I have recently been told that after 30 years of being treated as a type 1 diabetic I am now diagnosed as type 2. I feel upset by this as after 30 years of high dose insulin I should of been cared for differently. Maybe no insulin needed when diagnosed. Has anybody else had this diagnosis and I'd appreciate people's thoughts. Thanks in advance.
One interesting thing.
At the Diabetes UK conference two years ago there was a lot of excitement about the discovery of "guerrilla Beta cells". That is, Beta cells which had been masquerading as Alpha cells to avoid attack by the immune system and occasionally popping up again as Beta cells.
I have no idea what progress has been made since, but it might be possible that your Beta cells hadn't been entirely destroyed by your own immune system and the long time on insulin allowed them to slowly recover.
I know, also, that there was discussion on here a few years back about a strategy of putting T2s on insulin immediately after diagnosis to take the load off the pancreas whilst the underlying cause (insulin resistance I assume) was sorted out.
Another possibility, then, is that something in your body and/or diet has change enough to reduce or remove any insulin resistance so that now your pancreas can produce enough insulin to manage your BG. This could have happened at any time, including soon after diagnosis.
Once you are diagnosed as a T1 on insulin then usually that is you defined for life.
However if you have a functioning pancreas I am a little puzzled about how this was noticed now and not earlier.
I would have expected that your insulin requirements would have been fairly low which should have been a hint for further investigations.
Unless they have decided that you are a T2 with an under producing pancreas, so that a diet quite high in carbohydrates which is matched by injected insulin concealed the fact that you were still producing your own insulin.
More information, please!
Edit: "high dose insulin" suggests either very little self produced insulin, or a high degree of insulin resistance plus a high carbohydrate diet.
