More than one-half of all pregnant women report symptoms of severe heartburn, particularly during their third trimester. Heartburn might occur during pregnancy because of changing hormone levels, which can affect how different foods are tolerated and how food is digested. Pregnancy hormones can also cause the lower esophageal sphincter (the muscular valve between the stomach and esophagus) to relax, allowing acids to splash back up into the esophagus. In addition, your enlarged uterus can crowd your stomach, pushing stomach acids upward.
Eat several small meals a day instead of three large ones.
Eat slowly.
Avoid fried, spicy or rich foods, or any foods that seem to increase your heartburn.
Don’t lie down immediately after eating.
Keep the head of your bed higher than the foot of your bed, or place pillows under your shoulders to help prevent stomach acids from rising into your chest.
Ask your doctor about trying over-the-counter heartburn relievers such as Tums or Maalox.
If your heartburn persists, see your doctor. He or she might prescribe medicines that are safe to take during pregnancy.
