SIBO can be a cause of many health problems, including diarrhea, abdominal pain, and protein/fat malabsorption. In recent years, there has been renewed interest in SIBO since it has now been implicated in the pathophysiology of certain diseases previously not classically associated with overgrowth. The World Journal of Gastroenterology claims a definitive association between irritable bowel syndrome (IBS) and SIBO, suggesting that SIBO be excluded before diagnosing a patient with IBS.
How Is The Test Performed?
1. There is a 24-hour preparation phase before the test is performed.
2. In the first 12 hours, dietary restrictions must be followed. The patient must avoid all grains, fruit in all its forms, sugar in all its forms, dairy in all its forms, vegetables, nuts and seeds, alcohol and beans. Refer to the test kit instructions for permitted foods.
3. The last 12 hours is a fasting period. Only water can be consumed.
4. Included in the test kit is a packet of lactulose or glucose that is to be mixed with 8 ounces of water then set aside.
5. Collect a baseline breath sample before consuming the glucose or lactulose mixture.
6. After collecting the baseline breath sample, drink the mixture.
7. Fifteen minutes after consuming the lactulose or glucose mixture, breath sample #2 is collected. Breath samples are collected every 15 minutes thereafter until all tubes are used.
