Iron Deficiency Assessment in the Setting of Daily Alcohol Use

Laboratory Interpretation

• Iron saturation of 5% is significantly below the diagnostic threshold of 16% that indicates iron deficiency, regardless of inflammation status 1, 2
• Low serum iron level of 11 further supports iron deficiency diagnosis 2

Impact of Alcohol on Iron Parameters

• Chronic alcohol consumption influences serum iron indices and liver iron content, which can complicate the interpretation of iron studies 3, 4
• Alcohol downregulates hepcidin transcription in the liver via oxidative stress, which can affect iron metabolism 4, 5

Clinical Implications

• Iron deficiency in alcohol users requires attention due to its impact on quality of life and functional status 1

Management Considerations

• Iron replacement therapy should be considered while addressing the underlying alcohol use 1
• Alcohol consumption should be reduced or eliminated as it can worsen iron metabolism disorders 3, 5
