What is Beri Beri?

This condition is mostly seen on a background of prolonged ingestion of alcohol. It is present in more than 80% of cases of Wernicke-Korsakoff’s disease.

The development of vitamin B1 deficiency in chronic alcoholics is due to low intake, impaired absorption in the digestive system and storage, accelerated destruction of Thiamin and varying degrees of energy expenditure.
