Heartburn During Pregnancy: Causes, Symptoms, Prevention & Treatments

Heartburn during pregnancy

Heartburn and pregnancy often go hand-in-hand. Many women begin experiencing heartburn early in their pregnancy, and it often continues until the baby is born. For some women, pregnancy is the first time they experience this symptom1. Among women who have previously dealt with heartburn, pregnancy may make the condition worse1.

Make sure to tell your doctor about any new or changing heartburn symptoms. There may be simple solutions to help prevent or lessen this symptom.

What Causes Heartburn During Pregnancy?

Heartburn happens when stomach contents travel back up into the esophagus, the tube that leads from the mouth to the stomach. At the bottom of the esophagus, the lower esophageal sphincter (LES) muscle opens and closes to allow food into the stomach. The LES is typically closed when you are not swallowing. However, when this muscle is more relaxed, it may allow some of the undigested food and stomach acid to flow upward into the esophagus1.

Several different factors can trigger heartburn during pregnancy. One of the causes is hormones like progesterone, which your body produces at high levels while you are pregnant. Progesterone relaxes the LES, increasing the chances that stomach contents will leak into your esophagus2.

Progesterone also relaxes muscles in the digestive system, preventing the stomach from emptying as quickly. The longer your stomach remains full of food, the more likely you are to experience the symptoms of heartburn2.

Certain medications can also increase heartburn. If you take drugs to treat nausea or high blood pressure during pregnancy, you may experience heartburn as a side effect1,3.

Another cause of heartburn in pregnancy is the pregnancy itself. As the baby grows, the uterus puts more pressure on the stomach. This pressure can push the contents of the stomach upward and into your esophagus, causing you to experience heartburn4.

Symptoms can begin at any time during pregnancy, but they tend to be worse during the second and third trimesters. Some women who experience heartburn in pregnancy have never had this issue before. For women who have heartburn before becoming pregnancy, heartburn during pregnancy may be more severe5.

Symptoms Of Heartburn During Pregnancy

Heartburn is a burning feeling that may be felt between the middle of your chest under your breastbone, up into your throat6. It can also cause:

  • Burning pain in chest
  • Burning feeling in the throat
  • Sour and Acidic taste in the mouth or throat
  • Pain that worsens when lying down or bent over

How Can Heartburn Be Prevented?

It may be difficult to completely block all feelings of heartburn during pregnancy, but you can take several steps to reduce the frequency and severity of the symptoms you experience. First and foremost, talk to your primary care provider or obstetrician. Under their supervision, you may be able to try various remedies such as avoiding foods that trigger your heartburn.

Treatment of Heartburn During Pregnancy
