Functional dyspepsia

Signs and symptoms resemble those of an ulcer, such as pain or discomfort in your upper abdomen, often accompanied by bloating, belching and nausea.

Sensation of bloating

Bloating is when your belly feels swollen after eating. It is usually caused by excess gas production or disturbances in the movement of the muscles of the digestive system.

Early satiety

Early satiety occurs when you are unable to eat a full meal, or you feel very full after eating only a small amount of food. Early satiety is usually caused by gastroparesis, a condition in which your stomach is slow to empty.

Anorexia

Is an eating disorder characterized by an abnormally low body weight, an intense fear of gaining weight and a distorted perception of weight.

Gastroparesis

Gastroparesis is a long-term (chronic) condition where the stomach cannot empty in the normal way. Food passes through the stomach slower than usual. It’s thought to be the result of a problem with the nerves and muscles that control how the stomach empties.
