What is SIBO?

Small Intestine Bacterial Overgrowth(SIBO) is when bacteria that normally lives in your large intestine end up migrating to and begins living in your small intestine. The large intestine has 17 times more bacteria than the small intestines and overgrowths of bacteria in the small intestines interrupts its primary functions; nutrient absorption and immune regulation. Additionally, bacteria that normally live in the large intestines produce by-products, hydrogen and methane gasses, normally not seen in the small intestines that further disrupts intestinal functioning. When these gasses are in your small intestine, they can cause a multitude of problems and symptoms. Additionally, excessive gut bacterial activity also leads to increased metabolic by-products including ammonia and other toxic chemicals that disrupt liver health and hormone detoxing. Studies have indicated that potentially up to 80% of patients with IBS have SIBO which a Hydrogen/Methane Breath Test can easily and non-invasively help determine.

Who should perform a breath test?

Breath testing may be be indicated if you experience any of these symptoms:

  • Gas, bloating, reflux or heartburn

Frequently Asked SIBO Testing Questions​

What is lactulose?

Lactulose is a manmade sugar that humans cannot digest, but SIBO bacteria love; acting like fertilizer for SIBO bugs. Drinking lactulose will not cause the same “sugar-high” as sugars that humans can digest (like sucrose or fructose). Lactulose is also used as a laxative, so some people may experience effects of needing to use the restroom during the test. Sometimes people may feel an exasperation in symptoms caused by SIBO activity (like bloating, gas), but some people do not experience any at all.

Is Lactulose the same as Lactose?

No. Lactose is the sugar from milk, while lactulose is a completely different chemical makeup that is manmade. The lactulose that comes in the SIBO kits is a liquid solution. This solution, however, does contain 1.2 grams of lactose in it, so people who are severely lactose intolerant should ask their doctor if this test is right for them.


Which medications will affect the outcome of a hydrogen breath test?

Below is a list of medicine and duration they need to be avoided prior to breath testing:

Narcotics: 1-4 days before testing (4-days is ideal)

Laxatives (such as Metamucil, Dulcolax, Ex-Lax): 4-days before taking test

Antibiotics: 4 weeks before taking test (2 weeks in some cases)

Antifungals​: 2 weeks before testing

Probiotics: 4 days before taking test

High doses of Magnesium, Vitamin C, etc. 4- days before testing. Anything you are taking to stimulate your bowel moments should be avoided 4-days before testing.
