Constipation during pregnancy: what can you take?

Pregnancy hormones can slow movement through the bowel. A growing uterus, reduced activity, changes in diet, iron supplements, and not drinking enough can add to the problem. Hard stools, straining, bloating, or fewer bowel movements can all occur.

Constipation itself does not automatically indicate a pregnancy complication. However, a clinician should consider other contributors if it is persistent, severe, or accompanied by unusual symptoms. Dehydration, hypothyroidism, and irritable bowel syndrome can also affect bowel habits.

Sip water throughout the day if you have no fluid restriction. Build fibre slowly with vegetables, fruit, oats, whole grains, beans, and seeds, and keep moving with comfortable walking or pregnancy-approved activity. Use the toilet when you feel the urge; a small footrest can make the position more comfortable.

If these measures are not enough, ask your obstetric clinician or pharmacist about a pregnancy-suitable stool softener or laxative. Do not start herbal products, stimulant laxatives, or someone else’s medicine without checking first. If iron appears to worsen constipation, ask whether the formulation or timing can be changed rather than stopping it yourself.

Arrange advice when constipation persists, repeatedly returns, or interferes with eating, sleeping, or daily activity. Seek urgent assessment for severe abdominal pain, persistent vomiting, a markedly swollen abdomen, inability to pass gas, blood in the stool, fever, faintness, or symptoms of dehydration. During pregnancy, contact your maternity service as well for bleeding, fluid loss, regular painful contractions, or reduced fetal movement.

Ask which fibre or bowel medicine is appropriate for your stage of pregnancy, how it fits with prenatal vitamins and iron, and how long to try it. Tell the clinician about pain, vomiting, bleeding, and your usual bowel pattern.
