Diarrhoea after a C-section: what to know

Bowel changes after caesarean birth can follow antibiotics, pain medicines, a change in eating, a stomach infection or the return of normal bowel movement after constipation. Hormonal and physical changes around birth can also affect digestion. Diarrhea does not usually come from the incision itself. A clinician may need to consider infection if you also have fever, worsening abdominal pain, foul-smelling discharge or feeling increasingly unwell. Recovery after a Caesarean Section can involve several body systems, so mention bowel symptoms at your postnatal review.

Sip water or oral rehydration fluid regularly and eat small, gentle meals as tolerated. Keep taking prescribed medicines unless the maternity team tells you otherwise, but ask whether a recent antibiotic or laxative could be contributing. Protect your incision while using the toilet and wash your hands thoroughly. Record stool changes, vomiting, temperature, urine output and medicines taken. Do not use anti-diarrhea products or supplements without checking their suitability after birth, especially if breastfeeding. Gradual movement may support recovery; Postnatal Physiotherapy can help with safe physical rehabilitation when appropriate.

Seek urgent help for fainting, confusion, inability to drink, very little urine, blood or black stool, severe abdominal pain, heavy bleeding, breathing difficulty or a high fever. Contact your maternity team promptly if the wound becomes more red, swollen, painful or starts draining, or if diarrhea continues and you feel weak. A headache, visual disturbance or sudden swelling also deserves urgent advice because postnatal complications such as Pre-eclampsia can occur after birth and should not be dismissed as a bowel problem.

Ask whether your medicines could be causing diarrhea, how much fluid you should take, whether testing is needed, and which symptoms suggest wound or uterine infection. If you are breastfeeding, ask which treatments are compatible with feeding your baby.
