@A DiabetesTeam Member yes there is Continuous Glucose Monitor Sensors that are read by Android Smart Phones

There is no requirement for "how many tests" before a Doctor will write a prescription for them BUT depending on your own Insurance coverage will be determined by them

I take NO Meds and my insurance pays for it (15% deductable) - other carriers only pay if you are using Insulin or taking Sulfonylurea class drugs - so coverage varies widely

But if you qualify the most popular systems are Freestyle Libre 2 or 3 and Dexcom 6 or 7

@A DiabetesTeam Member. Hi Kat
Sorry for your dental loss. Sounds horrid. Same thing happened to my mom. All though I have not heard of it from any other diabetic. I hope and pray things get resolved for you soon. Neurapathy no matter were it gets us is a bad bad effect of being diabetic. I have hair loss from it!

The relationship between caffeine and A1C levels can vary from person to person. If you have diabetes, caffeine may cause short-term blood sugar fluctuations. It's important to monitor your blood sugar levels when consuming caffeinated beverages to understand how your body responds.

The relationship between caffeine and A1C levels can vary from person to person. If you have diabetes, caffeine may cause short-term blood sugar fluctuations. It's important to monitor your blood sugar levels when consuming caffeinated beverages to understand how your body responds.

If you notice jittery feelings or higher blood sugar after drinking regular coffee, switching to decaf might help stabilize your levels. When making changes to your caffeine intake, it's recommended to do so gradually rather than suddenly. This allows you to better monitor any effects on your blood sugar. Many of coffee's beneficial effects can still be obtained from decaf varieties.

Track any changes in your blood sugar levels and share this information with your healthcare provider to develop the best plan for managing your diabetes.

I was very surprised when Kevin Costner stood at the open window of the car and said “stick em up”.
I thought that only happened in cowboy movies 🤣
