When is insulin produced in the body?

Expert Answers

In a healthy body, the pancreas continually produces insulin but produces more when blood sugar (glucose) rises.

Insulin is a hormone used to regulate carbohydrates and fat in the body, known as glucose (blood sugar).  It is very important, because without it our bodies will shut down when glucose builds up.   Insulin is produced by cells in the pancreas, the islets of Langerhans.  When there is a rise in your blood sugar (glucose), your pancreas reacts by producing more insulin.

Some people’s bodies do not produce insulin.  These are diabetics.  Type I diabetics need to inject themselves with insulin, and Type II diabetics can produce some on their own.
