What are good blood sugar levels for type 2 diabetes

A1C level. This is a blood test, typically given at doctor's appointments, that measures your average blood sugar levels over a longer period. “It gives you a picture of what’s been going on over the past two to three months,” says Dawn Sherr, RD, a certified diabetes educator and spokesperson for the American Association of Diabetes Educators. Essentially, your A1C result shows how well your diabetes treatment plan is working.

Depending on your results, you may need to have the test from two to four times a year. For most people, an A1C level of 7 percent or less is ideal. If your A1C level is higher, you and your doctor may discuss making changes to your diabetes treatment plan. Healthy lifestyle practices, like consistent blood sugar control and regular physical activity, can help keep your A1C levels low.

Blood pressure. Monitoring your blood pressure is another important way to maintain your health. “People with diabetes are more likely to develop heart disease, and blood pressure is a big factor in that,” Sherr says.

Your blood pressure should be checked several times a year — ideally, every time you see the doctor who is treating your diabetes, Sherr says. Most people with diabetes should aim for a blood pressure of less than 140/80. To prevent high blood pressure, cut back on salt in your diet, exercise regularly, and quit smoking. Some people with type 2 diabetes may need to take medications to lower their blood pressure.

Cholesterol. This is a substance in your body with two components. Low-density lipoprotein (LDL) is known as bad cholesterol; it can build up in your arteries and contribute to heart disease. High-density lipoprotein (HDL) is called the good cholesterol and has a protective effect on your arteries. Your doctor will perform a blood test once a year to check your cholesterol levels, though you may have it checked more often if your numbers are high, Sherr says.

A test result of less than 100 mg/dl of LDL cholesterol is ideal, while HDL cholesterol should be above 40 mg/dl for men and 50 mg/dl for women. Triglycerides, a type of blood fat that can increase your risk of heart disease, should be less than 150 mg/dl for both men and women. If your cholesterol levels are outside these ranges, you can improve them by losing excess weight, exercising, and eating a healthy diet that’s rich in fresh produce and low in fat.

BMI. Short for body mass index, this is a measure that uses your height and weight to estimate how much body fat you have. Since managing weight plays a role in controlling type 2 diabetes, a healthy BMI is important.

Your doctor will probably review your BMI annually, but you can also calculate it yourself by dividing your weight in pounds by your height in inches squared, and then multiplying that number by 703. Online calculators are also available to do the math for you. A healthy BMI ranges from 18.5 to 24.9 — anything over that is considered overweight, and a BMI over 30 is considered obese.

However, the measurement may not be accurate for some people, such as those with a large amount of muscle. “The BMI score can sometimes be deceiving and not the best way to look at the health effects of someone’s weight,” says Fernando Ovalle, MD, an endocrinologist and professor of medicine at University of Alabama at Birmingham College of Medicine. In these cases, other measurements may be used, such as waist-to-hip ratio and abdominal circumference.

Microalbumin. This test measures the amount of protein, or albumin, in your urine, which helps your doctor know how well your kidneys are working. Your doctor should administer this test at least once a year.

The test compares the level of albumin with the level of creatinine, a waste product. Your albumin-to-creatinine ratio should be less than 30, according to the National Institute of Diabetes and Digestive and Kidney Diseases. To keep your microalbumin results within a healthy range, it’s important to keep your kidneys healthy. High blood pressure and high blood sugar can both damage your kidneys, so controlling those factors will go a long way toward preventing kidney problems — and many other health problems — in the future.

Understanding blood glucose level ranges can be a key part of diabetes self-management.

This page states ‘normal’ blood sugar 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.

If a person with diabetes has a meter, test strips and is testing, it’s important to know what the blood glucose level means.

Recommended blood glucose levels 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

The following ranges are guidelines provided by the National Institute for Clinical Excellence (NICE) but 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 levels are stated below for adults with type 1 diabetes, type 2 diabetes and children with type 1 diabetes.

In addition, the International Diabetes Federation’s target ranges for people without diabetes is stated. [19] [89] [90]

The table provides general guidance. An individual target set by your healthcare team is the one you should aim for.

NICE recommended target blood glucose level ranges

*The non-diabetic figures are provided for information but are not part of NICE guidelines.

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 [361]
• 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 prediabetes.

Blood sugar levels in diagnosing diabetes

Random plasma glucose test

A blood sample for a random plasma glucose test can be 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 first taking a fasting sample of blood and then taking a very sweet drink containing 75g of glucose.

After 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, however, the result of the test is influenced by how high or low your blood glucose levels have tended to be over a period of 2 to 3 months.

Indications of diabetes or prediabetes are given under the following conditions:

• Normal: Below 42 mmol/mol (6.0%)
• Prediabetes: 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 you control your blood glucose levels as well as you can as too high sugar levels for long periods of time increases the risk of diabetes complications developing.

Diabetes complications are health problems which include:

• Kidney disease
• Nerve damage
• Retinal disease
• Heart disease
• Stroke

This list of problems may look scary but the main point to note is that the risk of these problems can be minimised through good blood glucose level control. Small improvements can make a big difference if you stay dedicated and maintain those improvements over most days.
