Why do pregnant women feel tired?
Fatigue in early pregnancy is very normal. Many changes are occurring as the new pregnancy develops, and women experience this as fatigue and an increased need for sleep. Lower blood pressure level, lower blood sugar levels, hormonal changes due to the soporific effects of progesterone, metabolic changes, and the physiologic anemia of pregnancy all contribute to fatigue. Women should check with their health care provider to determine if an additional work up, prenatal vitamin changes, and/or supplemental iron would be beneficial.
