Constipation during pregnancy - Causes & solutions

Helping your digestion

Constipation is a common digestive issue caused by infrequent bowel movements or difficulty in passing stools. It occurs when the stool moves too slowly through the digestive tract, leading to the absorption of excess water and resulting in dry, hard stools that are difficult to pass. 

What are the causes of constipation during pregnancy?

Constipation during pregnancy can be caused by a combination of a few factors. Here are some specific causes:

1. Hormonal changes: Elevated levels of the hormone progesterone can have a relaxing effect on the muscles in the body, including the muscles of the digestive tract. This relaxation can slow down the movement of food through the digestive system, leading to constipation.

2. Pressure on the intestines: As the uterus expands to accommodate the growing baby, it can exert pressure on the intestines. Hence, this pressure can slow down the passage of stool through the colon, leading to constipation.

3. Iron supplements: Iron is often prescribed during pregnancy to present or treat iron-deficiency anaemia. However, iron supplements can be constipating for some women.

4. Prenatal Vitamins: Some prenatal vitamins, especially those containing iron and calcium, can sometimes contribute to constipation. These nutrients are crucial for the health of both the mother and the developing baby, so it’s important to find a balance between meeting nutritional needs and managing constipation.

5. Dehydration: Pregnant women may experience an increased demand for fluids, and dehydration might contribute to constipation. It’s essential to stay well-hydrated during pregnancy.

6. Changes in diet: Pregnancy can bring about changes in dietary habits. If a woman’s diet lacks sufficient nutrients from fruits, vegetables and whole grains, constipation may occur.

7. Reduced Physical Activity: Pregnancy symptoms such as fatigue and physical discomfort may lead to a decrease in physical activity. Regular exercise can help stimulate bowel movements and improve overall digestion.

8. Hemorrhoids: Constipation can lead to straining during bowel movements, which may contribute to the development of hemorrhoids. It may cause pain and discomfort too.

9. Medication: Some medications, including antacids and pain relievers, may contribute to constipation.


It’s important for pregnant women to address constipation in a way that is safe for both the mother and the developing baby. Lifestyle and dietary adjustments, such as increasing fiber intake, staying hydrated, and engaging in regular physical activity, are often recommended. If constipation persists or is severe, it’s advisable for pregnant women to consult with their healthcare provider for personalized advice and guidance such as laxatives in pregnancy. 

Remedies for constipation during pregnancy

Preventing constipation involves adopting lifestyle and dietary habits that promote regular bowel movements. Here are some tips to prevent constipation:

1. Eat a high-fiber diet: Include plenty of fiber-rich foods in your diet, such as fruits, vegetables, whole grains, legumes, and bran cereals. Aim for at least 25 to 30 grams of fiber per day.

2. Stay Hydrated: Drink plenty of water throughout the day. Adequate hydration helps soften stools and supports normal bowel function.

3. Exercise Regularly: Engage in regular, moderate exercise, as recommended by your healthcare provider. Exercise helps stimulate bowel movements and promotes overall digestive health.

4. Establish a regular bathroom routine : Try to go to the bathroom at the same time each day, preferably after meals. The body’s natural reflexes are often most active after eating.

5. Don’t ignore the urge to have a bowel movement: When you feel the urge to have a bowel movement, don’t postpone it. Ignoring the urge can lead to harder stools and constipation.

6. Limit intake of constipating foods: Reduce the consumption of foods that can contribute to constipation, such as processed foods, dairy products and red meat.

7. Consider probiotics: Probiotics are beneficial bacteria that can promote a healthy balance in the gut. They may help regulate bowel movements. Probiotics can be found in some yoghurts or taken as supplements.

8. Be cautious with certain medications: Some medications, including certain pain relievers and antacids, can contribute to constipation. If you are taking such medications regularly, discuss alternatives with your healthcare provider.

9. Consider your iron intake: If you are taking iron supplements and experiencing constipation, talk to your healthcare provider. They may adjust the dosage or recommend dietary changes. 

When should you speak with your doctor?

  • Persistent constipation: If you’ve tried lifestyle and dietary modifications, such as increasing fiber intake, staying hydrated, and exercising, but constipation persists, it’s time to consult your healthcare provider.
  • Severe discomfort or pain: If you experience severe discomfort, pain, or blood in your stool, it's crucial to seek medical attention.
  • New orworsening symptoms: If you notice new or worsening symptoms associated with constipation, such as abdominal swelling, vomiting or weight loss, it’s important to inform your healthcare provider.
  • Medication concerns: If you are considering or already taking over-the-counter medications, including stool softeners or laxatives, it’s crucial to discuss this with your healthcare provider before starting any new medication during pregnancy.
  • Dehydration: If you are experiencing signs of dehydration, such as dark urine, infrequent urination, or extreme thirst, it’s important to seek medical attention.
