Medically reviewed by healthcare professionals | Last reviewed: March 2026

📅 When It Occurs

Can begin early pregnancy, typically worsens throughout pregnancy

📊 How Common

Affects 30-40% of pregnant women

Overview

Constipation is one of the most common digestive complaints during pregnancy. You may find yourself going days without a bowel movement, straining when you do go, and passing hard, painful stools.

The combination of hormonal changes slowing your digestive system, prenatal vitamins (especially iron), and your growing uterus putting pressure on your intestines creates the perfect storm for constipation.

Left untreated, constipation can lead to hemorrhoids and anal fissures, both painful conditions. Fortunately, dietary changes and lifestyle modifications can usually provide significant relief.

Can begin early due to hormonal changes and prenatal vitamins

Third Trimester

🔍 What Causes It?

  • Progesterone hormone relaxing intestinal muscles and slowing digestion
  • Iron in prenatal vitamins causing harder stools
  • Growing uterus pressing on intestines and restricting movement
  • Not drinking enough water
  • Not eating enough fiber
  • Reduced physical activity
  • Anxiety about bowel movements making problem worse

💡 Relief Strategies

  • Drink at least 8-10 glasses of water daily, more if possible
  • Eat 25-30 grams of fiber daily (fruits, vegetables, whole grains, beans)
  • Start your day with warm water with lemon to stimulate digestion
  • Eat prunes, prune juice, or dried apricots - natural laxatives
  • Exercise regularly - even a 20-minute walk helps
  • Don't ignore the urge to go - respond promptly
  • Eat smaller, more frequent meals rather than large meals
  • Add ground flaxseed or chia seeds to foods (soaked in water first)
  • Try a fiber supplement like Metamucil (with doctor approval)
  • Consider switching prenatal vitamins if iron is the issue
  • Use a stool softener like Colace (docusate sodium) - safe in pregnancy
  • Establish a regular bathroom routine, ideally after breakfast
