Heartburn is a burning feeling behind the breastbone. It may occur after eating, soon after lying down, or when bending forward. Heartburn may also occur after taking certain medicines.

Heartburn is a common symptom during pregnancy. As the uterus gets bigger during pregnancy, it puts more upward pressure on the stomach. About 25% of pregnant women have heartburn every day, and 50% of pregnant women have heartburn at least once a month.

If you have symptoms of heartburn, it is okay to use Tums. Be sure to talk with your doctor before taking any other heartburn medicines. Some medicines may not be safe to take during pregnancy.

If your heartburn is causing a problem and you cannot eat, drink, or do your usual activities during your pregnancy or after delivery, talk to your doctor about treating your heartburn.

After delivery, heartburn is likely to go away on its own. If you still have heartburn symptoms, you can try some nonprescription medicines for relief. Be sure to follow the instructions on the label. If you are breast-feeding, be sure to check with your doctor about what medicines you can use.
