Xiao Li is 5 months pregnant. Recently, she always feels dizzy, fatigued, and short of breath. The obstetric examination was megaloblastic anemia. The doctor prescribed folic acid and vitamin B12. Why should I take these two drugs at the same time?
Megaloblastic anemia is anemia caused by the lack of vitamin B12 or (and) folic acid, which impairs the synthesis of cellular DNA, leads to the disorder of nuclear development, and results in unbalanced nuclear and cytoplasmic development of the three lineage cells of the bone marrow and ineffective hematopoiesis. .
Taking folic acid can quickly correct the abnormal phenomenon of megaloblastic anemia and improve anemia, but it cannot prevent nerve damage caused by vitamin B12 deficiency, such as symmetrical numbness of hands and feet, unsteady gait, spinal cord Degeneration, etc.; and if folic acid is still taken in large doses, vitamin B12 will be consumed due to strong hematopoiesis, which will further reduce the content of vitamin B12 in serum, which will lead to the development of nerve damage. Therefore, the combination of vitamin B12 supplementation with folic acid supplementation can improve neurological symptoms.
