Testing a swallowable camera to screen for stomach disease in older adults

This trial is testing a new screening method using a small, swallowable capsule camera (called magnetically controlled capsule gastroscopy) to detect stomach diseases early. Unlike traditional endoscopy, which requires a tube inserted down your throat, this capsule is easier to swallow and doesn't require sedation. The study will enroll 10,000 older adults and high-risk people in China to see how well this technology can find stomach problems before they become serious.

Stomach diseases like ulcers, inflammation, and cancer are very common and often detected too late, when they're harder to treat. Traditional stomach screening is uncomfortable, invasive, and not widely available in many communities, which means many people don't get screened. This study is testing whether the swallowable camera can make screening easier, more comfortable, and available to more people.
