Hi all,

On Sept 5th 2011, I suffered a heart attack, had stent surgery, and then was told I am type 1 and type 2 diabetic. So as you can imagine, that was one crazy morning. I was 38 at the time, and weighed 66kg's (145 pounds).

That morning, I had a HBA1c of 12.2%, and an Islet Cell Ab test showing positive.

Since then, I have been full on with dieting (eating small amounts of low GI food, low fat products, high protein foods, lots of fruit and vegetables) and of course taking all my heart medications. The only insulin I take is 30 units of long acting Lantus, 1 injection per night before bed.

I test my sugar levels every 2 hours or so, and I am 88% within safe range.

Recently I had a full pathology test, which shows my HBA1c of 5.8%, but what is really interesting is my Islet Cell Ab test now shows as negative.

Out of curiosity does anyone know what this means exactly?

Any insight you can provide is most appreciated.

Kind regards,

I can't believe it…no offense to anyone here, but, I FINALLY found someone else that was told they have type 1 and type 2…I tested positive for antibodies, whatever that means, and a C-peptide test showed I produce from 3%-10% of my own insulin. I am confused to a degree, as, HOW, then, have I gotten by on so little insulin—I have only had slow acting insulin on one day in the emergency room in 2009, and then regular insulin on one day in the emergency room in 2005—-I feel like crap most of the time , but, HOW, then, if I am both types, is my body not dying? I am THANKFUL I have not died, but, does anybody know? Dolcevita2, my THEORY, and this is just a theory, is that , being we are both types, our bodies must produce SOME insulin on our own, and then store it, and therefore, our test results change. I would just BEG anyone to give me some answers, as , I am still looking for a new endo..the one I had was outstanding, but, he had a terrible nurse practitioner. What's even crazier yet is I am also diagnosed as very brittle, and I honestly feel like my pancreas overproduces insulin, then it stops producing for awhile, then it produces a tiny bit, then it stops again.

Natural insulin is very different to injected insulin. It's basically immediate acting and gone in a flash. It sounds like you have LADA or type 1.5 diabetes, your story is pretty close a textbook definition.
