What is the cause of anemia in pregnant women?

　　Why do pregnant women anemia ? Women of childbearing age only store 2-3 grams due to menstrual blood loss and low total iron content in the body. For burden in the second half of pregnancy fetus During growth and childbirth, iron requirements increase. If non-pregnant women need 1 mg of iron per day, the daily iron requirement can increase to more than 4 mg in the second half of pregnancy. It is known that only 10% of the iron contained in food can be absorbed by the digestive tract. Pregnant women can only absorb 1-3 mg of iron from food every day, so there is always a distance from the actual requirement. Since the developing fetus still needs to absorb iron, pregnant women are prone to iron deficiency anemia, especially in multiple pregnancies and those with gastrointestinal chronic diseases. disease When normal iron absorption is affected, anemia will appear earlier and be more severe.

　　Dangers of anemia in pregnant women . Pregnant women with severe anemia may suffer from fetal hypoxia due to insufficient hemoglobin carrying oxygen, causing fetal intrauterine growth retardation and premature birth , or even stillbirth. Pregnant women themselves are also prone to gestational hypertension Syndrome, intrapartum and Postpartum Although there is not much bleeding, shock can occur due to insufficient blood reserves, or myocardial damage can occur due to severe anemia.

　　Therefore, pregnant women should check their hemoglobin regularly, and if anemia is found, they should be treated as soon as possible. In the second half of pregnancy, take 0.3 grams of ferrous sulfate (containing 60 mg of iron ions) every day. If 1/10 is absorbed, 6 mg of iron ions can be absorbed every day. This can increase iron reserves to prevent anemia. It is best to continue taking it until the end of lactation. 》》》 Six types of pregnant women who should not drink milk
