On a return visit after receiving a diagnosis of functional dyspepsia, a 35- year-old woman reports sensations of early satiety and discomfort in the epigastric region after a meal. These symptoms are most likely a result of:
Malfunction of adaptive relaxation in the gastric reservoir Elevated frequency of contractions in the antral pump An incompetent lower esophageal sphincter Premature onset of the interdigestive phase of gastric motility
