It’s clear now that PATM is either caused by only two possibilities.
1. a gut microbiota imbalance
2. or a faulty liver enzyme
A combination of both can also exist. The actual toxins that is causing the allergies on other people is a different story.
Btw, TMAU only refers to odors caused by the TMA smelly compound so if you’ve tested negative for the present of TMA then you either have PATM or some other odor condition other than TMAU.
What we know now is that different gut microbiota combination can lead to many and different chemical pathways that ultimately produce different compounds. One or more of those compounds (toxic to other people’s immunity) is causing an increase in gut permeability and suppressing our immunity which allows other gut incomplete digested substances and toxins to easily flood the blood stream without any immunity response.
What do we do about it? We have to try our best to balance our gut microbiota and maintain it by eating the right food. Food determines what gut bacteria we feed to thrive. They change according to the food we eat. But before that ever happens, we have to erase everything in the gut before we pour in new fresh good bacteria. When MeBO result came out pointing out leaky gut, I ordered a probiotic that only has 3 strains which best increases immunity and lowers gut permeability. Unfortunately, the probiotics I order is not in good quality because it needed continuous refrigeration. I learned on YouTube of someone who use the same 3 strains but from a different company, biogrow probiotics, with amazing results. He claims PATM disappear after that for years but occasionally shows. So it would seem that there’s proof that gut imbalance is the sole problem. We need strains with max effect on gut permeability. I still believe FMT if done properly, is the ultimate cure for this problem. When FMT is done, doctors have sufferer do a minimal of 4 days of antibiotics course to wipe everything out of the gut then after 24 hours of stoppage perform FMT, after that patient is fed on a special diet to feed those good bacteria for a while.
If there’s anything you do, aim at decreasing gut permeability and improving microbiota balance. Someone suggested he good results from drinking cabbage juice only for two weeks and gotten good results. I believe the result would be even better if taken together with biogrow probiotics which contained only the 3 stabilized strains. Combining good methods like this will help.
