Nah, that's not how it works for Type 1. Those cells get wiped out in one massive hit, and then after that, any "new" cells trying to step up to the plate for a little while—which is why people talk about that "honeymoon phase"—might last maybe a year or so, but eventually, they all die off.
People with Type 1 don't usually have high blood sugar if they're managing things right—my own levels stay between 40 and 125 mg/dL every single day because I'm obsessed with what they call "tight control." But honestly? Nothing has regenerated for me, trust me. 😁
What you're talking about is more of a Type 2 thing. With Type 2, the main headache is insulin resistance. The cells are making insulin, sure, but the body can't actually use it effectively—usually because the insulin receptors (those little molecules on the cell membrane that catch the insulin and let it do its job) are basically broken. Because of that inefficiency, you end up with a
relative lack of insulin (whereas Type 1 is an absolute lack). To compensate, the pancreas goes into overdrive—because of that feedback loop—so the higher the sugar climbs, the more the pancreas feels like it needs to crank out more insulin. So, yeah, there's plenty of insulin floating around, but what good is it if it can't do its one job... which is letting glucose move from the blood into the tissue cells to feed them...
The harder the pancreas tries to keep up, the more exhausted and burnt out it gets, until finally, it just can't keep up with the high sugar anymore... and so, on top of the resistance, you end up with failing pancreatic function too.
That’s why Type 2 patients are usually prescribed two different kinds of meds: stuff to lower resistance and stuff to nudge the pancreas along to produce more insulin. And look, the big takeaway for Type 2 is that losing weight is huge—the fewer cells we have (especially fat cells), the less insulin we need, so we don't have to constantly torture the poor pancreas.
Hope that makes sense... 🙂
