The disorder is most commonly caused by an inherited deficiency in flavin monooxygenase 3, the vital enzyme for the metabolism of trimethylamine, which is the compound responsible for the unpleasant odor.
How common is fish odor syndrome?
Trimethylaminuria, or TMAU, is a very rare condition that makes your sweat, breathe, saliva and pee smell like rotten fish or rotten eggs. TMAU can’t be cured. But making changes in your diet, using certain soaps and lotions and managing stress can help reduce symptoms.
How do you get rid of fishy body odor?
There is currently no cure for trimethylamine, so treatment focuses on managing and reducing symptoms. People can reduce the odor of trimethylamine by avoiding substances that increase production or levels of trimethylamine in the body, such as lecithin and choline.
What body systems are affected by fish odor syndrome?
Summary. Trimethylaminuria causes the body to produce a fishy odor that is released in the sweat, urine, breath, and reproductive fluids. People with Trimethylaminuria are unable to break down trimethylamine.

What food causes trimethylaminuria?
Trimethylamine is normally formed by bacterial action in the intestine on choline (found in foods such as soy, liver, kidneys, wheat germ, brewer’s yeast, and egg yolk), or on trimethylamine N-oxide (found in salt water fish).
Is there a test for trimethylaminuria?
A urine test is used to diagnose trimethylaminuria. The person’s urine is tested to look for higher levels of trimethylamine. Testing can be done by giving choline by mouth followed by urine collection a certain number of times over a 24 hour period.
How does smell interact with other body systems?
Smells are handled by the olfactory bulb, the structure in the front of the brain that sends information to the other areas of the body’s central command for further processing. Odors take a direct route to the limbic system, including the amygdala and the hippocampus, the regions related to emotion and memory.

How do you get trimethylaminuria?
TMA is formed by bacteria in the mammalian gut from reduction of compounds such as trimethylamine-N-oxide (TMAO) and choline. Primary trimethylaminuria sufferers have an inherited enzyme deficiency where TMA is not efficiently converted to the non-odorous TMAO in the liver.
