Martina Tummy Tuck Forum; Tummy Tuck Message Board, Abdominoplasty Forum Hello I am planning to have done the gastric bypass soon. Does the surgeon have to know all my medicines please let me know thanks. Martina, Yes. Your surgeon and the anesthesiologist need to know all of the medications that you are taking. It is extremely important to tell them everything. The more they know about you, the safer your operation will be. Good luck. Tanner
