Constipation in Pregnancy
Constipation is a silent, bothersome pregnancy symptom. It affects about half of pregnant women at some stage, and may come with bloating, gas, and a feeling of discomfort, increasing the risk of hemorrhoids that trouble many pregnant women. Despite the embarrassment of talking about it, it is a very common problem with clear physiological causes and effective natural solutions in most cases. In this guide we explain why constipation happens specifically in pregnancy, the role of progesterone and iron supplements, its timeline, a practical plan to overcome it with fiber, water, and movement, and when to consult your doctor.
Short answer: Constipation in pregnancy is common and normal, caused by progesterone slowing the intestines, iron supplements, and lack of movement. Its treatment is natural: fiber, enough water, a daily walk, dried prunes, and responding promptly to the urge to go. Avoid strong laxatives without consulting your doctor. See your doctor with severe pain, bleeding, or vomiting.
What Is This Symptom and Why Does It Happen in Pregnancy?
Constipation is difficulty passing stool or going less often than usual, with hard dry stool and the need to strain. In pregnancy it happens because bowel movement slows: progesterone, which maintains the pregnancy, relaxes the smooth muscles of the body, including the intestinal wall muscles, so waste moves more slowly and the colon absorbs more water from it, making it hard. Other factors add up: iron supplements prescribed to most pregnant women cause constipation as a common side effect; lack of physical activity, especially with fatigue and nausea; too little water; dietary changes; and in the later months the growing uterus presses directly on the intestines and rectum, hindering their movement. Ignoring the urge to go because of busyness also worsens the problem.
The science behind it
- Progesterone relaxes intestinal muscles and slows their movement
- Iron supplements prescribed in pregnancy, as a common side effect
- Too little water and too little fiber in the diet
- Lack of movement and physical activity
- The growing uterus presses on the intestines and rectum in the later months
- Ignoring the urge to go and delaying it
When Does It Start and When Does It Get Better?
Constipation may start early in the first trimester with rising progesterone and the start of iron supplements, and continues throughout pregnancy in varying degrees. It usually worsens in the third trimester with uterine pressure on the intestines and less movement due to heaviness. After birth it gradually improves as hormones drop and activity returns, but it may continue in the first weeks, especially with post-birth painkillers and little movement. Early prevention with correct dietary habits from the start of pregnancy avoids much later suffering.
Natural, Safe Ways to Find Relief
- Eat twenty-five to thirty grams of fiber daily: vegetables, fruit with the peel, oats, legumes, and whole-wheat bread
- Drink eight to ten cups of water daily; fiber without enough water may worsen constipation
- Walk thirty minutes daily; movement naturally stimulates bowel activity
- Try dried prunes: five to six a day; they are an effective natural laxative and safe
- Respond to the urge to go immediately and do not delay it; set aside a calm time in the morning
- A cup of warm water on an empty stomach in the morning stimulates bowel movement in many women
- Discuss your iron supplement with your doctor if it causes severe constipation; they may suggest a gentler type or adjusting the dose and timing

Frequently asked questions
Do iron supplements cause constipation?
Yes; constipation is one of the most common side effects of iron supplements. Talk to your doctor; they may suggest a gentler type, taking it with food, or adjusting the dose, without stopping it on your own because iron is essential for you and your baby.
What is the fastest natural laxative for pregnant women?
Dried prunes are among the fastest and safest natural laxatives, along with warm water in the morning and more fiber. Avoid laxative medications without consulting your doctor.
Does severe straining harm the baby?
Occasional straining does not harm the baby; it is protected inside the uterus and amniotic fluid. But repeated severe straining is uncomfortable and may cause or worsen hemorrhoids, so treat constipation early instead of relying on straining.
Does constipation cause hemorrhoids in pregnancy?
Yes; repeated straining with uterine pressure on pelvic veins increases the risk of hemorrhoids. Prevent it by treating constipation early, drinking water, and avoiding long sitting on the toilet.
How much fiber is right for a pregnant woman?
Twenty-five to thirty grams daily from varied sources, increased gradually with enough water; a sudden increase in fiber without water may cause bloating and gas.
