@alaska since you are a T2 on insulin (I think?) do you have any ideas that might help Phil? Do you know of any other members who could be tagged in?
Actually I'm type 1 but have as much of an interest in type 2 as type 1.
Very high insulin requirements will mean high insulin resistance. I assume
@phil169 that there is significant weight to be lost?
The other factor that can significantly increase insulin resistance is steroids.
The way to combat insulin resistance, and high blood sugars as a result, is to reduce insulin intake. Calorie intake (unless already sufficiently low) should be reduced in turn.
This should be done only in agreement with the doctor.
Insulin fuels insulin resistance, so upping insulin doses may slightly alleviate high blood sugar in the immediate term
but it exacerbates the underlying problem of insulin resistance and is therefore likely to cause more problems in the longer run.
If you're on low carb and it's also low calorie, I'd expect to see blood sugar levels beginning to drop at least a little after 2-3 weeks.
Taking 100s of units of insulin is abnormal but don't worry, some people do take this much. The key is to turn things around so that the insulin doses are reducing rather than growing.
As an analogy, we can look at insulin resistance and electrical resistance. This may make sense for some. If it causes confusion, just ignore. If you have a resistor in an electrical circuit, the more voltage applied, the higher the resistance. In type 2 diabetes, the more insulin produced or taken in, the greater the insulin resistance.
