What is prediabetes?
Prediabetes is a term that is used when you are at risk for type 2 diabetes. It means that your blood sugar is higher than it should be. Most people who get type 2 diabetes have prediabetes first. The good news is that lifestyle changes may help you get your blood sugar back to normal and avoid or delay diabetes.
Type 2 diabetes is a lifelong disease that happens when the pancreas can't make enough insulin and/or the body's tissues can't use insulin properly. Insulin is a hormone that helps the body's cells use sugar (glucose) for energy. It also helps the body store extra sugar in muscle, fat, and liver cells.
Without insulin, the sugar can't get into the cells to do its work. It stays in the blood instead. This can cause high blood sugar levels. A person has diabetes when the blood sugar stays too high too much of the time.
Over time, high blood sugar can cause serious problems with the eyes, heart, blood vessels, nerves, and kidneys. High blood sugar also makes a person more likely to get serious illnesses or infections.
