Can the high levels of trimethylamine and fishy smell just involve the urine?

Yes, it is possible for the fish-like smell to just involve the urine, as symptoms vary from person to person in trimethylaminuria.[1] The accumulated trimethylamine may also be released in the person's sweat, reproductive fluids, and breath, giving off a fish-like odor.[1] If you or someone you know is concerned that they may have trimethylaminuria, we recommend speaking with a healthcare provider.
