Shining a light onto the skin could become a new test to see if people are in the earliest stages of diabetes and heart disease.
The approach may offer a way of screening people for these health conditions that’s quicker and easier than current methods that include blood tests, and assessing risk factors such as people’s weight and family history.
The method works because glucose in blood and other bodily fluids can randomly stick to many different protein molecules in skin and other tissues. “It’s like glue,” says Bruce Wolffenbuttel of the University of Groningen in the Netherlands.
These “glycated” proteins, known as advanced glycation end products, or AGEs, make for stiffer tissues, including blood vessel walls, which contributes to high blood pressure.
