There are many seniors and people on SSD on Medicare with Insulin Dependent Diabetes. Some of us have severe issues with low blood sugars. These include unawareness of lows, passing out, losing entire days to insulin shock and seizures, in some cases with TIA(mini-strokes). All of the above for myself but a CGM sounds an alarm when the blood sugar begins to drop, potentially avoiding these episodes, which can result in full strokes and death. Private insurance and Medicaid will cover them, Medicare should as well.
