The relationship between colonic motility, sleep, and arousals from sleep has never been studied in women and only once in men. The purpose of this study was to determine how sleep and arousals from sleep affected colonic motility in women during the follicular phase of their menstrual cycle. We monitored sleep and segmental colonic motility in six healthy women during the follicular phase of the menstrual cycle. We observed no colonic motility during sleep; during awake periods or during arousals, we observed isolated low-amplitude bursts of colonic motility. This colonic motility occurred during 25% of the arousal and awakening time. In contrast, morning awakening was associated with high-amplitude independent and related colonic motility in all colonic segments. We conclude that in women in the follicular phase of their menstrual cycle, colonic motility is inhibited during sleep; colonic motility at night only occurs during arousals or awakenings from sleep.
结肠运动、睡眠以及睡眠中觉醒之间的关系在女性中从未被研究过，在男性中也仅被研究过一次。本研究的目的是确定睡眠和睡眠中觉醒如何影响处于月经周期卵泡期的女性的结肠运动。我们在六名健康女性月经周期的卵泡期监测了睡眠和结肠节段性运动。我们观察到睡眠期间无结肠运动；在清醒期或觉醒期间，我们观察到孤立的低幅度结肠运动爆发。这种结肠运动在25%的觉醒和清醒时间出现。相比之下，早晨醒来与所有结肠节段的高幅度独立且相关的结肠运动有关。我们得出结论，处于月经周期卵泡期的女性，睡眠期间结肠运动受到抑制；夜间结肠运动仅在觉醒或从睡眠中醒来时发生。
