I called a clinic to schedule an appointment to be tested for metabolic disorder. This is not just a small clinic. This clinic is connected with a university re research, etc.. I talked to the nurse and told her I believe I have borderline metabolic disorder coz certain foods cause me to smell bad like dairy, red meat, etc.. She was very nice and she said she will talk to the doctor/director for my appointment. She called me and told me their director hasn't heard anything about metabolic disorder that ONLY cause odor. It's accompanied with other symptoms. If a specialist/expert doctor hasn't heard about this then this is really hard to cure.
I should have mentioned TMAU but forgot. Anyway, I could cross out metabolic disorder doctor in my list to do/see as they won't be of any help.
Maybe I don't really have metabolic disorder and it's something else causing this odor.
