A blood sugar of 535 mg/dL is dangerously high and considered a medical emergency. This could lead to a diabetic coma or other serious complications and needs immediate attention.
A normal blood sugar (glucose) level depends on when you last ate. Here are general guidelines:
For someone without diabetes:
* Fasting (no food for 8 hours): 70–99 mg/dL
* 2 hours after eating: Less than 140 mg/dL
For someone with diabetes:
* Fasting: 80–130 mg/dL
* 2 hours after eating: Less than 180 mg/dL
