Small Intestinal Bacterial Overgrowth (SIBO)

Small Intestinal Bacterial Overgrowth (SIBO) is a condition in which there is an overgrowth of bacteria in the small intestine. Normally, the small intestine contains a small number of bacteria, but in SIBO, the number of bacteria is much higher than it should be. This can cause a range of symptoms, including bloating, gas, diarrhea, abdominal pain, and fatigue.

SIBO is a common condition, affecting an estimated 10-20% of the population. It is more common in women than men and in people over the age of 50.

At VITALIZE, we specialize in the diagnosis and treatment of SIBO. Our team of expert clinicians is dedicated to helping patients with SIBO find relief from their symptoms and improve their quality of life.

Causes of SIBO

Several factors can contribute to SIBO, including:

  • Decreased stomach acid: Stomach acid helps to kill bacteria in the small intestine. If stomach acid levels are low, it can allow bacteria to grow out of control.
  • Intestinal damage: Damage to the small intestine from food poisoning, surgery, or radiation can impair intestinal motility. If motility is impaired, food can stay in the small intestine for longer, giving bacteria more time to grow. 
  • Medications: Medications such as proton pump inhibitors and antibiotics
  • Medical conditions: Certain medical conditions, such as Crohn’s disease and celiac disease, can increase the risk of SIBO.

Symptoms of SIBO

The symptoms of SIBO can vary from person to person, but common symptoms include:

  • Bloating
  • Gas
  • Diarrhea
  • Constipation
  • Abdominal pain or discomfort
  • Nausea
  • Fatigue
  • Malnutrition

If you are experiencing any of these symptoms, it’s important to seek medical attention.

Associated conditions

SIBO is associated with several diseases including Celiac Disease, hypothyroidism, liver disease (cirrhosis, NASH/NAFLD), diabetes, ​GERD (Gastroesophageal Reflux Disease), IBD (Inflammatory Bowel Disease), IBS (Irritable Bowel Syndrome), obesity, pancreatitis, Parkinson’s Disease, restless legs syndrome, rosacea, scleroderma, and many more.  It is speculated that SIBO is the cause of IBS in up to 84% of IBS patients.


Diagnosing SIBO can be tricky because the symptoms are similar to other digestive conditions. After obtaining a thorough medical history your doctor may order a breath test to measure the amount of hydrogen, hydrogen sulfide, and methane gas in your breath, which can indicate the presence of SIBO. If the gas levels are elevated, it may indicate the presence of SIBO.  Blood tests, stool tests, and imaging tests may also be used to rule out other conditions. At VITALIZE, we use the latest diagnostic tools and techniques to accurately diagnose SIBO and determine the best course of treatment for each patient.


At VITALIZE, we offer a range of treatments for SIBO, including:
  • Antimicrobials: Antimicrobials are often used to kill the excess bacteria in the small intestine. We use a targeted approach to prescribing conventional antibiotics or herbal to minimize the risk of side effects.
  • Diet: Specialized diets can help reduce the symptoms of SIBO. Our team can help recommend a personalized nutrition plan for each patient.
  • Lifestyle changes: Lifestyle changes such as stress management and exercise can also help reduce SIBO symptoms.

At VITALIZE, we believe in taking a holistic approach to treating SIBO. We work closely with each patient to develop a personalized treatment plan that addresses their unique needs and goals using naturopathic and functional medicine.
