OBESITY GASTRIC BAND. OBESITY GASTRIC BAND A gastric ring is indicated for the surgical treatment of morbid obesity. The principle involves squeezing a band around the upper part of the stomach in a way that it is divided in two, like an hour-glass. The small pouch of the stomach above the ring is quickly filled by ingested food and quickly leads to a full feeling. The food slowly passes through the constriction, into the remainder of the stomach, before being normally digested.
