      • Heme iron is more readily absorbed than nonheme iron.
        • Heme iron sources include: beef, chicken, turkey, oysters, egg yolk
        • Nonheme iron sources include: bran flakes, brown rice, leafy greens, oatmeal, dried fruits
      • Folic acid sources include: green leafy vegetables, broccoli, wheat germ, milk, yeast, kidney beans, eggs

      • Tea and coffee inhibit nonheme iron absorption.
    • Lifestyle management involves balancing activity with rest to optimize oxygenation and energy.
    • A healthy diet is essential to enhance energy levels, even if it cannot fully manage the condition.

    Rest and Activity

    • Rest and activity balance is crucial for people with anemia due to their impaired oxygenation.

    Nutrition

    • Proper nutrition is especially vital when dealing with deficiency anemias caused by a lack of iron, vitamin B12, or folic acid.

    Iron Sources

    • Heme iron, found in animal products, is more easily absorbed than nonheme iron, which is found in both animal and plant sources.
    • Heme iron enhances nonheme iron absorption when eaten together.
    • Good Heme Iron Sources: Beef, chicken, turkey, oysters, egg yolk, real, loin
    • Good Nonheme Iron Sources: Bran flakes, Brown rice, whole-grain breads, dried beans, leafy greens, oatmeal, dried fruits.

    Folic Acid Sources

    • Good Sources: Green leafy vegetables, broccoli, wheat germ, milk, yeast, kidney beans, eggs, organ meats, asparagus.

    Vitamin B12 Sources

    • Good Sources: Liver, milk, cheese, fresh shrimp and oysters, organ meats (muscle), eggs.

    Absorption Tips

    • Vitamin C improves the absorption of nonheme iron.
    • Tea and coffee decrease nonheme iron absorption.

    Lifestyle Management

    • Balancing activity with rest helps improve oxygenation and energy levels.
    • Maintain a nutritious diet even if it doesn't completely resolve the anemia. A healthy diet can still boost energy levels.

    Blood Transfusion Indications

    • Blood transfusions are used to treat significant blood loss, often due to trauma or surgery.
    • They are also used in cases of severe anemia, particularly when the individual is experiencing cardiovascular instability.

    Types of Blood Transfusions

    • Whole Blood: Replaces both red blood cells and blood volume, making it suitable for acute hemorrhage situations.
    • Packed Red Blood Cells: Primarily given to individuals with severe anemia who are experiencing complications related to their heart function.

    Special Cases

    • Aplastic Anemia: This condition necessitates blood transfusions as part of the overall treatment plan.
    • Thalassemia: Individuals with this genetic disorder often require lifelong blood transfusions to manage their condition.

    Neonatal Anemia Causes

    • Blood Loss (Hypovolemia)

      • Prenatal: Placental bleeding (e.g., placenta previa, abruptio placentae), cord malformations, diagnostic procedures like amniocentesis or chorionic villus sampling can cause blood loss.
      • Perinatal: Precipitous delivery resulting in umbilical cord bleeding, birth trauma to the cranium subgaleal bleed or damage to abdominal organs.
      • Postpartum: Hypoxia, shock, or death causing subgaleal bleed.

    • Decreased RBC Production

      • Congenital defects: Fanconi anemia, Diamond-Blackfan anemia (rare).
      • Acquired defects: Infections (rubella, syphilis, HIV, bacterial sepsis) impairing bone marrow.
      • Nutritional deficiency: Deficient in B12, folate, vitamin E, or iron (not common at birth).

    • Excessive RBC Hemolysis

      • Blood group incompatibilities or RBC disorders (G6PD deficiency (most common), hemoglobinopathies, infections).

    • Physiologic Anemia of the Newborn

      • Normal breathing after birth increases oxygenation, decreasing erythropoiesis (RBC production).
      • A combination of decreased erythropoiesis and the decreased lifespan of neonatal RBCs results in a drop in hemoglobin over the first 6–12 weeks.
      • Erythropoietin stimulation and bone marrow activity eventually stabilize hemoglobin levels.
