Medical News Today: What causes gas pain during pregnancy?

Women often have excess gas during pregnancy in addition to morning sickness and fatigue. Gas can cause uncomfortable bloating, cramps, and abdominal pain.

This article discusses the causes of gas in the different phases of pregnancy. We also cover treatments and home remedies for gas, and how to tell when abdominal pain is a cause for concern.


A person’s body goes through many changes throughout pregnancy. These include physical and hormonal changes that can cause excess gas.

Gas pain can range from mild discomfort to severe pain throughout the abdomen, back, and chest. A person may also notice bloating and stomach or intestinal cramps.

Early pregnancy

The hormones progesterone and estrogen increase significantly during the first trimester of pregnancy.

During the first trimester of pregnancy, the body undergoes drastic hormonal changes.

The hormones progesterone and estrogen increase significantly to thicken the uterine lining to prepare for the growing fetus. They work as follows:

  • Progesterone relaxes the muscles in the body, including those of the intestines. As the intestines relax, the digestive system slows down significantly.
  • Raised levels of estrogen can cause the body to preserve water and gas. This can cause discomfort and pain in the abdomen.

Late pregnancy

During the second and third trimesters, symptoms such as morning sickness and fatigue fade, and the uterus shifts its position to accommodate the growing fetus.

As the uterus expands, it puts pressure on the surrounding organs, causing digestive issues, such as constipation and excess gas. This can cause uncomfortable bloating and gas.

How to relieve gas pain in pregnancy

Although the changes brought on by pregnancy can cause uncomfortable symptoms, these changes are necessary for the growing fetus.

Lifestyle changes can help reduce excess gas and lessen some of the more uncomfortable symptoms that accompany excess gas.

Certain dietary habits can make gas worse during pregnancy.

In the later stages of their pregnancies, women may want to consider eating several small meals throughout the day. Drinking water can also help improve digestion and prevent muscle cramps.

Certain foods are known to cause excess gas. These can include, including:

  • fried foods
  • beans
  • coniferous vegetables
  • dairy products, such as like milk and yogurt
  • whole grains
  • fructose and sorbitol, (an artificial sweetener)
  • carbonated drinks, such as like soda or sparkling water

Women may relieve their gas pain and bloating by avoiding these foods and drinks. Everyone responds to foods differently, so keeping a food journal is a good way of figuring out exactly which foods cause digestive issues.

What else could cause abdominal pain in pregnancy

Constipation and bloating are common symptoms during pregnancy.

Excess gas can cause a sharp, stabbing pain in the abdomen, back, and chest. However, abdominal pain is a common symptom of other medical conditions.

Irritable bowel syndrome

Women who already have IBS may notice their symptoms worsening during their pregnancy. Hormonal changes and stress can greatly impact IBS symptoms.

Braxton-Hicks contractions

Also known as “practice” or “false” contractions, Braxton-Hicks contractions usually occur during the third trimester.

Unlike labor contractions that gradually last longer and become more painful, Braxton Hicks contractions are irregular and typically last up to 2 minutes.

Round ligament pain

A network of thick ligaments provides support for the uterus. As the uterus expands, it stretches these ligaments, especially the round ligament. This stretching can lead to a sharp pain in the lower abdomen or groin.

HELLP syndrome

HELLP is an acronym that describes the main symptoms of the condition, namely, hemolysis, elevated liver enzymes, and low platelet count.

HELLP is a potentially life-threatening condition that doctors closely relate to another serious condition they call preeclampsia.
