Effect of alcohol consumption on the gut.

Bode, Christiane, Christian Bode, J·2003·Best Practice & Research Clinical Gastroenterology

Abstract

Consumption of large quantities of alcoholic beverages leads to disturbances in the intestinal absorption of nutrients including several vitamins. The inhibition of the absorption of sodium and water caused by alcohol contributes to the tendency in alcoholics to develop diarrhoea. Excessive alcohol consumption (even a single episode) can result in duodenal erosions and bleeding and mucosal injury in the upper jejunum. An increased prevalence for bacterial overgrowth in the small intestine may contribute to functional and/or morphological abnormalities of this part of the gut and also to non-specific abdominal complaints in alcoholics. The mucosal damage caused by alcohol increases the permeability of the gut to macromolecules. This facilitates the translocation of endotoxin and other bacterial toxins from the gut lumen to the portal blood, thereby increasing the liver's exposure to these toxins and, consequently, the risk of liver injury. The results of recent experimental studies support the assumption that alcohol significantly modulates the mucosal immune system of the gut.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
