What are common discomforts during pregnancy?

During pregnancy, women frequently experience a variety of physical and emotional changes, leading to discomforts that are commonly reported. The correct choice identifies nausea, heartburn, back pain, and fatigue as typical discomforts.

Nausea, often referred to as morning sickness, commonly occurs in the first trimester due to hormonal changes. Heartburn results from the growing uterus pressing against the stomach and the associated hormonal changes that relax the esophagus' lower sphincter, allowing stomach acid to escape. Back pain is prevalent due to the additional weight and changes in posture as the pregnancy progresses, putting strain on the back muscles and spine. Fatigue is another common issue, often linked to hormonal fluctuations, the body working harder to support the developing fetus, and disrupted sleep patterns.

In contrast, the other options describe symptoms that are either less common or may indicate more serious health issues if experienced during pregnancy.
