Registry studying bacteria patterns in suspected small bowel overgrowth
This is a research registry that collects small-bowel fluid samples from people being tested for “SIBO” (an overgrowth of bacteria in the small intestine). It aims to describe what bacteria are present and how results differ between people with suspected SIBO and others having similar tests for other reasons.
Indianapolis, IndianaAges 18–90 - NCT07261228Recruiting
Comparing carbon footprint of diagnostic vs. therapeutic upper endoscopy
This study looks at how much carbon dioxide is released during upper endoscopy, comparing people having a diagnostic procedure for stomach discomfort versus those having treatment for a bleeding ulcer. It may help understand which type of procedure has a bigger environmental impact.
