Motility of the Human Digestive Tract under Resting Conditions and After Ingestion of Food

Abstract

The motility of the digestive tract in healthy persons was studied by means of pressure-sensitive endoradiosondes, under resting conditions during the night and after ingestion of food. In the stomach, slow pressure waves were observed with a frequency of 3-5 conbactions per min and pressures of up to 10 em HsO, as well as activity in the form of relatively rapid pressure increases of up to about 25 cm H,O---so-called type I1 waves. These waves were observed especially in the antrnm. After ingestion of food increased activity was recorded in the form of a higher frequency of type I1 waves. In the small intestine waves of botb type I and type II were recorded. Immediately following ingestion of food the intensity of both type I and type I1 waves increased. In the colon, waves of types I, 111 and IV were recorded. After ingestion of food the intensity of the type I11 and IV waves was increased.Activity during the night was considerably reduced in relation to that during the daytime. However, activity was recorded in all subjects; this was usually of type I, though bursts of type III waves were also recorded.

Dopa responsive irritable bowel syndrome: restless bowel syndrome or a gastrointestinal variant of restless legs syndrome?

“…The gastrointestinal motility depends on food and water intake. Ingestion of food increases gastrointestinal activity 20. The human eating pattern is usually restricted during the daytime and in the early part of the night.…”

Motor Activity of the Distal Ileum and Ileocecal Sphincter and Its Relation to the Region’s Function

“…Distal ileal motor activity certainly in creases following food -the so-called gastro ileal reflex [57][58][59], The precise nature of the postprandial response is unclear, however, some describing an increased incidence of irregular phasic contractions, typical of the fed response elsewhere in the small intestine [26,58], while others report development of more discrete patterns [60,61].…”
