Thalassemia is thalassemia, and pregnant women with thalassemia are not excluded from having iron deficiency anemia. Thalassemia is a hereditary hemolytic disease caused by a disorder in the production of beads, which does not lead to iron deficiency per se. However, some patients, especially pregnant women, may suffer from thalassemia in combination with iron-deficiency anemia. Because pregnant women need to meet the nutritional needs of themselves and their fetus at the same time, their need for iron has increased, and if they do not consume enough iron, it may lead to iron deficiency anemia. Iron deficiency anemia is caused by an imbalance between the body’s demand for iron and its supply, resulting in the depletion of iron stored in the body, leading to a lack of iron in the red blood cells and resulting in anemia, which can be manifested by dizziness, headache, fatigue, tiredness, blurred vision, ringing in the ears, and the skin and mucous membranes are pale, bleeding and other symptoms. Pregnant women with thalassemia who suspect that they have symptoms of iron deficiency anemia should consult a doctor in a timely manner and receive treatment under the doctor’s guidance to ensure the healthy development of the fetus.
