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.
