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

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.
