Skin Sensor Cut Blood Sugar and Prevented Dangerous Lows in Type 1 Diabetes

Adults with type 1 diabetes whose blood sugar was hard to control wore a sensor that scans glucose levels throughout the day. After six months, their average blood sugar dropped significantly and they spent 43 fewer minutes per day in dangerous low-sugar territory compared to traditional fingerstick testing.

What the trial was testing

The FLASH-UK enrolled 156 patients with type 1 diabetes. The study was sponsored by Manchester University NHS Foundation Trust and tracked outcomes across the full group of patients who matched the trial's eligibility profile.

Researchers followed patients through treatment and into recovery, tracking the outcomes that mattered most for the disease being studied.

What the results showed

The sensor group spent 130 more minutes per day in healthy blood sugar range.

These findings — that time spent in healthy blood sugar range vs. fingerstick testing — were published in the The New England journal of medicine and represent the headline result of the study.

Researchers tracked outcomes across 156 patients enrolled in the trial. The result was consistent enough across the group that the team felt confident reporting it.

What this means for patients

For patients with type 1 diabetes, this result changes the calculus on what to ask their care team about. Whether it changes day-to-day care depends on factors like disease subtype, prior treatments, and where the patient is in their care journey.

What you can do now

If your type 1 diabetes is hard to control with fingerstick testing, this sensor technology is FDA-approved and available now. It scans your glucose levels continuously and can alert you when you're going too high or too low. Talk to your doctor about whether continuous glucose monitoring is right for you.

Eligibility for the treatments mentioned above depends on specific test results and clinical history. Bring this summary, the trial name, and your most recent labs or pathology report to your next visit.
