They saw this, then tried only one insulin treatment, and it didn’t help, despite reducing blood sugar.
It would seem getting your blood sugar under control on your own, would be best, while healing.
When I had a stroke, my blood sugar skyrocketed. They were giving me insulin - only time in my life I’ve had it. They injected me for about 20 days. This had NOTHING to do with what I was eating.
The 3rd day I was in the hospital the head nutritionist came to my bedside and asked me why I wasn’t eating. I told her she was giving me about 3 times the carbs in ONE meal that I normally eat in 3 days. She asked me what I would eat, I told her eggs and bacon, no toast. Chef’s salad, no dressing unless she had olive oil. Grilled chicken thigh and broccoli. She started sending me meals like that, and I started eating again.
When I researched the “high blood sugar not food related” thing, I discovered that when you have a traumatic injury (a stroke is considered a traumatic injury), your body (picture it like a gyroscope) “wobbles”, trying to regain equilibrium. Your high blood sugar is part of your body trying to return to normal.
