[Serum level of 25 hydroxy vitamin D3 in patients with gastric and duodenal ulcers and following billroth II gastric resection].

Serum 25-hydroxyvitamin D3 levels were determined in patients with gastric ulcer, duodenal ulcer, and subtotal gastrectomy (Billroth II); 35 healthy persons served as controls. 25-hydroxyvitamin D3 levels were correlated with the signs of osteopenia determined radiologically. 25-hydroxyvitamin D3 serum level was not different from normal in subjects with gastric or duodenal ulcer. Those who underwent gastric surgery had significantly lower values. Within this group those with osteopenia had lower values than those without.
