SIBO is small intestine bacterial overgrowth. It is when bacteria from your large intestine start living in your small intestine.
When I had SIBO, the direct cause was a parastomal hernia, the intestinal discomfort and the pain was horrible . When I got hernia repaired the SIBO was gone. (I do take two different probiotics to make sure it stays away.) While I don't think there are any direct causes or correlations, I do think having fibromyalgia did intensify the pain of the SIBO and hernia.
