[IP] Re: Type 2 on insulin

>>From: Linda Kelly <email @ redacted>
C-peptide tells how much insulin your body produces.  It shows a high number
with Type 2, low number can be type 2 also.<<

Thanks for clearing that up.  I see many people post saying a 
C-peptide will determine if you are a Type 1 or 2 when it does not.

Here is an explanation from 

How is it (C-peptide test) used?
When a patient has newly diagnosed type 1 or type 2 diabetes, 
C-peptide can be used to help determine how much insulin the 
patient's pancreas is still producing and whether or not that insulin 
is being used effectively.

Type 1 diabetes is an autoimmune process that often starts in early 
childhood and involves the almost complete destruction of the beta 
cells over time.  Eventually, little or no insulin (or C-peptide) is 
produced, leading to a complete dependence on exogenous insulin.

In type 2 diabetes, often called "adult-onset diabetes," a 
combination of factors leads to decreased insulin production and 
increased insulin resistance, along with some beta cell damage.  Type 
2 diabetics usually are treated with oral drugs to stimulate their 
body to make more insulin and/or to cause their cells to be more 
sensitive to the insulin that is already being made.  Eventually, 
type 2 diabetics may make very little insulin and require injections. 
Any insulin that the body does make will be reflected in their 
C-peptide level; therefore, the C-peptide test can be used to monitor 
beta cell activity and capability over time and to help your doctor 
determine when to  begin supplementing your insulin.

C-peptide measurements also can be used in conjunction with insulin 
and glucose levels to help diagnose the cause of documented 
hypoglycemia and to monitor its treatment.  Symptoms of hypoglycemia 
may be caused by excessive supplementation of insulin, alcohol 
consumption, inherited liver enzyme deficiencies, liver or kidney 
disease, or insulinomas (tumors of the islet cells in the pancreas 
that can produce uncontrolled amounts of insulin and C-peptide).
