my wife ishaving haemoblin 45% , want to increase .
Explained in details.
I have gone through your question and history. I can understand your concern.
According to your history she has excessive bleeding in menstrual period due to fibroids.
So here main cause of low hemoglobin is blood loss. And main treatment is surgery to remove fibroid.
However she can take drugs like ferrous sulphate or ferrous fumarate to improve hemoglobin. Basically it is iron supplements to increase hemoglobin.
Consult your doctor and take treatment accordingly.
Thanks for using health care magic.
Wish you a very good health.
