Last night was an epic battle against hypoglycemia, with my Apple Watch alerts constantly waking me up. I managed to bounce back thanks to the 'Morinaga Ramune' I keep by my bed, but the graph's distinct peaks and valleys vividly show just how directly its main ingredient – glucose – impacted my system.

【Summary: My Late-Night Glucose Combat Log】

  • Each time the alert screamed, I popped 8, then 5, then another 8 pieces of Ramune (90% glucose), just barely making it through the night.
  • While the immediate impact of glucose was undeniable, the data clearly illustrated its downside: 'rapid absorption equals short-lived effects.'
  • The rollercoaster-like pattern on the graph vividly highlights the 'snack struggle' – how my blood sugar would shoot up from a low, only to plummet back down again.

【Ramune (90% Dextrose): Ingredient Analysis & Graph Correlation】

  • The Ramune I consumed is made up of 90% 'hydrous crystalline glucose' (dextrose).

  • As a monosaccharide, glucose requires virtually no digestion or absorption process. It quickly enters the bloodstream directly from the small intestine after consumption, possessing the incredibly powerful ability to spike blood sugar levels through the fastest possible route.
  • The sharp, mountainous peaks visible on the graph, including the 'Δ+20 (Peak),' are a direct consequence of this high-purity glucose flooding my bloodstream. Its rapid effectiveness is nothing short of a 'wonder drug.'

  • However, as this data clearly shows, the phenomenon of my blood sugar plummeting again shortly after consumption, triggering yet another alert, is likely due to glucose's rapid absorption meaning its effects wear off just as fast. This characteristic perfectly intertwined with my nighttime blood sugar patterns.
  • The varying intake of 8, 5, and 8 pieces reflects my panic and the perceived blood sugar recovery at those moments. Yet, observing the graph's patterns, I deeply regret that I should have exercised more careful, situation-specific control, rather than creating dramatic spikes with large, sudden doses.
  • What caused this particular episode of hypoglycemia? Was it my first run and strength training session in a while? Still unclear???
  • Kudos to my Libre 2 and Apple Watch for their excellent low blood sugar alerts, by the way!

Type 1 Diabetes: My Wild Blood Sugar Rollercoaster After a 5-Hour Walk and Sweet Treat!

Hello everyone! Today, I'm reporting on a day of intense blood sugar fluctuations, as recorded on my CGM (Continuous Glucose Monitor) graph.

I'll be looking back at a day where a moment of complacency – thinking 'I walked a lot, so I'll be fine!' – combined with insulin timing and the actual meal choices, spectacularly led to a severe blood sugar spike followed by a roller-coaster ride.

A Day's Blood Sugar Graph (CGM Data)

(CGM graph showing a rapid climb to nearly 300 mg/dL after 14:00 and a sharp drop to around 60 mg/dL around 22:00)

Timeline of Activities, Meals, and Insulin on This Day

  • 10:00 AM ~ 3:00 PM Long walk in the Omotesando-Roppongi area (a solid 5 hours of walking)
  • Around 12:00 PM (Lunch) Udon + Shirasu-don at Udon Shiki Roppongi Before meal: Humalog 12 units
  • 3:00 PM (Snack) "Kürtősh" + Coffee at Balaton Cafe Omotesando
  • Around 9:00 PM (Dinner) Low-carb meal (hot pot vegetables and pork) Before meal: Humalog 12 units + Tresiba 7 units
  • Around 10:00 PM Blood sugar plummeted to around 60 mg/dL (entering hypoglycemic range)
  • 10:30 PM (Correction Snack) Consumed Ramune, half a Dekopon orange, and 2 strawberries ➔ Successfully recovered afterwards

What Happened? Analyzing the Blood Sugar Rollercoaster Mechanism

Cause ①: The Rocket Surge between 3:00 PM and 4:00 PM

The 5-hour walk depleted my body's sugar energy, leaving my cells in a 'starved state,' intensely craving glucose. Into this state, I rapidly consumed a 'Kürtősh' — packed with sugar and flour, and incredibly fast-absorbing — which caused a ferocious blood sugar spike, shooting up to nearly 300 mg/dL.

Cause ②: The Plunge to the Abyss around 10:00 PM

I administered insulin before dinner, but the side dish was a 'hot pot' – an extremely low-carb meal. This meant there wasn't enough carbohydrate to counteract the insulin. Furthermore, the residual effect of the 5-hour walk made the insulin several times more effective than usual, causing my blood sugar to plummet abruptly to 60 mg/dL.

The Divine Relay: "Ramune + Half a Dekopon ➔ 2 Strawberries"

As my blood sugar dropped to around 60 mg/dL and symptoms appeared, I used fast-acting Ramune (glucose) for an emergency rescue. Afterwards, to prevent a 'second dip' from lingering insulin effects, I sustained sugar absorption gradually with the water and fiber from the fruits. My blood sugar then maintained a nice flat line around 80-90 mg/dL!

Future Strategies and Lessons Learned (Summary)

  • Avoid the 'first bite' of sweets after prolonged exercise: Have coffee as a latte, or eat some nuts or protein before indulging in Kürtősh.
  • Balance dinner menu and insulin on exercise days: If cutting carbs and only eating hot pot, reduce insulin units after consulting your doctor. Alternatively, since it's after exercise, intentionally eat a moderate amount of rice to balance it out.
  • Share data with your doctor: Discuss this valuable pattern data – 'long exercise + no-carb dinner + usual insulin dose = hypoglycemia' – at your next appointment.

About the Shop and 'Kürtősh'

💡 Many people might not know? What is 'Kürtősh,' a traditional Hungarian sweet?

The 3 PM snack I had at Balaton Cafe in Omotesando was 'Kürtősh,' a traditional Hungarian pastry. It's a unique sweet, characterized by its chimney-like shape, made by wrapping dough strings around a cylinder and baking it.
The freshly baked surface, generously coated with sugar and cinnamon, is absolutely delicious. However, its main components – flour, butter, and plenty of sugar – make it extremely high in carbohydrates, giving it the characteristic of dramatically spiking blood sugar when eaten alone.

Hello everyone! Today, I'm reporting on a day of intense blood sugar fluctuations, as captured by my CGM (Continuous Glucose Monitor) graph.

I'll look back at a day where my overconfidence of "I walked a lot, so I'll be fine!", combined with insulin timing and the actual meal choices, intricately conspired to create a spectacular blood sugar spike followed by a true blood sugar rollercoaster.

Blood Sugar Graph (CGM Data) from a Specific Day

(Graph image showing a sharp rise to nearly 300 mg/dL after 14:00, then a rapid drop to around 60 mg/dL around 22:00)

Timeline of Actions, Meals, and Insulin on This Day

  • 10:00 〜 15:00 Long walk through Omotesando ~ Roppongi area (a solid 5 hours of walking)
  • Around 12:00 (Lunch) Udon + Shirasu Don (Whitebait Bowl) at Udon Shiki Roppongi Pre-meal: Humalog 12 units
  • 15:00 (Snack) Kurtosh + Coffee at Balaton Cafe in Omotesando
  • Around 21:00 (Dinner) Low-carb meal (hot pot vegetables and pork) Pre-meal: Humalog 12 units + Tresiba 7 units
  • Around 22:00 Blood sugar plummeted to around 60 mg/dL (entering the hypoglycemia zone)
  • 22:30 (Rescue Snack) Consumed Ramune, half a Dekopon (tangerine), and 2 strawberries ➔ Successfully recovered afterwards

Why Did It Happen? Analyzing the Blood Sugar Rollercoaster Mechanism

Cause ①: Rocketing Spike from 15:00 to 16:00

The 5-hour walk depleted my body's glucose energy, leaving my cells in a "starved state" craving sugar. Pouring in "Kurtosh" – packed with sugar and flour, and absorbed at an ultra-fast pace – caused a furious blood sugar spike, shooting up to nearly 300 mg/dL.

Cause ②: Plunge to the Abyss Around 22:00

I injected insulin before dinner, but since the side dish was a "hot pot" – an extremely low-carb meal – there was a critical lack of carbs to offset the insulin. Furthermore, the delayed effect of the 5-hour walk made the insulin several times more potent than usual, leading to a sudden drop to 60 mg/dL.

A Fine Play Against Hypoglycemia: My Rescue Snack Choices This Time

The Divine Relay: Ramune + Half Dekopon ➔ 2 Strawberries

As my blood sugar dropped to around 60 mg/dL and symptoms appeared, I initiated an emergency rescue with fast-acting Ramune (glucose tablets). Afterward, to prevent a "second dip" from the lingering insulin effect, I used the water and fiber from fruits to sustain a gradual sugar absorption. After the rescue snacks, my blood sugar nicely maintained a flat line around 80-90 mg/dL!

Future Strategies and Lessons Learned (Summary)

  • Avoid the "first bite" of sweets after prolonged exercise: Have coffee as a latte, or eat some nuts or protein before the Kurtosh.
  • Balance dinner menu and insulin on exercise days: If cutting carbs and only eating hot pot, discuss with your doctor to reduce insulin units. Alternatively, since it's after exercise, intentionally eat a moderate amount of rice to balance it out.
  • Share data with your doctor: Discuss this valuable pattern data – "prolonged exercise + no-carb dinner + usual insulin units = hypoglycemia" – at your next appointment.
