Deficiency

The disease beri-beri from a lack of dietary vitamin B1 is found today in very poor population groups (e.g. refugees) in developing countries and people who eat mostly polished / white rice. A typical image consists of nervous disorders, especially peripheral nerves (dry beri beri), edema and heart disease (beri beri wet). Impaired absorption of vitamin B1 occurs in alcoholics and manifested by Wernicke encephalopathy. Suboptimal thiamine status based on biochemical criteria in Europe was detected only in 4-6% of the population. Risk group are alcoholics. Laboratory evaluation: thiamine excretion in the urine. In the absence of erythrocytes is reduced transketolase concentration in the blood and the sea is high concentrations of glycoxalate
