What Is Diabetes?

Diabetes means your blood glucose (often called blood sugar) is too high. After a meal, food is broken down into a sugar called glucose. Your blood always has some glucose in it because your body needs glucose for energy to keep you going. But too much glucose in the blood isn’t good for your health.

How do you get high blood glucose?

Glucose comes from the food you eat and is also made in your liver and muscles. Your blood carries the glucose to all the cells in your body. Insulin is a chemical (a hormone) made by the pancreas. The pancreas releases insulin into the blood. Insulin helps the glucose from food get into your cells. If your body doesn’t make enough insulin, or if the insulin doesn’t work the way it should, glucose can’t get into your cells. It stays in your blood instead. Your blood glucose level then gets too high, causing pre-diabetes or diabetes. Over the years, high blood glucose, also called hyperglycemia, damages nerves and blood vessels, which can lead to complications such as heart disease and stroke, kidney disease, blindness, nerve problems, gum infections, and amputation.

What are the signs of diabetes?

• Being very thirsty
• Urinating often
• Feeling very hungry or tired
• Losing weight without trying
• Having sores that heal slowly
• Having dry, itchy skin
• Losing the feeling in your feet or having tingling in your feet
• Having blurry eyesight

You may have had one or more of these signs before you found out you had diabetes. Or you may have had no signs at all. A blood test to check your glucose levels will show if you have pre-diabetes or diabetes.
