For minor iron deficiencies, a supplement can be taken or dietary changes can be made, according to the National Heart, Lung and Blood Institute. For more severe cases, surgery or blood transfusions may be needed.
Eating many iron-rich foods can help if a person's iron level is low. Red meat, dark leafy greens and tofu are all very high in iron. Vitamin C also helps the body absorb iron more efficiently. Iron supplements are also an option. A person should only take the recommended dosage as an overdose can cause serious harm. If the condition is severe or the person is not responding to diet changes or medication, a transfusion may be needed.
