Summary

The researchers are trying to find out more about Gastric Antral Vascular Ectasia (GAVE). This is a condition that affects the blood vessels in the stomach, leading to their enlargement and possible bleeding. It can also cause symptoms such as abdominal pain and nausea. By participating in this study, you will help us learn how often these symptoms occur and how they relate to stomach functioning.

Gastric Emptying Breath Test

13C-Spirulina GEBT (Cairn Diagnostics) is non-radioactive, non-invasive breath based test validated against scintigraphy for the measurement of gastric emptying. Patients will be mailed test kits to be done in their homes remotely along with telehealth assistance from the study team. After overnight fast and providing duplicate pre-meal breath samples, the patient consumes 27 grams of re-hydrated, precisely formulated, pasteurized scrambled egg mix containing a dose of 43 mg of 13C (provided by approximately 100 mg of 13C-Spirulina), 6 saltine crackers and 6 ounces (180 mL) of potable water. The caloric value of the meal is approximately 230 kCal.Patient will provide breath samples into provided glass tubes before and after test meal administration which are then mailed back to a central laboratory for analysis by gas isotope ratio mass spectrometry.
