Gas and constipation in pregnancy

Hormonal changes can relax bowel muscles and slow the movement of stool. As pregnancy progresses, the growing uterus can also reduce room for the bowel. Iron supplements, reduced activity, altered eating patterns and nausea-related fluid loss may add to constipation. Gas can cause cramping, rumbling and a stretched feeling, but pregnancy pain should not automatically be labelled digestive. Irritable bowel syndrome, dehydration and other conditions can overlap with these symptoms.

Sip fluids regularly, eat fibre-containing foods as tolerated, and add fibre in small increases to avoid extra bloating. Gentle walking can support bowel movement if your maternity team says activity is appropriate. Try relaxed toilet time and do not strain. Do not start laxatives, herbal products or antacids without checking with your obstetric clinician or pharmacist; they can consider your pregnancy, other medicines and medical history. Nutrition Counselling can help tailor meals when nausea or food aversions make eating difficult.

Get urgent advice for severe or one-sided abdominal pain, persistent vomiting, fever, faintness, vaginal bleeding, fluid leakage, painful regular tightenings, or inability to pass stool and gas with increasing swelling. Contact your maternity team if constipation persists, pain is new, or you are unsure whether a symptom is digestive. Mention any supplement changes, including iron, during the assessment.

Is my iron supplement contributing, and can its formulation be changed? Which fibre or laxative options are suitable for me? Which abdominal symptoms should be reported immediately?
