Normal fasting blood glucose -- or blood sugar -- is between 70 and 100 milligrams per deciliter or mg/dL for people who do not have diabetes. The standard diagnosis of diabetes is made when two separate blood tests show that your fasting blood glucose level is greater than or equal to 126 mg/dL.
Can you test yourself for diabetes?
You may have type 2 diabetes. To find out, you can make an appointment with your doctor and have your blood tested for the condition. Or you can go to the drug store, buy a blood glucose meter, and give yourself a diabetes test.
What is the blood test for diabetes?
The A1C test is a blood test that provides information about your average levels of blood glucose, also called blood sugar, over the past 3 months. The A1C test can be used to diagnose type 2 diabetes and prediabetes. The A1C test is also the primary test used for diabetes management.
Your health care professional can diagnose diabetes, prediabetes, and gestational diabetes through blood tests. The blood tests show if your blood glucose, also called blood sugar, is too high. Testing equipment that you can buy over the counter, such as a blood glucose meter, cannot diagnose diabetes.
A fasting blood sugar level from 100 to 125 mg/dL (5.6 to 6.9 mmol/L) is considered prediabetes. If it's 126 mg/dL (7 mmol/L) or higher on two separate tests, you have diabetes. Oral glucose tolerance test. For this test, you fast overnight, and the fasting blood sugar level is measured.
Fasting Plasma Glucose –This blood test is taken in the morning, on an empty stomach. A level of 126 mg/dl or above, on more than one occasion, indicates diabetes. Casual or Random Glucose - This blood test can be taken anytime during the day, without fasting.
3 tips to lower your blood sugar fast
- Hydrate. The more water you drink, the better.
- Exercise. Exercise is a good way to get better blood sugar control and keep your blood sugar levels in a healthy range as a part of your routine diabetes management.
- Eat a protein-packed snack.
Therefore, it's important to avoid the foods listed below.
- Sugar-Sweetened Beverages. Sugary beverages are the worst drink choice for someone with diabetes.
- Trans Fats.
- White Bread, Pasta and Rice.
- Fruit-Flavored Yogurt.
- Sweetened Breakfast Cereals.
- Flavored Coffee Drinks.
- Honey, Agave Nectar and Maple Syrup.
- Dried Fruit.
Urine tests for diabetes facts. Urine tests may be done in people with diabetes to evaluate severe hyperglycemia (severe high blood sugar) by looking for ketones in the urine. Ketones are a metabolic product produced when fat is metabolized. Ketones increase when there is insufficient insulin to use glucose for energy.
Until recently, a normal fasting blood glucose level under 110 mg/dl was considered to be normal and fasting blood glucose in the range of 110 to 125 mg/dl indicated impaired fasting glucose (IFG), or prediabetes. A blood glucose level 200 mg/dl or higher two hours after the drink indicates diabetes.
Prediabetes is a “pre-diagnosis” of diabetes—you can think of it as a warning sign. It's when your blood glucose level (blood sugar level) is higher than normal, but it's not high enough to be considered diabetes. But here's the good news: it is possible to prevent prediabetes from developing into type 2 diabetes.
When the A1C test is used to diagnose diabetes, an A1C level of 6.5 percent or higher on two separate occasions indicates you have diabetes. A result between 5.7 and 6.4 percent is considered prediabetes, which indicates a high risk of developing diabetes.
The key was weight loss, whereupon the diabetes often goes away or at least gets significantly better. So, logically, insulin does not help reverse the disease, but actually worsens it. Since weight loss is the key to reversing type 2 diabetes, medications won't make things better.
Normal and diabetic blood sugar ranges. For the majority of healthy individuals, normal blood sugar levels are as follows: Between 4.0 to 5.4 mmol/L (72 to 99 mg/dL) when fasting. Up to 7.8 mmol/L (140 mg/dL) 2 hours after eating.
Diabetes is a chronic condition associated with abnormally high levels of sugar (glucose) in the blood. Insulin produced by the pancreas lowers blood glucose. Absence or insufficient production of insulin, or an inability of the body to properly use insulin causes diabetes.
Controlling blood sugar (glucose) levels is the major goal of diabetes treatment, in order to prevent complications of the disease. Type 1 diabetes is managed with insulin as well as dietary changes and exercise. Type 2 diabetes may be managed with non-insulin medications, insulin, weight reduction, or dietary changes.
For someone without diabetes, a fasting blood sugar on awakening should be under 100 mg/dl. Before-meal normal sugars are 70–99 mg/dl. “Postprandial” sugars taken two hours after meals should be less than 140 mg/dl. There is also a long-term glucose test called a hemoglobin A1c, HbA1c, or just A1C.
Here are 15 easy ways to lower blood sugar levels naturally:
- Exercise Regularly.
- Control Your Carb Intake.
- Increase Your Fiber Intake.
- Drink Water and Stay Hydrated.
- Implement Portion Control.
- Choose Foods With a Low Glycemic Index.
- Control Stress Levels.
- Monitor Your Blood Sugar Levels.
Blood glucose tests are either random or fasting tests. For a fasting blood glucose test, you can't eat or drink anything but water for eight hours before your test.
Patients do not need to fast before the test is given, and it is far less likely to identify clinically irrelevant fluctuations in blood sugar because it measures average blood glucose levels over several months. The new guidelines do not call for replacing traditional screening with the A1C test.
Making these healthy changes can help you improve your day-to-day blood sugar management and lower your A1C:
- Move more. Try to get at least 30 minutes of exercise five days a week.
- Eat a balanced diet with proper portion sizes.
- Stick to a schedule.
- Follow your treatment plan.
- Check your blood sugar as directed.
For people without diabetes, the normal range for the hemoglobin A1c level is between 4% and 5.6%. Hemoglobin A1c levels between 5.7% and 6.4% mean you have a higher chance of getting diabetes. Levels of 6.5% or higher mean you have diabetes.
Here are some things you could try to reduce this occurrence:
- Eat a carbohydrate snack before bed.
- Reduce blood sugar-lowering medication or insulin in the evening.
- Reduce your long-acting insulin dose.
- Change your exercise schedule from afternoon or evening to first thing in the morning.
