Nedostatek thiaminu v potravě se projevuje anorexií, přecitlivělostí a hubnutím. Později se k tomu přidruží slabost, periferní neuropatie, bolesti hlavy a tachykardie. Tento deficit může být způsobený špatnou výživou a také alkoholismem (etanol ruší absorpci thiaminu). Nemoc beri-beri je častá v zemích, kde je hlavní potravinou loupaná (leštěná) rýže.

A nutritional condition produced by a deficiency of THIAMINE in the diet, characterized by anorexia, irritability, and weight loss. Later, patients experience weakness, peripheral neuropathy, headache, and tachycardia. In addition to being caused by a poor diet, thiamine deficiency in the United States most commonly occurs as a result of alcoholism, since ethanol interferes with thiamine absorption. In countries relying on polished rice as a dietary staple, BERIBERI prevalence is very high. (From Cecil Textbook of Medicine, 19th ed, p1171)
