I've read that if you have the sleeve, they cut the part of the stomach out that produces ghrelin. What about the bypass (which I'm having October 22nd. I know they don't cut part of our stomach out but by detaching it, does it decrease the ghrelin?

The "blind" stomach still produces the hormone. It is honestly the strangest sensation to not be hungry at all!

Well Dang, that's not the answer I wanted! lol!

From what my MD's office told me I wouldn't produce ghrelin anymore, and I had the bypass last week. Hope this helps

From different research sites it shows bypass reduces the hormone, as well as surgeries like vsg. Some research shows that hormone levels return to normal after a few years.

It is also produced in our small intestines, so unless we have all our stomach and intestines removed, we will still have ghrelin in some quantity.
