Many types of gases are produced within our digestive systems. Alterations in the type and amount of these gases can alter gut function, and potentially be a sign of disease.

To test the capsules, pigs on high or low fibre diets were given the capsules. Pigs on a high fibre diet had higher concentrations of carbon dioxide (CO2) and lower hydrogen gas (H2) within their gastrointestinal tract than pigs given a low fibre diet. These findings were consistent with previous studies which measured gases in the guts of pigs on low and high fibre diets using classical (more invasive) techniques. As such, this study has shown that intestinal gas capsules can effectively provide information on the "where and what" regarding gas production in the gut, information that can only be determined presently by invasive techniques that are not possible to perform on humans.
