great decrease in the appetite of the patients is observed.
