I feel hungry frequently and am starting to get a little concerned. I had my surgery May 22, about 2 1/2 weeks ago. I have already started eating solid foods (i.e. chicken, salmon, burger, etc), which seems aggressive, but my surgeon said for me to start stage 3 on week 3. I get all my protein and water in daily, but am not sure if it's "head" hunger - where I am just missing food and my mind is messing with me, but it feels real. I've read and heard that acid in the stomach can mimic hunger. If you continue to get hungry ask your Dr. There are some people on a ppi that can help calm the acid, thus make you not misinterpret for hunger. Good luck
