If anemia is found before pregnancy, you can take oral medications such as ferrous sulfate tablets, multivitamin iron oral solution, blood generating granules, etc. to improve the symptoms of anemia before preparing for pregnancy. If the anemia is more serious and the effect of oral medication to correct the anemia is not good, you should actively find the cause of the anemia and correct the anemia with blood transfusion if necessary. You should eat more iron-rich foods such as animal liver, red dates, lean meat, etc., and actively correct the anemia so that the symptoms of anemia improve significantly before pregnancy.
