What is a common symptom related to pregnancy that could indicate possible complications requiring further examination?

During pregnancy, a severe and persistent headache can be an important symptom that indicates possible complications, warranting further examination. While headaches can be a common discomfort due to hormonal changes and increased stress during pregnancy, when they become severe and persistent, they can raise concerns about conditions such as preeclampsia or intracranial issues. Monitoring for additional symptoms such as visual disturbances, swelling, or elevated blood pressure is critical in these cases.

In contrast, fatigue can be expected during pregnancy as the body undergoes various changes, and many women experience increased urinary frequency and occasional heartburn without indicating serious complications. These symptoms often arise from natural physiological adjustments within the body, such as increased blood volume and hormonal effects. However, severe and persistent headaches may signal underlying conditions that necessitate a healthcare provider's attention.
