From the Guidelines
The treatment approach for anemia presenting with nail findings should prioritize identifying and addressing the underlying cause, with iron deficiency anemia being the most common type associated with nail changes, and oral iron supplementation as the first-line treatment, as recommended by the British Society of Gastroenterology guidelines for the management of iron deficiency anaemia in adults 1.
Key Considerations
- Iron deficiency anemia is the most common cause of anemia associated with nail changes like koilonychia (spoon-shaped nails) 1.
- Oral iron supplementation is the first-line treatment for iron deficiency anemia, typically with ferrous sulfate 325 mg (containing 65 mg elemental iron) taken 1-3 times daily between meals with vitamin C to enhance absorption.
- Treatment should continue for 3-6 months after hemoglobin normalizes to replenish iron stores.
- For those who cannot tolerate oral iron due to gastrointestinal side effects, options include trying a different iron formulation or switching to intravenous iron preparations like iron sucrose or ferric carboxymaltose for severe cases.
Underlying Cause Identification
- The underlying cause of iron deficiency must be identified and addressed, whether it's blood loss, malabsorption, or dietary insufficiency 1.
- Approximately a third of men and postmenopausal women presenting with IDA have an underlying pathological abnormality, most commonly in the GI tract 1.
Other Types of Anemia
- For other types of anemia with nail findings, such as vitamin B12 deficiency, treatment involves B12 supplementation, typically 1000 mcg daily orally or intramuscularly for severe cases.
- Nail changes typically improve gradually as the anemia resolves, though complete nail remodeling may take several months due to the slow growth rate of nails.
Recent Guidelines
- The British Society of Gastroenterology guidelines for the management of iron deficiency anaemia in adults provide the most recent and highest quality evidence for the treatment approach 1.
- These guidelines emphasize the importance of identifying and addressing the underlying cause of iron deficiency anemia, as well as the use of oral iron supplementation as the first-line treatment.

From the Research
Nail Findings in Anemia
- Nail findings can be associated with anemia, particularly iron deficiency anemia 2
- Iron deficiency anemia can cause nail changes such as brittle nails, nail ridging, and koilonychia (spoon-shaped nails)
Treatment Approach
- The treatment approach for anemia presenting with nail findings depends on the underlying cause of the anemia 3
- Iron replacement therapy is often used to treat iron deficiency anemia, which can help improve nail health 2, 4
- Oral iron supplements are commonly used, but intravenous iron may be necessary in some cases 2, 4
Diagnostic Tests
- Diagnostic tests such as complete blood count, red cell indices, and reticulocyte count can help determine the cause of anemia 5
- Serum ferritin levels can be used to diagnose iron deficiency anemia 2
Management of Iron Deficiency
- The management of iron deficiency involves oral or intravenous iron replacement therapy, depending on the severity of the deficiency and the patient's response to treatment 4
- Evidence-based recommendations for the management of iron deficiency have been developed by expert panels, taking into account the latest research and clinical guidelines 4
