Key takeaway

This analysis used data from a trial of 338 women with overweight or obesity and urine leaks, who were assigned to a weight-loss programme or a comparison group. Bowel leak severity was scored over 18 months. Among women with liquid stool leaks, losing at least 5 kg went with fewer leaks, as did eating 10 g more fibre a day.

What this study does not show

This compares women by how much weight they lost, not by trial group, so it shows an association, not proof of cause. Only about 1 in 8 women improved, and all had urine leaks to start with.
