My journey felt "perfect"
What stood out most was the surgeon's personal approach. He showed me exactly what would be removed and set very realistic expectations for weight loss, which built a lot of trust. He even visited me personally after my sleeve gastrectomy. My journey felt "perfect". The care was solid. The main challenge was communication, as the "language could improve" among some team members. From a practical standpoint, the final bill had no surprises or additional expenses. I stayed in the hospital for more than six nights, and the clinic has remained easy to reach since I left, which is a great support during this recovery phase.
