Chatbot coach takes aim at diabetes risk after pregnancy
NCT ID NCT05949957
First seen Sep 15, 2026 · Last updated Sep 16, 2026 · Updated 1 time
Summary
Women who develop gestational diabetes are far more likely than other women to develop type 2 diabetes within a few years after giving birth. This trial tests whether a smartphone app that delivers personalized coaching on diet, exercise, sleep, and mental well-being can help prevent that. Researchers in Singapore are enrolling 400 women aged 21 to 45 who had gestational diabetes in the past one to ten years. Everyone gets a health information app and a ring that tracks activity, sleep, and stress; half also get the coaching app. The team follows participants for four years and measures blood sugar, weight, blood pressure, and other health markers.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- A smartphone chatbot coaching program called LvL UP, paired with a wearable Oura ring and a health information app
- What this could lead to
- If the coaching works, it could give women who had gestational diabetes a low-cost, phone-based way to lower their risk of type 2 diabetes. It could also shape how digital health programs are offered in the community.
- What could go wrong
- App-based coaching depends on people sticking with it for months, and many digital health programs lose users over time. The trial may show that the app does not change blood sugar enough to matter, or that any benefit fades after the coaching stops.
