Interesting a bit too technical for me though I will have to read it piecemeal to take it in.
However from reading posts on here and now mentioned in the article I could blame the origins of my AS to a bout of illness (severe both ends at once and only me) some of what I now know were mild AS symptoms began soon after.
I then suffered an episode 7-9 years later of possibly Norovirus followed by monthly recurrent week long upsets with a food poisoning episode in between
I think I went downhill after that. The Norovirus (baby 11 months old) was post caesarean and antibiotics for a post op infection plus antibiotics for mastitis before I discovered a drug free remedy for mastitis
. Previous to my caesarean I had never had any antibiotics previous to my caesarean and never suffered any major stomach upsets/food poisoning.
It is all to do with the gut IMHO.
