SIBO and Testing


Testing and treatment available through The Natural Medicine Center!
Dr. Kelley is accepting new patients (in-clinic or phone) and is very experienced in effective SIBO treatments.



SIBO (pronounced “see-bo”) is Small Intestinal Bacterial Overgrowth – in essence, an overgrowth of “good” bacteria in the wrong place.

These bacteria should predominately reside in our large intestine/colon. SIBO is actually a motility disorder in which the good bacteria are able to migrate up from the large intestine into the small intestine or are not effectively moved down into the colon when taken in as a supplement or food. A process called the Migrating Motor Complex (MMC) is responsible for “street cleaning” the small intestine. Also called the “cleansing wave”, the MMC creates a current that washes debris down and keeps bacteria in the colon.

For multiple reasons (poor diet of refined/ processed food, medications, etc.) this process stops allowing debris to collect and bacteria to migrate to the small intestine. The small intestine is not equipped to handle a significant growth of these bacteria as in the large intestine. When they migrate to the small intestine they are closer to a food source (as it comes through the stomach). They consume “food” (in the form of sugars – glucose, lactose and fructose), multiply, release hydrogen and/or methane gas, as well as endotoxins. This leads to small intestine damage resulting in malabsorption, inflammation, leaky gut syndrome, digestive symptoms and likely systemic symptoms.

Digestive Symptoms

  • Gas and Bloating
  • Diarrhea
  • Constipation
  • Abdominal Pain or Cramping
  • Reflux
  • Irritable Bowel Syndrome/IBS
  • Multiple Food Intolerances or “Food Allergies”
Systemic Symptoms

  • Thyroid disorders
  • Prostate disorders
  • Autoimmune conditions
  • Neurological conditions such as vertigo and seizures
  • Poor immune functioning
  • ADHD/ADD/Autism
  • Joint Pain
  • Fibromyalgia
  • Chronic Anemia or Low Mineral Status

SIBO is a fixable MOTILITY disorder. The three stages in SIBO treatment are:


  1. Eradicate the bacteria in the small intestine
  2. Repair the motility function/MMC
  3. Heal the gut through a specific diet

Either conventional or herbal antibiotics are given for a 14 day course while also addressing motility repair with an agent called a “Prokinetic”. The KEY to treating SIBO long-term is not only eradicating the bacteria in the small intestine but repairing the MMC.

The third stage in SIBO treatment is repair the damage in the gut. A very specific diet is followed for a prescribed amount of time allowing the damaged small intestine to be healed. This is often where the true healing begins.

If you think you might have SIBO the first step is to get tested! Seek treatment by a physician who understands SIBO and has a comprehensive treatment plan that includes a prokinetic as well as a healing diet otherwise SIBO will return again and again.
