Swallowable sensor to measure gut health in colon disease

Researchers are testing a small, swallowable sensor device that measures oxidation-reduction potential — essentially a marker of chemical stress — directly in your colon. The study includes people with ulcerative colitis (a type of inflammatory bowel disease) and people with colorectal cancer. The goal is to see whether this sensor can detect disease activity before and after treatment, offering a less invasive alternative to traditional endoscopy.

Current methods to diagnose colon inflammation and cancer require uncomfortable endoscopy procedures. Researchers believe that measuring oxidative stress in the gut could become a simpler, less burdensome way to monitor disease and screen for cancer. This sensor technology might one day help doctors personalize treatment and improve cancer screening programs.
