Phone: 617-249-7300, Danbury, CT office 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. TMAU is listed as a rare disease, which means that TMAU, or a subtype of TMAU, affects less than 200,000 people in the US population. When the normal metabolic process fails, trimethylamine accumulates in the body, and its odor is detected in the .

Trimethylamine enters the body via the consumption of certain foods and supplements. What Disease States May be related to Trimethylaminuria? "It's like living with a death sentence - I wouldn't wish it on my worst enemy, it's that bad," she said. Study participants experienced subjective reduction in odor as well as objective reduction in TMA and increase in TMAO concentration measured in their urine. [5] When taken in large quantities (12g/day) betaine has been known to cause fish odor symptoms,[7] meaning that there is some conversion of betaine to TMA if supplements are taken regularly. This means trimethylamine builds up in the body and gets into bodily fluids like sweat. The aim is to set a lifestyle of successful malodor management and a well balanced diet, as much as possible. There are more than 40 known mutations associated with TMAU. In fact, trimethylaminuria is the main reason behind tuna or fish smelling urine. 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.
