title: Gastro-intestinal bleeding--a major cause of iron deficiency in the elderly.
abstract: Iron deficiency of 10 g/dl haemoglobin or less was found in 18 (3.5%) of 511 patients admitted in one year to the Middlesex Hospital Geriatric Unit. Three patients were frail and not investigated. Gastro-intestinal lesions were demonstrated in all remaining 15 patients and specific therapy was instituted in 10 cases. Surgery was performed for colonic cancer at a resectable stage (Dukes B) in two cases. Patients with iron deficiency require adequate gastro-enterological investigation.
