Guides & Tips

Continuous glucose monitoring during pregnancy provides tighter glucose control with less hypoglycemia compared to fingersticks alone. Here is the evidence and practical guidance. Why Tight Control Matters in Pregnancy Hyperglycemia during pregnancy is associated with increased risk of macrosomia, preterm birth, and neonatal hypoglycemia. Targets during pregnancy are significantly tighter than outside pregnancy: typically 63-140 … Read more

CGM alerts save lives. They also cause alert fatigue when misconfigured — leading users to silence alarms that matter. Here is how to set alerts that are actionable without being overwhelming. The Alert Fatigue Problem Studies show that CGM users receive an average of 8-15 alerts per day with default settings. Most people habituate to … Read more

Keeping a CGM sensor stuck for 10-14 days is a challenge for many users — especially those who sweat, swim, or have sensitive skin. Here are the most effective adhesive patches and overlays. Why Sensors Lift Prematurely CGM adhesive is designed for average skin in average conditions. Heavy sweat, frequent showering, body hair, skin conditions, … Read more

Continuous glucose monitors were originally designed for Type 1 diabetes. In 2026, strong evidence supports their use for Type 2 as well — but the benefit varies significantly by treatment type. Here is what the data shows. Who Benefits Most Type 2 on basal-bolus insulin: Strong evidence. CGM significantly reduces A1C and hypoglycemia risk. Most … Read more

Time in Range (TIR) is the most important metric that continuous glucose monitors have added to diabetes management — more actionable than A1C alone. Here is what it means and how to use it. What Is Time in Range? TIR is the percentage of time your glucose spends within your target range, typically 70-180 mg/dL … Read more

At $10-20 per sensor day, losing a sensor early is frustrating. These evidence-based tips extend adhesion and reduce premature failures across Dexcom and FreeStyle Libre. Site Preparation Is Everything Clean skin at the application site is the single biggest factor in sensor longevity. Use an alcohol wipe and let it dry completely — at least … Read more

Exercise affects glucose differently depending on the type, intensity, and your insulin timing. A CGM gives you real-time data to navigate workouts safely — but knowing how to interpret that data is the key. Why Exercise Complicates CGM Readings Physical activity affects CGM accuracy in two ways: sensor placement (arm movement, pressure on adhesive) can … Read more

CGM trend arrows are as important as the glucose number itself. They tell you not just where your glucose is, but where it is going — and how fast. Misreading an arrow can lead to under- or over-treatment. The Five Trend Arrows ↑↑ Double Up: Rising faster than 3 mg/dL/min (>2 mmol/L/min). Glucose rising very … Read more
