Prospective Study of the Effect of Coffee Consumption in Enhancing Recovery of Bowel Function Following Colorectal Surgery.

Detailed Summary

The effects of coffee have been shown to act as a colonic stimulant. Caffeinated coffee stimulates colonic activity, most notably in the transverse/descending colon, in magnitude similar to a meal, 60% stronger than water, and 23% stronger than decaffeinated coffee. \[1\] Moreover, the consumption of both water and caffeine causes a decrease in the rectal sensory threshold for the desire to defecate, while anal sphincter pressure after caffeine intake is significantly higher than after water intake. This may result in an earlier desire to defecate. \[2\] Coffee has also been shown to have an effect on defecation by increasing rectal tone by 45% (measured with a barostat) thirty minutes after consumption. \[3\]
