It was the right choice
What worried me most was the uncertainty and what the treatment plan would be. But my fears were put to rest after the very first consultation. The doctor was very attentive and explained everything in detail and calmly, which immediately put me at ease. I really appreciate that approach. All the staff at the clinic were responsive and supportive at every stage. The clinic itself made a good impression; everything is well organised. I am currently in the recovery phase and feel much calmer, having a clear understanding of the next steps. It was the right choice.
Everything was great

Thank you so much to the whole team for their clear, professional and heartfelt work!
I would like to express my sincere gratitude to Hisar Hospital Intercontinental in Istanbul for the high professionalism, attentiveness and care shown at every stage of my treatment. I underwent hysteroscopic removal of several endometrial polyps, including one large one measuring 3 cm. Everything went perfectly - from the initial consultation to the surgery and post-operative care. Special thanks to my doctor - Op. Dr Berna Buse Kobal. She inspired confidence from the very beginning, explained everything calmly and clearly, acted very carefully and confidently. After the operation I felt great, without pain or discomfort. The nurses and all the staff of the clinic were very attentive and helpful. The atmosphere in the hospital is clean, modern, comfortable and absolutely safe. I would also like to thank Julia, a Bookimed employee, who helped me with counselling and organising the trip. We made the decision literally at the last moment: we were informed from Dushanbe in the evening, flew out at night, and already in the morning I was in the clinic. Everything was organised perfectly - meeting, hospitalisation, surgery on the same day, and in the evening I was already relaxing in the hotel and feeling great. Thank you so much to the whole team for their clear, professional and heartfelt work! 💐 I confidently recommend Hisar Hospital Intercontinental and Bookimed to all women who are looking for quality, fast and safe treatment abroad.
Promptness, value for money. Approach.
There's no such thing

the support from the surgeon and the whole team was incredible
My biggest fear before the operation was adjusting to my new life, especially when it came to eating. But the support from the surgeon and the whole team was incredible. The operation was performed laparoscopically, and a significant portion of my stomach was removed—around 75–80%. Of course, recovery is a process. At the moment, I can only eat 2–3 spoonfuls at a time, and the main difficulty is that food can get stuck, so I have to get used to eating differently. Despite this, my energy levels have already improved slightly. I’ve realised the most important thing: forget your old eating habits! This is a new life in a new body, where you become a culinary connoisseur rather than a mere consumer of food.
