Is it normal to have the runs during pregnancy?

Why This Happens

Digestive changes are a hallmark of pregnancy. Because the body is undergoing massive systemic shifts, the gastrointestinal tract often reacts in unpredictable ways. Here are a few common explanations:

• Hormonal Shifts: Progesterone is known to slow down digestion (often causing constipation), but for some, the hormonal fluctuate can cause irregular bowel movements or an increase in motility for certain individuals.
• Dietary Changes: Many people change their eating habits during pregnancy, increasing their intake of fruits, vegetables, and fiber to combat constipation, which can occasionally lead to looser stools.
• Prenatal Vitamins: Some prenatal supplements, particularly those with high doses of magnesium or certain forms of iron, may irritate the gut or act as a mild laxative for some people.
• Increased Sensitivity: Pregnancy can make the body more sensitive to certain foods or triggers that previously didn’t cause a reaction, potentially leading to digestive upset.

What It Might Mean in Your Situation

Whether this is a “normal” part of your pregnancy or a sign of something else often depends on the pattern and accompanying symptoms. Consider the following factors to understand your specific situation:

Timing and Consistency: If the loose stools started immediately after changing your prenatal vitamin brand or starting a new diet, it is likely a reaction to those changes. If it is a consistent, mild change that doesn’t interfere with your day, it may simply be your body’s new baseline.

Accompanying Symptoms: There is a difference between simple loose stools and a gastrointestinal illness. If the runs are accompanied by a fever, severe abdominal cramping, nausea, or vomiting, it may indicate a viral or bacterial infection rather than a pregnancy-related hormonal shift.

Hydration Levels: The primary concern with frequent loose stools during pregnancy is dehydration. If you are feeling excessively thirsty, experiencing dark urine, or feeling dizzy, the situation becomes more urgent regardless of the cause.

What To Do About It

1. Track Your Triggers: Keep a simple food and symptom diary for a few days. Note what you ate and when the runs occurred. This helps you identify if a specific food (like a new fruit or a dairy product) is the culprit.
2. Adjust Your Intake Carefully: Focus on “binding” foods like bananas, rice, applesauce, and toast (the BRAT diet) to help firm up stools. Ensure you are sipping water or electrolyte drinks throughout the day to maintain hydration.
3. Communicate with Your Provider: At your next check-up, or via a patient portal, mention the change in your bowel habits. You might say, “I’ve noticed my stools have been much looser lately; could this be related to my vitamins or something I’m eating?”

Real-Life Example

Sarah, who is 14 weeks pregnant, noticed that she was experiencing loose stools three or four times a week. She wasn’t feeling sick, but she was worried. After tracking her meals, she realized she had significantly increased her intake of raw spinach and plums to be “healthier.” After moderating the amount of high-fiber raw produce and mentioning it to her midwife, she found a balance that stabilized her digestion while still getting the nutrients she needed.

When To Seek Outside Help

Because this topic involves physical health during pregnancy, you should always consult a licensed medical professional for diagnosis and treatment. Seek immediate medical attention if you experience high fever, blood in the stool, severe abdominal pain, inability to keep liquids down, or signs of severe dehydration. Outside help from a doctor or midwife is essential to ensure both the parent and baby remain healthy and hydrated.
