There are a variety that appear related to hunger, and yes they change after surgery. One is Grehlein SP? In any case its being studied. Once your MO nearly NO ONE EVER loses a 100 pounds or more and keeps it off 5 years. My surgeon says a norema sized persons stomach is the size of their fist. A MO the size of your head. its never full, and causes continious hunger:( This does decrease dramatically after WLS

The lower portion of the 'normal' stomach secretes a hormone called grhelin, whihc is responsible for most of our sensations of hunger. In the RNY, this part of the stomach is closed off into a 'blind pouch'---it no longer contacts food, but it continues to produce hormones. In the DS, this portion of the stomach is COMPLETELY REMOVED from the body, eliminating its' hormones as well. Yhis generally results in a huge, PERMANENT reducetion int he patient's sensation of hunger.

The RNY is well known for changing hormones, and the falling levels are highly related to decreased hunger.
