Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Devices - Atmo gas capsule
Treatment: Devices - SmartPill

Other: SmartPill and Atmo capsule - The SmartPill and Atmo gas capsule will be tested simultaneously. This will allow the ability of the Atmo gas capsule to measure gastrointestinal transit time to be compared to the SmartPill. The order of swallowing will be randomised using a computer-generated list. The two capsules will be swallowed within 5 minutes of each other


Treatment: Devices: Atmo gas capsule
The Atmo Gas Capsule measures the capsules location and motility/transit times through gas sensing capabilities

Treatment: Devices: SmartPill
The SmartPill measures the capsules location and motility/transit times through pH sensing

Eligibility
Key inclusion criteria
* Diagnosed with gastroparesis (idiopathic or diabetic) for at least 12 weeks (based on scintigraphy results) and able to eat orally.
* Diagnosed with slow transit constipation for at least 12 weeks (exclusion of constipation caused by structural abnormalities with colonoscopy, and confirmation of slow transit by 'marker studies' such as scintigraphy, radiolabelled or opaque X-ray study).

* An endoscopy or gastrointestinal barium series within the past 3 years showing no organic disease that is potentially causative of symptoms.
* Ability to stop medications that may alter gastric pH (such as proton pump inhibitors) for 3 days prior to and during study.
* Ability to stop medications that may alter gastrointestinal motility (GLP-1 angonists, anticholinergics, cannabinoids, metformin, antispasmodic, prokinetics) for 3 days prior to and during study.
* Ability to stop antibiotic, probiotic and, prebiotic supplements 7 days before prior to and during study.
