Had the sleeve done a year ago and have started to gain weight back. My doctor tried to give me diet pills but they made my heart race. Now I have asked them about having the DU and was told that there may be a waiting period. can someone please tell me what the waiting period is and why wasn't I offered the DU first by my doctor?

What's the DU? Are you talking about a duodenal switch?

Any waiting period is probably determined by your insurance. I had to do a six month diet program before my sleeve (which was the best thing for me for absolute sure...).

Why are you gaining weight? What does a typical day's consumption look like for you? If you don't change your relationship with food, you'll gain weight after any surgery. Any of the available procedures are just a tool. It's the hard work that you make committing to change and making the right decisions every day that make you successful long term.
