Vitamin B12 deficiency presenting as intestinal pseudo-obstruction in short bowel syndrome: A case report

Abstract

Bowel obstruction and nutrient deficiencies are commonly encountered complications seen during follow-up of patients with short bowel syndrome. It is rare to see vitamin B₁₂ deficiency among micronutrient deficits. The onset of B₁₂ deficiency can be insidious, with autonomic features preceding other symptoms. In this study, we report a case in which vitamin B₁₂ deficiency presented with intestinal dysmotility mimicking mechanical bowel obstruction.
