Is burping more common during pregnancy?

Reviewed by Yoshinori Abe, MD

Internal Medicine

Yes, frequent burping is common during pregnancy. Hormonal changes—particularly rising progesterone—relax the digestive muscles, slowing digestion and causing gas to build up. As the uterus expands, it also presses on the stomach, pushing air upward and leading to more burping, bloating, and occasional heartburn.

While excessive burping during pregnancy is usually harmless, it can sometimes overlap with symptoms of acid reflux, gallbladder issues, or other digestive conditions worth ruling out. Because pregnancy affects every body differently, understanding what's normal versus what needs attention matters for both your comfort and your baby's health. Taking a few minutes to complete a free, instant, online symptom check can help you clarify what may be causing your symptoms and guide your next steps—whether that's a simple diet adjustment or a conversation with your provider.

Explanation

During pregnancy, many women experience changes in their digestion, which can lead to symptoms like burping. One reason for this is that pregnancy hormones can relax muscles, including those in the digestive tract. This relaxation can slow down digestion and cause gas to build up, leading to more burping.

Additionally, as the baby grows, there is more pressure on the stomach, which can push gas up and cause belching. Some women also experience heartburn during pregnancy, and belching can be a symptom of this.

In summary, it is not unusual for pregnant women to burp more than usual. However, if you are concerned or it is causing discomfort, you can use a free symptom checker to better understand your symptoms or talk to a healthcare provider.
