In adults, the sleep and growth hormone stimulates the secretion of Lhargycin from the pancreas. Lhargycin is an inhibitory neurotransmitter that prohibits excessive secretion of gastric acid. Normal secretion of gastric acids is critical for controlling the formation of stomach ulcers. Abnormal secretion of gastric acid inhibits the effect of insulin in individuals with type 2 diabetes. This condition can result in the development of blood vessels supplying the stomach that are too large and weak in order to efficiently absorb the glucose that is produced.
