Constipation in the second trimester

Hormonal shifts can slow the bowel during mid-pregnancy. Iron supplements, a change in routine, less exercise, nausea-related food choices or low fluid intake may make stools harder. Constipation commonly causes firm stools, straining, bloating or discomfort around bowel movements.

A new symptom should not automatically be blamed on pregnancy. Severe abdominal pain, fever, repeated vomiting, vaginal bleeding, leaking fluid or feeling faint needs medical advice. Cramping that becomes regular or stronger may need maternity assessment even if constipation is also present.

Drink regularly if your pregnancy team has not limited fluids. Add fibre gradually through foods such as vegetables, fruit, beans or whole grains, and take gentle walks if comfortable. Sit with your feet supported, respond to the urge to open your bowels and avoid forceful pushing.

Check with your midwife, obstetric clinician or GP before taking laxatives, herbal remedies or enemas. They can review iron and other medicines, check for dehydration and select a pregnancy-appropriate treatment. Nutrition counselling can be useful when nausea or food intolerance limits choices.

Seek prompt care for severe or worsening abdominal pain, repeated vomiting, a swollen firm abdomen, blood in the stool, inability to pass gas, faintness or signs of dehydration such as very dark urine and marked thirst. Contact maternity services for bleeding, fluid leakage or regular painful tightening.

Make a routine appointment when constipation persists, returns frequently or affects daily activities. Describe the timing, stool texture, fluid intake and every medicine or supplement you use.

Could my iron supplement or another medicine be causing this? How much fibre, fluid and activity is suitable for me? Which treatment is safe in pregnancy? Do my cramps or bowel symptoms need an examination?
