New Tool for Kids: FDA Approves Over-the-Counter Glucose Monitor
The FDA recently approved Dexcom’s Stelo Glucose Biosensor System as the first over-the-counter (OTC) continuous glucose monitor (CGM) for children. Now, children aged 2 and older can use it without a prescription, although adult supervision is needed. This device was previously approved for adults in 2024. Its availability may help families better understand and manage blood sugar levels, especially as prediabetes among children becomes more common. This step shows progress in making health tools accessible and easy to use for young people.
How It Works and Its Impact
Stelo uses a small sensor worn on the body that measures glucose levels every 15 minutes. The sensor pairs with a smartphone app, making it simple to track blood sugar over time. Each sensor lasts up to 15 days, but in children, its wear time might be shorter due to various factors. The goal is to increase awareness of blood sugar’s connection to diet and exercise, potentially helping prevent Type 2 diabetes. While this device is a step forward scientifically, caregivers should always consult a doctor before making health decisions based on its readings.
Balanced Perspective on Use and Precautions
Despite its benefits, Stelo isn’t for everyone. It can’t alert users if blood sugar drops dangerously low, so people on insulin, with dialysis, or with disordered eating should avoid it without doctor guidance. Also, some mild side effects, like skin irritation or discomfort, were reported in previous studies. Experts advise consulting a doctor before using OTC CGMs, especially for children or those with prediabetes. While the device offers promising advancements, careful use and professional advice remain essential for safe, effective management.
