Iron deficiency is a common issue among patients presenting to general practice. Management requires oral or intravenous iron replacement coupled with clinical assessment and consideration of further investigations to exclude serious causes.
Iron deficiency anaemia is the most common nutritional deficiency worldwide. Although it can be diagnosed simply through blood tests, the aetiology is diverse, and management can be nuanced. The causes range from inadequate dietary intake through malabsorption to bleeding, ulceration and malignancy of the gastrointestinal or genitourinary tracts. Prompt recognition and investigation of iron deficiency, especially in men and postmenopausal women, can lead to improved outcomes.
