What Is The Correct Reading For Blood Sugar

How To Choose A Blood Glucose Meter

There are many blood sugar meters to choose from, so start by thinking about what’s most important to you. Ask yourself a few questions.

• Are you concerned about accuracy? Make sure you’re using a meter and test strips that provide accurate results. Roche quality control processes ensure consistent accuracy. Find out more about our accuracy commitment.
• Do you use blood glucose results to dose insulin? The Accu-Chek Guide meter sends results directly to a smartphone app that includes an insulin calculator.5
• Do you feel like you’re always short on time? A system that syncs your data wirelessly, without manually entering results, can save time with every test. You may also want to consider a blood glucose meter that gives results quickly, makes it easier to handle test strips, doesn’t require coding, or simplifies lancing or dosing.
• Would you like to reduce the pain of testing? Choose a system with a lancing device specifically designed for comfort, such as the Accu-Chek FastClix lancing device. Precision-guided technology minimizes the lancet’s painful side to side motion and thin-gauge, bevel-cut lancets help ensure smoother entry. Plus, 11 customizable depth settings make it easier to get the right amount of blood the first time.
• Will you track results in the blood sugar meter, with an app or on a computer? Most blood sugar monitors have built-in memories, and many can beam or transfer data directly to your computer or an app on your smartphone, such as the mySugr app.

What Are Normal Blood Sugar Levels

You might want to measure your blood sugar before meals to get a baseline, and then two hours after your meal to measure your normal blood sugar level. Your doctor might also suggest measuring blood sugar before bed to be sure you have been eating well throughout the day and can go to sleep with peace of mind.

These are considered within the range of normal for blood sugar:

• Less than 140 mg/dl if you do not have diabetes.
• Less than 180 mg/dl if you have diabetes.

What Is A Normal Blood Sugar Level

The answer to the question what is a normal blood sugar level is as follows:

Fasting normal blood sugarNormal for person without diabetes: 7099 mg/dl Official ADA recommendation for someone with diabetes: 80130 mg/dl

Normal blood sugar 2 hours after mealsNormal for person without diabetes: Less than 140 mg/dl Official ADA recommendation for someone with diabetes: Less than 180 mg/dl

HbA1cNormal for person without diabetes: Less than 5.7%Official ADA recommendation for someone with diabetes: Less than 7.0%

What Is A Normal Glucose Level:

Diabetes Canada recommends an A1C of less than 7%.1 For blood glucose, the recommended target ranges are 4-7 mmol/L before meals and 5-10 mmol/L two hours after a meal. Its a good idea to sit down with your healthcare professional and discuss what target ranges are right for you. Things like your age, medications and time of day can impact your levels.

People With Gestational Diabetes

Gestational diabetes can occur during pregnancy. Often, it is a temporary condition, but it can lead to pregnancy complications.

The American Diabetes Association recommends that people with a diagnosis of gestational diabetes aim for blood sugar levels similar to those for people without diabetes, although individual targets may vary.

The ADA offers the following as a guideline:

• kidneys
• blood vessels

A wide range of complications can also result, such as slow wound healing and frequent infections. Other possible complications include:

Writing down your results will help you learn how things like meals, activity and medication affect your blood glucose. Is your glucose often low before breakfast? Or after you work out? With time, youll be able to recognize results that are out of range and learn how to spot any patterns.

Taking an active role in your diabetes care empowers you to make the right choices to reach your targets and better manage your diabetes.

What Is A Normal A1c

A person’s A1C is a measure of their average blood glucose levels over the previous 2 or 3 months, and it is measured through a blood test. A normal result for someone without diabetes or prediabetes would be below 5.7% an A1C between 5.7% and 6.4% indicates prediabetes and if your A1C is above 6.4% you would be diagnosed as having diabetes, according to the CDC .

Specifically, the A1C test is a measure of the percent of your red blood cells that have sugar-coated hemoglobin attached to them. The glucose that enters your bloodstream gets stuck to hemoglobin molecules on red blood cells. And the more glucose in your bloodstream , the more of your blood’s hemoglobin will be “sugar-coated,” and the higher your A1C will be, according to the CDC. As such, for people with diabetes , the number can give you and your doctors a sense of how well your sugars are being controlled.

The ADA recommends that most adults with diabetes should keep their A1C below 7% to reduce the risk of diabetes-related complications the goal is the generally the same for many children with diabetes Targets for the elderly with diabetes are slightly less stringent for the otherwise healthy with few coexisting chronic illnesses and intact cognitive function, the ADA recommends less than 7.5%, while those who don’t meet these requirements have a more lenient goal of below 8.0% to 8.5%.

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!

Symptoms Of Blood Blood Sugar Levels

Symptoms of blood sugar levels differ depending on if it is high or low. To determine which way the blood sugar have moved, the symptoms for each are typically:

If symptoms are left untreated, more extreme circumstances can happen such as fainting, weakness, disorientation, vomiting and dehydration. When you notice symptoms, usually more than one at one time, it is advised to see a doctor right away.

It is important to get the right treatment so that you can return to a healthy normal blood sugar level and inhibit it from occurring again.

Treatment methods vary from the severity of the blood sugar level, whether it is high or low and if the patient has existing medical conditions, such as diabetes. Here are ways in which blood sugar levels can be treated:

What Factors Affect Blood Sugar

You can guess that carbohydrate intake and insulin production are at least partly responsible for your blood sugar levels. But the list is much longer — almost every lifestyle choice you make can affect your blood sugar. Here’s just a partial list.

• Exercise can affect insulin sensitivity, leading to lower blood sugar for up to 48 hours.
• Alcohol intake increases insulin production, causing low blood sugar.
• Stress hormones like cortisol can raise blood sugar, because your body wants access to energy in order to escape what it perceives as a dangerous situation.
• Medications, especially statins and diuretics, can raise blood sugar. Statins are used to treat cholesterol, and diuretics for high blood pressure.
• Diet is a major player in blood sugar. Eating too many simple carbs at once can cause levels to skyrocket, while protein intake leads to a slower increase in blood sugar.
• Dehydration raises blood sugar, because with less water in your body the glucose concentration will be higher.

Other surprising factors can affect your blood sugar, like a sunburn or gum disease, so if you’re dealing with a blood sugar issue and can’t figure out what’s causing your spikes and dips, talk to a health care professional.

Cgm Studies In Nondiabetic Individuals

One study from 2009 entitled Reference Values for Continuous Glucose Monitoring in Chinese Subjects looked at the glucose levels of 434 healthy adults using CGM and found the following:

• On average, their daily glucose levels stayed between 70140 mg/dl for 93% of the day, with very small portions of the day spent above 140 mg/dl or below 70 mg/dl.
• Also, their mean 24-hour glucose levels were around 104 mg/dl
• 1-hour post-meal glucose values average 121-123 mg/dl for breakfast, lunch, and dinner
• 3-hour post-meal glucose values were around 97-114 mg/dl.
• Peak post-meal values appeared to be around 60 minutes after eating.
• Mean fasting glucose was 86 ± 7 mg/dl.
• Mean daytime glucose was 106 ± 11 mg/dl.
• Mean nighttime glucose was 99 ± 11 mg/dl.

A 2010 study, Variation of Interstitial Glucose Measurements Assessed by Continuous Glucose Monitors in Healthy, Nondiabetic Individuals, looked at a healthy population of 74 individuals that included children, adolescents, and adults during daily living using CGM. This research showed that:

• Glucose levels stayed between 71-120 mg/dl for 91% of the day.
• Levels were lower than 70 mg/dl for 1.7% of the time and greater than 140 mg/dl, only 0.4% of the time.
• Mean 24-hour glucose was 98 ± 10 mg/dl.
• Mean fasting glucose of 86 ± 8 mg/dl.

Compared to the first study mentioned, these healthy, nondiabetic individuals appeared to have a tighter range of glucose, spending the vast majority of the 24-hour period between 71-120 mg/dl.

Factors That Can Affect Blood Sugar Levels

If you have prediabetes or diabetes, you may have insulin resistance or an inability to produce insulin. This means your body has difficulty regulating blood sugar levels on its own.

Its a delicate balance to maintain, so the following list can help you familiarize yourself with factors that can cause your blood glucose levels to go up or down.

Understand Your Blood Glucose Test Results

Get the most out of your blood glucose test results know what they mean, when to test, and how to respond.

Daily glucose tests, routine A1C lab tests thats a lot of numbers to make sense of, which can be intimidating. Try to see them as your body talking to you. Its telling you if there are things that throw your blood glucose levels off, when this is happening, and if you need to do something about it. Knowing what your numbers mean can help you better manage your diabetes and have more days feeling at your best.

Low Blood Sugar Level Causes

Most low blood sugar level causes are preventable and are caused due to a persons lifestyle and diet habits. Low blood sugar is common among diabetic patients who take medications to increase insulin levels.

All of the above causes are risk factors that may or may not be able to be inhibited. They are important to be aware of and act accordingly to keep yourself from getting a too high or too low blood sugar level.

If a person has medical, lifestyle or diet habits that cause irregular blood sugar levels, symptoms will begin to develop along with the drop or spike in blood sugar, and are as follows:

Managing Diabetes Over Age 65

Low blood sugar is called hypoglycemia. It’s defined as a level lower than 70 mg/dL . Symptoms include:

• Shakiness, nervousness, or anxiety
• Clumsiness
• Seizures

Hypoglycemia is common in older adults with diabetes. This may be due to other health concerns, such as other chronic illnesses, malnutrition, or multiple medications. The risk of diabetes complications increases with age.

Hypoglycemia can also result from taking too much diabetes medication. Overtreatment is common in older adults.

Researchers say hypoglycemia is likely underreported in those over 65. That may be because they don’t always have symptoms. Also, cognitive impairment may cause difficulties communicating about symptoms with caregivers.

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.

Whats Considered A Normal Glucose Level

Your doctor will likely test your blood glucose levels as a screening test for diabetes during a standard yearly check-up. Additionally, many people track their glucose at home with an over-the-counter finger-prick test. When you check blood glucose , either at a doctors office or with a home finger stick glucose monitor, the results are in milligrams of glucose per deciliter of blood.

One of the most common glucose measurements is fasting plasma glucose or fasting blood glucose , and its found by checking blood glucose levels after not having any calories at least eight hours before the test. According to the American Diabetes Association , people can be classified into three categories depending on their fasting plasma glucose levels: normal, prediabetes, and diabetes. To be considered normal, fasting glucose must be under 100 mg/dl.

Of note, CGM devices measure interstitial glucose levels compared to blood/plasma glucose levels measured in the FPG tests. While interstitial glucose and blood/plasma glucose levels correlate highly, they are not precisely the same, and diagnoses are not made from interstitial measurements.

Below is a summary overview of data about 24-hour glucose trends in nondiabetic individuals wearing CGM to gain a better understanding of whats normal.

Take Your Insulin As Prescribed

High blood sugar occurs when your body has too little insulin, or your body cant use insulin properly. Administering insulin can bring your blood sugar levels down.

Talk to your doctor about how much rapid-acting insulin you should administer when your blood sugar is high.

You may want to check your blood sugar about 1530 minutes after taking insulin to make sure your blood sugar is going down and that its not dropping too low.

How Can I Treat Low Blood Sugar

If youve had low blood sugar without feeling or noticing symptoms , you may need to check your blood sugar more often to see if its low and treat it. Driving with low blood sugar can be dangerous, so be sure to check your blood sugar before you get behind the wheel.

Carry supplies for treating low blood sugar with you. If you feel shaky, sweaty, or very hungry or have other symptoms, check your blood sugar. Even if you dont have symptoms but think you may have low blood sugar, check it. If your blood sugar is lower than 70 mg/dL, do one of the following immediately:

• Take four glucose tablets.
• Drink four ounces of fruit juice.
• Drink four ounces of regular soda, not diet soda.
• Eat four pieces of hard candy.

Wait for 15 minutes and then check your blood sugar again. Do one of the above treatments again until your blood sugar is 70 mg/dL or above and eat a snack if your next meal is an hour or more away. If you have problems with low blood sugar, ask your doctor if your treatment plan needs to be changed.

Stick To Your Medication And Insulin Regimen

Skipping a dose of medication or insulin can be harmful to your body and increase your blood sugar levels.

Its important to stick to your treatment plan and follow your doctors instructions for taking your medication.

Summary

Healthful lifestyle habits can help people manage their blood sugar levels over the long term, such as eating a balanced diet, getting regular exercise, staying hydrated, and getting good sleep.
