uses of Iron in the body

The drugs that increase the formation of RBCs (Hb)  are called haematinics. they are iron, folic acid, vitamin B12, ferrous sulfate.

Iron :

Iron present in the blood as a component of hemoglobin. It is an essential component of blood production. Iron is necessary for the normal growth of the body.

More iron is required to maintain hemoglobin due to higher physical demand during pregnancy, breastfeeding, or infancy.

The daily requirement of iron for an adult is 1 - 1.5 mg/day. Whereas iron requirements are more in women.

In the iron deficiency state, the amount of iron present in the body decreases, due to which the level of hemoglobin decreases. Which is gradually completed by taking extra iron. Iron content refills very slowly, even after hemoglobin is normal. Therefore, the normalization of HB oral iron therapy continues for a long time.
