Why Consistency in Blood Glucose Logging Matters
Blood sugar levels fluctuate constantly based on what you eat, physical activity, medication timing, stress, and illness. Logging your levels alongside the timing (e.g., fasting vs. after a meal) helps your clinician identify glucose patterns and determine if adjustments to your diet or care plan are warranted.
Understanding Target Ranges
For adults with diabetes, typical target ranges are 80-130 mg/dL (4.4-7.2 mmol/L) fasting, and under 180 mg/dL (10.0 mmol/L) 1-2 hours after a meal. Targets should always be personalized by your healthcare provider, taking age, lifestyle, and other conditions into account.
Avoiding Common Glucose Testing Mistakes
Wash and thoroughly dry your hands before testing. Food residue on fingers can cause falsely elevated readings. Ensure test strips are not expired and are stored in their original container away from heat or humidity.
When to Seek Urgent Medical Attention
- Extremely low blood sugar (below 70 mg/dL / 3.9 mmol/L) accompanied by severe confusion, shaking, or inability to swallow.
- Extremely high blood sugar (above 250 mg/dL / 13.9 mmol/L) accompanied by rapid breathing, nausea, extreme thirst, or fruity-smelling breath (signs of Diabetic Ketoacidosis).
Frequently Asked Questions
For individuals without diabetes, fasting levels are normally under 100 mg/dL (5.6 mmol/L). Consistent fasting values between 100 and 125 mg/dL suggest prediabetes.
Levels below 70 mg/dL (3.9 mmol/L) can cause shakiness, sweating, rapid heart rate, confusion, double vision, or loss of consciousness.
