What Is The Normal Blood Sugar Range For Adults

Beyond Normal Goals: Whats An Optimal Glucose Level And Why Does It Matter

Exact numbers for what is considered optimal glucose levels to strive for while using CGM to achieve your best health are not definitively established; this is a question that is individual-specific and should be discussed with your healthcare provider. With that said, research shows that there is an increased risk of health problems as fasting glucose increases, even if it stays within the normal range, making finding your optimal glucose levels all the more important.

While the International Diabetes Federation and other research studies have shown that a post-meal glucose spike should be less than 140 mg/dL in a nondiabetic individual, this does not determine what value for a post-meal glucose elevation is truly optimal for your health. All that number tells us is that in nondiabetics doing an oral glucose tolerance test, researchers found that these individuals rarely get above a glucose value of 140 mg/dL after meals.

So, while this number may represent a proposed upper limit of whats normal, it may not indicate what will serve you best from a health perspective. Many people may likely do better at lower post-meal glucose levels. Similarly, while the ADA states that a fasting glucose less than 100 mg/dL is normal, it does not indicate what value is optimal for health.

The following is a summary of insights from our review of research. You should consult with your doctor before setting any glucose targets or changing dietary and lifestyle habits.

Diabetes Is Diagnosed By Any One Of The Following:

Sometimes you may have symptoms of fatigue, excessive urination or thirst, or unplanned weight loss. However, often people have no symptoms of high blood glucose and find a diabetes diagnosis surprising.

Other Severe Symptoms Of Hyperglycaemia Include:

• Nerve damage
• Kidney damage
• Blood vessel damage

Mild hyperglycaemia, depending on the cause, will not typically require medical treatment. Most people with this condition can lower their blood sugar levels sufficiently through dietary and lifestyle changes.

Those with type 1 diabetes will require the administration of insulin , while those with type 2 diabetes will often use a combination of injectable and oral medications , although some may also require insulin.

Adjusting Blood Sugar Target Ranges

There are some times when it is appropriate to adjust the blood sugar target ranges for a person with diabetes. Targets can be adjusted due to the age of the individual.

A 92 year old with diabetes, for example, would not be looking at the long term complications of diabetes as much as a younger person would. Therefore, the target range should be adjusted related to the advanced age of the patient.

Mainly, there is an adjustment in the target range for the A1C. In the elderly with diabetes who are not looking at the long-term complications, the A1C target can be set at less than 8 percent.

Other factors, such as other health conditions, stress, illness, how long a person has had diabetes for, and lifestyle habits and activity levels may be considered when setting an A1C target, as well as a fasting, pre-meal, and post-meal blood sugar target.

For example, a patient who is not getting good control of blood sugars, and having frequent readings in the 200-300 mg/dl level may be told to keep their fasting and pre-meal blood sugar in the 80-140 mg/dl range, and post-meal blood sugar less than 200 mg/dl. As the patient improves self-management, the target ranges can be tapered down to the usual ranges.

What Causes Blood Sugar To Be High

Many things can cause high blood sugar , including being sick, being stressed, eating more than planned, and not giving yourself enough insulin. Over time, high blood sugar can lead to long-term, serious health problems. Symptoms of high blood sugar include:

• Feeling very tired.
• Having blurry vision.
• Needing to urinate more often.

If you get sick, your blood sugar can be hard to manage. You may not be able to eat or drink as much as usual, which can affect blood sugar levels. If youre ill and your blood sugar is 240 mg/dL or above, use an over-the-counter ketone test kit to check your urine for ketones and call your doctor if your ketones are high. High ketones can be an early sign of diabetic ketoacidosis, which is a medical emergency and needs to be treated immediately.

Determining The Right A1c Goal For You

Just because a normal blood sugar range of 70 to 130 mg/dL is considered the healthiest doesnt necessarily mean thats the appropriate goal range for you especially if you have type 1 diabetes, or take insulin as a person with type 2 diabetes.

The reason this may not be the right goal for you is that extremely tight blood sugar management in people taking insulin can potentially lead to frequent low blood sugars which can be dangerous.

Achieving extremely tight blood sugar management, like a range of 70 to 130 mg/dL, also often requires a strict nutrition plan, more frequent than usual blood sugar monitoring, precise medication management, and most importantly, years of experience studying your own blood sugar levels.

Different Levels And What They Mean

The ranges of safe levels of blood glucose depend on factors such as what time of day it is and when you last ate. Safe levels of blood sugar are high enough to supply your organs with the sugar they need, but low enough to prevent symptoms of hyperglycemia or complications of diabetes which follow the National Institute of Diabetes and Digestive and Kidney Diseases guides. Dangerous levels of blood glucose are outside of this range.

The target levels can also vary if you have diabetes. For example, if you are diabetic and are monitoring your blood sugar, you might get a reading of 65 mg/dl. That is considered to be mild hypoglycemia, and you would be wise to eat 15 grams of fast-acting carbohydrates and retest your blood sugar in 15 minutes.;

If you were not diabetic, you probably would not know that your sugar was low because you would not test and because you would not symptoms, and you would not act.

That is fine because your body is capable, under normal circumstances, of raising your blood glucose to healthy levels when needed, even if you have not eaten. It is important to keep them in control to help prevent issues like heart disease or nerve damage.

How To Reduce Blood Sugar

You can take steps to reach your blood sugar goals as soon as you find out that it is high. This is how to reduce blood sugar if you have a single high reading that may be dangerous:

• Ask your doctor what to do if you missed a dose of insulin or another diabetes medication
• Ask your doctor if your medication types and doses are still appropriate for you
• Drink water to dilute the sugar
• Exercise for 15 minutes
• Eat a small protein snack, such as a hard-boiled egg, ½ ounce of peanuts or pistachios or other nuts, ½ cup of beans, or ½ cup of plain yogurt or cottage cheese

If you have chronically high blood sugar in prediabetes or diabetes, you can follow this treatment plan:

• Exercise regularly, assuming your doctor approves it
• Lose weight if you are overweight or obese
• Eat a higher proportion of vegetables, whole grains, lean proteins, healthy fats, and fruit
• Limit sugary foods and beverages, fried foods, refined starches, and processed and fatty red meats
• Beware of starchy vegetables such as sweet potatoes, which can spike your blood sugar. Check out our guide of which veggies to avoid!

What Is The Treatment For Type 2 Diabetes

Treatment for this type of diabetes can include:

• Diabetic eating plan

• Foot problems such as wounds that don’t heal, loss of feeling, or pins and needles sensations
• Neuropathy or nerve pain especially in the legs and feet
• Sexual issues such as erectile dysfunction, inability to orgasm or feel full sensation
• Urinary frequency
• Unusual odor to urine

If you have diabetes, you have a higher risk of heart disease and heart attack. Because of this, it is important to control cholesterol and high blood pressure in addition to blood sugar. The good news is that all of these diseases are responsive to healthy lifestyle changes.

Target Blood Sugar Levels For People With Diabetes

People with diabetes have difficulty creating or using enough insulin, which is the hormone that helps convert glucose into energy. Although there is no universal blood sugar chart for everyone with diabetes, clinical organizations like the ADA and American Association of Clinical Endocrinologists offer guidelines on target blood sugar levels as a starting point.

Healthcare providers typically tailor normal blood sugar target ranges to an individual diabetes care plan. This includes considering your:

• Age

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 Federations target ranges for people without diabetes is stated.

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.

How To Measure Blood Sugar Levels

There are two main ways to check your blood sugar levels:;

Type 1 diabetics, along with some type 2 diabetics, who require insulin medication, must check their blood sugar at least four times per day, says Mathioudakis. Typically, this should be done before a meal, one to two hours after a meal, and at bedtime.;

The timing of these measurements can help determine how much insulin to use. For example, it can be important to use more insulin after a high-sugar meal, or to avoid falling into hypoglycemia while you’re sleeping.;

To check your blood sugar at home, you should use blood glucose tests, such as a glucose meter or continuous glucose monitor . Both devices measure blood sugar with the unit mg/dL, which means a milligram of sugar per deciliter of blood.;

If you don’t have diabetes, but you may be at risk, your doctor might have you take an A1C test during a yearly check-up. This test reports results as a percentage; the higher the percentage, the higher your blood sugar has been in the past three months. Those with diabetes should get an A1C test at least twice a year and sometimes every three months.;

Normal Fasting Blood Sugar For Person Without Diabetes

A normal fasting blood glucose for someone who does not have diabetes ranges from 70 to 99 mg/dl. The American Diabetes Association recommends a routine screening for type 2 diabetes starting at age 45. If the results are normal, the screening should be repeated every 3 years.

If have diabetes risk factors, which include being overweight or obese, having a family history of type 2 diabetes, having a history of gestational diabetes, or being of a certain race/ethnicity , you should be screened for diabetes sooner than age 45.

Children and adolescents who have diabetes symptoms or who are overweight and have a family history of type 2 diabetes, are of African American, Latino, Asian American, Native American or Pacific Islander descent, who have signs of prediabetes or a mother who had gestational diabetes should be tested beginning at age 10 and then every 3 years thereafter.

A fasting blood sugar of 100 to 125 mg/dl is indicative of prediabetes, which is a condition where blood sugar levels are above normal but not high enough to be considered diabetes. Prediabetes is a risk factor for type 2 diabetes, heart disease and stroke. Its managed by lifestyle changes and, in some cases, medication.

How To Save On The Freestyle Libre With Singlecare

If you dont have it yourself, you probably know at least one person living with diabetes. More than 30 million people in the U.S. alone have the condition. Which means youre likely familiar with the hassle of having to monitor glucose levels at all times. The process involves pricking your finger tip with a needle to test a drop of bloodouch!;

When you have diabetes, its crucial to make sure its under control by testing your glucose levels often, based on your doctors recommendation. Luckily, for those who are sensitive to it or just tired of the repetition, there is an easier way: the Freestyle Libre, an FDA-approved glucose monitoring system that works as an alternative to the finger stick.;

Can Type 2 Diabetes Be Prevented

A healthy lifestyle can prevent almost all cases of type 2 diabetes. A large research study called the Diabetes Prevention Program, found that people who made intensive lifestyle changes including diet and exercise reduced their risk of developing diabetes by 58%. Those over 60 years old seemed to experience extra benefit; they reduced their risk by 71%. In comparison, people who were given the drug metformin for diabetes prevention only reduced their risk by 31%.

Diagnosing Prediabetes Type 2 And Type 1 Diabetes

Depending on which country or medical organization you ask, the qualifying numbers for normal versus prediabetes versus diagnosed type 1 or type 2 diabetes can vary slightly. The following blood sugar and A1c the general results are used to diagnosed prediabetes and diabetes according to sources including the American Diabetes Association and Diabetes UK:;;

Prediabetes

• HbA1c: 5.7 to 6.4 percent
• Fasting: 100 to 125 mg/dL
• 2 hours after a meal: 140 mg/dL to 199 mg/dL

Type 1 or 2 diabetes

• HbA1c: 6.5 percent or higher
• Fasting: 126 mg/dL or higher
• 2 hours after a meal: 200 mg/dL or higher

Please note: Type 1 diabetes tends to develop very quickly which means that by the time symptoms are felt, blood sugar levels are generally well above 200 mg/dL all the time. For many, symptoms come on so quickly they are dismissed as the lingering flu or another seemingly ordinary virus.

By the time blood sugar levels are tested, many newly diagnosed type 1 patients will see levels above 400 mg/dL or higher. If you do suspect that you or a loved-one has type 1 diabetes, visit your primary care or urgent care immediately and ask for a urine test to measure ketones in addition to testing blood sugar levels and A1c.

Normal Range Of Blood Sugar Levels

The normal range of sugar levels in the blood for elderly who are not diabetes sufferers before fasting is 72 to 99 mg/dL. However, the sugar levels for the people treated for type 1 or 2 diabetes before fasting scale from 80 -130 mg/dL. According to the American Diabetes Association, seniors recommended blood glucose levels must be lower than 180 mg/dL after two hours of taking meals. Additionally, the normal blood glucose range before and after eating the meals should be between 80-130 mg/dL.;

For the individuals who are not diabetic patients, the higher range for blood sugar level begins at 140 mg/dL. Whereas, for those individuals who are diabetic patients, the range for the high level of blood sugar starts at 180 mg/dL.

The 411 On A1c: Normal A1c Levels And 15 Ways To Lower High A1c

The hemoglobin A1C test is the closest thing to a diabetes scorecard you can find. Whether someone has had diabetes mellitus for years or if they have just been diagnosed, they have probably heard about this test. Unlike blood sugar meters people use at home, the A1C measures an average blood sugar level over the past several months by analyzing how many of a patients hemoglobin cells have glucose attached to them. The test results keep track of how well a person is managing his or her diabetes.;

Normal Blood Sugar Levels In Adults With Diabetes

This post will explain Fasting blood sugar level. Diabetes is specified as an illness in which the body has an impaired ability to either produce or react to the hormonal agent insulin. Characters with type 1 diabetes have a pancreas that prepares not manufacture insulin. Somebody with type 2 diabetes have cells in the organisation that are resistant to insulin and have a pancreas that slows or stops producing sufficient insulin levels . Both types of diabetes can result in irregular glucose levels.

Why Is My A1c High

As blood sugar level rises, so do A1C levels. A high A1C indicates that blood sugar control is not optimal. This in itself is not an emergency, but it gives your healthcare provider a picture of how blood glucose has, or has not, been controlled, says Dr. Williams.;

Poor diabetes control or a need for medication adjustments might cause higher A1C. Diet changes, daily exercise, or medication adjustments might quickly lower A1C. Because Type 2 diabetes is a progressive disease, adjustments to ones treatment might be a part of the process of controlling diabetes. Poor diabetes control does not always mean a patient is doing something wrong. But there are other reasons why levels might be high.;

As previously mentioned, other health conditions can cause skewed results. These include kidney disease, anemia, liver disease, asplenia, blood loss, hypothyroidism, uremia, and sickle cell anemia. Other factors that might lead to a high A1C level include increased age, pregnancy, and gestational diabetes.
