Understanding & Managing Blood Sugar

Blood sugar shows up in headlines constantly, but most people never learn the actual mechanics of how their body keeps it in balance — or what changes when that system breaks down. This course builds that foundation from the ground up: how insulin and glucagon work together like a thermostat, what's conceptually different between type 1 diabetes, type 2 diabetes, and prediabetes, and why the distinction matters for how each is approached.

From there, the course moves into the levers you actually control day to day — how different foods affect blood sugar and why fiber and protein change the picture, how a single bout of exercise can improve insulin sensitivity for up to 24-48 hours, and why sleep and stress are just as metabolically relevant as diet. The final lessons cover recognizing warning signs worth taking seriously, understanding (at a conceptual level) what home monitoring numbers and A1C represent, and building small, sustainable daily habits instead of chasing short-term fixes.

This course explains mechanisms and general lifestyle patterns — it does not replace personalized care. Every lesson closes with a flashcard set and a Quick Check quiz, and a final exam ties the whole course together.

This course is for educational purposes only and is not medical advice. Diabetes and blood sugar management require personalized guidance from a qualified healthcare provider — always consult one before making changes to diet, exercise, or medication, and before interpreting any personal blood sugar readings.
