Is ferrous sulfate effective in treating anemia?

Ferrous sulfate is effective in the treatment of iron-deficiency anemia, helping to increase iron levels in the body and promote hemoglobin synthesis. It is less effective for other non-iron deficiency anemia.
Ferrous sulfate is more effective in the treatment of iron deficiency anemia caused by malnutrition, pregnancy, and chronic blood loss. Iron is an important constituent of hemoglobin in red blood cells, and ferrous sulfate can replenish iron, thus promoting red blood cells to use iron to synthesize hemoglobin, increasing the concentration of hemoglobin and correcting iron deficiency anemia.
Taking ferrous sulfate may produce nausea, vomiting, abdominal pain, black stool and other gastrointestinal discomforts. This drug is contraindicated for people with severe hepatic and renal impairment and non-iron deficiency anemia, when anemia is detected, it is necessary to consult a doctor in a timely manner, and actively diagnose and treat the anemia under the guidance of the doctor. The use of ferrous sulfate should be in accordance with medical advice.
