Somatostatin , also known as growth hormone-inhibiting hormone GHIH or by several other names , is a peptide hormone that regulates the endocrine system and affects neurotransmission and cell proliferation via interaction with G protein-coupled somatostatin receptors and inhibition of the release of numerous secondary hormones. Somatostatin inhibits insulin and glucagon secretion. Somatostatin has two active forms produced by the alternative cleavage of a single preproprotein: one consisting of 14 amino acids shown in infobox to right , the other consisting of 28 amino acids. Synonyms of "somatostatin" include: [ citation needed ]. Somatostatin is secreted by delta cells at several locations in the digestive system, namely the pyloric antrum , the duodenum and the pancreatic islets. Somatostatin released in the pyloric antrum travels via the portal venous system to the heart, then enters the systemic circulation to reach the locations where it will exert its inhibitory effects. In addition, somatostatin release from delta cells can act in a paracrine manner.

Somatostatin is a hormone produced by many tissues in the body, principally in the nervous and digestive systems. It regulates a wide variety of physiological functions and inhibits the secretion of other hormones, the activity of the gastrointestinal tract and the rapid reproduction of normal and tumour cells. Somatostatin may also act as a neurotransmitter in the nervous system. The hypothalamus is a region of the brain that regulates secretion of hormones from the pituitary gland located below it. In addition, somatostatin is produced in the pancreas and inhibits the secretion of other pancreatic hormones such as insulin and glucagon. Somatostatin is also produced in the gastrointestinal tract where it acts locally to reduce gastric secretion, gastrointestinal motility and to inhibit the secretion of gastrointestinal hormones, including gastrin and secretin. Chemically altered equivalents of somatostatin are used as a medical therapy to control excess hormone secretion in patients with acromegaly and other endocrine conditions, and to treat some gastrointestinal diseases and a variety of tumours. In the same way that somatostatin controls the production of several hormones, these hormones feedback to control the production of somatostatin. This is increased by raised levels of these other hormones and reduced by low levels. Somatostatin is also secreted by the pancreas in response to many factors related to food intake, such as high blood levels of glucose and amino acids. Too much somatostatin results in extreme reduction in the secretion of many endocrine hormones. An example of this is suppression of insulin secretion from the pancreas leading to raised blood glucose levels diabetes. As somatostatin inhibits many functions of the gastrointestinal tract, its overproduction may also result in the formation of gallstones , intolerance to fat in the diet and diarrhoea.

In the exocrine system, somatostatin inhibits bile secretion, colonic fluid secretions, gastric acid secretion, pancreatic enzymes, cholecystokinin, and vasoactive intestinal peptide VIP. Unsourced material may be challenged and removed.

Growth hormone—releasing hormone GHRH , also known as somatocrinin or by several other names in its endogenous forms and as somatorelin INN in its pharmaceutical form , is a releasing hormone of growth hormone GH. It is a 44 [1] - amino acid peptide hormone produced in the arcuate nucleus of the hypothalamus. GHRH first appears in the human hypothalamus between 18 and 29 weeks of gestation, which corresponds to the start of production of growth hormone and other somatotropes in fetuses. GHRH is released from neurosecretory nerve terminals of these arcuate neurons, and is carried by the hypothalamo- hypophyseal portal system to the anterior pituitary gland , where it stimulates growth hormone GH secretion by stimulating the growth hormone-releasing hormone receptor. In addition, GHRH also promotes slow-wave sleep directly. The GHRHR is a member of the secretin family of G protein-coupled receptors , and is located on chromosome 7 in humans.

Somatostatin is a hormone peptide that plays a vital role in many bodily functions. The most notable are brain function and gastrointestinal processes. The hormone stops the release of other hormones, specifically human growth hormone HGH. By doing so, it essentially regulates bodily functions and processes by controlling how much other hormones are released at certain times. This article discusses the function and uses of somatostatin and the conditions associated with the hormone. The body produces somatostatin naturally. Various somatostatin receptors in the body work with somatostatin to prevent hormone release for the proper functioning of various bodily systems.

Within these systems, there is a wide array of hormones that are affected. The inhibitory effect of somatostatin leads to decreased gallbladder emptying as well as reduced cholecystokinin production, which results in gallstones.
