I was told today at my appointment that the VSG removes the Ghrelin production in your stomach. Then she followed that up with that it only lasts for about a year and a half, because your body and brain figure out how to make it again without that part of your stomach. What's the truth in this? What have you guys heard or personally experienced?

I had never heard that. I thought once it was gone, it was gone forever! Interesting!

my doctor told me your stomach can stretch a litle but the hunger never comes back

This is a 5 yr study that showed the levels stayed low the full 5 yrs.

My doctor said that I probably would never feel hungar again. But I would learn to recognize the sense of an empty tummy. I've never heard that it could return.
