What is a common characteristic of pregnancy-related fatigue?

Pregnancy-related fatigue is predominantly associated with hormonal changes that occur during pregnancy. During this period, there is a significant increase in hormones such as progesterone, which can lead to feelings of tiredness and lethargy. Additionally, other hormonal shifts, along with the body's increased metabolic demands and adjustments in cardiovascular functioning, contribute to this common symptom.

While fatigue can be pronounced at various stages of pregnancy, it is not limited solely to the first trimester, as it can persist well into the second and third trimesters due to ongoing physical and emotional adjustments. The severity of fatigue can vary from person to person; it is not universally severe or debilitating, as many individuals may find their fatigue manageable. Furthermore, while dehydration can cause fatigue, it is not a direct cause of the fatigue associated with pregnancy itself, which is primarily attributed to hormonal fluctuations and the physiological changes of carrying a fetus.
