This Week's Blood Glucose Management Summary
Looking back at this week's blood glucose management, it was a highly educational week with circumstances changing significantly between the first and second halves of the week. During the first half of the week, my blood glucose levels tended to run high overall, and I sometimes felt a bit sluggish. However, during the second half of the week, on Thursday and Friday, I was able to keep them firmly within the target range, and I felt very light and active. Being able to regain control on my own midway through the week has given me a great boost of confidence.
A particularly positive point was that my blood glucose levels were extremely stable over Thursday and Friday, maintaining an excellent daytime average in the 130 mg/dL range. On the other hand, there was a tendency for blood glucose levels to run high from late night to early morning, so I feel that this nighttime control is an area for future improvement. Next week, I want to work positively toward extending the good condition from the latter half of the week to the entire week!
Weekly Trend Analysis
Analyzing the weekly trend report, the average blood glucose level for this entire week was 204 mg/dL, and the Time in Range (TIR: the percentage of time spent within the target blood glucose range) was 45.4%. In addition, the Coefficient of Variation (CV), which indicates the degree of blood glucose fluctuation, was 38.0%, slightly exceeding the target of 36% or less, suggesting that the daily fluctuations in blood glucose levels were somewhat large. While there was generally a lot of time spent in a high blood glucose state, the risk of hypoglycemia was kept extremely low.
Please note that a detailed numerical comparison with the previous week's data could not be confirmed from this image. However, looking at the visual transition of the entire graph, it is clear that after the large fluctuations at the beginning of the week (recording a peak of 394 mg/dL on Wednesday), the levels settled dramatically into the green zone indicating the target range from Thursday onward, transitioning into a stable state. I want to be mindful of maintaining this positive change seen in the latter half starting from the beginning of next week.
Daily Summary Analysis
Looking at the detailed daily movements, there were significant differences in the state of control depending on the day of the week. Thursday (average blood glucose 131 mg/dL, range 72–190 mg/dL) and Friday (average blood glucose 135 mg/dL, range 77–208 mg/dL) were particularly outstanding. On these two days, blood glucose levels remained beautifully within the target range (70–180 mg/dL) throughout the entire day. It is thought that successful food choices and lifestyle habits, such as moving frequently during the day, had a positive impact on these days.
On the other hand, the days with large blood glucose fluctuations were Tuesday (average blood glucose 262 mg/dL) and Wednesday (average blood glucose 278 mg/dL). Late Wednesday night, there was a point where it temporarily rose to 394 mg/dL. On Saturday (average blood glucose 206 mg/dL), high blood glucose exceeding 300 mg/dL was also observed from late night to early morning, which suggests that factors such as meal content, sleep quality, and dinner timing may have had an effect. Using the lifestyle patterns of the good days as a clue, I hope to reduce the number of highly fluctuating days.
AGP Analysis
I analyzed the average 24-hour blood glucose trend using the AGP (Ambulatory Glucose Profile). Looking at the movement of the 50% value (median value) shown by the dark blue line, blood glucose levels remain at a high level of 200–270 mg/dL from late night to early morning (around 00:00 to 06:00), indicating a trend with challenges in nighttime blood glucose stability. During the day, temporary drops are observed around noon (around 12:00 to 13:00) and in the evening (around 18:00 to 20:00), but after those, peaks likely representing postprandial rises (especially in the afternoon around 14:00 to 16:00, and after 21:00 at night) can be confirmed.
Focusing on the evaluation of the fluctuation range (the width of the light blue shaded area), the range is extremely wide, especially from late night to morning, showing that there is a large variation in starting blood glucose levels depending on the day. Fortunately, the risk of falling below the green line indicating hypoglycemia (less than 70 mg/dL) is extremely low. However, because there is exposure to high blood glucose risk (over 180 mg/dL) during many daytime hours, an approach to moderate the daytime postprandial rise and gradually lower the nighttime baseline is considered effective for the future.
Highlights of This Week
- Over the two days of Thursday and Friday, I kept the average blood glucose level in the 130 mg/dL range, achieving highly stable control.
- Throughout the week, the occurrence of hypoglycemia (less than 70 mg/dL) was kept to a minimum (the lowest value being 72 mg/dL on Thursday), allowing me to spend the week safely.
- I did not turn a blind eye to the high blood glucose state in the first half of the week and successfully got my blood glucose levels back on track for the second half of the week.
Areas for Improvement for Next Week
- Although overall evaluation metrics such as GMI (Glucose Management Indicator) could not be confirmed from this image, I will firmly continue measuring and raise my awareness of overall indicators.
- To mitigate the rise in blood glucose from nighttime to early morning, I will review the amount of carbohydrates at dinner and ensure there is ample time between dinner and going to bed.
- To prevent the rapid post-lunch blood glucose rise seen around 14:00 to 16:00, I will adopt the practice of eating order (vegetables first) during meals and incorporate light walking after meals.
- To bring the blood glucose Coefficient of Variation (CV) closer to the target of 36% or less, I will minimize daily variations in food intake and activity levels as much as possible to establish a steady daily routine.
Summary
Through this week's reflection, I have gradually organized my own blood glucose habits and the lifestyle patterns when I achieve good control. Being able to have wonderful days like Thursday and Friday is a really big confidence booster and motivation for me. Without demanding perfection, and while focusing on what I have accomplished, let's take it one step at a time next week as well, enjoying the process of building healthy days!
