Each subject took a standard diet for four days and stool output was monitored throughout this period. Administration of lactulose on day three significantly increased stool weight and frequency in patients with both active and quiescent total colitis (p less than 0.01), but not in patients with distal colitis or in the volunteers. The basal and peak breath hydrogen responses to ingested lactulose were similar to normal controls in all patient groups but the hydrogen concentration tended to be higher in colitics. The mouth to caecum transit of the lactulose meal was slower in all groups of colitics (p less than 0.02) when compared with controls. These results suggest that impaired colonic salvage of carbohydrate could contribute to the diarrhoea in patients with total colitis who are ingesting a diet rich in unabsorbed carbohydrate, or who are hypolactasic.<\/jats:p>","DOI":"10.1136\/gut.28.9.1090","type":"journal-article","created":{"date-parts":[[2007,9,18]],"date-time":"2007-09-18T17:41:31Z","timestamp":1190137291000},"page":"1090-1094","source":"Crossref","is-referenced-by-count":15,"title":["Is the diarrhoea in ulcerative colitis related to impaired colonic salvage of carbohydrate?"],"prefix":"10.1136","volume":"28","author":[{"given":"S S","family":"Rao","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"N W","family":"Read","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C D","family":"Holdsworth","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[1987,9,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"880","DOI":"10.1136\/gut.13.11.880","article-title":"The absorption and secretion of water and electrolytes across the healthy and the diseased human colonic mucosa measured in vitro","volume":"13","author":"Archampong, E.Q.; Harris, J.; Clark, C.G.","year":"1972","unstructured":"Archampong EQ, Harris J, Clark CG.
