SIBO Services

Diagnostic Testing

There are a number of lab tests to determine Small Intestinal Bacterial Overgrowth (SIBO) status. Breath test using either a glucose or lactulose sugar challenge, via a QuinTron breath analyzer, is the industry standard trusted by the largest medical institutions and top researchers. Natural Medicine of Stillwater is proud to be one of clinics in the state of Minnesota to run this test through our on-site lab. Our QuinTron breath analyzer is the most up-to-date unit allowing for the measurement of both hydrogen and methane gases. Because we run the testing ourselves, we offer both in-house and take-home testing options. 

In addition to breath testing, we offer additional testing to better diagnose your gastrointestinal issues. We take a holistic approach to the gut disorder diagnosis which could include: genetic, neurotransmitter, nutritional, hormonal, inflammation and autoimmune testing. 


Your SIBO diagnostics allow for a personalized treatment protocol that may include one or more of the following: herbs, antibiotics, pro-kinetics, tissue healing nutrients, amino acids, anti-inflammatories, digestive aids, immune support, probiotics and IV therapies. 

Our treatment goal is to fix your health, and we leverage all possible treatments to reach that goal. We will work with your primary care provider and other health care team members to coordinate care and minimize your out-of-pocket costs. We also have an on-staff prescribing practitioner to assist with any necessary prescriptive treatments including, but not limited to, antibiotics, antifungals, pro-kinetics, vitamin shots and nutritional IVs. 

A Holistic Approach

The brain-gut connection is a major aspect of SIBO that is often not fully addressed. SIBO can lead to the manifestation or exasperation of depression, anxiety, insomnia and/or OCD. SIBO affects the nervous system with the gut and throughout the body. SIBO activity can result in neuropathies and cognitive changes often blamed on other chronic infections, autoimmune disorders or the aging process. SIBO often results in chronic immune activity resulting in neurotransmitter imbalances, favoring patterns associated with mood disorders and fatigue.


SIBO symptoms are often mistaken for Lyme disease and SIBO is commonly a problem found in persistent Lyme disease. When co-existing with Lyme disease, SIBO symptoms often mimic past Lyme symptoms and can result in over-treating. Additionally, effectiveness of infectious disease treatments are difficult to accurately monitor if SIBO is part of the picture. 

SIBO metabolic waste products challenges the liver detox functions and can lead to sex hormone imbalances, excessive harmful estrogen metabolites, fatty liver and higher levels of ammonia. Most suffers of acne, PCOS and fatty liver suffer from SIBO. 

In order to fully recover from SIBO, it is sometimes necessary to "reboot" a number of systems and organs to improve symptoms and reduce reinfection rates. Diagnosis of SIBO is the first step, but a number of other holistic approaches are commonly needed to return to a state of optimal homeostasis.
