Thiamine deficiency

Pronunciation: thahy-uh-meen

Vitamin B1 deficiency that can occur rapidly after bariatric surgery, potentially causing serious neurological complications.

Full Definition

A critical nutritional deficiency of vitamin B1 (thiamine) that can develop within weeks to months following bariatric surgery, particularly in patients with persistent vomiting or poor dietary intake. Thiamine deficiency can progress to beriberi or Wernicke encephalopathy, causing symptoms ranging from fatigue and confusion to permanent neurological damage. Prevention requires adequate thiamine supplementation and prompt recognition of early symptoms in high-risk patients.
