Low hemoglobin and normal ferritin during pregnancy suggests anemia, which may be megaloblastic anemia, aplastic anemia, etc. and should be treated promptly.
1. Megaloblastic anemia: often caused by vitamin B12 or folic acid deficiency. We should change the bad dietary habits and eat more fresh vegetables, fruits and other foods. Supplement folic acid and vitamin B12 in time.
2. Aplastic anemia: it is a group of diseases mainly manifested by the decrease in the number of bone marrow hematopoietic stem cells and qualitative defects leading to hematopoietic disorders, causing the decrease of peripheral whole blood cells (red blood cells, white blood cells, platelets).
Patients with remission should use contraception until the disease is in remission. If they are pregnant, they should be prepared for blood transfusion and abortion in the early stage of pregnancy, and in the middle and late stage of pregnancy, they should strengthen the supportive treatment, and under close supervision until full-term delivery.
If the hemoglobin is low during pregnancy, the patient should be admitted to the hospital in time to clarify the type of anemia, and treatment should be carried out under the guidance of the doctor.
