Heartburn occurs when stomach acid backs up into the esophagus instead of staying in your stomach, causing a burning sensation in your chest or throat. While all people are at risk, pregnant women are more likely to experience heartburn, especially later in pregnancy.

What is the reason of this?

Your pregnancy hormone progesterone is back at work, relaxing all of your body's smooth muscle tissue, causing your esophagus to be unable to keep stomach acid from coming back. Progesterone also makes digestion slower, causing heartburn. This effect may increase later in pregnancy as your baby grows and fills your abdominal cavity.

Tips

Try to eat more healthy foods such as fresh fruits, vegetables, and lean meats and avoid fried or highly processed foods as they are more likely to cause heartburn. Chewing gum after eating and avoiding eating too close to bedtime are other ways to prevent heartburn. Caffeine, tobacco, and alcohol can also increase the effects of heartburn. You should let your healthcare provider know if your heartburn is not improving with dietary modifications.
