Breath tests

Breath tests typically involve ingestion of a substrate that is then metabolized by gastrointestinal bacteria or digestive enzymes. The metabolites of the ingested substrate are then measured in the exhaled breath of the patient.

Various breath tests help diagnose conditions such as

Wireless capsule motility

Wireless capsule motility involves an ingestible device that continuously measures the pressure and pH of the intraluminal environment as the device travels through the gastrointestinal tract. It allows the measurement of transit time, pressure profile, and motility of the entire gastrointestinal tract and individual regions (stomach, small intestine, colon). This procedure can help assess gastric emptying as well as small-bowel and colonic transit in patients presenting with symptoms suggestive of dysmotility.
