Official title

Effect of Menstrual Cycle and Irritable Bowel Syndrome on the Central Nervous System Processing of Gut Stimuli

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The hypothesis of the study is that women perceive intestinal stimulation (rectal balloon distention) differently in different phases of the menstrual cycle, i.e there is an effect of hormones on the sensory pathway, and that this difference is reflected in the Central Nervous System processing of this signal. We also hypothesize that there is a difference in perception between control subjects and subjects with the irritable bowel syndrome.
