need new doc

Hello, Congrats to everone who is getting sugeries done. I live between Tulsa and Stillwater,I had my RNY surgery a little over four years ago. I went to the Bariatric hospital in Wylie Texas.I went from 268 to 144 in less then 2 years,but have bounced back to 170 in the last year. Mine own fault. I just need to get back on track. Now for my question, I need to go in for a complete check up of my plumbing. I do get my blood work done twice a year. I would like to get everthing check out, I belive I might have a small ulcer. My doc was never very keen about me doing this surgery. My insurance is great so doc in or out of network is not a problem. Thanks
