(Small Intestinal Bacterial Overgrowth)

What is SIBO?

Although most people may have never heard of SIBO before, it is one of the most prevalent digestive disorders, and contributes to up to 84% of IBS cases! 

It is fundamentally a dysfunction in the ability of your body's muscle contractions in the digestive system that moves contents along, from the small to the large intestine. When this doesn't work well, bacteria start to accumulate in the small intestine. This creates problems, as this area is not equipped or designed to house large numbers of bacteria. Most bacteria (up to 98%) resides in the large intestine, versus the small intestine at 2%. The imbalance created by large numbers of bacteria (can be 'good' or 'bad' bugs) can affect digestion and absorption of nutrients, and cause symptoms such as:

  • abdominal bloating
  • flatulence and burping
  • heartburn
  • diarrhea and/or constipation

Other conditions commonly associated with SIBO include:

  • Irritable Bowel Syndrome (IBS), Ulcerative Colitis, Crohns Disease
  • Acid Reflux and Heartburn (GERD)
  • Anemia and Fatigue
  • Low levels of Vitamin B12
  • Traumatic Brain Injuries (TBI) and Concussions
