Abstract
Iron deficiency is the most common
nutritional disorder worldwide, affecting approximately 1.2 billion people.
This issue represents a silent epidemic with profound multidimensional
consequences for health and socio-economic development, making a comprehensive
examination of its various aspects essential. This review study aims to
comprehensively analyze the different dimensions of iron deficiency, including
its pathophysiology, epidemiology, risk factors, clinical manifestations,
diagnostic challenges, and contemporary management strategies. A literature
search was conducted in scientific databases, including PubMed and Google
Scholar, for articles published between 2015 and 2024. The primary focus was on
systematic reviews, meta-analyses, and clinical guidelines to synthesize the
existing evidence. The findings indicate that Iron Deficiency Without Anemia
(IDWA) is a hidden stage of the disorder that is often overlooked, despite
being associated with significant complications such as cognitive impairment,
reduced productivity, diminished quality of life, and weakened immune function.
Diagnosing this condition is often challenging due to the non-specific nature
of symptoms and limitations of conventional laboratory tests. Furthermore,
gastrointestinal side effects of oral iron supplements and unequal access to
healthcare services complicate clinical management in many regions worldwide.
Effective management requires an integrated and multi-level approach. A
successful response to this silent epidemic depends on the implementation of
targeted screening in high-risk groups, evidence-based nutritional education,
large-scale food fortification programs, and the utilization of novel,
better-tolerated iron formulations. Such integrated interventions are crucial
for reducing the global prevalence of iron deficiency and improving health
indicators and the quality of life for individuals and communities.
