Trimethylaminuria is a rare disorder of metabolism characterized by a defect in the production of the enzyme flavin-containing monooxygenase 3 (FMO3) FMO3 is important for converting trimethylamine into trimethylamine oxide. However, The gut microbiome affects many aspects of human health, and the foods people eat can have a huge impact on the bacteria in their gut. If the FMO3 enzyme does not work properly, the body is unable to break down trimethylamine, and the chemical builds up in the body. Some people with trimethylaminuria have a strong odor all the time, but most have a moderate smell that varies in intensity over time. Other than the strong fishy odor, individuals with this condition typically appear healthy. The condition seems to be more common in women than men, but scientists don't know why. Trimethylaminuria is usually inherited in an autosomal recessive fashion, which means that two non-functioning FMO3 genes are usually needed for a person to have symptoms.

But like typical body odor or sweat, some people with TMAU may be accustomed to the smell and less likely to react to it than those around them. Healthcare providers call this primary trimethylaminuria. Some people may have trimethylaminuria because they have an inherited metabolic condition that blocks the enzyme from breaking down trimethylamine. Here, we look at the causes, symptoms, and treatment of trimethylaminuria. People assigned female at birth (AFAB) or more likely to have TMAU than people assigned male at birth (AMAB).
