    Study Notes

    Microcytic Anemia Causes

    • Blood Loss: Chronic gastrointestinal bleeding and heavy menstrual cycles are the primary causes.
    • Iron Deficient Diet: Insufficient dietary iron intake is prevalent in infants, children, pregnant women, and vegetarians.
    • Poor Iron Absorption: Conditions like celiac disease and Crohn's disease hinder iron absorption.
    • Increased Iron Requirements: Growth spurts in children and the demands of pregnancy elevate iron needs.
    • Chronic Infection or Inflammation: Diseases such as diverticulitis and rheumatoid arthritis can contribute.

    Manifestations

    • Fatigue: Results from the decreased oxygen-carrying capacity of the blood.
    • Paleness: Caused by low hemoglobin concentration.
    • Shortness of Breath: Linked to reduced oxygen transport in blood.
    • Headache: Arises from insufficient oxygen.
    • Pica: An unusual craving for non-food items, indicative of nutritional deficiencies.
    • Brittle Nails: Iron deficiency affects nail growth and strength.
    • Spoon-Shaped Nails (Koilonychia): Altered nail shape due to lack of iron.
    • Hair Loss: Iron reduction can lead to decreased hair growth.
    • Angular Stomatitis: Cracks form at the corners of the mouth due to nutrient deficiencies.
    • Tachycardia: Increased heart rate as the body compensates for low oxygen levels.

    Diagnosis

    • Complete Blood Count (CBC): Shows low hemoglobin and hematocrit levels.
    • Serum Ferritin Levels: Low levels reflect depleted iron stores in the body.
    • Serum Iron Levels: Indicates iron deficiency when low.
    • Total Iron Binding Capacity (TIBC): High levels suggest iron deficiency in the blood.
    • Peripheral Blood Smear: May reveal microcytic hypochromic red blood cells.
    • Stool Guaiac Test: Used to detect gastrointestinal bleeding.
    • Endoscopy or Colonoscopy: Helps to identify GI bleeding sources.

    Treatment

    • Iron Supplementation: Oral forms are common; intravenous iron may be necessary for severe cases.
    • Dietary Changes: Encourage consumption of iron-rich foods like red meat, fish, beans, and greens.
    • Underlying Condition Management: Treat any identified causes like gastrointestinal bleeding or malabsorption.

    Other Causes of Microcytic Anemia

    • Anemia of Chronic Disease (ACD): Associated with chronic infections, inflammation, or malignancy.
    • Thalassemia: Genetic disorders impacting hemoglobin production.
    • Sideroblastic Anemia: Heme production is impaired due to an inherited issue.
    • Lead Poisoning: Lead disrupts heme synthesis.

    Microcytosis Causes (Not Necessarily Anemia)

    • Hereditary Spherocytosis: Inherited issues causing misshapen red blood cells.
    • Iron Deficient Diet: Similar to anemia, insufficient intake can lead to microcytosis.
    • Chronic Blood Loss and Malabsorption: Continual loss and inability to absorb nutrients.
    • Liver Disease & Hypothyroidism: Both can affect red blood cell morphology.
    • Chronic Renal Failure: Impacts red blood cell production and morphology.

    Diagnosis of Microcytosis

    • Complete Blood Count: Might indicate elevated red blood cell distribution width (RDW).
    • Peripheral Blood Smear: Can reveal the presence of microcytic red blood cells.
    • Further Investigations: Additional tests such as serum iron, ferritin, or liver function tests may be required based on the suspected cause.
