Introduction: Gastroparesis (GP) and functional dyspepsia (FD) present with overlapping upper gastrointestinal (GI) symptoms, such as: nausea, vomiting, early satiety, postprandial fullness, epigastric pain, and bloating. Other gastrointestinal motility disorders may be concurrent in patients with GP. The goal of study was to compare the presence of GI symptoms and other motility disorders in patients with GP and FD.

Methods: A retrospective cohort study was performed on IBM Explorys (1999-2022), which contains de-identified healthcare information from more than 64 million patients across the United States. Adult patients who have completed gastric emptying study were selected, and subsequently divided into GP and FD cohorts. GP cohort consists of patients with a diagnosis of gastroparesis, with exclusion criteria: cyclical vomiting syndrome, psychoactive substance abuse, eating disorder, factitious disorder, malignant tumor of esophagus and stomach, neoplasm of abdomen, gastric or intestinal obstruction, IBD, adhesion of intestine, carcinomatosis, perforation of intestine, Roux-en-Y gastrojejunostomy, and gastrectomy. FD cohort was similarly constructed with additional exclusion criteria: gastroparesis, gastrointestinal ulcer, brain neoplasm and pancreatitis. The presence of GERD, IBS, GI symptoms and common GI medications were collected. Odds ratios (ORs) with 95% confidence interval were used to compare the cohorts.

Results: GP and FD cohort consisted of 17,570 and 60,230 patients respectively (Table 1). There was a higher prevalence of concurrent motility disorders in patients with GP than FD, including GERD and IBS (65.1 vs 50.9%, 18.6 vs 13.3%). Patients with GP tend to present with more upper and lower GI symptoms than FD, including nausea (65.1 vs 46.3%), vomiting (53.0 vs 33.3%), epigastric pain (36.9 vs 27.2%), heartburn (8.6 vs 7.5%), diarrhea (34.6 vs 23.3%) and constipation (37.2 vs 21.8%) (P< 0.0001) (Figure1). However, there was no difference in terms of early satiety and bloating when comparing the two groups. Acid reducing medications, anti-nausea medications and prokinetic agents were more commonly prescribed for patients with GP than FD, including proton pump inhibitors (PPIs), H2 receptor antagonists (H2RA), Metoclopramides and Ondansetron (p< 0.0001).

Discussion: GP is associated with more concurrent GI symptoms and motility disorders compared with FD. Acid reducing medications, anti-nausea and prokinetic medications are more commonly prescribed for patients with GP.
