Non-anaemic iron deficiency.

Area of Science:

• Internal Medicine
• Hematology

Background:

• Iron deficiency without anemia is a prevalent condition.
• Patients often exhibit unexplained, non-specific symptoms.
• Diagnosis typically involves low ferritin and transferrin saturation with normal hemoglobin.

Purpose of the Study:

• To summarize the diagnosis and management of iron deficiency without anemia.
• To review the limited evidence on iron supplementation in non-anemic individuals.
• To outline treatment strategies and follow-up protocols.

Main Methods:

• Review of current medical literature on iron deficiency without anemia.
• Analysis of diagnostic criteria and treatment guidelines.
• Evaluation of oral and intravenous iron supplementation efficacy.

Main Results:

• Iron deficiency without anemia is characterized by specific iron study findings.
• Oral iron supplements are the primary treatment, with follow-up iron studies recommended.
• Intravenous iron may benefit non-responders, while intramuscular iron is not indicated.

Conclusions:

• Prompt identification and management of iron deficiency without anemia are crucial.
• Treatment strategies should be individualized based on patient response.
• Further research is needed to clarify the benefits of iron supplementation in this population.
