Sleeve vs RNY

They definitely do not physically remove the rest of the stomach in RNY. It remains inside and is reconnected to the bypassed intestine. One of the reasons I was initially considering VSG was the possibility of reduced production of the hormone ghrelin due to the complete removal of the excess stomach where the hormone is produced - which is not one of the benefits of RNY.

no, ghrelin is reduced in RNY more than VSG. despite the fact that the stomach remains in the body.

"In addition, bypass patients lost more belly fat and had improved insulin secretion compared with patients who had sleeve gastrectomy, even though their total weight loss was the same, according to Sangeeta R. Kashyap, MD, of the Cleveland Clinic, and colleagues.

The finding that bypass surgery patients had greater suppression of acylated ghrelin two years after surgery and had better metabolic outcomes, including pancreatic beta-cell function, suggests that ghrelin suppression may play a key role in improved glucose control, they wrote in the International Journal of Obesity, published online Nov. 22.

A two-year analysis of the trial, reported last June, showed that while both surgical techniques resulted in similar weight loss at 2 years, bypass patients had greater losses in android fat -- popularly known as belly fat -- and better rates of diabetes remission.

And even though the two surgical groups lost similar amounts of weight, Kashyap said the RYGB group lost about 10% to 15% more belly fat."

instead of everyone throwing out baseless claims, let's do some research and link to some studies, shall we?

Thanks for the correction! That's awesome news. I read the information about ghrelin in one of the books I read about WLS, but I did not research further after reading that claim. It's likely the book was written prior to the publication of that research, or it's possible it was simply written by a poorly-informed author lol. (I've noticed some of the commercial material about WLS seems hastily put together.) Regardless, I'm really psyched that I was wrong!
