Patient's question:
NoDoctor's answer:
Iron deficiency is primarily seen in situations where the demand for iron increases while the supply remains relatively insufficient, such as during pregnancy, lactation in women, and in infants and children during periods of growth and development. It can also occur when iron absorption decreases, such as in individuals with low stomach acid or those who have undergone partial gastrectomy. Iron loss can be excessive, as two-thirds of the body's iron is present in hemoglobin, so blood loss is essentially iron loss. Chronic and repeated blood loss, such as from heavy menstrual bleeding, ulcer bleeding, hemorrhoidal bleeding, or hookworm infection, can deplete iron stores in the body, leading to iron-deficiency anemia. Blood tests may reveal a decrease in red blood cell count and hemoglobin levels, as well as smaller-than-normal red blood cells with pale staining (due to lower hemoglobin content in the red blood cells), reduced serum iron and serum ferritin levels, and decreased iron stores in the bone marrow.
