Blood Glucose Log - Free Printable PDF for Daily Blood Sugar Tracking

What Does This Blood Glucose Log Track?

This printable log helps people with diabetes record their blood sugar levels in a structured, repeatable way. The form covers multiple reading periods throughout the day and provides space for medication notes and lifestyle observations that support effective diabetes care.

What to Record Each Day

• Blood glucose readings before and after each meal
• Morning fasting and bedtime readings
• Medication names, dosages, and timing
• Food notes and estimated carbohydrate intake
• Physical activity type and duration
• Symptoms, unusual readings, or comments for your care team

Many people with diabetes use the log to detect patterns, such as consistently high post-meal readings or overnight dips. Bringing two to four weeks of completed sheets to an appointment gives your doctor concrete data to fine-tune your treatment plan.

The form is sized to fold and carry in a pocket or purse for on-the-go use. Print several blank copies to keep a supply on hand. The log also includes reminders about immediate steps to take if a reading falls dangerously low. If readings drop below your target range, consume fast-acting carbohydrates right away. If readings stay consistently high, share the log with your care team to adjust your meal plan, activity level, or medication together.

Record a reading after each meal and at bedtime. Many diabetes educators recommend at least four readings per day during active management periods to get a clear picture of daily patterns.
