High BG is far from being fine, its causes so many problems as I found out over time. From my own experiences the docs know the symptoms of diabetes and get one diagnosed in most cases and that's about the end of their knowledge. After diagnosis they pass you on to the diabetic team be it in house or via the hospital. What they don't seam aware of is the damage running at high levels like above 8.5 and the teens is just as bad as someone who has levels in the 20's.
In my area the diabetic teams knowledge varies greatly from little to a top service and help, I left my previous docs as their latest DN was a dictator, she did not want to know how diabetes was affecting the individual, and was treated as a number and all the same. All the conversation was one way from her.
I moved to a practice that had one of the best DN in the area and was getting me sorted out, then she moved and the diabetic quality fell through the floor espec if like me, as so temperamental with the meds and how they work one day and not the next day and can be meds intolerant, probably a nightmare to the docs how I react to some meds.
Unless one is self driven about ones diabetes, its so easy to slip through the net, espec now as in my area you used to get calls or letters that reviews are due, now its mainly your own responsibility to make all the appointments. Think now the only one you get a appointment sent to you is the eye photography done at the hospital and in my area that has only recently been done at the hospital, up until then mine was done at the opticians.
I know of one diabetic, that was constantly running in the 20's + and as they were not self motivated in their care slipped through the net of the doctors screening. Yet at the time they had experienced no problems or felt they had no problems unlike myself who seams to be affected as soon as levels rise above 10.0. After gentle prodding they have started taking an interest at least enough to get their levels back down to more realistic levels.
