Summary

This study tests whether taking psyllium or fructooligosaccharide (two types of fiber) for six days improves bowel function in women with constipation. Twenty-five women will try each fiber and a control, keeping a diary and having a scan to measure how fast food moves through their gut. The goal is to see which fiber works better and if they cause side effects.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: psyllium powder and fructooligosaccharide (dietary fibers)
What this could lead to: If it works, this could show that simple fiber supplements help women with constipation have more regular bowel movements.
What could go wrong: This is a very small, short-term study (25 women, 6 days per fiber). Results may not apply to everyone, and fibers can cause bloating or gas.
