Electrogastrographic study of patients with unexplained nausea, bloating, and vomiting

The role of electrogastrography and gastrointestinal hormones in chemotherapy-related dyspeptic symptoms

“…Symptoms reported by noncancer patients with functional dyspepsia may include unexplained nausea and vomiting. 12 However, according to data in the literature, patients with nausea and vomiting induced by chemotherapy have been reported to show no alteration in the gastric pacemaker. Besides, tachygastria seems to be secondary to vomiting rather than a cause of it.…”

“…Dysrhythmia seems to be correlated with antral hypomotility and delayed gastric emptying, as well as with symptoms such as nausea and vomiting. [12][13][14][15] Notwithstanding these findings, the direct effect of chemotherapy on the gastric pacemaker is not clear yet. 16 In contrast to motion sickness, chemotherapyinduced nausea may not be related to an increase in dysrhythmic gastric myoelectrical activity; 17,18 however, higher levels of gastric tachyarrhythmia before treatment may be related to post-treatment reports of nausea.…”

Gastric electrical activity in normal neonates during the first year of life: effect of feeding with breast milk and formula

“…Myoelectrical abnormalities of the stomach have been recorded in patients with unexplained nausea and vomiting, during pregnancy or motion, and in patients with anorexia nervosa, and dysrhythmia seems to correlate with antral hypomotility and delayed gastric emptying. [9][10][11][12] Neonatal motility studies (in both preterm and term infants) have demonstrated impaired gastrointestinal motility, characterized by the presence of motor quiescence alternating with episodes of nonmigrating phasic activity without clear migrating Background. To evaluate the effect of feeding with milk on the gastrointestinal tract, we studied gastric electrical activity in 27 healthy fullterm newborns (15 formula-fed newborns and 12 breast-fed newborns) during the first 6 months of life.…”

Retrograde Gastric Pacing Reduces Food Intake and Delays Gastric Emptying in Humans: A Potential Therapy for Obesity?

“…Numerous studies have shown that disturbances in the gastric slow wave are associated with impaired gastric motility (8)(9)(10)(11)(12). Tachygastria (abnormal gastric slow waves with a frequency of higher than 4 cycles/min) has been consistently shown to cause hypomotility of the stomach (12)(13)(14).…”
