Heartburn & Acid Reflux
Heartburn affects up to 80% of pregnant women, particularly in the second and third trimesters. It occurs when stomach acid backs up into the esophagus.
Common Causes
- Progesterone relaxing the lower esophageal sphincter (the valve between stomach and esophagus)
- Growing uterus pushing stomach upward, reducing its capacity
- Slower digestion during pregnancy allowing more acid production
- Eating habits and food triggers
Remedies That May Help
Eat Smaller Meals
5-6 small meals instead of 3 large ones keeps the stomach from overfilling.
Stay Upright After Eating
Wait at least 2-3 hours after eating before lying down.
Elevate Your Head
Prop up the head of your bed 6 inches with blocks, or use extra pillows.
Avoid Trigger Foods
Common triggers: spicy foods, citrus, tomato, chocolate, fried foods, and carbonated drinks.
Antacids
Calcium-based antacids (Tums) are safe during pregnancy. Avoid antacids containing aluminum or sodium bicarbonate.
When to Call Your Doctor
- Heartburn so severe it prevents eating or sleeping
- Difficulty swallowing or pain when swallowing
- Vomiting blood or dark-colored vomit
- Unexplained weight loss alongside heartburn
Frequently Asked Questions
Does heartburn mean my baby will have lots of hair?
Surprisingly, a 2006 Johns Hopkins study did find a correlation! But heartburn is caused by hormones and anatomy, not baby's hair.
Is Pepcid (famotidine) safe during pregnancy?
Most doctors consider famotidine safe during pregnancy when antacids aren't sufficient. Always consult your provider before starting any medication.
Will heartburn go away after delivery?
For most women, yes — heartburn resolves within days to weeks after delivery as hormone levels normalize and the uterus shrinks.
