Functional Dyspepsia and Gastroparesis
Functional Dyspepsia and Gastroparesis
Functional dyspepsia (FD) and gastroparesis (GP) are the two most common sensorimotor disorders of the upper gastrointestinal tract. The prevalence of FD is estimated at 10%, and that of GP is approximately 1.5–3%. In an attempt to simplify the evaluation, diagnosis, and treatment of patients with symptoms of upper abdominal pain, postprandial fullness, early satiety, and nausea, researchers and clinicians classify these disorders into separate and distinct categories. However, this classification system confuses both patients and clinicians, as symptoms are similar and treatment is frequently the same. This review is designed to highlight the similarities of these two prevalent gastric neuromuscular disorders and initiate a debate on restructuring the current classification system in an effort to clarify the diagnosis and treatment of patients with FD and GP.
