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.
What do they look for in a glucose blood test?
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.
The American Diabetes Association recommends aiming for a blood sugar level between 70 to 130 mg/dl before meals and less than 180 mg/dl one to two hours after a meal.
Low blood sugar is called hypoglycemia. A blood sugar level below 70 mg/dL (3.9 mmol/L) is low and can harm you. You are at risk for low blood sugar if you have diabetes and are taking any of the following diabetes medicines: Insulin.
Q: Do I have diabetes if my glucose blood test readings have gone up from 94 to 102 over past 2 years. A: 102 is a diagnosis of pre-diabetes. A fasting level anywhere from 100-125 is considered pre-diabetes. Two fasting levels of 126 or greater is a diagnosis of diabetes.
Signs and Symptoms of Hypoglycemia (happen quickly)
- Nervousness or anxiety.
- Sweating, chills and clamminess.
- Irritability or impatience.
- Confusion, including delirium.
- Rapid/fast heartbeat.
- Lightheadedness or dizziness.
- Hunger and nausea.
(Click here for a blood sugar chart.) 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.
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.
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.
Post-Meal Blood Sugar (Postprandial) Independent of what they eat, the blood sugars of truly normal people are: Under 120 mg/dl (6.6 mmol/L) one or two hours after a meal. Most normal people are under 100 mg/dl (5.5 mmol/L) two hours after eating.
Blood glucose is commonly considered too high if it is higher than 130 mg/dl before a meal or higher than 180 mg/dl two hours after the first bite of a meal. However, most of the signs and symptoms of high blood glucose don't appear until the blood glucose level is higher than 250 mg/dl.
The normal blood glucose level (tested while fasting) for non-diabetics, should be between 3.9 and 5.5 mmol/L (70 to 100 mg/dL). Blood sugar levels for those without diabetes and who are not fasting should be below 6.9 mmol/L (125 mg/dL).
Yes, there is a safe blood sugar level. It is the optimum range that safely provides the body with adequate amounts of energy. For the average person, it is 70 to 105 mg/dl in a fasting state. (Diabetes is diagnosed when the fasting blood glucose level is at or above 126 mg/dl.)
The blood sugar (or glucose) level is displayed digitally within seconds. Blood glucose levels vary widely throughout the day and night in people with diabetes. Ideally, blood glucose levels range from 90 to 130 mg/dL before meals, and below 180 mg/dL within 1 to 2 hours after a meal.
Hyperglycemia means high (hyper) glucose (gly) in the blood (emia). Your cells rely on glucose for energy. Hyperglycemia is a defining characteristic of diabetes—when the blood glucose level is too high because the body isn't properly using or doesn't make the hormone insulin.
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.
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.
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.
Fasting hyperglycemia. This is blood sugar that's higher than 130 mg/dL (milligrams per deciliter) after not eating or drinking for at least 8 hours. Postprandial or after-meal hyperglycemia. This is blood sugar that's higher than 180 mg/dL 2 hours after you eat.
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.
If your blood sugar level is too high, you may experience:
- Increased thirst.
- Frequent urination.
- Nausea and vomiting.
- Shortness of breath.
- Stomach pain.
- Fruity breath odor.
- A very dry mouth.
The A1C test measures the glucose (blood sugar) in your blood by assessing the amount of what's called glycated hemoglobin. An A1C level below 5.7 percent is considered normal. An A1C between 5.7 and 6.4 percent signals prediabetes. Type 2 diabetes is diagnosed when the A1C is over 6.5 percent.
