How To Check Blood Sugar Levels

What Happens During A Blood Glucose Test

A health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. For some types of glucose blood tests, you will need to drink a sugary drink before your blood is drawn.

If you have diabetes, your health care provider may recommend a kit to monitor your blood sugar at home. Most kits include a device to prick your finger . You will use this to collect a drop of blood for testing. There are some newer kits available that dont require pricking your finger. For more information on at-home test kits, talk to your health care provider.

How Do Carbs Affect Blood Sugar

Carbs in food make your blood sugar levels go higher after you eat them than when you eat proteins or fats. You can still eat carbs if you have diabetes. The amount you can have and stay in your target blood sugar range depends on your age, weight, activity level, and other factors. Counting carbs in foods and drinks is an important tool for managing blood sugar levels. Make sure to talk to your health care team about the best carb goals for you.

Causes Of Blood Sugar Levels

Whilst the liver and muscles produce some glucose, most comes from the foods we eat. Food and drinks that are high in carbohydrates are most impactful on blood sugar level. What we eat provides us most of the nutrients our body needs and sometimes, does not need. That is not to say that food is a major cause of blood sugar level increasing or decreasing too dramatically. 

Typically, if a person has health conditions or poor nutrition, this will lead to a spike or decline in blood sugar level. The causes differ from high to low blood sugar levels and are as follows:

What If I Have Trouble Getting To My Blood Sugar Goals

There may be times when you have trouble reaching your blood sugar goals. This does not mean that you have failed. It means that you and your health care team should see if changes are needed. Call your health care team if your blood sugar is often too high or too low. Taking action will help you be healthy today and in the future.

How To Test Your Blood Sugar At Home

Follow these steps:

 

Manage Your Carb Intake

Your body breaks carbs down into sugars , and then insulin helps your body use and store sugar for energy.

When you eat too many carbs or have insulin-function problems, this process fails, and blood glucose levels can rise.

However, there are several things you can do about this.

The American Diabetes Association recommends managing carb intake by counting carbs and being aware of how many you need .

Some studies find that these methods can also help you plan your meals appropriately, further improving blood sugar management (

The recommended daily intake of fiber is about 25 grams for women and 38 grams for men. Thats about 14 grams for every 1,000 calories .

Summary

Eating plenty of fiber can help with blood sugar management. Soluble dietary fiber is the most effective.

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!

How Do I Check My Blood Sugar

You use a blood glucose meter to check your blood sugar. This device uses a small drop of blood from your finger to measure your blood sugar level. You can get the meter and supplies in a drug store or by mail.

Read the directions that come with your meter to learn how to check your blood sugar. Your health care team also can show you how to use your meter. Write the date, time, and result of the test in your blood sugar record. Take your blood sugar record and meter to each visit and talk about your results with your health care team.

Drink Water And Stay Hydrated

Drinking enough water may help you keep your blood sugar levels within healthy limits.

In addition to preventing dehydration, it helps your kidneys flush out the excess sugar through urine.

One observational study showed that those who drank more water had a lower risk for developing high blood sugar levels (

).

Its important to monitor your waistline, as its perhaps the most crucial weight-related factor for estimating your diabetes risk.

A measurement of more than 35 inches for women and more than 40 inches for men is associated with an increased risk of developing insulin resistance, high blood sugar levels, and type 2 diabetes .

Having a healthy waist measurement may even be more important than your overall weight .

Summary

Keeping a moderate weight and waistline will help you maintain normal blood sugar levels and decrease your risk for developing diabetes.

How Frequently Should I Measure My Blood Sugar

The Centre for Health Protection in Hong Kong   advises you to measure your 2-4 times per week at various times during the day . You should monitor your blood sugar more often if:

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:

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

What Else Can I Do To Help Manage My Blood Sugar Levels

Eating a healthy diet with plenty of fruit and vegetables, maintaining a healthy weight, and getting regular physical activity can all help. Other tips include:

• Keep track of your blood sugar levels to see what makes them go up or down.
• Eat at regular times, and dont skip meals.
• Choose foods lower in calories, saturated fat, trans fat, sugar, and salt.
• Track your food, drink, and physical activity.
• Drink water instead of juice or soda.
• Limit alcoholic drinks.
• For a sweet treat, choose fruit.
• Control your food portions .

Symptoms Of Diabetes That May Prompt An A1c Test

As mentioned by the , a doctor may recommend an A1C test if a person shows signs of poor glucose control, diabetes, or prediabetes.

Warning signs can include:

• increased urination, especially at night
• increased hunger
• numbness or tingling in the hands or feet
• slow healing sores

• long-term use of glucocorticoids, antipsychotics, and certain medications for

Know Your Blood Sugar

Blood sugar is the amount of sugar in your blood at a given time. It’s important to check your blood sugar level, because it will:

• determine if you have a high or low blood sugar level at a given time
• show you how your lifestyle and medication affect your blood sugar levels
• help you and your diabetes health-care team make lifestyle and medication changes to improve your blood sugar levels

What Time Of Day Should I Test

Recommendations for the best time of day to test your blood sugar depend on your medicine, mealtimes, and blood sugar control. Your doctor may provide a chart that outlines when to check your blood sugar and what level you should target. Your doctor may also suggest different goals, depending on your situation.

The chart may look something like this:

*Depends on the size of the meal and the amount of insulin in your medicine

Will I Need To Do Anything To Prepare For The Test

You will probably need to fast for eight hours before the test. If you are pregnant and are being checked for gestational diabetes:

• You will drink a sugary liquid one hour before your blood is drawn.
• You won’t need to fast for this test.
• If your results show higher than normal blood glucose levels, you may need another test, which requires fasting.

Talk to your health provider about specific preparations needed for your glucose test.

Managing Blood Sugar When Youre Ill

When you get sick, your blood sugar levels may fluctuate and become unpredictable.

If you’re sick, it’s very important that you:

• drink plenty of water or sugar-free fluids
• check your blood sugar levels more often than usual
• take 15 grams of carbohydrate every hour if you are not able to follow your usual meal plan
• replace food with fluids that contain sugar if you can’t eat solid food
• continue to take your insulin or other diabetes medication;

If you have a cold or flu and want to use a cold remedy or cough syrup, ask your pharmacist to help you make a good choice. Many cold remedies and cough syrups contain sugar, so try to pick sugar-free products.

As an extra precaution, you should always check with your health-care team about guidelines for insulin adjustment or medication changes during an illness.

Using A Blood Glucose Meter

You can check your blood sugar at home, at work, and anywhere else. Your diabetes team will help you choose a blood glucose meter. A meter measures the amount of glucose in a tiny drop of blood. Youll use a device called a lancet to draw a drop of blood. Put the strip in the meter first. Then touch the test strip to the drop of blood. The meter then gives you a number that tells you the level of your blood sugar.

Treatment For High Blood Sugar Levels

For those with high blood sugar levels, it is vital to keep track of your blood sugars at home on a daily basis. This can be done with a glucose meter. These test monitors are often provided to diabetic patients so that they can manage their blood sugar levels at home everyday. They are available to purchase online if you are non-diabetic but wish to check on your levels regularly for safety.

Diabetic patients can be prescribed medications to help with insulin levels when their blood sugar is high. Those with type 1 diabetes will be prescribed medication which needs to be taken several times daily. This type of diabetes has no cure but can be managed with the right medication. 

Those with type 2 diabetes or gestational diabetes can treat their high blood sugar with a change in diet or exercise. A healthier balanced diet is usually advised and sometimes, insulin medication is also prescribed if the blood sugar level becomes abnormally higher than the high reading for diabetic patients.

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.

Types Of Blood Sugar Tests

You can take a blood sugar test two ways. People who are monitoring or managing their diabetes prick their finger using a glucometer for daily testing. The other method is drawing blood.

Blood samples are generally used to screen for diabetes. Your doctor will order a fasting blood sugar test. This test measures your blood sugar levels, or a glycosylated hemoglobin, also called a hemoglobin A1C test. The results of this test reflect your blood sugar levels over the previous 90 days. The results will show if you have prediabetes or diabetes and can monitor how your diabetes is controlled.

When and how often you should test your blood sugar depends on the type of diabetes you have and your treatment.

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:

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 Do I Pay For These Tests And Supplies

Medicare, Medicaid and most private insurance plans pay for the A1C test and some of the cost of supplies for checking your blood sugar. Check your plan or ask your health care team for help finding low cost or free supplies. Ask your health care team what to do if you run out of test strips.

What Are Blood Sugar Levels

Blood sugar levels, also known as blood glucose level, is the level of sugar/glucose present in the blood. Glucose is a simple version of sugar which comes from the food we eat. Therefore, the more food you consume with high sugar levels over a period of time, will typically increase your blood sugar level. 

Glucose comes from the foods we eat and its sugar content. When a person consumes a food with high sugar content, that is turned into glucose. The glucose is then absorbed into the bloodstream with the support of insulin. This is then distributed between the bodys cells and used as energy.

Foods high in glucose include most carbohydrates and a handful of proteins and fats. Most foods contain glucose as it is simply a natural sugar that occurs in most dietary forms. However, it is carbohydrates that contain the most sugar and 100% of it turns into glucose, through the process mentioned above, once consumed. The concentration of glucose present in the blood will determine your blood sugar level.

Here is a quick video explaining Blood sugar levels chart :

Your blood sugar level can either be low, normal or high. Depending on what you eat and health conditions, it will vary from person to person. Here is a breakdown of how your blood sugar works and how low or high blood sugar levels happens:

Why Do I Need To Know My Blood Sugar Numbers

Your blood sugar numbers show how well your diabetes is managed. And managing your diabetes means that you have less chance of having serious health problems, such as kidney disease and vision loss.

As you check your blood sugar, you can see what makes your numbers go up and down. For example, you may see that when you are stressed or eat certain foods, your numbers go up. And, you may see that when you take your medicine and are active, your numbers go down. This information lets you know what is working for you and what needs to change.

What Are Target Blood Sugar Levels For People With Diabetes

A target is something that you aim for or try to reach. Your health care team may also use the term goal. People with diabetes have blood sugar targets that they try to reach at different times of the day. These targets are:

• Right before your meal: 80 to 130
• Two hours after the start of the meal: Below 180

Talk with your health care team about what blood sugar numbers are right for you.

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
• 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.

How Do I Check

People with diabetes check their blood sugar levels by poking their fingertips and using a blood glucose meter or a continuous glucose monitor  to measure the blood glucose level at that moment. Read on to find out how to use a blood glucose meter. To find out more about CGMs, start by talking to your doctor.

Follow These Steps To Check Your Blood Sugar:

Write all of your blood sugar readings on the blood sugar record log. Write them down even if they do not match with the columns. Some people use an app on their smart phone to record their blood sugars.

How Do I Measure Blood Sugar

If you have diabetes, you probably already keep a watchful eye on your blood sugar through the use of a continuous glucose monitor or a blood sugar meter . Blood sugar measurement is also typically included in routine lab work for people without diabetes — your physician will usually order a glycated hemoglobin test, which measures your average blood sugar over the past two to three months.

Say your A1C test comes back with no sign of diabetes — constantly measuring your blood sugar can still be helpful. For instance, some people experiment with using a CGM to see how their body responds to different types of food. However, it’s good to note that this is a fairly cost-intensive way of figuring out your nutrition, and writing down a food diary that includes how you felt after each meal will also help you figure out what to eat.

Check out these blood sugar monitors if you’re looking for recommendations on how to keep track of your levels at home.

Blood Sugar Level Chart By Age

Blood sugar levels tend to rise with age due to an increase in insulin resistance and decrease in insulin sensitivity. In one study by the National Health Institute , each extra decade of age was linked to a 2.7 mg/dl increase in fasting glucose, and a 4.5 mg/dl increase in 2-hour post-prandial glucose levels.

Tools And Supplies Needed To Check Blood Sugar

There are a few different supplies needed to safely and accurately test blood sugar.

Your blood sugar testing kit probably came with control solution as well. This is not needed for actual testing, but rather for ensuring glucose meter accuracy. By checking your glucose meter with control solution, you can be sure that your results are reliable. Using control solution to check the first test strip in every new bottle of strips will provide you with the peace of mind that comes from knowing you can trust your supplies to be accurate!
