I went two years having blood sugar nos. above 200. I finally said-please refer me to an endocrinologist. Luckily I had found a wonderful specialist who had an in-house dietician. She said that all the other drs. were overdosing my insulin and I had become “insulin intolerant”. Within a week she had my levels normal and gave me a workable plan as I worked with the dietician. The high levels caused health issues (neuropathy and kidney issues) but at least I have a plan with a positive outlook. Don’t be afraid to do the research needed to find the best care.
