Medical Xpress / Smartwatch and blood test data combine to better predict insulin resistance and diabetes

Around 20–40% of the general population are estimated to have insulin resistance—a condition where insulin begins to be less effective in the body, and glucose regulation becomes more difficult. Eventually, this can lead ...
