Thiamine deficiency is known to occur in all of the following, EXCEPT:: (A) Food Faddist, (B) Homocystinemia, (C) Chronic alcoholic, (D) Chronic hea failure patients on diuretics
Answer is B. Homocystinemia is a cause of folate deficiency, not thiamine. Food Faddism, chronic alcoholism and chronic hea failure patients on diuretics are causes of thiamine deficiency. Other at-risk populations are women with prolonged hyperemesis gravidarum and anorexia, patients with overall poor nutritional status on parenteral glucose and patients after bariatric bypass surgery.
