I'm asked all the time what the difference is between Type 1 and Type 2 Diabetes. I'm a Type 1 and I wear an Insulin Pump that pushes insulin into my system 24 hours a day. Sometimes folks will say, "Oh, my uncle has diabetes, he got it when he was fifty" and assume it's just like mine.
Type 1 diabetics don't produce enough insulin and need augmentation. Type 2 diabetics product too much because they are resistant to their own insulin. Both of us have high blood sugar because we're not using insulin effectively. Here's a very clear difference:
Dr. Michael Murray clearly identifies the difference between type 1 and type 2 diabetes when he states, "Healthy individuals secrete approximately 31 units of insulin daily; the obese type 2 individual secretes an average of 114 units daily. Individuals with type 1 diabetes secrete only 4 units of insulin daily."
This is totally true, because I use about 30 units of insulin each day delivered from my pump.
