What should you know about constipation relief in the first trimester?

Pregnancy hormones can slow bowel movement, while nausea, reduced activity, dietary changes, iron supplements, or vomiting can add to the problem. Constipation may mean hard stools, straining, fewer bowel movements, or a feeling that the bowel has not emptied. It is uncomfortable, but severe pain, vomiting, or inability to pass gas needs a different assessment.

Sip fluids regularly unless your maternity team has advised a restriction. Add fibre gradually through fruit, vegetables, beans, whole grains, or other tolerated foods, and take a short gentle walk if you feel well. Avoid straining and respond to the urge to use the toilet. Do not start laxatives, herbal products, or change iron supplements without checking with your maternity clinician. A nutrition counsellor can help tailor food choices; see [Nutrition Counselling](/treatments/lifestyle-and-wellness/nutrition-counselling/).

Contact your maternity team for persistent constipation, blood on the stool, or symptoms that interfere with eating and drinking. Seek urgent care for severe or one-sided abdominal pain, repeated vomiting, a swollen abdomen, fever, fainting, vaginal bleeding, or inability to pass stool and gas. Very dark urine, dizziness, and a dry mouth can indicate dehydration and need prompt advice.

Ask which fibre or laxative options are suitable, whether an iron preparation is contributing, how much fluid is appropriate for you, and when abdominal symptoms require urgent review.
