appetite

 [ap´ĕ-tīt]
the desire for food, 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. The stomach wall also receives an extra blood supply in preparation for its digestive activity. Appetite is psychological, dependent on memory and associations, as compared with hunger, which is physiologically aroused by the body's need for food. Lack or loss of appetite, known as anorexia, may be due to subjectively unpleasant food, surroundings, or company, or a symptom of either a physical disorder or an emotional disturbance. Excessive appetite may be an indication of either a metabolic disorder or an emotional disturbance.

appetite

Desire, whether for food, drink, sex, work or anything else that humans can enjoy. Lack of appetite for food is called anorexia, of which a particularly dangerous kind is ANOREXIA NERVOSA.

Appetite

The natural instinctive desire for food. It should be distinguished from hunger, which is the body's craving or need for food (either calories or specific nutrients).

appetite

the drive to eat. Influenced by the status of energy balance, psychological and behavioural factors and by health status. It may be increased or decreased pharmacologically. The drive to eat can be evaluated by using visual analogue scales (VAS) for self-report ratings of hunger, desire to eat, prospective food consumption (how much food one could eat), satiety and fullness. See also anorexia, bulimia, hypothalamus.

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.
