What is a common cause of heartburn in pregnant women during the second trimester?

1. Increased stomach acid production

2. Pressure from the growing uterus

3. Sensitivity to baby movement

4. Dietary restrictions

The correct answer is: Pressure from the growing uterus

Heartburn during the second trimester of pregnancy is often attributed to pressure from the growing uterus. As the uterus expands, it can push against the stomach, which leads to a higher likelihood of stomach contents, including acid, moving back up into the esophagus. This physiological change, compounded by hormonal fluctuations that relax the lower esophageal sphincter, makes it easier for acid reflux to occur, resulting in the sensation of heartburn. While other factors such as increased stomach acid production might contribute in specific cases, the primary reason for the heightened incidence of heartburn during this stage of pregnancy is the mechanical pressure exerted by the expanding uterus. Understanding this can help in developing strategies for alleviating discomfort, such as eating smaller meals, avoiding certain positions, and remaining upright after eating.
