Iron deficiency; non-hematological manifestations.

Area of Science:

• Nutritional Science
• Human Physiology
• Medical Research

Background:

• Iron deficiency anemia is easily recognized and treated.
• Non-hematological effects of iron deficiency are often overlooked.
• Extensive evidence links iron deficiency to systemic functional alterations.

Purpose of the Study:

• To highlight the significance of non-hematological manifestations of iron deficiency.
• To draw attention to key areas for basic scientists and healthcare professionals.

Main Methods:

• Review of accumulated evidence from human and animal studies.
• Synthesis of findings on systemic effects of iron deficiency.

Main Results:

• Iron deficiency impacts cellular function, growth, motor development, behavior, and cognition.
• Impaired immunocompetence, reduced physical work capacity, and metabolic stress are observed.
• Adverse fetal outcomes and premature labor in pregnant women are associated with iron deficiency.
• Gastrointestinal and other organ systems are negatively affected.

Conclusions:

• Non-hematological consequences of iron deficiency are widespread and significant.
• Further research and clinical attention are needed for these overlooked manifestations.
