Understanding blood glucose level ranges can be a key part of diabetes self-management.
This page states ‘normal’ blood sugar level ranges and blood sugar ranges for adults and children with type 1 diabetes, type 2 diabetes and blood sugar ranges to determine people with diabetes.
Recommended blood glucose level ranges have a degree of interpretation for every individual and you should discuss this with your healthcare team.
In addition, women may be set target blood sugar levels during pregnancy.
As a result, the following ranges are guidelines provided by the National Institute for Clinical Excellence (NICE). Therefore, each individual’s target range should be agreed by their doctor or diabetic consultant.
Recommended target blood glucose level ranges
The NICE recommended target blood glucose level ranges are stated below. For adults with type 1 diabetes, type 2 diabetes and children with type 1 diabetes.
The table provides general guidance. An individual target set by your healthcare team is the one you should aim for.
*The non-diabetic figures are provided for information but are not part of NICE guidelines.
Normal and diabetic blood sugar level 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
For people with diabetes, blood sugar level targets are as follows:
- Before meals: 4 to 7 mmol/L for people with type 1 or type 2 diabetes
- After meals: under 9 mmol/L for people with type 1 diabetes and under 8.5mmol/L for people with type 2 diabetes
Blood sugar levels in diagnosing diabetes
The following table lays out criteria for diagnoses of diabetes and pre-diabetes.
Random plasma glucose test
A blood sample for a random plasma glucose test is taken at any time. This doesn’t require as much planning and is therefore used in the diagnosis of type 1 diabetes when time is of the essence.
Fasting plasma glucose test
A fasting plasma glucose test is taken after at least eight hours of fasting and is therefore usually taken in the morning.
The NICE guidelines regard a fasting plasma glucose result of 5.5 to 6.9 mmol/l as putting someone at higher risk of developing type 2 diabetes, particularly when accompanied by other risk factors for type 2 diabetes.
Oral Glucose Tolerance Test (OGTT)
An oral glucose tolerance test involves taking a first taking a fasting sample of blood and then taking a very sweet drink containing 75g of glucose.
While you having this drink you need to stay at rest, until a further blood sample is taken after 2 hours.
HbA1c test for diabetes diagnosis
An HbA1c test does not directly measure the level of blood glucose. Because, each result of the test is encouraged with the aid of how excessive or low your blood glucose ranges have tended to be over a duration of 2 to 3 months.
consequently, symptoms of diabetes or pre-diabetes are given beneath the following conditions:
- Normal: Below 42 mmol/mol (6.0%)
- Pre-diabetes: 42 to 47 mmol/mol (6.0 to 6.4%)
- Diabetes: 48 mmol/mol (6.5% or over)
Why are good blood sugar levels important?
It is important that people control their blood glucose levels as well as they can. Because, too high sugar levels for long periods of time increases the risk of diabetes complications developing.
Diabetes complications are health problems which include:
This list of problems may look scary. People can make a notice that the risk of these problems can be minimized via properly blood glucose level ranges control.
Small improvements in the way of eating can make a big difference if you stay dedicated and maintain those improvements over most days.
