Your body breaks
down the food you
eat into glucose
and other nutrients.
The body digests the food you eat to use as fuel.
This fuel supplies energy to your body’s cells.
When you have type 2 diabetes, the fuel has a
hard time entering most cells.
How the Body Gets Energy
The digestive system breaks down food,
resulting in a variety of nutrients including
sugar (glucose). Some of the glucose is stored
in the liver. Most of it enters the bloodstream
and travels to cells to be used as fuel. Glucose
needs the help of a hormone called insulin
to enter most cells. Insulin is made in the
pancreas. It is released into the bloodstream
in response to meals and also by the presence
of glucose in the blood. Think of insulin as a
key. When insulin reaches a cell, it
unlocks a doorway in the cell wall.
This creates an opening that allows
glucose to enter the cell. Some cells
do not need insulin and glucose can
enter them without it.
