https://www.nist.gov/how-do-you-measure-it/how-do-glucose-monitors-measure-sugar-levels-blood Managing blood glucose, also called blood sugar, is a daily challenge for millions of people with diabetes. Small wearable devices called continuous glucose monitors (CGMs) make it easier by helping people track their blood sugar levels throughout the day. To understand how CGMs work, it helps to first start with what happens in your body after you eat. When you eat food, your digestive system breaks it down into nutrients your body can absorb. Carbohydrates, one type of nutrient, are broken down into glucose. When glucose enters your bloodstream, your blood sugar levels rise. https://www.nist.gov/how-do-you-measure-it Much of the world around us would be a mystery without good measurements. Whether it’s the depth of the ocean, the nutrients in your cereal, or the age of dinosaur fossils, measurements enable us to learn about our world and make good decisions about what to do in everyday life. In our “How Do You Measure It?” web series, we answer questions that will help you better understand how our modern world works — and why good measurements play an important role in your life.
