Your Best T1D Year

The After-Dinner Blood Sugar Spike, Explained | T1D Pre-Bolus Challenge


Listen Later

SHOW NOTES: You counted the carbs. You took the right dose. Two hours later you’re 240, and you have no idea why. If that number breaks your heart a little, this episode is for you. Neil sits in the problem of the post-meal spike, the one that feels like a personal failing but almost never is.

This is the roller coaster every person with type 1 diabetes knows: spike, correct, drift low, snack, climb again, and it’s 9pm and you’re stacking insulin and snacks in the dark. Neil makes the case that this whole loop usually traces back to one thing, the food got a head start and your insulin spent the first hour catching up. It’s not your discipline. It’s your timing. And timing is the most fixable variable in type 1.

In this episode:

  • Why the after-dinner spike feels like your fault but usually isn’t

  • The correction-and-crash loop that wrecks your evening

  • Why the timing of your dinner bolus is the most fixable variable in T1D

  • What this challenge is really trying to give you back

This Week’s Challenge: Keep noticing your blood sugar two hours after dinner. Peek at your number right before you eat, too. Two snapshots. Change nothing yet.
