Your blood sugar level, also known as blood glucose level, indicates the amount of glucose present in your bloodstream at a given time. Glucose is a primary source of energy for your body's cells and is derived from the foods you eat. Here’s what different blood sugar levels typically mean:
-
Normal Blood Sugar Levels:
- Fasting (before eating): 70–99 mg/dL
- 2 hours after eating: Less than 140 mg/dL
-
Prediabetes:
- Fasting: 100–125 mg/dL
- 2 hours after eating: 140–199 mg/dL
-
Diabetes:
- Fasting: 126 mg/dL or higher
- 2 hours after eating: 200 mg/dL or higher
Monitoring your blood sugar levels is crucial for managing diabetes or prediabetes. Consistently high levels can lead to complications such as nerve damage, kidney disease, and cardiovascular issues. If you have concerns about your blood sugar levels, consult a healthcare professional for personalized advice.
