my recovery from reconstructive vaginoplasty has been much better than expected
If you're thinking about this procedure, I'd tell you that my recovery from reconstructive vaginoplasty has been much better than expected. The whole process felt very supported. It was so helpful that my surgeon took the time to explain the dilation schedule clearly, which made me feel confident about aftercare. The clinic staff have also stayed in touch since I left. Do be aware that you'll need to pay for medications you take with you from the hospital. A final tip: bring your own sanitary towels and be sure to budget extra money for travel, food, and sightseeing, as hotel stays generally only cover breakfast.
Great fast response from Bookimed very helpful information and hospital referral liliia was very helpful in giving me information and guidance

The surgeon, staff, and clinic all get a 5/5 from me
My biggest worry was the recovery itself, specifically how tired and weak I would feel. I have to say, my energy level has been better than expected for this early stage. It’s a relief. The surgeon, staff, and clinic all get a 5/5 from me. The biggest eating challenge right now is having no appetite at all, which is an adjustment when you know you need to get your liquids in. I can manage about a quarter cup per sitting, which makes sense given they removed 80-85% of my stomach. Overall, this was the right decision and I would certainly recommend this clinic.
Every Question Answered,
Always Kept Intouch,
So Helpful and Kind,
I couldnt be more comfortable with how Bookimed handle everything. They did an amazing job and any doubt or worry I had they made sure to not worry. The hospital I went to was amazing and they did everything thoroughly. The doctor assigned to me was amazing and so good. After the procedure I was allowed to go back to my hotel 2 days after. My translator Betul on the 2nd day to the day I left was amazing and so pleasant to speak to.
The English Translator on the first day was nice but very invasive and asked personal questions which he was asked not to ask and you could tell that he didnt have much experience.

To be honest, if a friend asked me, I wouldn’t recommend this treatment. It’s been 15 days, and so far the results have been rather modest — my blood sugar levels have improved slightly, but that’s about it. The clinic itself deserves high praise; everything is very modern and clean. However, the work of the doctor and staff left a mediocre impression. When I asked questions, time was limited, and I didn’t manage to ask everything I wanted to; the doctor simply said, ‘If you like, come back tomorrow.’ The consultation lasted a mere 15 minutes. The transfer services were very poorly organised, with issues regarding punctuality, constant waiting and frequent changes of interpreters. Perhaps there will be improvements to the treatment in the future. Overall, I got the impression that the hospital’s primary concern is simply making money, and everything else is of secondary importance.

I was very satisfied by Memorial hospital's men’s essential health check-up
I was very satisfied by Memorial hospitals men’s essential health check up. Everything went very smoothly, and I feel that my concerns were addressed, and the tests were explained well. I have my results. To show my doctor back home.
Getting important medical tests that I’ve never had my life at 67 like stress test EKG, ultrasounds of my abdomen, and neck
It really can’t be helped, but that the hospital is a little far out of the center of Istanbul
