I am type 2 (some say type 3) from severe pancreatitis. First acute, then chronic for the past 40+ years.
They told me that I would end up diabetic, and I held it off until around 40 years old. At that point my sugar was 580 and I honestly don't know what my A1C was. I was sick.
Started on regular metformin and that was good until around 60 years old. Then I needed to add Glipizide. Fine until 65.
Now I am on Lantus and Humalog insulins and Metformin ER and Glipizide. I can not take the Ozempic type of insulins (even if I could afford them, which I cannot), because of my damaged pancreas. Plus I already have motility issues with my digestion, I don't need more..
My last year of A1C has been 7.5 and my sugar is normally 145 or so. It does bounce around depending on what I eat, and when I have taken my meds. I do still cheat here and there, but with insulin, I can. My cheat twice a week is a glass of lemonade. I look forward to it, and adjust for the carbs.
Suggestions:
1) Find a better doctor, yours sucks.
2) Ask for the ER or XR version of Metformin, it is far easier on your digestion.
3) No soda, no sugar, no diet soda, no sugar free anything. My sugar will rise with any diet product.
4) Reduce your carbs. No fruit other than berries, no peas, no beans, no corn. No bread, pasta or rice of any kind. Ditto, no cookies or pastry.
5) Have your eyes checked. See an endocrinologist.
6) Drink water, it dilutes the sugar in your system.
7) Get a Relion meter at Walmart and test test test. Minimum three times a day. You need to see what is going on.
Your sugar is so high, you may need the ER to give you insulin to bring it down to safe levels. If you feel faint, or equally sick, go.
Keep us posted on your progress. You can do this.
