Which is a common physical symptom experienced during the second trimester of pregnancy?

During the second trimester of pregnancy, one common physical symptom that many women experience is heartburn. This can be attributed to a combination of hormonal changes and the physical changes occurring in the body as the pregnancy progresses.

During the second trimester, the growing uterus can press against the stomach, which may lead to the backup of stomach acid into the esophagus, resulting in heartburn. Additionally, hormonal influences, particularly the relaxation of the lower esophageal sphincter caused by progesterone, can contribute to this sensation.

While nausea and vomiting are most frequently associated with the first trimester, urinary frequency typically decreases during the second trimester as the uterus lifts away from the bladder. Fatigue can be present, but it generally stabilizes or improves as the pregnancy continues into the second trimester, as many women begin to adapt to their changing bodies. Therefore, heartburn stands out during this stage as a significant and common symptom.
