Functional Dyspepsia is a common digestive disorder characterized by persistent or recurrent pain and discomfort in the upper abdomen. It is not caused by any identifiable physical abnormalities or diseases, making it a "functional" condition. Symptoms may include bloating, nausea, and early satiety, which can significantly impact daily life. The exact cause of Functional Dyspepsia is not well understood, but it may involve factors such as abnormal gut motility, increased sensitivity to stomach distension, or psychological stress. Diagnosis typically involves ruling out other gastrointestinal disorders, and treatment may include lifestyle changes, dietary adjustments, and medications to alleviate symptoms.
