Report: 'Hunger hormone' could help chemo patients

NEW YORK - A synthetic version of the "hunger hormone" ghrelin might help limit the loss of appetite that can come with cancer chemotherapy, a small study from Japan suggests.
Ghrelin is a hormone secreted by the gut to boost appetite. Because of that, scientists have been studying it as a target in the obesity war, which has included work on an anti-obesity "vaccine" that inhibits ghrelin. The research, however, has met with little success so far.
