Managing Loose Motions During Pregnancy’s Third Trimester

Pregnancy is a beautiful journey, but it comes with its fair share of discomforts, especially in the third trimester when your body is preparing for labor. One such common yet worrying issue is loose motions (diarrhea). Studies show that about 15-20% of pregnant women experience loose motions in the last trimester, often due to hormonal shifts, dietary changes, or an approaching labor sign.

While mild diarrhea is usually harmless, it can lead to dehydration and discomfort if not managed properly. This article will help you understand why loose motions occur in the third trimester, when to be concerned, and effective home remedies for relief.

Why Do Loose Motions Occur in the Third Trimester?

Several factors contribute to loose motions in the last weeks of pregnancy:

1. Hormonal Changes

As your body prepares for labor, it releases prostaglandins, which help soften the cervix and stimulate contractions. These hormones can also speed up digestion, leading to frequent, loose stools.

2. Changes in Diet

Many pregnant women focus on a healthier diet in the last trimester, increasing their intake of fiber-rich foods, fruits, and dairy. While beneficial, sudden dietary changes may cause an upset stomach.

3. Baby’s Growth and Uterus Pressure

As your baby grows, your uterus puts pressure on the intestines, which can alter digestion and cause either constipation or loose stools.

4. Prenatal Supplements

Certain prenatal vitamins, particularly those rich in magnesium, can act as mild laxatives and contribute to loose motions.

5. Infections or Food Sensitivities

Pregnancy can weaken immunity, making you more susceptible to infections from contaminated food or water. Additionally, some women develop temporary food sensitivities during pregnancy.

6. Sign of Early Labor?

For some women, loose motions 1-2 weeks before delivery could be a natural sign that the body is preparing for labor. However, if diarrhea is severe or accompanied by contractions, consult your doctor immediately.

When to Seek Medical Attention?

While occasional loose stools are normal, consult your doctor if you experience:
✅ Loose motions lasting more than 2 days
✅ Signs of dehydration (dark urine, dry mouth, dizziness)
✅ Fever, chills, or severe stomach cramps
✅ Blood or mucus in stools
✅ Strong contractions indicating preterm labor

Safe and Effective Home Remedies for Loose Motions in Pregnancy

1. Stay Hydrated

Loose motions can cause dehydration, which is risky during pregnancy. Drink:

• Coconut water (natural electrolytes)
• ORS solution (rehydration salts)
• Buttermilk with a pinch of rock salt (soothes the stomach)
• Jeera (cumin) water (boil cumin seeds in water and sip slowly)

2. Follow the BRAT Diet

The BRAT diet is easy on the stomach and helps firm up stools:
🍌 Bananas – Rich in potassium, replenishes lost nutrients.
🍚 Rice – A gentle, binding food.
🍏 Applesauce – Contains pectin, which helps firm stools.
🍞 Toast – Easy to digest and calming for the stomach.

3. Ginger Water or Herbal Tea

Ginger is known for its anti-inflammatory properties. Sip on ginger water or tea to soothe your stomach and regulate digestion.

4. Yogurt & Probiotic Foods

Probiotic-rich foods like curd, buttermilk, and fermented rice help restore good gut bacteria and improve digestion.

5. Boiled Potatoes or Moong Dal Khichdi

Plain boiled potatoes or moong dal khichdi with minimal spices are easy to digest and provide energy.

6. Avoid Triggers

🚫 Greasy, spicy, or fried foods
🚫 Excessive dairy (if you have lactose sensitivity)
🚫 Raw or uncooked food (may contain bacteria)
🚫 Caffeine and carbonated drinks

7. Rest and Relaxation

Stress and anxiety can make digestive issues worse. Try:
