Iron Deficiency and Iron Deficiency Anemia: Potential Risk Factors in Bone Loss

Area of Science:

• Biochemistry
• Mineral Metabolism
• Bone Biology

Background:

• Iron is vital for numerous physiological processes, including oxygen transport and cellular functions.
• Iron deficiency is a widespread public health concern with significant systemic implications.
• Proper iron levels are essential for maintaining bone homeostasis and the function of bone cells.

Purpose of the Study:

• To review current knowledge on iron metabolism in deficiency states.
• To discuss the diagnosis and prevention of iron deficiency and iron deficiency anemia (IDA).
• To analyze the relationship between iron deficiency and bone loss, including underlying mechanisms.

Main Methods:

• Literature review of clinical observations and animal studies.
• Analysis of research on iron metabolism and its impact on bone health.
• Synthesis of information on diagnostic and preventive strategies for iron deficiency.

Main Results:

• Iron deficiency, with or without anemia, is linked to osteopenia and osteoporosis.
• Decreased intracellular iron disrupts osteoblast and osteoclast activity, causing bone loss.
• Studies highlight the critical role of iron in collagen synthesis and vitamin D metabolism.

Conclusions:

• Iron deficiency poses a significant risk to bone health, contributing to bone loss.
• Effective diagnosis and prevention of iron deficiency are essential for mitigating bone complications.
• Strategies for iron repletion and prevention can improve bone health and overall quality of life.
