Intro
Heartburn is a common complaint during the third trimester of pregnancy, affecting up to 70% of women. This uncomfortable burning sensation in the chest and throat is caused by stomach acid flowing back up into the esophagus, a condition known as acid reflux. As the pregnancy progresses, the growing uterus puts pressure on the stomach, causing the stomach acid to flow back up into the esophagus, resulting in heartburn.
The third trimester is a critical period for fetal development, and the mother's body undergoes significant changes to accommodate the growing baby. One of these changes is the relaxation of the lower esophageal sphincter, which is the muscle that separates the esophagus and stomach. This relaxation allows stomach acid to flow back up into the esophagus, causing heartburn. Additionally, the increased pressure on the stomach from the growing uterus can also cause stomach acid to flow back up into the esophagus, exacerbating heartburn symptoms.
Heartburn during the third trimester can be uncomfortable and disrupt daily activities, but there are ways to manage and alleviate symptoms. Understanding the causes and symptoms of heartburn, as well as the available treatment options, can help women navigate this challenging period and find relief. In the following sections, we will delve into the world of heartburn during the third trimester, exploring its causes, symptoms, treatment options, and prevention strategies.
Causes of Heartburn During the Third Trimester

The causes of heartburn during the third trimester are multifaceted and can be attributed to several factors. One of the primary causes is the relaxation of the lower esophageal sphincter, which allows stomach acid to flow back up into the esophagus. This relaxation is caused by the increased levels of progesterone, a hormone that helps to relax muscles during pregnancy. Additionally, the growing uterus puts pressure on the stomach, causing stomach acid to flow back up into the esophagus, resulting in heartburn.
Other factors that can contribute to heartburn during the third trimester include:
- Eating large or heavy meals, which can put pressure on the stomach and cause stomach acid to flow back up into the esophagus
- Lying down after eating, which can cause stomach acid to flow back up into the esophagus
- Consuming trigger foods, such as citrus fruits, tomatoes, and chocolate, which can relax the lower esophageal sphincter and allow stomach acid to flow back up into the esophagus
- Drinking carbonated beverages, which can cause the stomach to expand and put pressure on the esophagus
