Constipation for Pregnant Women: What to Know

Pregnancy hormones can slow the bowel, so stools stay in the colon longer and become firmer. Nausea, a lower appetite, less exercise, dietary changes, and iron-containing supplements can contribute. You may notice hard stools, straining, bloating, or an incomplete feeling after using the toilet.

This symptom is not a diagnosis of a pregnancy complication. If it persists, a clinician may consider contributors such as dehydration, irritable bowel syndrome, or an underactive thyroid alongside your other symptoms and medicines.

Keep fluids available and drink regularly, unless your clinician has advised otherwise. Build fibre slowly with vegetables, fruit, beans, lentils, oats, and whole grains. Gentle walking can help bowel movement when it feels comfortable. Try not to ignore the urge to pass stool, and avoid forceful pushing.

Ask a doctor or pharmacist before taking a laxative, stool softener, suppository, herbal product, or supplement marketed for constipation. If an iron tablet appears to be contributing, ask your maternity team about options rather than stopping it independently. Nutrition counselling can support a manageable eating plan.

Speak with your maternity clinician when constipation is persistent, keeps returning, or prevents normal eating and activity. Seek urgent assessment for severe abdominal pain, repeated vomiting, a swollen abdomen, inability to pass gas, blood or black stool, faintness, or vaginal bleeding. Very dark urine, severe thirst, or a clear reduction in urination can signal dehydration.

Could my supplement or another medicine be contributing? What treatment is suitable during my pregnancy? How can I increase fibre without worsening nausea or bloating? Which symptoms should prompt same-day care?
