- n. Any of various pharmaceutical preparations containing this hormone that are derived from the pancreas of certain animals or produced through genetic engineering and are used in the medical treatment and management of diabetes mellitus (type I).

Unfortunately, if insulin levels are always high, then the sensitive insulin receptors on your body¹s cells eventually become unresponsive to insulin, resulting in a host of problems related to what is called ³insulin insensitivity².
REESE: Well, 16 million people have what they call insulin resistance, 60 million people have it, but 16 million are definitely going to have to deal with type 2 diabetes.
Type 2 diabetes is a condition in which patients are able to produce a hormone called insulin, which is needed to metabolize blood sugar or glucose, but somehow cannot use insulin effectively.
The term insulin resistance doesn’t adequately encompass related factors such as insulin sensitivity ISI or beta cell function.
It's not uncommon for a doctor to make small changes in insulin to find the dose that works best.
Food won't change the rate at which insulin is absorbed into the blood, but it does affect your blood sugar in general.
Incidentally, there was no difference in insulin resistance or diabetes between the two groups.
This uses a radioactive drug, 18F-DOPA, that is injected intravenously and concentrates in insulin cells for detection in a PET scanner (positron emission tomography).
With HI, the secretion of insulin is not properly regulated, causing excess insulin secretion and low blood sugar.
This condition is called insulin resistance and it leads to high blood sugar, high blood levels of fat triglycerides and high blood pressure.
