Anemia Across the Spectrum: A Holistic Review of Its Causes, Classification and Control Measures
Year: 2025
Type: article
Abstract: Background: Anaemia affects more than 1.6 billion individuals worldwide and remains a considerable public health issue, especially in low and middle-income nations. Anaemia, characterized by its diverse causes and clinical manifestations, necessitates a comprehensive diagnosis and therapeutic strategy. This study provides a thorough examination of the types and origins of anaemia, highlighting the importance of combining morphological and etiological categories for improved diagnosis and treatment. Methodology: A thorough literature review was performed utilizing PubMed, Scopus, and Embase, employing search phrases like “anemia,” “types of anemia,” “etiology of anemia,” “iron deficiency anemia,” “megaloblastic anemia,” and “sickle cell anemia.” Articles published in English from 2010 to 2024 were included. Results: The results categorize anaemia into seven principal types: iron deficiency, pernicious, hemolytic, sickle cell, thalassaemia, aplastic, and anaemia of chronic disease. Iron deficiency anaemia is the most extensively researched, although non-nutritional variants are inadequately represented, particularly in low-resource environments. Pernicious anaemia is common in elderly people with autoimmune disorders. Genetic disorders such as sickle cell anaemia and thalassemia profoundly impact areas like sub-Saharan Africa. The review examines the ramifications of hemolytic, aplastic, and inflammation-associated anaemia. Diagnostic instruments, such as complete blood counts, iron tests, and vitamin assays, are essential for precise classification and treatment. Conclusion: The review emphasizes the complex etiology of anaemia, highlighting the necessity of diagnostic instruments such complete blood counts and iron investigations for precise identification of underlying causes. Public health initiatives, such as iron supplementation, deworming, and maternity care, are recommended to alleviate the effects of anaemia. The analysis continues by advocating additional research into non-nutritional factors and region-specific strategies to successfully diminish worldwide anaemia prevalence. This comprehensive approach seeks to inform clinical practices and public health policy in tackling the multifaceted difficulties of anaemia.
