It’s called heartburn, although that burning feeling in your chest has nothing to do with the heart. Uncomfortable and frustrating, it bothers many women, particularly during pregnancy.
The first question you may have is how to make it stop. You may also wonder if treatments are safe for your baby. Learn what causes heartburn during pregnancy and what you can do about it.
What causes heartburn during pregnancy?
During normal digestion, food travels down the esophagus (the tube between your mouth and stomach), through a muscular valve called the lower esophageal sphincter (LES), and into the stomach.
The LES is part of the doorway between your esophagus and your stomach. It opens to allow food through and closes to stop stomach acids from coming back up.
During pregnancy, hormone changes can allow the muscles in the esophagus, including the LES, to relax more frequently. The result is that more acids may seep back up, particularly when you’re lying down or after you’ve eaten a large meal.
