This Week's Blood Glucose Management Summary
Looking back at this week's blood glucose management, I was able to spend a very stable week overall. In particular, my "TIR" (Time in Range), which shows the percentage of time spent within the target range, was well over 70%, and I am delighted to see that my daily efforts are gradually paying off.
On the other hand, there were temporary spikes in blood glucose during the day and late at night, which seemed to be the result of post-meal effects. While the content and timing of my meals might have caused some fluctuations, there were almost no sharp drops (hypoglycemia), and I want to pat myself on the back for managing it safely.
I want to keep this positive momentum going next week as well, aiming for gentle post-meal control while continuing to enjoy my daily care with a positive attitude and at my own pace.
Weekly Trend Analysis
Looking at this week's weekly trend, my average blood glucose level was 153 mg/dL. My "TIR (Time in Range)," which indicates the percentage of time my blood glucose remained within the target range (70 to 180 mg/dL), was 75.9%, successfully clearing the recommended target of 70% or higher.
Additionally, my coefficient of variation (CV), which represents the fluctuation of blood glucose levels, was 27.2%. Since a CV of less than 36% is generally considered a good benchmark, my blood glucose fluctuations this week were very gentle and stable. Please note that comparisons with the previous week and GMI (Glucose Management Indicator)—another important metric—could not be confirmed from the current image. However, overall, I feel it was a highly stable week with few extreme swings toward hyperglycemia or hypoglycemia.
Daily Summary Analysis
Looking at the daily graphs, some different characteristics emerge depending on the day of the week. My best day this week was Wednesday, September 16, when my average blood glucose was kept down to 139 mg/dL, and the maximum value was only 183 mg/dL, meaning I spent almost the entire day within the target range. This might have been because my meals were well-balanced, or because I got a moderate amount of exercise.
On the other hand, there were times when my blood glucose rose significantly, peaking at 273 mg/dL on Thursday, September 17, and 265 mg/dL on Friday, September 18. Since the graph turns yellow around 15:00 on Thursday and into Friday night, it is likely that the menu of my lunch and dinner, or perhaps how fast I ate, temporarily caused larger fluctuations. By keeping these fluctuation patterns in mind, I want to use them to guide my next steps.
AGP Analysis
Let's analyze the AGP (Ambulatory Glucose Profile) graph, which overlays 24-hour blood glucose trend patterns. First, from nighttime to early morning (0:00 to 9:00), the median line (dark blue line) fluctuated between 130 and 160 mg/dL, showing very high stability. This is a great trend that brings peace of mind during sleep.
As a daytime characteristic, we can see that the median rises and the width (variability) of the graph widens around 13:00–15:00 (after lunch) and 21:00–22:00 (after dinner). This indicates that there are daily variations in post-meal blood glucose spikes. The line at the bottom of the graph, which indicates the risk of hypoglycemia, almost never fell below the target value of 70 mg/dL, suggesting that an extremely safe state with a very low risk of hypoglycemia is being maintained.
What Went Well This Week
- Achieved 75.9% Time in Range (TIR): Exceeded the recommended target of 70%, leading to stable management.
- Gentle Blood Glucose Fluctuations (CV of 27.2%): Maintained below the benchmark of 36%, successfully preventing sharp spikes and drops.
- Highly Stable Nighttime Blood Glucose: Blood glucose levels remained steady from bedtime to early morning, allowing for a restful sleep.
- Avoidance of Hypoglycemia Risk: There was virtually no concern about extreme hypoglycemia (under 70 mg/dL) throughout the entire week.
Areas for Improvement for Next Week
- Be Mindful of Gentle Post-Meal Spikes: To curb the rises around 14:00–15:00 and 21:00–22:00, I will try adjusting my eating order and carbohydrate portions.
- Reduce Daily Variability: Since fluctuations tend to increase slightly toward the weekend and the latter half of the week, I will focus on keeping my meal times and daily rhythm as consistent as possible.
- Reflecting on My Best Day: I want to recall my meals and activities on Wednesday—when I was in peak condition with an average of 139 mg/dL—and replicate those good habits.
Summary
Reflecting on this week, seeing my body work hard and the visible results of my daily efforts has been incredibly encouraging. While there are times when my levels are slightly high after meals, overall control is very safe and stable. I feel that the most important thing is not to strive for perfection, but to continue "comfortable management" at my own pace. Let's continue to enjoy delicious food while taking steps toward a healthy daily life next week as well!
