Thiamine deficiency is known to occur in all of the following, EXCEPT:

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.
