The association between symptoms (Sx) and gastric function tests remains unclear. Aims: To determine whether specific clinical complaints and a history of GERD were associated with gastric emptying (GET) or EGG findings. Charts of 163 pts (39 M, 124 F) undergoing both GET and EGG were reviewed for weight, diabetes and complaints of nausea, pain, vomiting, bloating and altered bowel habits. The 1 and 2 hr GET, final EGG diagnosis and baseline frequency distribution of power, and volume (vol.) tolerated during the water load test (WLT) were noted. Data is reported as median, 5–95 percentile. Chi‐squared‐ and Wilcoxon‐Mann‐Whitney‐tests were used. Results: Women (F) complained of pain more than men (M) 70% vs. 43% (p = 0.002) and more men had altered bowel habits 77% vs. 57% (p = 0.02). No gender differences were seen with other Sx. F weighed less and drank less than M during the WLT (480 vs. 604 ml, p = 0.001). GET was slower in F than M: 63%, with 7–97 (median, 5–95 percentile) emptying in 2 hrs in F vs. 78%, 27–99, in M, p < 0.001. There was no gender difference in EGG diagnoses. Diabetics weighed more (187 vs. 146 lb, p < 0.0001) and were older (52 vs. 42, p < 0.01) than nondiabetics who had more a normal baseline EGG than diabetics. Overall, the Sx of pain was associated with a lower vol. tolerated on WLT, 450ml vs. 600 ml, p = 0.002. Only the Sx of pain was associated with delayed GET, which did not persist when adjusted for gender. No Sx complaint was associated with specific EGG diagnoses. GERD was associated with greater weight (156 lb vs. 140 lb, p < 0.05) but not with delayed GET or any specific EGG findings. Conclusions: GET was slower in F than in M. Pain was a more common presentation in F and the association of pain with a lower WLT vol. suggests that this Sx is related to an abnormal sensory process and suggests a different therapeutic approach to such pts.
