Your healthcare provider may prescribe a short course of antibiotics to reduce your gut bacteria so you have less trimethylamine in your gut. This testing is called PGD. Early diagnosis is important to start diet changes that can minimize symptoms as soon as possible. The condition is caused by a homozygous mutation in the FMO3 (flavin monooxygenase 3) gene coding for the enzyme that converts TMA (trimethylamine) to trimethylamine N-oxide. Some people have a mutation in the gene that controls this enzyme, which prevents it from breaking down certain chemicals properly. 2005-2023 Healthline Media a Red Ventures Company.
