Physical Changes In Pregnancy - Bowel Changes

Bowel changes are common in pregnancy. There may be points of regularity that change quickly into constipation and back to diahrrhea. Just when you feel you have figured your body out, it changes again. Changes in hormones, dietary changes, and bodily changes can drastically affect the bowels.


At least half of all women are constipated at some point during pregnancy. Changes in hormones slow food's passage through your body. During the last part of pregnancy, your uterus may press on your rectum. This may add to the problem. Symptoms of constipation include hard, dry stools, bloating, and straining. You may also have gas or stomach pain.

Some things may help: 

  • Drink lots of liquids. Include fruit juices, such as prune juice. 

  • Eat foods high in fiber, such as raw fruits and vegetables and bran cereals. 

  • Exercise each day—just walking is fine. 

  • Take a good quality probiotic

  • Take digestive enzymes

  • Take magnesium citrate daily


 Changes in hormones can also lead to diarrhea. The hormone relaxin that contributes to loosen the pelvis to prepare the birth can also relax the intestines leading to diarrhea. Diarrhea is not usually harmful but can cause influx in electrolytes and can cause dehydration. Dehydration can lead to contractions.

Some things may help:

  • Increase hydration

  • Eat the brat diet (bannanas, applesauce, toast, and rice)

  • Increase electrolytes

  • Take activated charcoal

  • If you are on magnesium, stop taking it

Unusal Patterns in Stool

Changes in color in your stool may occur throughout pregnancy as you consume different types of vitamins and minerals to help support your pregnancy. Different types of foods such as beets or leafy greens may change color and consitency.

Very dark stools can occur during pregnancy, but if you are concerned by color or frequency, always reach out to your health care provider.

Blood in Your Stool

Blood in your stool may occur from straining when constipated.Hemorrohids or anal fissures can occur due to the increased pressure on your intestines as your baby grows and you the blood volume increases. The amount is usually small. The best way to reduce blood in your stool is by reducing or limiting strainging on the toilet. It is always best to reach out to your health care provider and notify them of any bleeding.

Loose Stools at the End of Pregnancy and During Labor

The pressure from your baby's head will cause elmination as the baby passes through the vaginal canal. This is the body's way of colonizing your baby with their first bacteria and immune support. It is common for your health provider to descretly remove stool quickly and without notice.
