[QUOTE="phoenix, post: 323213, member: 12578"] I don't think a c peptide test would demonstrate anything. It's value as a diagnostic test in in the fairly recently diagnosed, not someone who has had diabetes for 16 years. A person with new type 2 diabetes often has a normal or high level of C-peptide in the blood. Over time, a person with type 2 may lose beta cells ( their number reduce as we age in any case) A person with long standing T2 diabetes may develop quite low levels of C-peptide. [url=http://labtestsonline.org/understanding/analytes/c-peptide/tab/test]http://labtestsonline.org/understanding ... e/tab/test[/url] Insulin resistance isn't really a have it or you don't have it. It's a continuum, some people are more insulin resistant than others and it can vary according to what we're doing/eating but it is one of the characteristics of T2 diabetes. On the face of it , the amount of insulin you need plus the metformin you take would suggest that you are more insulin resistant rather than sensitive so (and I'm not a doctor and don't know your history ie when you first went onto insulin and why) I would guess that you are a T2 who now has insufficient of your own insulin so need to supplement it. I think the confusion about insulin dependence and non insulin dependence comes from the older and confusing names for T1 and T2 Type 1 used to be called IDDM (insulin dependent diabetes melitus) and what is now called T2 was called NIDDM (non..) even when the person went onto insulin Heres what was written in a 1990 paper But as Mileana says someone who is T2 and needs to take insulin to keep their levels down really needs it and neglected/untreated diabetes can lead to the HHNS she mentions It just takes longer to get into that condition than it does for someone with T1 to develop DKA. In the sense of keeping yourself healthy and preventing the damage from high glucose , you are dependent on insulin . [/QUOTE]
