Our hematologists stipulate that the hemoglobin concentration in adult women is 110-150 g/L, below 110 g/L is anemia, above 150 g/L is increased hemoglobin concentration, and also stipulate that hemoglobin concentration ≥ 100 g/L in pregnant women is normal. In China, the most common type of anemia in women is iron-deficiency anemia. The reason is that due to the existence of physiological conditions such as menstrual cycle, lactation, and pregnancy, women have a greater demand for iron, and if iron-rich foods are not added to the daily diet in a timely manner, it is very easy to cause iron-deficiency anemia. Therefore, in clinical practice, iron deficiency anemia is very common in pregnant women or women of childbearing age. After women suffer from iron deficiency anemia, they should pay attention to eating more iron-rich foods, such as animal liver, pig’s blood and sheep’s blood. Also do not drink tea in daily life because the tannic acid in tea can affect the absorption of iron. In case of severe iron deficiency anemia, iron supplementation therapy is also required.
