Constipation treatment during pregnancy

Pregnancy can slow bowel movement, while iron supplements, nausea-related diet changes and reduced activity may add to the problem. Check any medicine, herbal remedy, enema or supplement with a pharmacist, midwife or doctor before use.

Hormonal changes relax the bowel and can make stool move more slowly. Later, pressure from the growing uterus may add to fullness or difficulty passing stool. Hard stool, straining and a sense of incomplete emptying can occur even when bowel movements have not stopped. Constipation itself does not usually harm the pregnancy, but forceful straining may aggravate haemorrhoids or anal discomfort. Symptoms should still be assessed when they are severe, unusual or accompanied by warning signs.

Sip water regularly unless your maternity team has advised fluid restriction. Add fibre slowly with fruit, vegetables, beans and whole grains, and continue pregnancy-appropriate movement if you have been cleared for it. Sit on the toilet after a meal when the bowel is naturally more active, support your feet on a low stool and avoid prolonged straining. If iron seems to worsen symptoms, ask whether the dose or formulation can be adjusted; do not discontinue it on your own. A clinician may suggest a bulk-forming, osmotic or stool-softening laxative based on your situation.

Contact your maternity team promptly for persistent constipation with significant pain, rectal bleeding, fever or vomiting. Seek urgent assessment for severe or worsening abdominal pain, a markedly swollen abdomen, inability to pass wind, repeated vomiting, fainting, heavy bleeding, vaginal bleeding, leaking fluid, regular tightening or reduced fetal movement when you would normally expect movement. Do not take extra laxative or use an enema to treat these symptoms without clinical direction.

Ask whether iron or another medicine is contributing, which laxative has the most suitable safety profile for your stage of pregnancy, and how long it should be used. Mention pain location, stool appearance, bleeding, vomiting and any pregnancy-related symptoms so the clinician can separate straightforward constipation from a problem needing examination.
