Small Intestinal Bacterial Overgrowth

–10 Signs that You May have Small Intestinal Bacterial Overgrowth (SIBO)–

By Dr. Julie Gorman–


If you have ever eaten something and within a few hours realized that your abdomen is bloated and uncomfortable or if you feel chronically bloated, tired and achy, you may have small intestinal bacterial overgrowth (SIBO).


What is SIBO?

SIBO, small intestinal bacterial overgrowth, is defined as an increase in the number of bacteria and/or changes in the types of bacteria present in the small bowel. These pathogenic bacteria can lead to poor digestion and absorption as well as nutritional deficiencies, increased inflammation, food sensitivities and other non-digestive symptoms such as body aches, chronic fatigue and autoimmune illnesses.

10 Potential Signs of SIBO:

  1. Abdominal bloating (gas) – flatulence, belching
  2. Abdominal pain or cramping
  3. Diarrhea, constipation or both
  4. Heartburn and/or nausea
  5. Diagnosis of irritable bowel syndrome, leaky gut or inflammatory bowel disease
  6. Food intolerances such as: gluten, casein, lactose, fructose and more
  7. Frequent headaches, joint pain, or fibromyalgia
  8. Chronic illness such as: chronic fatigue syndrome, diabetes, neuromuscular disorders and autoimmune diseases
  9. Vitamin and mineral deficiencies such as:  vitamin B12, vitamin D, magnesium and others
  10. Fat malabsorption


How to Test for SIBO:


Lactulose Breath Testing is the gold standard test to diagnose SIBO. In this 3-hour test, a non-absorbable sugar solution (lactulose) is swallowed and hydrogen and methane gases are measured in the breath. Gas levels rise as the sugar solution passes through the intestine resulting from fermentation of the sugar by bacteria. If the gas levels rise quickly and to an abnormal level, a diagnosis of SIBO can be made and treated. Test preparation includes a special diet the day prior and a 12-hour fast the night prior to testing.


Treating SIBO:


Similar to conventional treatment that uses pharmaceutical antibiotics, our research is focused on using an antimicrobial herbal formula to eradicate the bacterial overgrowth. Our holistic treatment approach also includes a clinically researched eating plan to reduce the food sources for the unhealthy gut bacteria and to heal and restore balance to the digestive system.

  1. Will I need to discontinue my PPI medication prior to getting tested for sibo. The reason I ask is because I get bad acid rebound when I do not take my pill. Lastly, what is the cost for sibo testing?
