It should not be confused with hunger, the unpleasant, sometimes painful sensation caused by the body's need for food. Many stomach disorders and other illnesses result in or are accompanied by a loss of appetite, which is known medically as anorexia. Some physical dysfunctions, such as an overactivity of the thyroid gland, increase the body's energy requirements and stimulate the appetite. Such psychological conditions as depression may cause either compulsive eating or near loss of appetite.
Appetite suppressants are only a short-term solution for the treatment of obesity.
They should be used very rarely and in conjunction with a sensible dietary regimen.
