Trimethylaminuria causes fish smells Those who suffer from trimethylaminuria know how difficult and uncomfortable it is to smell fish even though they bathe more than twice a day and use deodorant.
According to a study by the Monell Chemical Senses Center in Philadelphia , the bad body odor of some humans is generated by a genetic disorder called trimethylaminuria (TMAU).
People suffering from this metabolic disorder are unable to metabolize the trimethylamine , organic compound causing the smell of fish and ammonia.
Data from the World Health Organization (WHO) this disease affects 300 to 600 people around the world.
