Dealing with constipation during pregnancy can feel uncomfortable and frustrating. The good news is that you’re not alone—up to 40% of pregnant women experience this common digestive issue at some point during their nine months.
Your changing hormones, growing uterus, and prenatal vitamins all contribute to slower digestion. But before you reach for over-the-counter remedies, it’s important to know which solutions are safe for both you and your baby.
This guide covers proven, pregnancy-safe methods to find relief naturally and when medical intervention might be necessary.

Why Constipation Happens During Pregnancy
Pregnancy hormones work against your digestive system in several ways. Progesterone relaxes smooth muscle tissue throughout your body, including your intestines, which slows down the movement of food through your digestive tract.
As your pregnancy progresses, your expanding uterus puts physical pressure on your intestines. This mechanical compression makes it harder for waste to move through efficiently.
Iron supplements in prenatal vitamins are another common culprit. While essential for preventing anemia, iron can be binding and significantly slow down bowel movements.
Simple Dietary Changes That Work
Fiber is your first line of defense against pregnancy constipation. Most pregnant women need between 25-30 grams of fiber daily, but many fall short of this target.
Best High-Fiber Foods for Pregnancy
- Raspberries, pears, and apples with skin (3-5 grams per serving)
- Lentils, black beans, and chickpeas (8-15 grams per cup)
- Whole grain bread and oatmeal (3-4 grams per serving)
- Chia seeds and ground flaxseed (5-10 grams per tablespoon)
- Broccoli, Brussels sprouts, and sweet potatoes (3-4 grams per serving)
Start increasing fiber gradually to avoid gas and bloating. Your digestive system needs time to adjust to higher amounts.
Prunes deserve special mention. They contain sorbitol, a natural sugar alcohol that draws water into your intestines and stimulates contractions. Just 3-4 prunes or half a cup of prune juice daily can make a noticeable difference.
The Water Factor Everyone Overlooks
Fiber without adequate water can actually make constipation worse. Think of fiber as a sponge that needs liquid to work properly.
Aim for at least 8-10 glasses of water daily during pregnancy, and increase this if you’re active or live in a hot climate. If plain water feels boring, try infusing it with lemon, cucumber, or berries.
Warm liquids in the morning can be particularly effective. A cup of warm water with lemon or herbal tea upon waking can stimulate your digestive system and encourage morning bowel movements.
Movement Makes Everything Move
Regular physical activity helps food move through your digestive tract more efficiently. You don’t need intense workouts—gentle movement is enough.
Walking for just 20-30 minutes daily can significantly improve constipation. The rhythmic motion and upright position both encourage bowel activity.
Prenatal yoga includes specific poses that gently massage your digestive organs. Cat-cow stretches, child’s pose, and seated twists (modified to avoid compressing your belly) can all help.
Swimming and prenatal water aerobics provide excellent low-impact options that take pressure off your joints while keeping things moving internally.
Safe Over-the-Counter Solutions
Sometimes lifestyle changes aren’t enough, and that’s okay. Several over-the-counter options are considered safe during pregnancy.
Bulk-Forming Fiber Supplements
Psyllium husk (Metamucil) and methylcellulose (Citrucel) are generally regarded as the safest first-line treatments. They work by adding bulk to stool and drawing in water, mimicking natural dietary fiber.
Take these supplements with plenty of water—at least 8 ounces per dose—and start with a lower dose to assess tolerance.
Stool Softeners
Docusate sodium (Colace) is widely considered safe throughout pregnancy. It works by allowing water and fats to penetrate stool, making it softer and easier to pass.
These typically take 1-3 days to work, so patience is required. They’re particularly helpful if you’re taking iron supplements.
Osmotic Laxatives
Polyethylene glycol (MiraLAX) draws water into your colon to soften stool. Studies show it doesn’t enter your bloodstream significantly, making it a safe option for occasional use.
Magnesium-based laxatives like milk of magnesia can also work, but check with your healthcare provider first, especially if you have kidney issues or preeclampsia risk factors.
What to Avoid During Pregnancy
Not all constipation remedies are pregnancy-safe. Stimulant laxatives like bisacodyl (Dulcolax) and senna should be avoided or used only under medical supervision.
These products can cause uterine contractions and may lead to dependency if used regularly. Mineral oil should also be avoided as it can interfere with nutrient absorption.
Castor oil is particularly risky during pregnancy. It can trigger strong intestinal contractions and potentially stimulate labor, making it unsafe at any stage.
Creating a Bathroom Routine That Helps
Your body thrives on consistency. Try to use the bathroom at the same time each day, preferably after breakfast when your digestive system is naturally most active.
Don’t ignore the urge to go. Delaying bowel movements can lead to harder stools that are more difficult to pass later.
Using a footstool to elevate your feet while sitting on the toilet changes the angle of your rectum, making elimination easier. This squatting position is more natural and requires less straining.
Adjusting Your Prenatal Vitamins
If your prenatal vitamin seems to be contributing to constipation, talk to your healthcare provider about alternatives. Some brands are easier on the digestive system than others.
Taking your prenatal vitamin with food, particularly in the evening rather than morning, can sometimes help. Splitting the dose throughout the day is another option for some formulations.
Your doctor might recommend a lower-iron prenatal vitamin if your iron levels are adequate, or suggest taking iron separately so you can adjust timing and dosage.
When to Call Your Healthcare Provider
Most pregnancy constipation resolves with simple interventions, but certain symptoms warrant medical attention.
Contact your provider if you haven’t had a bowel movement in more than three days despite trying home remedies. Severe abdominal pain, cramping, or blood in your stool also require immediate evaluation.
If you’re experiencing nausea, vomiting, or significant abdominal swelling along with constipation, don’t wait. These could indicate a more serious issue requiring medical treatment.
Persistent constipation that doesn’t respond to dietary changes and safe over-the-counter treatments may need prescription medication or further investigation.
Prevention Strategies for Long-Term Relief
The best approach to pregnancy constipation is preventing it before it becomes problematic. Start implementing these strategies early in pregnancy, even before symptoms appear.
Build your fiber intake gradually from the first trimester. This gives your digestive system time to adapt as hormones change throughout pregnancy.
Keep a food and symptom diary to identify which foods help or hinder your digestion. Everyone’s body responds differently, and patterns will emerge over time.
Stay ahead of dehydration by carrying a water bottle everywhere. Small sips throughout the day work better than chugging large amounts at once.
Frequently Asked Questions
Is it safe to use suppositories during pregnancy?
Glycerin suppositories are generally considered safe for occasional use during pregnancy. They work locally in the rectum and aren’t absorbed into your bloodstream. However, check with your healthcare provider before using any suppository regularly, especially in the third trimester.
Can constipation harm my baby?
Constipation itself won’t harm your baby, but excessive straining can be uncomfortable and may contribute to hemorrhoids. Severe, untreated constipation can lead to complications like fecal impaction, which requires medical intervention. Addressing the issue promptly keeps both you and baby more comfortable.
How quickly should natural remedies work?
Dietary changes typically take 2-3 days to show noticeable improvement. Increased water intake and exercise may work slightly faster. If you don’t see any improvement after one week of consistent lifestyle modifications, it’s time to consider other options with your healthcare provider.
Why does constipation get worse in the third trimester?
Your growing baby takes up more space, putting increased pressure on your intestines and rectum. This physical compression, combined with peak progesterone levels and reduced physical activity as pregnancy advances, creates the perfect storm for worsening constipation.
Can I drink coffee to help with constipation during pregnancy?
A small amount of coffee (under 200mg caffeine daily) is generally considered safe during pregnancy and may stimulate bowel movements. However, coffee is also mildly dehydrating, so increase your water intake accordingly. Decaf coffee can provide similar digestive benefits without the caffeine concerns.
Will constipation affect my labor and delivery?
Having constipation during labor is common and won’t prevent you from delivering your baby. Many women naturally empty their bowels during early labor. If you’re severely constipated near your due date, gentle remedies or an enema may be recommended to improve comfort.
Are probiotics safe and helpful for pregnancy constipation?
Probiotics are generally safe during pregnancy and may improve digestive function for some women. Look for pregnancy-safe strains like Lactobacillus and Bifidobacterium. While research on their effectiveness for constipation is mixed, they offer other health benefits and are worth discussing with your provider.
Should I be worried if I only go every few days?
Bowel movement frequency varies by individual. If you’re going every 2-3 days without discomfort, hard stools, or straining, this may be normal for you during pregnancy. However, if this represents a significant change from your pre-pregnancy pattern or causes discomfort, it’s worth addressing with dietary and lifestyle modifications.
