Ferrous sulfate is primarily used to treat which condition?

Ferrous sulfate is primarily used to treat anemia, specifically iron deficiency anemia. Anemia occurs when there is a deficiency of red blood cells or hemoglobin in the blood, often due to a lack of iron. Ferrous sulfate is an iron supplement that can help increase the levels of iron in the body, thus aiding in the production of hemoglobin and improving the oxygen-carrying capacity of the blood.

This treatment is critical for individuals who have low iron levels due to various reasons, such as poor dietary intake, blood loss, or increased needs during pregnancy. By restoring iron levels, ferrous sulfate can effectively alleviate the symptoms associated with anemia, such as fatigue and weakness. Therefore, its primary use is directly linked to addressing iron deficiency and improving overall blood health.
