A 48-year-old member asked:

why is iron deficiency anemia a microcytic anemia?

Microcytic: Iron is needed in order for the body to produce hemoglobin (hb) -a substance in red blood cells (rbc) that enables them to carry oxygen.Without hb, RBC will not be able to transport blood to tissues. Microcytosis means the presence of rbcs with a MCV (volume of average rbc) less than normal--smaller rbc. In iron deficiency- there is decreased hb content within the rbc, so it is smaller /microcytic.

Decreased Hemoglobin: Red blood cells (rbcs) are essentially little bags carrying lots of hemoglobin (hb). Iron is an important constituent of the hb molecule. Low iron = low hemoglobin = less packing into rbc. Since the RBC is now filled less, a microcytic anemia results.

Do I need to give my baby an iron supplement?

Yes: If your baby is breast fed i recommend starting polyvisol with iron, 1 dropper per day, for the entire first year of life starting at 1 week. This covers the needs of vitamin d and iron for the breast fed baby. If your baby is formula fed on a fully iron-supplemented formula, additional iron is usually not required.

Yes: Kidney failure is often associated with anemia. The lack of erythropoietin, an essential hormone produced by the kidneys that enhances red cell production from bone marrow, would be the easiest explanation.

Does a lack of sleep lead to anemia?

Dr. Sherin Ibrahim Howett
Sleep Medicine 18 years experience
No: Both lack of sleep and anemia can lead to feeling tired and fatigued. Anemia is caused by either blood loss, cell destruction or insufficient production. In women, iron deficiency anemia and excessive bleeding during menstruation are the most common causes. Lack of folate (folic acid) and vitamin B12 also cause a different form of anemia. There are also genetic diseases that result in anemia.

If I am taking menopausal hormone therapy (mht) how does that affect the amount of iron I should take?

2 doctor answers5 doctors weighed in
Dr. Albert Pizzo
Family Medicine 60 years experience
Iron: Usually after menopause the persons need for iron drops drastically because the menstrual periods have stopped. Blood loss requires lots of iron to manufacture new red blood cells. After menopause it is advisable not to take iron as too much iron can cause illness in the body e.g. Iron buildup in the liver called hemochromatosis.
