The Center for Women’s Gastrointestinal Medicine performs the lactose breath test and bacterial overgrowth test.
Lactose Breath Test
This noninvasive test identifies lactose intolerance. Detection of lactose maldigestion and malabsorption enables the health care provider to counsel the patient on how to alleviate chronic symptoms of bloating, gas, diarrhea, and abdominal pain.
The lactulose breath test is used to diagnose small intestinal bacterial overgrowth (SIBO), an abnormal amount and/or type of bacteria in the small intestine that can cause bloating, gas, diarrhea, and abdominal pain. Patients swallow a non-absorbable sugar solution and the level of hydrogen gas in their breath is measured over time. Abnormal gas levels result in a diagnosis of SIBO, which can then be treated.
