Iron-Deficiency Anemia - Its Causes, Diagnosis, and Treatment

Clinical Features:

Most of the patients will present with fatigue, tiredness, and dizziness. If anemia is severe, then breathlessness (dyspnea) is also present. Patient's working capacity is restricted, and palpitation can be present. If iron-deficiency anemia is present from early life (from six months to two years), then mental sluggishness and low IQ like neurological manifestations can be permanent. Iron is required for neurotransmitter synthesis and myelination. Hence, neurological features can be seen. Pica is sometimes associated with iron-deficiency anemia (IDA). If not treated, then IDA can cause heart failure or ischemic heart disease.


  1. Less nutritional intake, like protein energy malnutrition, poor quality food, etc.
  2. Blood loss, like in vaginal bleeding, parasitic infection, gastric ulcer, etc.
  3. Increased demand, like in pregnancy, adolescent, hyperthyroid patient.



  1. Find the cause of iron deficiency first and treat it. If a parasitic infection is the cause, then an antihelminthic drug like Albendazole is needed. And if IDA is caused by a peptic ulcer, then Pantoprazole should be used. For nutritional anemia, good food with more green leafy vegetables, jaggery, meat, etc. are beneficial.
  2. Ferrous sulfate is available in syrup and tablet form. This medicine can make the stool black in color, so no need to worry.
  3. For severe anemia (hemoglobin less than 7 g/dL) and for those who cannot take medicines orally, injectable iron is given, for example, iron sucrose.
