Sleepiness in pregnant women at 6 months may be normal, but pathological causes such as anemia cannot be ruled out. As the levels of estrogen, progesterone and human chorionic gonadotropin gradually increase during pregnancy, and the metabolism of pregnant women speeds up at this time, the body’s calorie consumption is also accelerated, which may easily lead to insufficient blood glucose in pregnant women, thus leading to sleepiness. Pregnant women generally have no other discomfort, this situation is usually normal. If a pregnant woman fails to replenish the daily nutrients she needs during pregnancy, she may develop anemia, which may lead to 6-month sleepiness, often accompanied by dizziness and fatigue, which is usually abnormal. If a pregnant woman is sleepy in the 6th month of pregnancy, accompanied by the above mentioned symptoms, it is recommended to consult a doctor in time, under the guidance of the doctor, complete the relevant examinations, clarify the cause of the disease and treat the symptoms.
