Overview

Thiamine deficiency can generally result from inadequate intake (as with anorexia or alcoholism), increased losses (as with excessive vomiting), and inadequate absorption (as after bariatric surgeries)

Causes

Thiamine deficiency can be a result of:

1. Inadequate intake:

• Alcoholism
• Anorexia
• Intentional dieting
• Starvation
• Bulimia
• Protein energy malnutrition in developing countries
• Total parenteral nutrition
• Infants breast fed by thiamine deficient mothers

2. Increased losses:

• Protracted vomiting in chemotherapy patients
• Hyperemesis gravidarum in pregnant women

3. Inadequate absorption:

• Post gastric bypass surgery patients
• Genetic loss of ability to absorb thiamine
