"This is my 2nd time coming back to Dr. Drewitz office after 10yrs. The guideline to medication is clearly, doctor office call, texting to reminds me to follow the instruction, see if I have any question, problem. Then came the procedure day, it went smoothly, the hospital was very clean, the nurses was very nice & helpful. I was very relaxed, sleep, they woke me up and it was done. The next day doctor office call to see if I have any issues, which I don't have. I think when we heard of the word colonoscopy, your mind started to wound up, worries, feeling uncomfortable, but if we just follow the guidelines. Know and understand it purposes, preventing 'C.C', I rather get it done than get hit with the surprise. Thank you Dr.Drewitz and the staffs for taking care of me 😊 Update: 8/8/23 doctor office called yesterday, the polyps was benign, doctor want me to return in 10 years. Yay. 🙌"
