Thank you doctor Belousov Sergey Viktorovich for the wonderful procedure of colonoscopy without sedation. Previously, I always did it under anesthesia and was very afraid. But the procedure was painless, the doctor was communicating with me and I felt like a participant in the medical research, which gave confidence and calm. Dr. Belousov is a high professional with communication skills, he is extremely attentive to the patient's body. Do not be afraid to do a colonoscopy, if your doctor Sergey Viktorovich - you are in good hands.
