Study: NCT04910815

Intervention type: DEVICE
Group type: PLACEBO_COMPARATOR
Intervention: Atmo Gas Capsule
Description: The Atmo gas capsule is an ingestible electronic device. This capsule consists of gas and temperature sensors, electronic circuits, radio transmitter and silver oxide batteries. It can measure the concentrations and types of intestinal gases in individuals and give an indication of gut transit time. This data is used for research purposes to gain an understanding of the microbiota's localised functionality. The data from the sensors is transmitted out of the body over the radio frequency to a handheld receiver. The capsule passes out of the human body at the end of the measurement and is disposable.

Intervention: Glucose Breath Test
Description: Glucose is a sugar that will be broken down by bacteria if present in the small bowel with hydrogen gas as a by-product. The hydrogen produced through fermentation is measured in the patients exhaled breath
