Moderate

Vitamin B complex (applies to Vitamin B1) malabsorption

Moderate Potential Hazard, High plausibility. Applicable conditions: Malabsorption Syndrome, Alcoholism, Cirrhosis

The B vitamins are readily absorbed in the GI tract following oral administration. However, GI absorption may be decreased in patients with malabsorption syndromes and other conditions. For example, the absorption of thiamine and pyridoxine may commonly be decreased in alcoholics and in patients with cirrhosis. Likewise, riboflavin absorption may be impaired in patients with hepatitis, cirrhosis, or biliary obstruction. When malabsorption of these vitamins is suspected, parenteral administration may be appropriate.
