You can have a bowel movement every day and still be constipated if you have to strain or if you feel an incomplete evacuation, a discomfort often caused by a lack of appropriate fiber.

The fact that constipation is not limited to frequency is entirely accurate. According to Rome IV criteria (expert consensus), symptoms such as straining or the sensation of incomplete evacuation characterize constipation, even with daily transit. Regarding fiber, a meta-analysis of randomized controlled trials (RCT) published in the American Journal of Clinical Nutrition confirms that fiber intake, particularly soluble fiber, significantly improves stool consistency and facilitates transit. However, stating that a lack of specific fibers is the number one cause is a simplification. Observational studies show that hydration, physical activity, and pelvic muscle dynamics play an equally decisive role in these sensations of blockage.
