Understanding Blood Sugar Levels

Normal fasting blood glucose for non-diabetics is less than 100 mg/dL (5.6 mmol/L). Two hours after eating, normal glucose should be less than 140 mg/dL (7.8 mmol/L). For people with diabetes, target ranges vary based on individual treatment plans and should be discussed with a healthcare provider.

Hypoglycemia and Hyperglycemia

Hypoglycemia (low blood sugar, typically below 70 mg/dL) can cause shakiness, sweating, confusion, and increased heart rate. Hyperglycemia (high blood sugar, typically above 180 mg/dL) can cause excessive thirst, fatigue, blurred vision, and headaches. Both conditions require appropriate management and should be discussed with your healthcare provider.

Tips for Effective Tracking

  • Log readings consistently at the same times each day
  • Record meal times to identify food-related patterns
  • Note exercise, stress, and sleep to understand their effects
  • Review patterns weekly to identify trends
  • Share your logs with your healthcare provider
