help me understand T2D, I have read the wiki twice
help me understand T2D, I have read the wiki twice. I am not trying to be the "source?" guy. I would just like a source. Postprandial excursions typically respond earlier than fasting glucose, so the sequence people observe is not a sign that something is not working. Sensor accuracy varies across wear, and readings…
The three numbers, and what each one can and cannot tell you.
A1c is an average over about three months, weighted to the recent weeks. It cannot show variability and it lags change. Continuous monitoring shows the shape — excursions, overnight, time in range — and is where improvement usually becomes visible first. Fingersticks are point measurements, useful for sanity-checking a sensor and for specific questions.
Most of the frustrated posts here come from expecting one of the three to answer a question that belongs to another. And all three are inputs to a conversation with whoever manages your care, which is not this board.
That is a sensor value, not a plasma value, and the two are not interchangeable at that level of precision.
What does time in range look like, not just the average?
Have you taken this to whoever manages your diabetes?
Is that a first-day sensor reading?
Small fix — insulin secretion in this class is glucose-dependent, which is precisely why the risk you describe comes from the other agent.
dose for glycaemic control is not the same conversation as dose for weight
