@j77 OMG you just wrote all my GI symptoms under the sibo name!! I am suffering from B12 and iron deficiency. Labs have confirmed it for months and docs acknowledge but pass it off to the next doctor. I don't have a large intestine (sigmoid colon). It was taken when bowel perforation occurred! With my thyroid also missing I have a difficult time with metabolism. I'm seeing Gastro doc next week!! Glad I now have this info to share with him and also when I do take antibiotics I do feel better!! Thank you so much !!! 😁😁
