Okay. Breathe.

You've just been told you have trimethylaminuria, and right now your head is probably spinning. Maybe you've never heard this word before, or maybe you spent years suspecting something was wrong and finally have a name for it. Either way, it's a lot. So let's start with the most important thing: you are not broken, you are not dirty, and you are not alone. Let's break this down together, one step at a time.

What the word actually means

Trimethylaminuria is a condition where your body has trouble breaking down a chemical called trimethylamine. That's a mouthful, so let's just call it TMA. TMA is produced naturally in your gut when you eat certain foods - things like fish, eggs, liver, and some beans. Your gut bacteria make it as they digest these foods. In most people, the liver takes TMA and processes it into a different chemical that has no smell at all. But in people with trimethylaminuria, this process doesn't work properly, and the TMA stays in your body instead of being neutralized.

So what happens to that unprocessed TMA? It gets released through your sweat, your urine, and even your breath.
