Heartburn during pregnancy facts

  • Heartburn is a condition in which acid backs up (refluxes) from the stomach into the esophagus and sometimes up to the throat, irritating the tissues.
  • Heartburn during pregnancy can be overwhelming. To some women it seems a constant problem.
  • Heartburn during pregnancy can be a symptom of gastroesophageal reflux disease (GERD, or acid reflux).
  • Heartburn during pregnancy feels the same as heartburn when you are not pregnant - a burning pain in the upper abdomen or chest area.
  • Heartburn during pregnancy is a common symptom due to high levels of estrogens and progesterones during pregnancy causing the lower esophageal sphincter (the muscle at the lower end of the esophagus that normally prevents acid from refluxing) to weaken. This weakness resolves after delivery. In addition the growing uterus can also put pressure on the stomach and push acid into the esophagus.
  • Heartburn during pregnancy can usually be managed with changes in diet, lifestyle, and habits.
  • If lifestyle changes do not resolve the heartburn during pregnancy, a doctor may recommend antacids, but these should be used only under a doctor's supervision. Antacids may reduce the absorption of iron in the diet, and magnesium-containing antacids could slow labor. Consult your doctor before taking any medications, even over-the-counter (OTC) medicines, while you are pregnant.
  • Because heartburn during pregnancy is thought to be caused by pregnancy hormones, heartburn will usually go away after delivery and no further treatment is needed.
