Symptoms

Fatigue and weakness
Pale skin
Shortness of breath
Dizziness or lightheadedness
Cold hands and feet
Brittle nails
Unusual cravings (pica)
Poor appetite
Headaches
Restless legs syndrome

Treatment Options

Oral iron supplements (ferrous sulfate)
Vitamin C with iron
IV iron supplementation
Blood transfusion (severe cases)
Dietary modifications
Treat underlying cause (GI bleeding, menorrhagia)
Erythropoiesis-stimulating agents (if CKD)
Folic acid supplementation

Risk Factors

1Menstrual blood loss
2Pregnancy
3Gastrointestinal bleeding
4Inadequate dietary iron
5Malabsorption disorders
6Chronic kidney disease
7Cancer
8Frequent blood donation
9Vegetarian/vegan diet without planning
10Infants and young children

Diagnostic Methods

  • 1Complete blood count (CBC)
  • 2Serum ferritin
  • 3Serum iron
  • 4Total iron-binding capacity (TIBC)
  • 5Transferrin saturation
  • 6Reticulocyte count
  • 7Stool occult blood test
  • 8Endoscopy/colonoscopy (if GI bleeding suspected)

Prognosis

Excellent with proper treatment and addressing underlying cause. Hemoglobin rises within 2-4 weeks, full correction in 2-3 months. Iron stores replenish in 3-6 months. Recurrence common if cause not addressed. Regular monitoring needed.

Prevention

  • Iron-rich diet (red meat, beans, spinach)
  • Vitamin C with iron meals
  • Iron supplementation (pregnancy)
  • Screening high-risk groups
  • Treat menorrhagia
  • Regular health check-ups
  • Proper infant nutrition

Research Status

Oral iron supplements first-line. IV iron for malabsorption or intolerance. Blood transfusion for severe cases. Treat underlying cause essential. Ferric maltol and newer formulations improving tolerance. Screening in pregnancy and high-risk groups recommended.
