What causes pregnancy constipation

With pregnancy comes a number of changes to your body. For many moms-to-be, constipation is one of the symptoms of pregnancy.

If you’re experiencing infrequent or uncomfortable bowel movements. -- in other words, constipation -- don’t worry. This is quite common during pregnancy for many different reasons, which we’ll explain.

Learn what can cause constipation during pregnancy and what you can do to alleviate or prevent the discomfort.

What Causes Constipation in Pregnancy?

Constipation can happen at any time in life, but you may be more susceptible to this condition during the later stages of pregnancy, perhaps when you’re in the third trimester. The potential causes of constipation at this time include:

  • Having higher levels of the hormone progesterone, which can slow down digestion

  • Taking iron supplements, which can irritate your digestive tract

  • Physical changes such as the weight of your uterus putting pressure on your rectum, which can worsen constipation if you already have it.

Prevention and Home Remedies

Having infrequent bowel movements or stools that are difficult to pass can be quite uncomfortable even at the best of times, but these symptoms of constipation can be even more unpleasant when you’re pregnant and dealing with a host of other aches and pains.

You may wish there were a miracle cure, or a medical formula, for immediate relief from your pregnancy constipation, but unfortunately there isn’t. Instead, focus on changes you can make to your diet and levels of activity, which may get things moving in time.

Here are some you can take to help prevent or relieve constipation during pregnancy:

  • Drink lots of fluids, such as water, prune juice, and other 100 percent fruit juices.

  • Consume high-fiber foods, aiming for at least 25 grams per day. Include vegetables, fruits, beans, whole-grain products, and bran cereal in your diet. Increasing your fiber intake suddenly can cause a side effect of excess gas, so take care to eat your meals slowly and avoid swallowing too much air. Also, avoid carbonated drinks and chewing gum to help prevent a build-up of gas.

  • Exercise regularly. Check with your healthcare provider to find out what you can safely do. Even simply walking more can help encourage your digestive system to get going.

  • Instead of eating three large meals a day, eat smaller meals more frequently throughout the day to make the food easier to digest.

If you’re finding that the lifestyle changes listed above don’t work for you, turn to your healthcare provider. Your provider may recommend one of these over-the-counter medications, which can help you pass hard stools, but are not a cure for constipation:

  • A bulk-forming agent, which works by absorbing water and adding moisture to your stool to make it easier to pass. Make sure to drink extra fluids if you’re taking this medication.

  • A stool softener, which adds liquid to your stool to soften it

  • A stimulant, which uses a chemical to stimulate intestinal activity.

Potential Complications of Constipation

If the symptoms of constipation persist for several weeks or longer, this indicates chronic constipation, which can lead to complications such as:

  • Hemorrhoids, which are swollen veins in your anus

  • Anal fissures, which are tears of the skin in your anus

  • Fecal impaction, which is when hardened stool accumulates in your intestines

  • Rectal prolapse, which is when your rectum protrudes from the anus.

To help avoid complications, it’s safest to get in touch with your healthcare provider at the first signs of constipation or pain.

Don’t let constipation ruin your last few months of pregnancy! Talk to your healthcare provider, and make some of the lifestyle changes we’ve listed in this article. In time, things will get moving down there, and you can get back to more enjoyable tasks such as shopping for baby gear, decorating your baby’s nursery, or even just putting your feet up for a bit.

One thing to keep in mind is that, at the other end of the spectrum, you may experience diarrhea from time to time during your pregnancy. You should always mention this to your healthcare provider, especially if you suspect it may be caused by something like food poisoning or a tummy bug.

Constipation is very common in pregnancy. It means that your bowel motions (poos) are very hard and may be painful to pass. You may also be doing a poo less often than usual.

There are things you can do to help deal with constipation and prevent it.

Symptoms of constipation

Symptoms include:

  • hard stool (poo)
  • less frequent bowel motions (pooing less)
  • pain on passing a bowel motion (when having a poo)
  • passing wind (farting)
  • cramp-like pains in your tummy

Causes of constipation

Constipation can be caused by:

  • not drinking enough water
  • not eating enough fibre
  • pregnancy hormones - these can make your poo move more slowly through your intestine
  • your growing baby and womb putting extra pressure on your intestines
  • taking iron supplements

How to ease constipation

You can ease constipation by:

  • drinking plenty of water - try to have 10 glasses of water a day, about 2.3 litres
  • eating foods that are high in fibre every day - vegetables, wholegrain breads, porridge, fruit, dried fruits, vegetables, beans and lentils
  • staying active - try walking, swimming, pregnancy yoga or pilates
  • going to the toilet when you first feel the urge to have a bowel motion (do a poo) - give yourself plenty of time and take some deep breaths to help relax the pelvic floor

Only take iron supplements if your GP or midwife has said you need them.

Your position on the toilet

Having a good position on the toilet can help when you are emptying your bowels.

  1. Use a small step or footstool under your feet. This helps you to get into the best position.
  2. Lean forward, as much as your bump allows. Put your elbows on your knees. Try and keep your back straight.
  3. Do not strain, and do not hold your breath. Taking long, slow, deep breaths through your mouth will help your tummy muscles relax.
