What are the signs and symptoms of trimethylaminuria?

Trimethylamine accumulates in the body of individuals with trimethylaminuria. The trimethylamine gets released in the person's sweat, urine, reproductive fluids, and breath, giving off a strong fish-like odor. This odor may be constantly strong for some people with trimethylaminuria, but most of the time the odor is moderate and varies in intensity. Individuals with this condition do not have any physical symptoms, and typically appear healthy.[1]
