I don't remember reading anything like this so my question is- why does my belly swell after eating? I was given Radioactive Iodine in 2002 and still believe that it was the wrong decision. I have since gained over 30 pounds which I cannot lose regardless of diet or exercise. I go for yearly blood tests and my Dr claims everything is fine. My last meal was five hours ago ( a turkey and cheese sandwich) I now look to be six months pregnant and I am still full. I went thru a phase where I never felt full regardless of how much I ate. I hope that someone has advise for me. Thyroid problems suck. I asked my Doctor about my belly and he had the nerve to tell me to wear a foundation garment. Hope you can help.
