Full Study Name
Exploring the Role of Hydrogen Sulfide in Diarrheal Conditions (IRB no. 54140)
The purpose of this study is to find ways to decrease levels of a gas called hydrogen sulfide. Hydrogen sulfide gas is made by microbes (bugs) in the gut and is linked to small intestinal bacterial overgrowth (SIBO). SIBO is a condition in which there is an excess amount of microbes within the gut (specifically, the small intestine), which can lead to symptoms such as abdominal pain and diarrhea. Researchers aim to test various ways of decreasing levels of the microbes that produce hydrogen sulfide gas, and therefore provide relief from SIBO symptoms.
Researchers will compare levels of hydrogen sulfide gas among participants and will use samples to test potential treatments. This study involves the investigational use of Integrated Breath Sample System (IBS-S).
