Anemia is a relatively common phenomenon in pregnant women during pregnancy. Due to the influence of some physiological factors during pregnancy, such as an average 50% increase in blood volume of pregnant women during pregnancy and vomiting in early pregnancy, the hemoglobin in the blood can be relatively reduced or insufficient, thus resulting in anemia. The severity of anemia symptoms is not necessarily proportional to the degree of anemia, and many symptoms are often related to the degree of occurrence of anemia, the urgency of its onset and the compensatory capacity of various organs of the body. In general, mild anemia symptoms are not obvious, although there will be pale skin and mucous membranes, which can be detected by routine blood tests. Symptoms of moderate anemia or above may include general weakness, easy fatigue, dry skin and hair, pale face, thin and brittle nails that break easily, poor concentration and memory loss. In severe cases, there may be difficulty in breathing, palpitations, chest pain, etc. If a pregnant woman is anemic during pregnancy, mild anemia can be treated by strengthening nutrition, improving diet and other dietary treatments, but if the anemia is moderate or above, medication should be administered under the guidance of a doctor. Normally, pregnant women should keep a good mood and exercise properly, which will also improve their immune system and can also play a role in preventing anemia.
