Thank you so much, @lizbee78! I can’t thank you enough for responding so quickly and letting me know with whom you worked. May I ask just one more question? The GI doctor I met with last time suggested that since the Hydrogen & Methane levels didn’t peak until the 90+ minute, it likely was coming from my colon and thus wasn’t SIBO. If you’d be comfortable sharing with me, did you experience high levels of hydrogen and/or methane before the 90 minute mark?
