As trimethylamine builds up in the body, it causes affected people to give off a fish-like odor in their sweat, urine, and breath. The intensity of this odor may vary over time. The strong body odor can interfere with many aspects of daily life, affecting a person's relationships, social life, and career. Some people with trimethylaminuria experience depression and social isolation as a result of this condition.
What causes fish odor syndrome (trimethylaminuria)?
Comment on this
Although gene mutations account for most cases of trimethylaminuria, the condition can also be caused by other factors. A fish-like body odor may result from an excess of certain proteins in the diet or from an increase in bacteria that normally produce trimethylamine in the digestive system. A few cases of the disorder have been identified in adults with liver or kidney disease. Temporary symptoms of this condition have been reported in a small number of premature infants and in some healthy women at the start of menstruation.
