A bad glucose level depends on whether you are fasting or have recently eaten, and whether you have diabetes or not. Here are general guidelines:
-
Fasting Blood Sugar (before eating):
- Normal: Less than 100 mg/dL
- Prediabetes: 100–125 mg/dL
- Diabetes: 126 mg/dL or higher
-
Postprandial (2 hours after eating):
- Normal: Less than 140 mg/dL
- Prediabetes: 140–199 mg/dL
- Diabetes: 200 mg/dL or higher
-
Random Blood Sugar:
- Diabetes is typically diagnosed if levels are 200 mg/dL or higher, regardless of when you last ate.
For people with diabetes, target levels may vary, but generally:
- Fasting/Before Meals: 80–130 mg/dL
- 1–2 Hours After Meals: Less than 180 mg/dL
Consistently high glucose levels can lead to complications like nerve damage, kidney disease, and cardiovascular issues. Always consult your healthcare provider for personalized targets.
