Abstract

Background: The correlation between symptoms and observed impaired function in functional dyspepsia is still inconsistent. The aims of the study were to obtain a measure of satiety by a meal test; to verify whether this compares with severity of symptoms assessed using a reproducible questionnaire; and to correlate the parameters of satiety test and gastric emptying with all the dyspeptic symptoms. Methods: Fifty-two functional dyspepsia patients reported their symptoms on a standardized questionnaire that considered belching, bloating, early satiety, epigastric pain and burning, nausea, postprandial fullness and vomiting. They were monitored for gastric emptying of a solid caloric meal using a radionuclide technique and underwent a test to quantify meal-induced satiety by a liquid caloric meal. Results: The number of kilocalories ingested during the satiety test until the occurrence of maximum satiety in healthy subjects was 110% higher than in the dyspeptic group (mean ± s: 1110 ± 23 versus 532 ± 56; P <0.01). We found a significant positive correlation between gastric emptying rate and kcal of the satiety test (P <0.01; r = 0.428). Logistic regression showed a significant inverse association between severity of early satiety-coded as absent, mild, moderate or severe, kcal of meal test (P = 0.01), and gastric emptying lag phase (P=0.03). Bloating was associated directly with t1/2 of gastric emptying (P = 0.03) and inversely with lag phase (P = 0.02). Conclusions: The satiety test gives a fine numerical measure of satiety and confirms the results of a symptoms qnestionnaire. Our study showed an indirect correlation between severity of early satiety - as measured by the satiety test, and gastric emptying rate, as well as an association between bloating and delayed gastric emptying.
