What should you know about laxative for pregnancy constipation?

Pregnancy hormones, reduced movement, pressure from the growing uterus and iron supplements can slow bowel movements. Constipation may mean hard stools, straining or feeling unable to empty fully. It is not a reason to stop prescribed iron without advice.

Clinicians often begin with fluids, gentle activity and fibre if these suit you, then consider a laxative that works by softening stool or drawing water into the bowel. A clinician should check severe, persistent or unusual symptoms first. Other conditions, including hypothyroidism or irritable bowel syndrome, can affect bowel habits.

Drink regularly unless you have been told to restrict fluids. Add fibre gradually from foods such as vegetables, fruit, pulses and whole grains, and take short walks if your maternity team says activity is appropriate. Sudden fibre increases without enough fluid can worsen discomfort.

Ask a pharmacist or maternity clinician before using a laxative, herbal product or someone else’s medicine. Follow the label or prescription directions, and tell them about supplements and other medicines. Nutrition counselling can help tailor food choices when constipation keeps returning.

Seek urgent advice for severe or one-sided abdominal pain, repeated vomiting, a swollen abdomen, blood in the stool, faintness, inability to pass gas, or signs of dehydration. Contact your maternity team for new bleeding, painful contractions or concerns about your pregnancy.

Could my iron supplement be contributing? Which option fits my pregnancy and other medicines? How long should I try it? What symptoms mean I should stop and call the maternity team?
