Iron deficiency anemia in pregnancy

During pregnancy, blood volume increases, and the increase in plasma is relatively greater than the increase in red blood cells, so the blood is diluted and physiological anemia occurs. Only if the red blood cell count is below 3.5 million / cubic millimeter. Or if hemoglobin is below 10 g / 100 ml, anemia is diagnosed. The cause of anemia can be due to weak spleen and stomach, indigestion resulting in inadequate intake of iron, folic acid, vitamin B12 and other hematopoietic substances, or due to excessive menstruation or parasitic disease, or chronic blood loss in the digestive tract. Mild anemia has little effect on the fetus. However, severe anemia can delay fetal development and even cause premature or stillbirth. Severe anemia in pregnant women can cause anemia heart disease, and anemia also reduces the resistance of pregnant women, so other inflammation is prone to occur during pregnancy, during or after delivery. Therefore, anemia should be actively prevented and treated.
