Heartburn is a burning feeling that starts in the stomach and seems to rise up to the throat. During pregnancy, changing hormone levels slow down your digestive system, weaken the stomach sphincter, and your uterus can crowd your stomach, pushing stomach acids upward.
When you experience heartburn, or acid reflux, the LES relaxes enough to allow stomach acid to rise up into the esophagus. This can cause pain and burning in the chest area. During pregnancy, hormone changes can allow the muscles in the esophagus, including the LES, to relax more frequently.
