Heartburn at night during pregnancy occurs due to the release of the hormone progesterone at increased levels. Progesterone relaxes the valve between the stomach and esophagus, which makes it easier for stomach acid to splash into the esophagus. If you are getting heartburn symptoms only at night, dietary and sleep routine changes may help alleviate symptoms.
Significance
Avoid eating a large meal in the evening if you tend to suffer from heartburn at night. Instead of having three large meals, consume four to six smaller meals over the course of the day. Large amounts of fluid also should be avoided in the evening hours. Allow at least two to three hours between your last meal and bedtime. This gives your body a chance to digest food before you lie down for bed.
Types
Certain foods you eat may trigger heartburn symptoms at night. Do not drink beverages that are carbonated or contain caffeine. Mint, chocolate, spicy foods and foods high in fat also can aggravate heartburn during pregnancy. Acidic foods may need to be limited. These include vinegar, citrus fruits, fruit juice and tomatoes. Steer clear of tobacco and alcohol, as well.
Prevention/Solution
The way that you sleep affects the severity of your heartburn symptoms. Avoid lying flat on your back during pregnancy. Instead use extra pillow to prop you up for sleep. Also, raise the head of the bed 4 to 6 inches to keep you elevated. An elevated sleep position prevents stomach acid from going into the esophagus. Wear loose and comfortable clothing for bed. Tight-fitting sleepwear can aggravate your heartburn symptoms.
Considerations
Chewable antacids typically are approved by your physician as a way to treat heartburn. The antacids neutralize acid and can be taken at bedtime when your symptoms appear. However, avoid antacids that contain aluminum, aspirin and sodium bicarbonate. Aluminum can be constipating to pregnant women, while sodium bicarbonate may cause you to retain water. Aspirin can reduce blood flow to the baby.
