SIBO and GI Imbalances

What is SIBO?

SIBO (Small Intestine Bowel/Bacterial Overgrowth) is a chronic bacterial and/or candida/fungal infection of the small intestine. The infection is of bacteria that normally live in the gastrointestinal tract but have abnormally overgrown in a location not meant for so many bacteria. The candida/fungal overgrowth almost always accompanies the bacteria overgrowth causing the condition known as "gut dysbiosis."

This bacteria and fungal overgrowth interferes with our normal digestion and absorption of food. It is also associated with damage to the lining or membrane of the small intestine (leaky gut syndrome). 

  • They consume some of our food which over time leads to deficiencies in their favorite nutrients such as iron and B12, causing anemia.
  • They consume food unable to be absorbed due to SI lining damage, which creates more bacterial overgrowth (a vicious cycle).
  • After eating our food, they produce gas/ expel flatus, within our SI. The gas causes abdominal bloating, abdominal pain, constipation, diarrhea or both (the symptoms of IBS). Excess gas can also cause belching and flatulence.
  • They decrease proper fat absorption by de-conjugating bile leading to deficiencies of vitamins A & D and fatty stools.
  • Through the damaged lining, larger food particles not able to be fully digested, enter into the body which the immune system reacts to. This causes food allergies/ sensitivities.
  • Bacteria themselves can also enter the body/bloodstream. Immune system reaction to bacteria and their cell walls (endotoxin) causes chronic fatigue and body pain and burdens the liver.
  • Finally, the bacteria excrete acids which in high amounts can cause neurological and cognitive symptoms.

SIBO Symptoms

The main symptoms of SIBO are those of Irritable Bowel Syndrome (IBS). IBS can exist in 3 main types: diarrhea (D), constipation (C), or alternating diarrhea and constipation. SIBO has been shown to exist in up to 80% or more of IBS patients and is therefore considered to be the CAUSE of IBS.

–belching, flatulence
