Pregnant women are most likely to suffer from iron deficiency anemia, because after pregnancy, pregnant women's bodies begin to bear the blood supply of both men and women. In order to meet the growth of the fetus, the blood volume of pregnant women will gradually increase. However, in the process of increasing blood volume, the increase of plasma is often more than three times that of red blood cells, so blood is easily diluted, and pregnant women may have different degrees of anemia symptoms. This kind of anemia during pregnancy is common, and about 15% of pregnant women will have symptoms, which is also called "physiological anemia" or "anemia during pregnancy".

Corrective principle:

1, general principles iron deficiency and mild and moderate anemia: mainly take oral iron, improve diet and eat iron-rich foods. Severe anemia: oral or injection of iron, some close to delivery or affect the fetus, but also a small number of times to transfuse concentrated red blood cells. Extremely severe anemia: the first choice is to transfuse concentrated red blood cells until HB > 70g/L. After the symptoms are relieved, it can be changed to oral iron. After Hb returns to normal, oral iron should continue for 3-6 months, or 3 months after delivery.

2. The dietary iron absorption rate of pregnant women is15%, and the physiological requirement of pregnant women is three times higher than that of menstrual period, and with the increase of pregnancy progress, iron intake is 30mg/d in the middle and late pregnancy. Dietary guidance can increase iron intake and absorption. 95% of dietary iron is non-heme iron.

Foods containing heme iron are red meat and poultry. Foods that promote iron absorption include fruits, potatoes, green leafy vegetables, cauliflower, carrots, cabbage and other foods containing vitamin C. Some foods will inhibit iron absorption, such as milk and dairy products, cereal bran, cereals, high-gluten flour, beans, nuts, tea, coffee and cocoa.

For oral iron, I recommend you to take Sulifenesin ferrous succinate tablets and ferrous iron.
