I played golf with a guy who has type 2 diabetes. He had 2 episodes of low glucose during the round. Why? He had taken extra insulin to "cover" the dinner and lemon cake he had the night before. He was chasing his blood sugar readings with insulin.
Even though his pancreas still produces insulin, he does not know what his fasting insulin is. Insulin injections make his insulin resistance worse. How is he ever going to improve by going down the injection path?
I lived with diabetes in family members for more than 30 years and have read most of what is written about it in the journals. I am working on a series of posts on that topic.
