Heartburn In Pregnancy – Helpful Tips
Heartburn in pregnancy is caused by a muscular weakness. The muscle involved is the lower esophageal sphincter (LES), a ring of muscle between your stomach and esophagus. The LES is designed to relax when you swallow food so that the food can enter the stomach. Once the food is in the stomach, the LES is to tighten, keeping food and stomach acids from flowing back into your esophagus. If the LES always worked properly, no one would ever suffer heartburn in pregnancy.
Like many other parts of the body, however, the LES is affected by pregnancy. Heartburn in pregnancy is a frequent complaint.
