Appetite

Mentioned in: Appetite-Enhancing Drugs
appetite
the desire for food. It is stimulated by the sight, smell or thought of food and accompanied by the flow of saliva in the mouth and gastric juice in the stomach. Appetite is psychological, dependent on memory and associations, as compared with hunger, which is physiologically aroused by the body's need for food. Its existence in animals can only be conjectured on the response in the form of food intake. Chronic loss of appetite is known as anorexia.
decreased appetite
see anorexia.
depraved appetite
see pica. Called also allotriophagia.
increased appetite
see hyperorexia, polyphagia.
salt appetite
the appetite for salt displayed by animals, especially ruminants, at pasture. Used in the manangement of cattle on extensive range. See also salting.
appetite stimulants
there are several methods available. Bitters such as gentian and pulv. nux. vomica exert some effect in ruminants, probably by stimulating alimentary tract mucosa. Anabolic steroids are sometimes used for this purpose in dogs and cats. A nutritional deficiency of zinc or the B vitamin complex depresses acuity of appetite and dietary supplementation with it can be effective as an appetite stimulant. Suppression of the medullary satiety center by barbiturates and benzodiazepines is also recommended. There are no well-regarded stimulants of the hunger center of the lateral hypothalamus.
