What is SIBO  – Small intestine bacterial overgrowth?

Well, quite simply SIBO is a condition where levels of bacteria in the small intestines, both good and bad bacteria, are higher than they should be.

SIBO affects people in many different ways. Digestive issues are most common with bloating, constipation and/or diarrhoea, gas, flatulence, belching, cramps and discomfort being typical, Research shows that small intestine bacterial overgrowth (SIBO) is responsible for up to 78% of cases of IBS (ref.) 

SIBO is a complicated condition though and it can cause a very broad range of symptoms. Often missed as a contributory factor to many health issues, SIBO can play a part in chronic fatigue (CFS), rosacea, restless legs, cystitis,  prostate issues and many more health concerns

Most common SIBO symptoms:

  • Diarrhoea – usually associated with hydrogen-dominant SIBO

  • Diarrhoea or constipation with hydrogen sulphide-dominant SIBO
  • Alternating constipation and diarrhoea
  • Gas
  • Flatulence
  • Belching
  • Severe bloating
  • Abdominal pain and cramps
  • Leaky gut  – intestinal permeability

Other related digestive SIBO symptoms:

What causes SIBO – Small Intesine Bacterial Overgrowth

Research shows the main cause of small intestinal bacterial overgrowth (SIBO) is a reduction or slowing of motility (the movement of food) through the gut impacting on the levels of bacteria present in the small intestines. Think of a stagnant pond where bacteria flourish and grow in large unwanted amounts opposed to a clean, free-flowing stream which keeps bacteria levels as they should be.

There are two main causes of slowed motility in the gut:

1. The cleansing sweeping action ‘Migrating Motor Complex’ MMC in the gut stops working properly. The MMC makes cleansing, sweeping-like motions between meals that “clean” the small intestine. This should move undigested food and excess bacteria towards the large intestines. When the MMC is faulty, undigested food becomes food for the bacteria causing or exacerbating SIBO. The major cause of malfunctioning MMC is food poisioning.

2. Structural changes which affect the motility of the gut can also cause SIBO. Some diseases, medical conditions and procedures can cause these structural changes. For example, scarring after operations, inflammatory bowel disease, diverticulosis, blind loops, radiation damage, stricture, fistulas, intestinal pseudo obstruction and adhesions resulting from surgery are all known to impact on or cause SIBO.

Contributory and risk factors that can affect SIBO:

  • Low stomach acid – hypochlorhydria
  • Drug-induced hypoacidity (low stomach acid) – commonly seen on those that take PPI’s (proton pump inhibitors)
  • Inflammatory bowel disease
  • Chronic alcohol use
  • Celiac disease
  • Chronic pancreatic insufficiency
  • Lactose intolerance (the type of natural sugar found in dairy products)
  • Damaged ileocecal valve
  • Immunodeficiency (especially of secretory immunoglobulin A)

Gas levels of hydrogen and methane measured in PPM (parts per million) are universally used to test for SIBO.

You can complete the SIBO Test easily at home.
