title: [Anemia in primary care: etiology and morphological characteristics].
abstract: OBJECTIVE
  To find the morphological characteristics and causes of the types of anaemia seen at a primary care centre.
  
  
  METHODS
  Descriptive, observational study.
  
  
  METHODS
  Urban health centre.
  
  
  METHODS
  People attending for a year who had an anaemia defined by haemoglobin figures below 13 g/dl in males and 12 g/dl in women.
  
  
  RESULTS
  152 patients with anaemia were identified. The most common types of anaemia were iron-deficiency anaemia (IDA), anaemia due to chronic illness (ACI) and post-haemorrhage anaemia (48%, 26.3% and 6.6%, respectively). Anaemia due to vitamin B12 deficit was detected in four patients, Thalassaemia minor in two, haemolytic anaemia in two, and a refractory anaemia in one patient. The most common cause of IDA was gynaecological in origin; and the commonest cause of ACI was neoplasm. The main findings of digestive origin in IDA were oesophagitis in two patients, duodenal ulcer in one, erosive gastritis in one, gastric neoplasm in one, colonic neoplasm in two and Crohn's disease in one. 13.7% of the anaemia studied in PC required hospital referral.
  
  
  CONCLUSIONS
  Anaemia is a common health problem in primary care (PC), with a rough incidence of one case per month per doctor. Its main types are iron-deficiency anaemia and anaemia due to chronic illness. Most cases were detected in PC and most can be studied properly at this care level.
