Lactulose is a type of sugar that the body typically digests and absorbs. But some people with liver disease are unable to properly metabolize lactulose. High levels of lactulose in the blood may result from this, which may have detrimental effects on one's health. For the treatment of constipation and other digestive issues, lactulose is frequently used. It can also be used as a laxative on occasion. This article is meant to provide users of Welzo with information about lactulose.

Lactulose is converted to short-chain fatty acids (SCFAs) in the colon by bacteria, which are then absorbed. Within 72 hours, 95% of an oral dose is excreted as SCFAs in the feces, while only 1% is eliminated in the urine.
