This is very interesting and informative. It doesn't surprise me that T2 use more insulin than T1. Do you think that it has anything to do with27% of type 2 diabetics use insulin. Here is the link that makes that statement. It is based on data from the year 2004.
Insulin Therapy for Type 2 Diabetes: Rescue, Augmentation, and Replacement of Beta-Cell Function - August 1, 2004 - American Family Physician
There are approximately 24 million diabetics in the US, based on 2007 data. About 10% of them are type 1, and 90% are type 2. So there were 2,400,000 type 1's and 21,600,000 type 2's in 2007. Since 27% of the type 2's use insulin, and 100% of the type 1's use insulin, there were 2,400,000 type 1's using insulin, and 5,832,000 type 2's using insulin. So there are 3,432,000 more type 2 insulin users than type 1 insulin users. The insulin companies make a lot more money off type 2's than type 1's.
the fact that T1 are more likely to use a pump, therefore eliminating the need for a long acting insulin such as Lantus?
