Pregnancy brings many changes to your body, and digestive discomfort is one of the earliest and most common. If you've been feeling bloated, heavy, or struggling with bowel movements, you're not alone. Many expecting mothers ask, " When does constipation in pregnancy start, and how long does it last?

Constipation in pregnancy can start as early as the 2nd to 3rd month (around weeks 6–12), mainly due to rising progesterone levels. It often continues throughout pregnancy and may become more noticeable in the second and third trimesters as the growing uterus puts pressure on the intestines.

For over two decades, Miracles Healthcare has been a familiar name for family-centred maternity care in Gurgaon. Backed by a team of 150+ specialists and a strong focus on safe, personalised pregnancy journeys, our gynaecologists guide expecting mothers through every common discomfort, including constipation, with practical, evidence-based advice.

When Does Constipation Start in Pregnancy?

Constipation can begin at different stages for different women, but here's a general timeline:

  • Early Pregnancy (Weeks 6–12): Many women experience constipation as one of the earliest pregnancy symptoms, even before they confirm pregnancy.

  • Second Trimester (Weeks 13–26): Hormonal changes continue, and constipation may worsen due to iron supplements.

  • Third Trimester (Weeks 27–40): The growing baby presses against the intestines, slowing digestion further.

In short, constipation can start as early as 4–6 weeks into pregnancy and may persist on and off until delivery.

Why Does Constipation Happen During Pregnancy?

Several factors contribute to constipation during pregnancy:

1. Rise in Progesterone Hormone

Progesterone relaxes the muscles in your body, including those in the digestive tract. This slows down digestion, allowing more water to be absorbed from food, which makes stools harder.

2. Iron and Calcium Supplements

Prenatal vitamins are essential, but iron supplements can cause hard stools and bloating, making constipation worse.

3. Growing Uterus

As your baby grows, the uterus puts pressure on the rectum and intestines, slowing bowel movements.

4. Reduced Physical Activity

Many women reduce exercise during pregnancy, which can also slow digestion.

5. Low Fibre and Water Intake

Diet plays a big role. Low water intake, processed foods, and a lack of fibre can trigger constipation.

6. Stress and Anxiety

Pregnancy can be emotionally overwhelming, and stress can affect gut movement.

Common Symptoms of Constipation in Pregnancy

You may be experiencing pregnancy-related constipation if you notice:

  • Fewer than 3 bowel movements per week

  • Hard, dry, or lumpy stools

  • Straining while passing stools

  • Feeling of incomplete bowel emptying

  • Bloating and abdominal discomfort

  • Gas and acidity

  • Loss of appetite.

Is Constipation in Early Pregnancy a Sign of Pregnancy?

Yes, constipation is often one of the early signs of pregnancy, alongside nausea, fatigue, and breast tenderness. It usually appears around the time of a missed period due to rising hormone levels.

However, constipation alone is not a confirmed sign of pregnancy. A urine test or blood test, followed by an ultrasound, is needed for confirmation.

How Long Does Constipation Last in Pregnancy?

For many women, constipation continues on and off throughout pregnancy. It may ease in some weeks and return in others. After delivery, it usually settles within a few weeks, although postpartum constipation is also common.

How to Get Relief from Constipation During Pregnancy

The good news is that pregnancy constipation can be managed safely with simple lifestyle changes.

1. Increase Your Fibre Intake

Add these fibre-rich foods to your daily diet:

  • Whole grains (oats, brown rice, whole wheat)

  • Fresh fruits (apple, pear, papaya, only if ripe and approved, guava)

  • Leafy greens and vegetables

  • Pulses and legumes

  • Flaxseeds and chia seeds

2. Drink Plenty of Water

Aim for 8–12 glasses of water daily. Warm water in the morning can help stimulate bowel movements.

3. Stay Physically Active

Gentle activities such as walking, prenatal yoga, and stretching help keep your digestive system moving.

4. Eat Smaller, Frequent Meals

Large meals can strain digestion. Smaller, more frequent meals are easier on your stomach.

5. Don't Ignore the Urge

Going to the toilet as soon as you feel the urge prevents stools from becoming harder.

6. Discuss Your Iron Supplements

If iron is worsening your constipation, your gynaecologist may suggest a different formulation or adjust the dosage.

7. Try Natural Remedies (With Doctor's Approval)

  • Soaked raisins or prunes

  • A spoon of ghee in warm milk at night

  • Stewed apples or pears

  • Isabgol (psyllium husk), only if recommended by your doctor.

Foods to Avoid for Constipation Relief

Limit or avoid these foods that may worsen constipation:

  • Processed and fried foods

  • White bread, maida, and refined flour items

  • Excess dairy products

  • Bananas (in some cases)

  • Caffeine and aerated drinks

  • Spicy and oily food.

When to See a Doctor for Pregnancy Constipation

Mild constipation is normal, but consult your gynaecologist if you experience:

  • Severe abdominal pain or cramping

  • Blood in stools

  • Constipation lasting more than a week

  • Painful piles or haemorrhoids

  • Alternating constipation and diarrhoea

  • Vomiting along with constipation

Untreated constipation can lead to haemorrhoids, anal fissures, and unnecessary discomfort during pregnancy.
