Anemia - iron deficiency

The cause of the deficiency must be identified, particularly in older patients who are most susceptible to intestinal cancer.

Oral iron supplements are available (ferrous sulfate). The best absorption of iron is on an empty stomach, but many people are unable to tolerate this and may need to take it with food. Milk and antacids may interfere with absorption of iron and should not be taken at the same time as iron supplements. Vitamin C can increase absorption and is essential in the production of hemoglobin.

Supplemental iron is needed during pregnancy and lactation because normal dietary intake rarely supplies the required amount.

The hematocrit should return to normal after 2 months of iron therapy, but the iron should be continued for another 6 to 12 months to replenish the body's iron stores, which are contained mostly in the bone marrow.

Intravenous or intra-muscular iron is available for patients who can't tolerate oral forms.

Iron-rich foods include raisins, meats (liver is the highest source), fish, poultry, eggs (yolk), legumes (peas and beans), and whole grain bread.

With treatment, the outcome is likely to be good. In most cases the blood counts will return to normal in 2 months.

There are usually no complications. However, iron deficiency anemia may recur, so regular follow-up is encouraged. Children with this disorder may be more susceptible to infection.

Call for an appointment with the health care provider if symptoms suggestive of this disorder develop or if blood is noted in the stool.
