A blood sugar level less than 140 mg/dL (7.8 mmol/L) is normal. A reading between 140 and 199 mg/dL (7.8 mmol/L and 11.0 mmol/L) indicates prediabetes. A reading of 200 mg/dL (11.1 mmol/L) or higher after two hours suggests diabetes.

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.

For a person without any type of diabetes, blood sugar levels are generally between 70 to 130 mg/dL depending on the time of day and the last time they ate a meal. Newer theories about non-diabetic blood sugar levels have included post-meal blood sugar levels as high as 140 mg/dL.

Hyperglycemia is a condition in which an excessive amount of glucose circulates in the blood plasma. This is generally a blood sugar level higher than 11.1 mmol/l (200 mg/dl), but symptoms may not start to become noticeable until even higher values such as 13.9–16.7 mmol/l (~250–300 mg/dl).

Generally, to correct a high blood sugar, one unit of insulin is needed to drop the blood glucose by 50 mg/dl. This drop in blood sugar can range from 30-100 mg/dl or more, depending on individual insulin sensitivities, and other circumstances.

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.

A normal healthy person will have an HbA1c level under 42 mmol/mol. Pre-diabetes ranges from 43-47 mmol/mol. Above that is diabetic level.

'Hyperglycemia,' or high fasting blood sugar levels of between 100-150 mg/dL, might indicate pre-diabetes and levels above this range may indicate diabetes. A number of other conditions may cause hyperglycemia too, including: Acromegaly. Pancreatitis.

Moderate to severe high blood sugar If your blood sugar levels are consistently high (usually above 20 mmol/L in adults and above 14 mmol/L in children), you may have moderate to severe symptoms of high blood sugar. These symptoms include: Blurred vision. Extreme thirst.

Fasting Blood Sugar Levels People with a blood sugar level between 95-99 were 2.33 times more likely to develop diabetes than people with normal blood sugar levels. And even people with a blood sugar level between 90-94 were 1.49 times more likely to develop diabetes.

Normal blood sugar levels are less than 100 mg/dL after not eating (fasting) for at least eight hours. And they're less than 140 mg/dL two hours after eating. During the day, levels tend to be at their lowest just before meals.

Fasting hyperglycemia is defined as when you don't eat for at least eight hours. Recommended range without diabetes is 70 to 130mg/dL. (The standard for measuring blood glucose is "mg/dL" which means milligrams per deciliter.) If your blood glucose level is above 130mg/dL, that's fasting hyperglycemia.

Oral glucose tolerance test. For this test, you fast overnight, and the fasting blood sugar level is measured. Then you drink a sugary liquid, and blood sugar levels are tested periodically for the next two hours. A blood sugar level less than 140 mg/dL (7.8 mmol/L) is normal.

The American Diabetes Association recommended an HbA1c level of 39 mmol/mol (5.7%) [1] and the Japan Diabetes Society recommended a level of 38 mmol/mol (5.6%) [2] as the cut-off for a high-risk group.
