For diabetes patients, treatment is not easy. Diabetes requires diligent, ongoing monitoring and maintenance to maintain stable blood sugar levels. This is can be difficult to do as most diabetics manage this with manual insulin injection and blood glucose monitoring (BGM) by sampling blood at their fingertips several times a day. Blood sugar levels can vary wildly through the day depending on food consumption, timing, and exercise. Even if a patient samples their blood sugars up to eight times through the day, there is still room for dangerous fluctuations between measurements which the patient may be unaware of. These fluctuations can exacerbate acute or chronic complications of diabetes, many of which are life-threatening.
This is where a Continuous Glucose Monitor (CGM) comes in: it samples the blood sugar much more often throughout the 24-hour day, sometimes as often as once per minute. This enables the patient to respond with insulin therapy much more effectively to maintain consistent blood sugar levels. In the long term, this can prevent many health complications which are associated with diabetes, such as blindness.
Type 1 diabetes often strikes children. My brother was 10 when he was diagnosed. At that age, children don’t usually appreciate the long-term value of careful treatment and they are often not careful enough to consistently self-administer therapy reliably. A CGM can help a young patient by being an active partner in the ongoing blood sugar monitoring process, alerting him or her in case intervention is needed. In addition, a CGM can provide parents or doctors with the same blood sugar measurements so they can intervene and manage therapy as needed until the patient is old enough to take responsibility for themselves. One family’s story of how CGM saved their daughter’s life can be found here.
CGMs have been around for years, but they have traditionally been larger belt-worn devices. I can imagine how inconvenient this would be for sleeping, playing sports, and other normal daily activities. With the miniaturization and small batteries that ON Semiconductor enables in our low-power designs, it is now possible to wear a CGM in a small body-worn patch. The patch can wirelessly transmit blood sugar levels to a receiver. Often this is paired with an automated insulin pump for even better therapy.
Modern wearable electronics bring convenience to modern medical therapy by making electronics smaller and as minimally evasive as possible. This will increase adoption and the quality of life for millions of patients.
