title: [Gastric surgery as a nutritional risk factor].
abstract: BACKGROUND
  The stomach has a role in the digestion and absorption of nutrients, so patients are in nutritional risk after gastric resection. The aim of this work was to study the nutritional status of postgastrectomy outpatients followed in our hospital.
  
  
  METHODS
  We retrospectively studied 54 patients (27 M, 27 F) followed more than 12 months postgastrectomy. Mean age was 61 +/- 14 yr and median follow-up was 35 months. The nutritional assessment included anthropometry, biochemical data and measurement of bone mineral density by dual-energy X-ray absorptiometry. The statistical analysis was performed by non-parametric tests.
  
  
  RESULTS
  Malignancy was the most frequent indication (85%), 63% of patients had total gastrectomy. Patients were supplemented with iron (43%), B12 (87%), calcium (18%) and vitamin D (17%). 13% of patients had a BMI < 18.5. The incidence of 25 OH vitamin D deficiency and secondary hyperparathyroidism was 45% and 76%, respectively. The incidence of osteoporosis at lumbar spine was 46%. Matched with same age-sex people patients had 85.6% of bone mineral density.
  
  
  CONCLUSIONS
  The loss of weight and the metabolic bone disease were the most prevalent impairments after gastric resection. These impairments point to the importance of a nutritional surveillance of patients after gastric resection.
