Diabetes and Insulin
Made by the beta cells in your pancreas, insulin is
a key hormone. Insulin helps sugar, or
glucose, move from your blood into your cells. This lowers your blood
sugar levels. Whatʼs more, the cells of your body use this blood sugar for fuel,
so insulin is very important.
Without enough insulin, blood sugar cannot be moved to parts of the body that need
it. This can result in high blood sugar. High blood sugar can then cause many different
problems that are considered signs or symptoms of diabetes. These symptoms may
include extreme thirst or hunger, weight loss, or feeling unusually tired and irritable.
Diabetes is a condition in which sugar levels in your blood are high. With diabetes,
the body may not be able to produce enough insulin or to use insulin the right way.
It may be that the body does not produce any insulin at all. Without insulin to
help the body use blood sugar, blood sugar levels increase in the body. This is
why most people with diabetes require treatment to lower blood sugar levels.
