Abstract：
:Circadian dynamics of rectal reactivity was studied in humans with regular and irregular rhythms of bowel evacuation function by chronoenterography. In individuals with regular rhythm of this function (stool 7 days per week) the acrophase of circadian rhythm of rectal reactivity was observed in morning hours, while in the daytime and evening and this parameter decreased almost 7-fold. In subjects with bowel arrhythmia (3-6 days with stool per week) rectal reactivity was inversed: 2-fold decreased in the morning and 3-fold increased in the evening.
