People without diabetes have normal blood glucose levels
If you don’t have diabetes, your food is digested in your stomach and changed into glucose (a kind of sugar). The glucose travels in your bloodstream to your body cells. Insulin produced by your pancreas allows the glucose to enter your body cells and gives them energy.
People with diabetes have blood glucose levels that are too high
Your pancreas is not making enough insulin, or the insulin it makes does not work well. Either way, without insulin your cells can’t get the glucose they need. Instead, the glucose builds up in your bloodstream, so the cells 'starve' while the glucose level in the blood rises.
When your blood glucose level gets very high, your body gets rid of the glucose and calories through your urine. As a result, you may have one or more of the following signs:
Diabetes is a chronic disease
Diabetes is a chronic disease. It does not go away, even with treatment. It is also progressive, meaning that if left untreated, it can lead to difficult complications. The good news is that diabetes can be controlled. However, it must be carefully monitored to keep it in control.
A treatment plan that works at first may need to be adjusted as time passes to keep your blood glucose in its “target range”, where it should be most of the time. Your health care team will work with you to decide the blood glucose target ranges that are right for you.
