What is blood sugar?
Blood sugar, or glucose, is the main sugar found in the blood. It comes from food that’s eaten, and is the body's main source of energy. Blood carries glucose to all of the body's cells to use for energy.
What are healthy normal blood sugar levels?
Blood sugar levels are typically tested after fasting. The ideal blood sugar level is between 70 and 100 mg/dL.
If you get your blood sugar levels when you haven't fasted, which is called a “random blood glucose test”, a normal result depends on when food was last eaten. Most of the time, the blood sugar level will be below 125 mg/dL.
What is prediabetes?
Prediabetes is when blood sugar levels are 100–125 mg/dL, which is above the ideal range. 1 out of 3 American adults have prediabetes, and 90% of them don’t even know it!
Prediabetes is not a disease, and lifestyle changes can be made to address it.
What can be done to avoid elevated blood sugar levels?
Working to keep a healthy blood sugar level is an important part of staying healthy. Some steps to help maintain a healthy blood sugar level include:
• Take your usual medicines at the usual times
• Move more, even if it's around your house or at work
• Drink several glasses of water or sugar-free liquids (without caffeine)
• Eat your regularly planned meals
• Check and record your blood sugar every four hours until it is back to normal
