It took my nurse two weeks to call me. Then she will give you a number to talk to call to set up dietitian calls. Honestly you can call optum even before the nurse calls you and get the ball rolling to enroll in the wellness program. You will get 6-8 calls within 6-7 months from the dietitian (basically 1 call a month 3-10mins), in my case thats how it is. When the nurse finally calls she will ask you questions, why this surgery have you heard of the other bariatric surgeries, what medication you take, why do you want to have this surgery and a family history. GOOD LUCK. Even though I am planning for a may/june surgery I will still be taking classes maymester, summe 1 and summer 2. It must be done though!
