Causes Of Diarrhea In Pregnancy

Pregnancy brings several hormonal and other changes. Changes in hormones could also bring along certain variations in the gastrointestinal tract.

The following possible factors may lead to diarrhea in pregnancy (3).

  • Elevated levels of prostaglandinsiXA group of lipids with hormone-like actions that help induce labor in pregnant women. may lead to diarrhea (4). Some hormones may cause one’s digestive process to slow down, leading to diarrhea gradually (5).
  • Some women make drastic changes in their diet once they know they are pregnant. These sudden dietary changes may sensitize the gastrointestinal tract, causing diarrhea. This is seen more commonly in the first trimester of pregnancy.
  • Excess binge eating of junk food due to pregnancy-related cravings may cause diarrhea.
  • Many women are stressed regarding the baby’s well-being during pregnancy. Stress could be a predisposing factor for diarrhea in pregnancy.
  • Some women are advised bed rest in pregnancy for certain medical reasons. A sedentary lifestyle may lead to a weak digestive system, causing diarrhea eventually.

  • Some women may develop diarrhea due to prenatal vitamins. You may change the brand of the vitamins and see if it helps.
  • Heartburn, morning sickness (nausea and vomiting), and acidity are common in pregnancy, especially during the first trimester. Doctors may prescribe some antacids to help you. Magnesium in these antacids may cause diarrhea in some women (6).
  • Some food items may cause sensitivity in the GI tract. Even if these items were well-tolerated pre-pregnancy, they might cause an upset stomach during pregnancy.
  • If nausea and vomiting return after mid-pregnancy, it could be a sign of preeclampsia, which is estimated to occur in five to seven percent of all pregnancies, as per a CDC report.

Dairy products could also cause diarrhea during pregnancy if you are lactose intolerant (13).
  • Diarrhea may occur a week or two before the labor. However, if you experience diarrhea during the third trimester, it does not necessarily mean that labor is approaching. You should also check other signs of approaching labor before getting alarmed (5).

Becky, a mother to two, shares her experience of dealing with diarrhea during the last trimester of her pregnancy. Having already lost her mucus plug and being in the process of dilation, she wonders if this could be a sign of approaching labor. She says, “A couple of weeks ago, I started to have loose stools… Things loosened up for me these last few weeks. When it first happened, I thought, ‘Maybe this is a sign!’ Well, today, I’ve had a little diarrhea. Nothing too major, but enough to get me thinking (once again), ‘Maybe it’s time!’

“Anyway, I suppose it could just be a coincidence, but with the dilation and loss of mucus plug, I can’t help but think labor is going to start very, very soon (i).”

The following causes are not pregnancy-related but may still lead to diarrhea.

  • Food poisoning
  • Viral or bacterial infections
  • Intestinal parasites
  • Traveler’s diarrheaiXAn intestinal bacterial infection one may contract from eating contaminated food.
  • Crohn’s diseaseiXA chronic condition causing inflammation of the digestive tract.
  • Irritable bowel syndrome
  • Celiac diseaseiXAn autoimmune and genetic condition characterized by an immune reaction to gluten, the protein found in barley, rye, and wheat.
