Why do I not feel when my blood sugar is low I fuction at 35 just as I would 90 and is there anything I can do?

Have less lows. I assume u have diabetes & r on meds. When patients have frequent low sugars, they stop getting warning signs - palpitations, sweating, tremors- &don't have symptoms until their sugar is dangerously low, then get confused and pass out. By letting the sugars run a little high for a while, the hypoglycemic awareness comes back. Also consider a continuous glucose sensor. Make sure ur meter is right.
