Great experience

I had a great experience! There was an element of hesitation and not being sure, as I found the clinic online and flew out the day before my gastric sleeve. But once I was there i felt much more relaxed, because everything was as described. From the pick up from the airport to the hospital staff being very attentive. Luckily my procedure went without any complications, and dr. Sisik along with his team was very good at explaining everything. The nutritionist dr was also very helpful, giving detailed guidance and recommendations for each of the stages following the surgery. Overall, a great experience. The only thing is that, other than the doctors, most of the hospital staff don't speak English, but that didn't bother me much personally since I was able to communicate with them with Google translate when necessary.

Gastric sleeve

Dr. Abdullah performed my gastric sleeve surgery with great expertise. From the very first consultation, he took the time to explain everything clearly and put me at ease. Throughout the entire process – from preparation to aftercare – I felt heard, understood, and safe. His warm, caring, and professional approach made a real difference for me.”

Great service the clinic and staff are incredible

I flew from london to do a gastric sleeve with dr abdullah at the end of may i was abit skeptical about doing a gastric sleeve but 2 of my family members have already done it with Dr abdullah and how he is the best for gastric sleeve in Istanbul. 6 weeks in after my procedure I am now 15 kg down the diet team give you a structured diet plan to follow. The after care service is really good and the clinic was really clean and the nurses made me feel safe. Luna who organised my visit was also very professional and polite.

I’d give 100 stars if I could.

I’d give 100 stars if I could.

The team took me in from the first contact. Explained everything perfectly, leaving me with a clear understanding of the whole process.
Always available to talk and answer my questions, they welcomed me at the airport and everything was really smooth from there.

I have reached a very impressive result. Better than I expected to be honest, thanks to Dr. Abdullah and the whole team.
I was able to eliminate 105kg since the surgery.

I literally have no words to describe how they changed and improved my life. I was at the bottom, feeling extremely exhausted and tired of living.
Now I’m happy and healthy, they literally gave me back my life.
Me, my family and my friends are eternally grateful for that.

I want my story to be an incentive to people who seek and need help to change.

Perfect service and the whole team is really really nice.

Everything was great👏🙌🙏🏻

Everything was great. The guidance, the care, the cleaning, the helpfulness of all the sisters and of course Dr. Abdullah himself. He stood next to my bed every morning at 8 o'clock to ask how I was doing and if I had any questions myself. A great team where I felt more than welcome. In the meantime, after 7 weeks, I have lost 13 kilos and I am already completely happy. Xxxx by Chantal

They have attended to my every need

They have attended to my every need, including the diet plan class which was amazing. Doctors and nurses made sure I took regular blood tests post-operation, and the doctor visited me daily just to check up on me.
I have to thank Ms Luna Dorothy for her patience and kindness throughout the whole Application process.

I had my surgery on the 21st of June and want to express my sincere gratitude to letsmedi, Luna, Dr. Abdullah Sisik and the entire team at Dr. He Obesity Clinic for making this overwhelming journey easy for me. The transparency, support and expertise of the entire team is what attracted me and even months after my surgery the team has been more than helpful and supportive.
All the best doc and the team

Dr. Abdullah, Luna & All Team of Letsmedi and Dr. HE are the most professional and caring group!

My overall health, specially liver was not doing well because of my obesity! On the other hand I had a fear of Gastric Sleeve because of hearing some horror stories 😂;
But, luckily I scheduled my surgery with Dr. Abdullah sir (The best decision of surgeon slection).
I was very worried before the surgery, they really helped me in all the ways possible! They treated me like a small 6 montjs old child!
The after-care was excellent! The hospital room, hotel, all medical facilities, drinks and foods and everything were very perfect and excellent!
The surgery procedure also completed cery well without even a small complication!
The follow-up of Dr. Abdullah and all his team after the surgery was outstanding!

I highly recommend Dr. Abdullah!
Thank you very much sir for your everything, and see you soon for my plastics.
Best Regards,
Rohullah

I made the absolute best choice in choosing Dr. Abdullah Şişik for my Gastric balloon and would return to him for any and all future cosmetic surgery. I spent a lot of time doing research and ultimately chose Dr Abdullah because I liked how thorough and thoughtful he was in our initial conversations. He took the time to ease my worries and was very direct about the process and I felt confident I would be in good hands. His team is very communicative and equally as invested in the patient as Dr Abdullah himself. Highly recommend!!! Thank you so much--- I am forever grateful!

Dr Abdullah Sisik and team…

I would like to start my review with the person or should I say the "star of the show", ⭐️ the coordinator LUNA!!!! She was extremely professional, patient with all of my questions and I was convinced to have my surgery in Dr. HE clinic. 🥰😄
The second step was to speak to the doctor via video chat and I must say after speaking with dr. Abdullah Sisik, I had no doubt in my mind that this is where I would like to get my surgery done. Dr Abdullah Sisik explained every aspect of the surgery, explained pros and cons and every detail that one should know before a procedure. After arriving in Turkey, the driver picked us up from the airport from the designated pick up point right on time, he was very pleasant too and took us to the hotel, which by the way was also very nice. 🏨

I met Dr. abdullah the next day who was just as pleasant in person as he was on the video chat. ☺️He once again showed up with his team and explained everything and asked me if I had any questions and answered my questions thoroughly and with patience. I got to meet the entire team (Im sorry I don't know the name of all the doctors and other staff), but from A to Z the entire team was professional, efficient, communicated everything with me in detail. Christophe and Zeynep (our nutritionists/dietitians, were amazing and thorough when they provided information to me. A special round of applause to Chriatophe for being super pleasant every time we saw him even in the hall and special thanks also for demonstrating the protein shake making process for us ☺️😊 👌

The facility was clean and the staff was very friendly.

I spoke to 6 different people in 6 different hospitals prior to speaking with Luna, but there was always a doubt in my mind until I spoke to Luna and later with Dr. Abdullah Sisik and got my procedure done. I give the entire team 10/10. Bravo guys!!! keep up the good work 👏👏
