Sleeve Gastrectomy

Our entire family underwent surgery with Dr. Cuma, and we recommend him without hesitation. For us, he is the only specialist we would trust with procedures like this. Everyone is happy with the results, the care was attentive, and the approach was truly professional.

Gastric Balloon Removal

I have scoliosis, and excess weight started to seriously affect my health. On recommendation, I consulted the doctor. I previously had a gastric balloon, which the doctor carefully removed and then performed stomach reduction surgery. Everything went much easier than with the balloon — minimal pain and no issues with the stitches. I’ve already started losing weight and returned to my normal life. The doctor is very attentive, explains everything clearly, and the team is excellent as well.

Gastric Balloon

I underwent a gastric balloon procedure with Dr. Cuma, and today the balloon was removed. The results exceeded our expectations — I lost more weight than planned. Throughout the entire process, the doctor and the team stayed in touch, offering support and guidance. Everything went smoothly and without any problems.

Sleeve Gastrectomy

Before the surgery, I received detailed information, and the operation itself was performed well. I’m satisfied with the doctor — he explains everything clearly. The only point is that after surgery, I would have appreciated more follow-up support, as the doctor has a very busy schedule. Overall, I’m satisfied with the result.

Sleeve Gastrectomy

My quality of life has improved significantly after the surgery. I used to have difficulty breathing and problems with my legs. Now I’m down 32 kg — breathing, walking, and overall well-being have improved noticeably. The process is going well. My daughter also underwent a gastric botox procedure. I’ve already recommended the doctor to several people.
