SIBO, or Small Intestinal Bacterial Overgrowth, is a common digestive disorder that affects many people around the world. It occurs when there is an overgrowth of bacteria in the small intestine, leading to a variety of uncomfortable symptoms such as bloating, gas, diarrhea, and abdominal pain. If left untreated, SIBO can have a significant impact on a person’s quality of life.

What is SIBO?

SIBO is a condition characterized by an excessive amount of bacteria in the small intestine. Normally, the small intestine should have a relatively low bacterial count compared to the large intestine. However, in individuals with SIBO, the bacteria from the large intestine migrate into the small intestine, leading to an overgrowth. This can disrupt the normal digestion and absorption of nutrients, causing the symptoms associated with SIBO.

How is SIBO Testing Done?

There are several methods used to test for SIBO, including breath tests and microbial cultures. The most common test is the breath test, which measures the levels of hydrogen and methane gas produced by the bacteria in the small intestine. To perform the test, a patient will consume a solution containing a specific type of sugar, such as lactulose or glucose. As the bacteria in the small intestine break down the sugar, they produce hydrogen and methane gas, which can be detected in the breath.

Understanding the Results

The results of a SIBO breath test are typically reported as either positive or negative, indicating the presence or absence of an overgrowth of bacteria in the small intestine. However, it is important to note that interpreting the results of a SIBO treatment can be complex and should be done by a qualified healthcare professional. A positive result does not necessarily mean that a person has SIBO, as there can be other factors that contribute to a positive test, such as a recent infection or certain medications.


SIBO testing is an important diagnostic tool used to identify and manage small intestinal bacterial overgrowth. By understanding the basics of SIBO testing, individuals can take steps towards seeking proper diagnosis and treatment. If you are experiencing symptoms of SIBO, it is recommended to consult with a healthcare professional who can guide you through the testing process and develop an appropriate treatment plan.
