What is Constipation in Pregnancy?
Constipation is very common in pregnancy, affecting many people at some stage. Rising progesterone levels relax the muscles of the digestive tract, slowing the movement of food through the bowel, while later in pregnancy the growing uterus can add extra pressure. Iron supplements, often recommended during pregnancy, can also contribute.
It usually responds well to simple dietary and lifestyle changes, though it can be uncomfortable and, if persistent, contribute to piles (haemorrhoids).

- 3Stay physically active.Gentle, regular movement like walking supports healthy bowel function.
- 4Don't delay going to the toilet.Respond to the urge when it happens rather than holding it in.
