This Week's Blood Glucose Management Summary
This week, my blood glucose management resulted in an average glucose level of 171 mg/dL and a Time in Range (TIR) of 59.1%. Although I fell slightly short of my 70% target, I can feel my daily efforts gradually paying off.
On a particularly positive note, my coefficient of variation (CV), which indicates blood glucose variability, was 30.7%, successfully staying well below the target of 36% or less. On the other hand, I noticed some temporary spikes in high blood glucose over the weekend and after meals. Instead of striving for perfection, I want to find areas to improve at my own pace. Let's stay positive and enjoy a healthy daily life next week as well!
Weekly Trend Analysis
Let's review the weekly trends showing the overall patterns of this week. My average blood glucose was 171 mg/dL, and my Time in Range (TIR), which shows the time spent within the target range (70–180 mg/dL), was 59.1%. Although there are occasional signs of high blood glucose exceeding 250 mg/dL (red plots), overall, I managed to keep my levels within the green target range for much of the time.
Note that comparative data with the previous week and GMI (Glucose Management Indicator), a key marker in diabetes management, could not be confirmed from this image. Even so, the fact that my CV (coefficient of variation), which indicates the smoothness of glucose fluctuations, met the stability standard at 30.7% is proof that my daily efforts are translating into positive changes.
Daily Summary Analysis
Looking at the detailed daily data, we can infer how differences in daily routines depending on the day of the week affect blood glucose levels. The best control this week was on Friday (September 4), with an average blood glucose of 133 mg/dL and a peak of only 201 mg/dL, making for a very stable day. It seems that the regular rhythm of weekdays had a positive impact.
On the other hand, on Sunday (August 30), the average blood glucose was relatively high at 202 mg/dL, with a peak of 323 mg/dL. On Saturday (September 5), there was also a spike up to 302 mg/dL and a mild tendency toward hypoglycemia, reaching a low of 66 mg/dL around 15:00. It is likely that the relaxed meals and changes in physical activity over the weekend led to these ups and downs in my blood glucose levels.
AGP Analysis
Let's analyze the AGP (Ambulatory Glucose Profile), which overlays 24-hour glucose variability patterns. First, overnight glucose levels (0:00 to 6:00) remained relatively stable between 130 and 180 mg/dL, though they were generally on the higher side, close to the target baseline (the green line at 180 mg/dL).
A key characteristic during the day is the postprandial spike trend, where the median (dark blue line) exceeds the target of 180 mg/dL during three specific time frames: after breakfast (around 10:00), after lunch (around 14:00), and after dinner (around 21:00). Especially from afternoon to night, the gray band (95% range) representing data variability widens significantly, suggesting that blood glucose movements vary greatly depending on that day's meals and physical activity.
Key Successes This Week
- The coefficient of variation (CV), which indicates the degree of blood glucose variability, was 30.7%, successfully staying below the standard threshold of 36%.
- On Friday (September 4), I maintained a highly stable and ideal trend throughout the day with an average of 133 mg/dL.
- My TIR (Time in Range) reached 59.1%, giving me a real sense of moving step-by-step toward my 70% goal.
Areas for Improvement Next Week
- Since my blood glucose tends to run high on weekends like Saturday and Sunday, I will be more mindful of meal choices and the eating order on my days off.
- To mitigate blood glucose spikes after each meal (around 10:00, 14:00, and 21:00), I will practice "vegetable first" by starting meals with options like vegetable soup.
- As temporary hypoglycemia (66 mg/dL) was observed on Saturday evening, I will consider preventive measures, such as having a snack earlier to match my afternoon activity levels.
Conclusion
Through this review, I have gained a clear understanding of the differences in how I spend my weekdays versus weekends, as well as the characteristics of postprandial spikes. Visualizing my body's signals helps me come up with positive ideas like, "Let's try this next." Without overthinking it too much, I want to keep managing my health comfortably at my own pace next week!
