SIBO Symptoms

The main symptoms of SIBO are those of Irritable Bowel Syndrome (IBS).  SIBO has been shown to exist in up to 84% of IBS patients and is therefore theorized to be the underlying cause.  It is associated with many other disorders as well, as an underlying cause or as an aftereffect of the pre-existing disease.

In particular, if the symptoms of IBS are present, or one of the associated diseases along with digestive symptoms is present, consider SIBO.

According to Bures et al, "It is mandatory to consider SIBO in all cases of complex non-specific dyspeptic complaints (bloating, abdominal discomfort, diarrhea, abdominal pain), in motility disorders, anatomical abnormalities of the small bowel and in all malassimilation syndromes (malabsorption, maldigestion)."
