Weekly Blood Sugar Management Summary
Looking back at this week's blood sugar management, the overall Time in Range (TIR)—which shows the percentage of time spent within the target range—was 54.4%, making it a week where periods of slightly high blood sugar stood out. While the day-to-day variability was a bit concerning, it was a good opportunity to understand my daily life patterns.
The best part was that I was able to manage safely without experiencing any severe hypoglycemia. Next week, I plan to make some adjustments to the timing and content of my meals to keep my blood sugar fluctuations more stable.
Weekly Trend Analysis
The average blood sugar level this week was 174 mg/dL, and the TIR (Time in Range, the percentage of time spent within the target range of 70 to 180 mg/dL) was 54.4%. The Coefficient of Variation (CV), which indicates blood sugar variability, was 36.5%, showing a trend toward slightly higher fluctuations. Note that data regarding GMI (estimated HbA1c) and comparisons with the previous week could not be confirmed from the image.
Regarding the tendency for high blood sugar, there was a period on Tuesday at 16:30 where it temporarily peaked at 383 mg/dL. On the other hand, hypoglycemia was limited to a temporary low of 68 mg/dL early Thursday morning, and it was great that dangerous hypoglycemia was successfully avoided.
Daily Summary Analysis
Looking at the daily changes, Wednesday (average 135 mg/dL) and Thursday (average 136 mg/dL) were very calm, making for two highly stable and ideal days. It seems that the balance between meals and physical activity aligned well on these days.
On the other hand, glucose levels trended higher overall toward the weekend, averaging 222 mg/dL on Friday and 192 mg/dL on Saturday. This may have been influenced by meal choices in a relaxed weekend atmosphere and changes in activity levels.
AGP Analysis
Looking at the AGP (Ambulatory Glucose Profile), which shows the average 24-hour glucose trend, levels were relatively stable between 120 to 150 mg/dL during the night (around 00:00 to 03:00). However, there is a trend where blood sugar gradually rises from 03:00 onward into the morning.
Additionally, during the day, the rise in blood sugar is particularly noticeable towards the evening (around 16:00 to 18:00). In individual data, this period shows a spread reaching up to nearly 350 mg/dL, suggesting a hidden risk of hyperglycemia. This could be influenced by the choice and timing of snacks, or the level of activity before dinner.
Key Successes of the Week
- Maintained average glucose levels in the 130 mg/dL range on Wednesday and Thursday, achieving highly stable control.
- Blood sugar levels during the night (around 00:00 to 03:00) trended relatively calmly and stably.
- Although there was a temporary drop (68 mg/dL) early Thursday morning, prolonged hypoglycemia was avoided, allowing for a safe week.
Areas for Improvement for Next Week
- Try adjusting the choice and timing of afternoon snacks to smooth out the rapid spike in blood sugar during the evening (around 16:00 to 18:00).
- Pay attention to the balance of meal portions and physical activity on days off to prevent high blood sugar over the weekend (Friday and Saturday).
- Consider the connection between dinner timing or the sleep environment and the trend of rising blood sugar from dawn (after 03:00) onward.
Summary
Although there were days with slightly higher readings this week, there were also days when I managed stably, making it a fruitful week where I could clearly see the habits of my blood sugar fluctuations. Let's continue comfortable and healthy lifestyle habits at our own pace, step by step, without rushing, next week as well!
