'Smart Toilet' Scans Stool for Blood, Consistency

May 25, 2021 -- A 'smart toilet' in development uses artificial intelligence to analyze stool for consistency and presence of blood — and early evidence suggests it is more accurate than patient self-reporting.

'Smart Toilet' Scans Stool for Blood, Consistency

The remote, automated, real-time analysis and reporting increase the likelihood of doctors detecting gastrointestinal issues earlier, investigators say.

In a proof- of- concept study, the smart toilet was 85% accurate in categorizing stool consistency as loose, normal, or constipated. The findings were presented at the Digestive Disease Week ) 2021 virtual meeting.

"This study highlights a very innovative and practical tool that could have major implications for patients and clinicians alike," Andrea Shin, MD, who was not affiliated with the research, told Medscape.

"Stool form or consistency and signs of bleeding are some of the most important pieces of clinical history when it comes to GI or bowel symptoms," added Shin, assistant professor of medicine in the Department of Gastroenterology & Hepatology at Indiana University School of Medicine in Indianapolis.
