Why Does Heartburn Occur During Pregnancy?
Heartburn is very common during pregnancy. Heartburn occurs when hormones cause the digestive system to slow down. Hormones also cause the muscles that push food down the esophagus to slow down during pregnancy. In addition, as the uterus grows, it pushes on the stomach and sometimes forces stomach acid up into the esophagus. Heartburn is common during pregnancy but it rarely causes complications. In rare instances, inflammation of the esophagus (esophagitis) or harm to the fetus can occur. Usually, GERD symptoms such as heartburn improve or disappear once the baby is born.
