Trimethylamine comes from specific chemicals (choline, carnitine, TMAO) found in certain foods. [5] The proportion of precursor converted to TMA is related to the amount of specific bacteria in the gut.[6]. In trimethylaminuria, the body is unable to turn a strong-smelling chemical called trimethylamine produced in the gut when bacteria break down certain foods into a different chemical that doesn't smell.

Several reports have concluded that symptoms can worsen at the time of puberty and there is also evidence that symptoms get worse just prior . In order to determine a diagnosis, your physician must rule out other disorders that may be causing an uncontrollable body odor. [2][3] When FMO3 is not working correctly or if not enough enzyme is produced, the body loses the ability to properly convert trimethylamine (TMA) from precursor compounds in food digestion into trimethylamine oxide (TMAO), through a process called N-oxidation. A fish-like body odor could result from excess consumption of TMA precurors choline, carnitine and betaine (unobtainable via regular dietary intake, it requires high levels of supplement intake). Symptoms develop when the ability of the liver enzyme (flavin-containing monooxygenase 3) is insufficient to break down (metabolize) the excess trimethylamine. The incidence is about 1 in 40,000 and all ethnic groups are affected.

Drug substrates may also impair metabolism in TMAU individuals. Allerston CK, Vetti, HH, Houge G et al. Testing includes organic acids, amino acids, acylcarnitine profiling and intermediary metabolites as well as the more specialist assays including sterols, trimethylamine, bile salts and quantitation of a range of compounds by gas chromatography mass spectrometry (GS/MS). If FMO3 enzyme production is compromised, or there is too much TMA for the amount of enzyme, then TMA will continue to circulate in the bloodstream until enough enzyme is produced. "When I'm on a bus I hear comments like 'oh that smells like a toilet' and 'gutter' and every odour name in the book, I've heard it all," she said.
