What causes lack of appetite. A lack of appetite can be due to a variety of reasons. One reason for losing your appetite could be the side effects of a medication that you are on. It could also be the result of emotional causes such as stress, anxiety, or depression.
People with poor appetite or appetite loss may eat less than usual, not feel hungry at all, or feel full after eating only a small amount. Ongoing appetite loss may lead to weight loss, not getting the nutrients from food that the body needs, and loss of muscle mass and strength, all of which are serious complications. The combination of weight loss and muscle mass loss is called cachexia, or wasting.
