When you have diabetes, your blood sugar (aka blood glucose) levels may be consistently high. Over time, this can damage your body and lead to many other problems. How much sugar in the blood is too much? And why is high glucose so bad for you? Here’s a look at how your levels affect your health. They're less than 100 mg/dL after not eating (fasting)
for at least 8 hours. And they're less than 140 mg/dL 2 hours after eating. During the day, levels tend to be at their lowest just before meals. For most people without diabetes, blood sugar levels before meals hover around 70 to 80 mg/dL. For some people, 60 is normal; for others, 90. What's a low sugar level? It varies widely, too. Many people's glucose won't ever fall below 60, even with prolonged fasting. When you diet or fast, the liver keeps your levels normal by turning fat
and muscle into sugar. A few people's levels may fall somewhat lower. Doctors use these tests to find out if you have diabetes: Any sugar levels higher than normal are unhealthy. Levels that are higher than normal, but not reaching the point of full-blown diabetes, are called prediabetes. According to the
American Diabetes Association, 86 million people in the U.S. have this condition, which can lead to diabetes if you don't make healthy lifestyle changes that your doctor recommends. It also raises the risk for heart disease, although not as much as diabetes does. It's possible to keep prediabetes from becoming diabetes with diet and exercise. Sugar and Your BodyWhy are high blood sugar levels bad for you? Glucose is precious fuel for all the cells in your body when it's present at normal levels. But it can behave like a slow-acting poison.
Almost any part of your body can be harmed by too much sugar. Damaged blood vessels cause problems such as:
Keep your blood sugar levels close to normal to avoid many of these complications. The American Diabetes Association's goals for blood sugar control in people with diabetes are 70 to 130 mg/dL before meals, and less than 180 mg/dL after meals.
Normally, your pancreas releases insulin when your blood sugar, or “blood glucose,” gets high -- after a meal, for example. That signals your body to absorb glucose until levels get back to normal. But if you have diabetes, your body doesn’t make insulin (type 1 diabetes) or doesn’t respond to it normally (type 2 diabetes). That can leave your blood sugar too high for too long. Over time, that can damage nerves and blood vessels and lead to heart disease and other problems. If you have diabetes, your doctor may ask you to keep track of your blood sugar by testing it at home with a special device called a blood glucose monitor or home blood sugar meter. It takes a small sample of blood, usually from the tip of your finger, and measures the amount of glucose in it. Follow your doctor’s instructions about the best way to use your device. Your doctor will tell you when and how to test your blood sugar. Each time you do it, log it in a notebook or online tool or in an app. The time of day, recent activity, your last meal, and other things can all affect whether a reading will be of concern to your doctor. So try to log relevant information like:
That will help you and your doctor see how your treatment is working. Managing type 1 and type 2 diabetes well can delay or prevent complications that affect your eyes, kidneys, and nerves. Diabetes doubles your risk for heart disease and stroke, too. Fortunately, controlling your blood sugar will also make these problems less likely. Tight blood sugar control, however, means a greater chance of low blood sugar levels, so your doctor may suggest higher targets. What is a normal blood sugar level for non diabetic?For adults without diabetes, a normal fasting blood sugar is less than 100 mg/dL. A fasting blood sugar level of 100-125 mg/dL indicates prediabetes, and 126 mg/dL or higher indicates diabetes.
What is normal sugar level by age without diabetes?So, the NutriSense Team recommends aiming for the same guidelines for healthy children/adults without diabetes, keeping glucose between 70-140 mg/dL. For teenagers with diabetes, glucose should stay between 70-150 mg/dL throughout the day.
What is normal random blood sugar level in adults?Random Blood Sugar Test. What is normal blood sugar by age?From 90 to 130 mg/dL (5.0 to 7.2 mmol/L) for adults. From 90 to 130 mg/dL (5.0 to 7.2 mmol/L) for children, 13 to 19 years old. From 90 to 180 mg/dL (5.0 to 10.0 mmol/L) for children, 6 to 12 years old. From 100 to 180 mg/dL (5.5 to 10.0 mmol/L) for children under 6 years old.
