Thiamin, Pyridoxine, Vitamin D, and Carotene Deficiency in a Malnourished Patient Following Billroth II Gastrectomy.

We describe the case of a malnourished 48-year-old man who had previously undergone a Billroth II procedure for severe peptic ulcer disease. He was found to have a severely stenotic gastrojejunal anastomosis with inflamed mucosa that prevented him from tolerating solid food. Laboratory assessment revealed deficiencies in thiamin, pyridoxine, vitamin D, and carotene. This case demonstrates potential vital micronutrient complications following a partial gastrectomy.
