I think in Brazil don´t have a place that test SIBO.I read the article about SIBO.The sympthoms are described are the same i have: excess gas, abdominal bloating and distension, diarrhea, and abdominal pain.I started to have these sympthoms after i had my gallbladder removed. I was diagnosticated with IBS.I remember that the 2 weeks after the sugery, i took a lot of antibiotics. Maybe it can be the cause of SIBO. Where i can read about dr.Pimentel´s protocole?Thanks and i hope you understand. I´m brazilian and i have to improve my english,André
