Background. Alcohol ­abusers fre­quently ­have gas­troin­tes­tinal symp­toms, ­such as diar­rhea, ­nausea and vom­iting. In the gen­esis of ­these symp­toms mul­tiple mech­a­nisms are ­involved, ­including alter­a­tion of gas­troin­tes­tinal ­motility. The aim of our ­study was to inves­ti­gate oro-­cecal ­transit ­time (­OCTT) ­using the H2-­breath ­test (H2-BT) in mod­erate and ­heavy ­drinkers.
Materials and ­methods. We ­studied 40 ­chronic ­drinkers: 20 ­with ­heavy ­alcohol con­sump­tion (≥60 g/day for men and ≥40 g/day for ­women) and 20 ­with mod­erate ­alcohol ­intake (<60 g/day for men and <40 g/day for ­women). The con­trol ­group con­sisted of 20 tee­total sub­jects. All sub­jects under­went a lac­tu­lose H2-BT to ­assess ­OCTT.
Results. ­OCTT in ­heavy ­alcohol ­drinkers ­ranged ­from 100 to 240 ­min, ­with a ­mean of 149.5 ­min, ­while ­OCTT in mod­erate ­drinkers ­ranged ­from 70 to 140 ­min, ­with a ­mean of 109 ­min. In the con­trol ­group the ­mean ­OCTT was 100 ­mins, ­ranging ­from 70 to 130 ­min. The dif­fer­ence ­between ­alcohol ­abusers and con­trols was sta­tis­ti­cally sig­nif­i­cant; on the con­trary, ­there was no sta­tis­ti­cally sig­nif­i­cant dif­fer­ence ­between mod­erate ­alcohol ­drinkers and tee­to­tal­lers.
Conclusions. Our ­study ­shows ­that ­only in ­chronic ­heavy ­alcohol ­drinkers is ­OCTT ­clearly ­increased. Multiple mech­a­nisms are hypoth­e­sized to ­explain ­motility dis­order, ­such as vis­ceral auto­nomic neu­rop­athy, inflam­ma­tion and ­loss of con­trac­tile pro­teins of ­smooth ­muscle ­layer of the ­small intes­tine.
