What should you know about constipation before pregnancy?

Hard or infrequent stools can follow a low-fibre diet, low fluid intake, reduced activity, travel or a change in routine. Medicines and supplements can contribute too. Constipation can also occur alongside irritable bowel syndrome or hypothyroidism; these conditions need a clinical assessment rather than self-diagnosis.

Before trying to conceive, note how often you open your bowels, whether you strain, and whether pain or bloating accompanies it. The [Constipation](/symptoms/constipation/) guide can help you describe the pattern at an appointment.

Build fibre up gradually with fruit, vegetables, pulses and whole grains, and drink regularly. Walking or another suitable activity can support bowel movement. Set aside unhurried toilet time and avoid repeatedly ignoring the urge. A food diary may reveal whether a sudden change in fibre or particular foods worsens symptoms.

If you use laxatives, supplements or medicines, ask a clinician or pharmacist whether they should be changed before conception. Do not stop prescribed treatment abruptly. Nutrition Counselling can help create a realistic eating plan for preconception and early pregnancy.

Arrange medical advice if constipation persists despite routine changes, keeps returning, or began after a medicine change. Seek urgent care for severe abdominal pain, repeated vomiting, a distended abdomen, inability to pass gas, blood or black tarry stool, fever, faintness or unexplained weight loss. These features need assessment rather than a pregnancy-safe home remedy.

Ask whether thyroid testing or a medicine review is appropriate, which fibre and fluid targets fit your health, what treatment is compatible with trying to conceive, and what to do if you become pregnant while using a bowel medicine.
