Iron deficiency anemia (IDA) is the most common nutritional deficiency globally. This review covers IDA

Area of Science:

  • Hematology
  • Nutritional Science
  • Internal Medicine

Background:

  • Iron deficiency anemia (IDA) is the most prevalent nutritional deficiency worldwide.
  • IDA arises when bodily iron demands exceed absorption, leading to diverse health issues.
  • It significantly impacts adults, causing impaired physical capacity, immune dysfunction, and cognitive deficits.

Purpose of the Study:

  • To review the prevalence and diverse etiologies of IDA, particularly with confounding medical conditions.
  • To differentiate IDA from anemia of chronic disease using hematologic markers.
  • To outline current diagnostic strategies and discuss treatment options for IDA.

Main Methods:

  • Literature review focusing on IDA prevalence, causes, diagnosis, and treatment.

Related Experiment Videos

  • Analysis of hematologic measures for distinguishing IDA from anemia of chronic disease.
  • Synthesis of clinical presentation, biochemical tests, and differential diagnosis approaches.

    • Main Results:

    • IDA has multifaceted etiologies, including inadequate intake, impaired absorption, and chronic blood loss.
    • IDA exacerbates conditions like chronic kidney disease and congestive heart failure.
    • Distinguishing IDA from anemia of chronic disease requires careful evaluation of hematologic and clinical data.

    Conclusions:

    • IDA is a widespread condition with significant health implications.
    • Accurate diagnosis involves integrating clinical, biochemical, and differential diagnostic methods.
    • Effective management and further research into IDA are crucial.
