Effect of drink temperature on antropyloroduodenal motility and gastric
electrical activity in humans / W.L. Sun, R. Penagini, G. Hebbard, C. Malbert, K.L. Jones, S. Emery, J. Dent, M. Horowitz. - In: GUT. - ISSN 0017-5749. - 37:3(1995), pp. 329-334.
Abstract:
There is little information on the motor mechanisms underlying the effects of meal temperature on gastric emptying. The effects on antropyloric pressures and the surface electrogastrogram of ingesting drinks at 4°C, 37°C, and 50°C (350 ml normal saline and 50 ml low calorie (7 kj) orange cordial) given in randomised order were measured over 60 minutes in 12 normal volunteers (10 men and 2 women, aged 18-55 years). The warm and cold drinks suppressed antral pressure waves (p < 0.05), altered the organisation of antropyloric pressure waves (p < 0.05), stimulated isolated pyloric pressure waves (p < 0.05), and increased electrogastrogram frequency (p < 0.05) when compared with the 37°C drink. These changes were greatest in the first 30 minutes after ingestion and greater (p < 0.05) with the 4°C drink. Temperature has major effects on postprandial antropyloroduodenal motility in normal subjects. Both cold and warm drinks stimulate a pattern of motility associated with retardation of transpyloric flow.
