Background: Abdominal discomfort is a common complaint by women and may vary with the menstrual cycle. The aim of this study was to investigate abdominal symptoms and general well being of women in relation to different phases of the menstrual cycle as well as gastrointestinal transit time.

Methods: Fourteen young women who were not using any contraceptive medications were recruited. Questionnaire was used to exclude functional gastrointestinal problems. Questionnaires on abdominal symptoms and general well being were used. Gastric emptying time, small intestinal transit time and colonic transit time were measured and serum sex hormone concentrations were measured at three points in the menstrual cycle.

Results: Abdominal symptoms were significantly more pronounced at the beginning of the follicular phase. Gastric emptying and colonic transit times were not significantly different between the follicular and the luteal phase of the menstrual cycle. Small bowel transit was faster in the luteal phase (75,7 min) compared with the follicular phase (99,3 min). There was no correlation between the transit times, symptoms or hormone concentrations.

Conclusions: Results indicate that women experience more abdominal symptoms at the begining of the follicular phase compared to the early luteal phase. Small bowel transit appears to be faster in the luteal phase than in the follicular phase. Further studies on the relationship of gastrointestinal symptoms and the menstrual cycle are needed.
