Vitamin D deficiency following Billroth II surgery - How much vitamin D is enough?: a case report.
BACKGROUND
Vitamin D deficiency with all its consequences is a global health problem.


METHODS
We reported a 62-year-old Caucasian woman with alcohol-related liver cirrhosis (Child class A) and a medical history of Billroth II surgery. Although she has taken an oral dose of 16 800 IU vitamin D daily for six weeks to normalise her 25-hydroxyvitamin D level the raise was only moderate.


CONCLUSIONS
High-dose oral or parenteral vitamin D therapy is necessary to gain sufficient 25-hydroxyvitamin D serum levels in patients following gastric surgery.
