BioHacking with A Continuous Glucose Monitor

A Continuous Glucose Monitor (CGM) is a tiny wearable medical device that accurately measures the amount of sugar (glucose) in your blood 24 hours a day.

These monitors track the user’s blood sugar levels close to real-time without resorting to the standard blood stick test using a glucometer. Please be aware that blood sugar and blood glucose mean the same thing and the terms interchangeably.

Blood glucose is measured in milligrams of glucose per deciliter of blood (mg/dL). Deciliter is 1/10 of a liter.

At first, you may think that Continuous Glucose Monitors (CGM) are only for diabetic or prediabetic (people prone to diabetes) needing better control of their blood sugar. Admittedly that is the target market. And before start-up digital health companies like NutriSense made their appearance, you had to have an “established” medical need and doctor’s prescription. However, that’s changed. CGM’s are increasingly being used in the biohacking community of people without blood sugar issues to improve their health by biohack their blood glucose levels.

What allure does CGM hold for these biohackers? Increased athletic performance, longevity, quicker weight loss, and an increase in energy. Yes…
