Question from Australia:

I believe I was misdiagnosed with type 1 diabetes at the end of September 2006. The diagnosis was based on an OGTT. My fasting level was 9.7 mmol/L [175 mg/dl]; one hour – 14.6 mmol/L [263 mg/dl]; and two hours – 18.8 mmol/L [338 mg/dl]. Also, my A1c at diagnosis was only 5.5., with a C-Peptide level of 0.68. I’m 156 cm (5 feet, 1 inch), 43 kilos (95 pounds), and have been told my diabetes was caught very early, in the pre-clinical stage.

I started on Lantus only after a stay in the hospital a few weeks after diagnosis. My blood sugar at the hospital was 24.4 mmol/L [439 mg/dl]. I was told I had lactic acidosis, but I was treated for DKA. Other medications at the time were Seretide, Somac, and Ventolin via metered dose inhaler, as needed. I stayed in the hospital for four days. A couple of days later, I was admitted to the hospital again. I skipped the Lantus as I was having trouble injecting and again stayed in hospital for four days. Since then, I have only had two episodes of high blood sugars (low 20s mmol/L [about 380 mg/dl]) and ketones. Currently, I take a small dose of Lantus, plus NovoRapid before meals.

All of a sudden, I’m getting low blood sugars. I experimented yesterday by greatly restricting my carbohydrate intake and taking no NovoRapid or Lantus. I went low, 3.9 mmol/L [70 mg/dl] in the late afternoon.

So, is it possible that I was misdiagnosed? Or, is it possible that whatever caused my high blood sugars has resolved now? I still get slightly elevated readings, 10 mmol/L [180 mg/dl] to 12 mmol/L [216 mg/dl], but only when I’m not well, about two or three times a week I get unexplained fevers between 38 and 39 degrees Celsius, muscle/bone pain, basically flu-like symptoms and that seems to be the only time I ever get high readings.
