How to avoid constipation during pregnancy

Respond when you feel the urge to open your bowels. If these measures are insufficient, a maternity clinician or pharmacist can recommend a laxative that is appropriate for your stage of pregnancy.

Pregnancy hormones can slow movement through the gut, allowing stools to become drier. Later, the growing uterus can add pressure, while reduced activity, nausea-related diet changes and some supplements may add to the problem.

Constipation can mean infrequent stools, hard or lumpy stools, straining, or a sense that the bowel has not emptied fully. Iron supplements are a frequent contributor, but you should not stop prescribed iron without discussing an alternative preparation or dose with your maternity team.

Include vegetables, fruit, pulses and whole grains as tolerated, adding fibre step by step so gas and cramps do not flare. Drink regularly, especially in hot weather or when exercising. Walking and other pregnancy-appropriate activity can stimulate bowel movement.

Allow time after a meal to sit without rushing. A small foot support can raise the knees and reduce straining. Avoid herbal remedies, castor oil, enemas or over-the-counter laxatives unless a qualified clinician confirms they are suitable during pregnancy.

Contact your maternity service for constipation that remains troublesome despite self-care, or if you notice rectal bleeding, persistent abdominal pain, fever, vomiting, inability to pass gas, or a sudden marked change in bowel habits.

Get urgent help for severe abdominal pain, heavy bleeding, fainting, repeated vomiting or pregnancy-specific concerns such as vaginal bleeding, fluid leakage, regular painful tightenings or reduced fetal movement.

Bring a list of supplements and medicines and ask whether any may be slowing your bowel. Discuss how much fibre suits your current diet, which laxative type is compatible with pregnancy, and when persistent constipation should prompt examination or testing.
