title: [Clinical reasoning and decision-marking in practice. A general practitioner with long-standing anaemia].
abstract: In order to calibrate his haemoglobin meter, a general practitioner had his own haemoglobin level checked regularly at a nearby laboratory. At 37 years of age, one of these assays revealed 7,0 mmol/l. Because he had no symptoms, he prescribed himself iron-substitution therapy but the haemoglobin concentration did not normalise. At 52 years of age, the patient increasingly suffered from fatigue and exertional dyspnoea and had intermittent abdominal pain, distension and rumbling. Biopsies of the small intestine revealed crypt hypertrophy and intraepithelial lymphocytosis: signs ofcoeliac disease. The symptoms disappeared when the patient started to use a gluten-free diet. The haemoglobin level also normalised. Coeliac disease must be considered in the differential diagnosis of iron-deficiency anaemia.
