    Study Notes

    Anemia Overview

    • The most common type of anemia is iron deficiency anemia.
    • Iron deficiency anemia primarily results from inadequate iron intake or absorption in the body.

    Iron Deficiency Anemia in Infants

    • Premature infants experience iron deficiency anemia due to lower iron stores at birth, as they miss the last trimester when significant iron accumulation occurs.
    • In full-term infants, iron stores are found primarily in the liver, spleen, and bone marrow.

    Iron Loss and Storage

    • The leading cause of iron loss in the body is chronic blood loss, often due to menstrual cycles or gastrointestinal bleeding.
    • The liver stores approximately 30% of the total iron in the body.
    • In adults, the normal range of serum iron levels is typically between 60 to 170 mcg/dL.

    Clinical Manifestations and Dietary Recommendations

    • A common clinical manifestation of anemia includes fatigue and weakness due to reduced oxygen transport.
    • To enhance iron absorption, increasing vitamin C-rich dietary sources such as citrus fruits and vegetables is recommended.

    Supplementation Guidelines

    • Iron supplementation for infants is commonly recommended to begin around 6 months of age to support growth and development.
    • Aplastic anemia is a condition characterized by the failure of the bone marrow to produce sufficient blood cells.

    Nutritional Deficiencies

    • Iron deficiency anemia represents the most prevalent and preventable nutritional disorder globally.
    • The most common anemia in children is also iron deficiency anemia.

    Iron Distribution in the Body

    • 65% of the total iron in the body is bound up in hemoglobin within red blood cells.

    Side Effects and Causes of Aplastic Anemia

    • A potential side effect of iron supplementation can include gastrointestinal upset, such as constipation and nausea.
    • The main cause of aplastic anemia involves damage to the bone marrow, which may be due to toxins, medications, or autoimmune diseases.
