What Level Of Blood Sugar Is Dangerous
Higher blood sugar than normal is always a matter of concern. When should you become vigilant looking at your glucometer?
If you are a non-diabetic person then it is a basis of distress if your glucometer shows a number higher than 140mg/dl and in case of diabetic the range increases to 180 200 mg/dl. This condition is known as hyperglycemia and calls for the necessity to consult with a doctor.
Is testing blood sugar the only way to know your hyperglycemia? What would you do if you dont have glucometer at home?
Just be conscious of the following 7 symptoms:
In this condition, your body starts to burn fat to get energy as the cells dont get enough of it. This produces ketones causing the blood to be acidic and creates a life-threatening condition if left untreated.
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.
What Is High Blood Sugar
If your blood sugar levels are chronically higher than normal, then this is referred to as hyperglycaemia. This is a common issue for those suffering from diabetes. The condition can also affect pregnant women who have gestational diabetes and occasionally those who are severely ill .
Some of the symptoms of hyperglycaemia include:
- Increased thirst
- Blurred vision
- Issues with concentration and/or thinking
If severe hyperglycaemia is left untreated the condition can lead to organ and tissue damage as the excess glucose present in the body can make it difficult for the organs and cells to function correctly. The disorder can also impair the immune system response in the healing of wounds and cuts.
How Do I Measure Blood Sugar
If you have , 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.
What Is The Normal Range For Blood Sugar Levels And What Blood Sugar Level Constitutes A True Emergency
Dr. Horton answers the question: ‘Normal Range For Blood Sugar Levels?’
— Question:What is the normal range for blood sugar levels, and what blood sugar level constitutes a true emergency?
Answer:Now, in a normal individual we measure blood sugar under different circumstances. What we call fasting blood sugar or blood glucose levels is usually done six to eight hours after the last meal. So it’s most commonly done before breakfast in the morning; and the normal range there is 70 to 100 milligrams per deciliter.
Now when you eat a meal, blood sugar generally rises and in a normal individual it usually does not get above a 135 to 140 milligrams per deciliter. So there is a fairly narrow range of blood sugar throughout the entire day.
Now in our diabetic patients we see both low blood sugar levels that we call hypoglycemia, or elevated blood sugars, hyperglycemia. Now, if the blood sugar drops below about 60 or 65 milligrams per deciliter, people will generally get symptoms, which are some shakiness, feeling of hunger, maybe a little racing of the heart and they will usually be trenchant or if they eat something, it goes away right away. But if blood sugar drops below 50 and can get down as low as 40 or 30 or even 20, then there is a progressive loss of mental function and eventually unconsciousness and seizures. And of course that is very dangerous and a medical emergency.
How To Measure Blood Glucose
To quantify your metabolic health, youll need to measure blood glucose levels. Common tests include:
- Hemoglobin A1c : Provides a rough average blood glucose estimate of the past 2-3 months by measuring the amount of sugar stored in red blood cells.
- OGTT: The oral glucose tolerance test , administered in a lab, involves ingesting a sugary solution and measuring its impact on blood sugar levels
- Fasting blood glucose: Your blood glucose after an overnight fast of around 12 hours.
- Postprandial blood glucose: This is your post-meal blood glucose. It peaks 1 to 1.5 hours after eating.
Both fasting blood sugar and postprandial blood glucose are simple home blood tests, provided you have a glucose meter. Just prick your finger, insert the test strip, and record your result. If you have a Keto-Mojo blood glucose and ketone meter you can track your results over time with the free app.
Taking a blood sugar test is an ideal way to learn the effects of different foods on your body. Simply take a baseline reading , eat a particular food, then test 1 or 2 hours after eating. You might be surprised which foods spike your blood sugar. See this guide to testing for your and learn which foods elevate your glucose levels so you can avoid them.
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 and habits.
When Should I Be Measuring My Blood Sugar Levels Throughout The Day
According to the Diabetes Canada clinical practice guidelines, the schedules for testing blood sugar should be as follows:
|Situation||How often to check blood sugar|
|Type 1 diabetes using multiple daily insulin injections or using an insulin pump||Check four or more times per day|
|Type 2 diabetes, taking diabetes medication known to cause hypoglycemia||Check at times when symptoms of hypoglycemia occur, or at times when hypoglycemia has occurred previously|
|Type 2 diabetes, and meeting your blood sugar targets||Check once or twice per week, to ensure that your blood sugar targets are being met between A1C tests|
|Type 2 diabetes and not meeting your blood sugar targets|
How Does Freestyle Libre Work
The Freestyle Libre comes with a 14-day sensor that is worn on the upper arm. It lets you monitor your blood sugar levels anywhere and at any time. The sensor captures the glucose concentrationin the interstitial fluid every minute and records the glucose concentration every 15 minutes. All this data is stored in an eight-hour log. The set also comes with a user manual, a USB cable, and a power adapter.
What Are Abnormal Glucose Levels And Why Do They Matter
Why is it unhealthy for glucose levels to be too high or too low ?
Hyperglycemia refers to elevated blood glucose levels. This usually occurs because the body does not appropriately remove glucose from the blood; this can happen due to many complex reasons. Elevated glucose levels can damage blood vessels and nerves over time; this can then lead to problems in the eyes, kidneys, and heart, as well as numbness in the hands and feet. Very high levels can lead to coma and even death in some cases. People with fasting glucose levels higher than 100 mg/dl have impaired glucose tolerance and should speak with their healthcare provider.
Some people may think that to avoid all these issues, they should just keep their blood glucose levels as low as possible. If too high is bad, then low must be good, right? Not exactly. When glucose gets too low, its called hypoglycemia. The threshold for hypoglycemia is typically thought to be when glucose falls below 70 mg/dl. When this happens, the body may release epinephrine , the fight or flight hormone, which can lead to a fast heart rate, sweating, anxiety, blurry vision, and confusion, but also helps the body mobilize glucose into the blood. If blood glucose levels stay too low for too long, it can cause seizures, coma, and in very rare instances, death.
Sleeping Habits And Diabetes
According to research, insomnia affects how well you respond to insulin. People who sleep more than 9 hours each night also tend to have higher rates of diabetes. Sleep apnea can also increase someone’s probability of diabetes. Researchers have discovered that sleep-induced diabetes could raise the risk of other types of diabetes. More than 400 respondents reported how much sleep they get the night before.
Therefore it’s quite important to have a good night’s rest so you have enough strength throughout the day. Below you can find a few tips to create the perfect routine.
How Accurate Are A1c Tests
A1C levels rise well before the clinical onset of diabetes, making early diagnosis possible according to the 2017 Standards of Medical Care in Diabetes by the American Diabetes Association . Sometimes, however, in the early stages of diabetes, blood sugar levels are not high enough to show up as problematic. Testing environments, such as temperature in the lab, equipment used, and handling of samples, can affect the results; however, this is more common in the fasting plasma glucose and the OGTT than in the A1C. Strict quality controls and advancements in testing have made the A1C test more precise than in the past, according to the NIDDK. Doctors should be aware of laboratories that use an NGSP-certified method of testing for A1C levels. The NIDDK warns that blood samples taken at home or analyzed in a healthcare providers office should not be used for diagnosis.
There are some health conditions and situations that might skew the results of the test. These include:
- Blood loss or blood transfusions
Also, the test can be unreliable for people of African, Mediterranean, or Southeast Asian descent, people with a family member with sickle cell anemia, and those with thalassemia. For those who fall into these groups, a healthcare provider might suggest a different test or a specialized A1C.

Other Tips For Checking:
- With some meters, you can also use your forearm, thigh, or fleshy part of your hand.
- There are spring-loaded lancing devices that make sticking yourself less painful.
- If you use your fingertip, stick the side of your fingertip by your fingernail to avoid having sore spots on the frequently used part of your finger.
Random Blood Sugar Test
This measures your blood sugar at the time youre tested. You can take this test at any time and dont need to fast first. A blood sugar level of 200 mg/dL or higher indicates you have diabetes.
|140 mg/dL or below||N/A|

If your doctor thinks you have type 1 diabetes, your blood may also tested for autoantibodies that are often present in type 1 diabetes but not in type 2 diabetes. You may have your urine tested for ketones , which also indicate type 1 diabetes instead of type 2 diabetes.
What Is Considered A Normal Blood Sugar Level
The normal blood sugar level for a healthy adult should be less than 126 mg/dL or 6 mmol/L before fasting and meals, and below 200mg/dL two hours after meals.
If you are diabetic, then you should consult with your doctor in order for appropriate blood sugar level targets to be set based on the severity of your condition, medications taken and overall health status.
The below information describes what normal blood sugar levels are prior to and after meals and what the recommended HbA1c levels are for those with and without diabetes.
A HbA1c test determines your average level of blood glucose over the past two to three months. Red blood cells have a lifespan of roughly three months, and a HbA1c blood test measures the amount of glucose that has bound to them during this period.
A blood test to determine Haemoglobin A1c levels is often performed in those who have diabetes. These levels are a reflection of how well diabetes is being controlled.
What Is Blood Glucose Anyway
Blood glucose, or sugar, is sugar that is in your blood . It comes from the food that you eat foods that contain , such as bread, pasta and fruit are the main contributors to blood glucose. The cells in our bodies need glucose for energy and we all need energy to move, think, learn and breathe. The brain, which is the command center, uses about half of all the energy from glucose in the body.
Tests For Gestational Diabetes
Gestational diabetes is diagnosed using blood tests. Youll probably be tested between 24 and 28 weeks of pregnancy. If your risk is higher for getting gestational diabetes , your doctor may test you earlier. Blood sugar thats higher than normal early in your pregnancy may indicate you have type 1 or type 2 diabetes rather than gestational diabetes.
Checking My Blood Sugar Causes A Lot Of Pain In My Fingers Is There Something Else I Can Do
If you use your fingers to type at work on a daily basis, it can painful with frequent checks. Dont worry, this isnt how it has to be! There are definitely a few things you can try out.
The first and easiest thing to check is what your lancet device is set to. Start out with the lowest number on the dial and try it out. You should only need a tiny drop of blood for your test strip . If you dont see blood right away, try milking your finger by lightly squeezing it from your bottom knuckle to the tip if your finger.
Youll also want to make sure you are using a new lancet each time. A used needle not only increases the risk for infection, but it also can get dulled quickly resulting in a painful stick.
Where are you pricking yourself? Sticking it directly on top of the finger or on the pad of your finger is going to be more painful. Instead, try using the lancet device on the side-pad of your finger.
You can also use your lancet device on other areas of your body. These are known as alternate testing sites and include your upper forearm, thigh, palm, or abdomen. However, keep in mind, blood sugar reaches the fingertips quicker than any other AST. So youll have the most accurate reading from your fingers.
You can also try using a different lancet or monitoring devices. is a lancet device that is specifically meant to provide painless finger sticks. For a monitoring device, you might check if your insurance will cover a continuous glucose monitor like the Freestyle Libre.
Prevent Type 2 Diabetes
If your test results show you have prediabetes, ask your doctor or nurse if there is a lifestyle change program offered through the CDC-led National Diabetes Prevention Program in your community. You can also search for an online or in-person program. Having prediabetes puts you at greater risk for developing type 2 diabetes, but participating in the program can lower your risk by as much as 58% .
Do You Have To Fast For An A1c Blood Test
Unlike the fasting plasma glucose and the OGTT tests, there is no need to fast before having the A1C test. If A1C test results indicate a person has or might have diabetes, a healthcare provider might suggest one of these tests to confirm the results. Another test, the random plasma glucose test, which does not require fasting, can also be used. If the results are borderline or if the results of the different tests do not match, a doctor might suggest repeating the test in several weeks or months.
Normal Hba1c For Person Without Diabetes
For someone who does not have diabetes, a normal HbA1C level is below 5.7%. An A1C between 5.7% to 6.4% is indicative of prediabetes.
Its recommended that adults over the age of 45 or adults under 45 who are overweight and have one or more risk factors for diabetes have a baseline A1C checked. If the result is normal, the A1C should be checked every 3 years. If the result indicates prediabetes, the A1C should be checked every 1 to 2 years.
Why Is Blood Sugar Checking Important
If you live with diabetes, a blood sugar check is paramount to good control. Without knowing your blood glucose numbers, you cannot appropriately dose , treat a low blood sugar, eat a meal, or exercise with ease.
Think of a blood sugar check as a litmus test: the number isnt good or bad, it just gives a person with diabetes feedback on what they need to do next.
If a number is too high , its telling you to take some insulin or get some exercise, whereas if a number is too low, youll need to treat with sugar or some other form of glucose.
If your number is satisfactory, then you can proceed on with your day as planned.
Checking your blood sugar is also important to track long-term goals, like an hba1c test, and to see if youre reaching or even exceeding those goals.
Regularly checking your blood sugar also can give you feedback on whats working and whats not: maybe a particular food isnt working for your management goals, or a type of exercise, like yoga, has really helped to mellow out your blood sugar levels.
Its a good time to check in with yourself and calibrate your management to find what will work best for you, knowing that this can and will change over time.
What To Expect From Your Blood Sugar In The Morning
After an overnight fast, a normal blood sugar level is less than 100 milligrams per deciliter , according to the American Diabetes Association . But, according to Susan Spratt, MD, an endocrinologist and associate professor of medicine at Duke University School of Medicine, not everyone with type 1 or type 2 diabetes has to shoot for “normal” levels.
“If you’re young, the goal may be to get your fasting blood sugar levels to less than 120 mg/dL,” Dr. Spratt says. But if you’re older and have other health conditions, that number may be higher, she says.
The points out that not everyone will have the same blood sugar level goals. Instead, your endocrinologist or doctor will calculate your target number based on your age, how long you’ve had diabetes, whether you have health conditions like heart disease and other factors.
Keep in mind, too, that your fasting blood sugar levels can be too low. For example, a morning blood sugar reading below 70 mg/dL can indicate a , or low blood sugar.
Why Your A1c Matters
In a nutshell: your is one of the clearest indicators of your risk for developing diabetes complications like neuropathy , , , and severe infection in any part of your body that requires healing.
For instance, a small cut on your toe could become infected due to high blood sugars, struggle to heal, and become severe enough that the infection could lead to an amputation.
The general guidelines from the American Diabetes Association recommend an A1c at or below 7.0 percent for the best prevention of diabetes complications. Your risk of developing a diabetes complication continues to drop as your A1c drops closer to 6 percent.
Some people with diabetes aim for A1c levels in the 5s and lower especially those who follow strict low-carb diets like the ketogenic diet and the Bernstein diet. However, this hasnt been proven in research as especially necessary, nor is it reasonably achievable for the larger population of people with diabetes.
Its also important to remember that your blood sugar levels and your A1c are just information that tells you whether your body needs more or less of factors like insulin, other diabetes medications, changes in your nutrition, and changes in your exercise.
If you dont like the number youre seeing on your glucose meter or your A1c results, use that number as motivation to make changes in how you safely manage your diabetes in order to get different results.
What Should My Blood Sugar Be When I Wake Up
Checking your blood sugar first thing in the morning is important. In fact, fasting blood sugar readings really help you determine how to approach the rest of your day. You have to take steps considering how low or high your fasting blood sugar is, and understand how to set your morning target and what to do to achieve it. Let’s find out more about it.
Other Reasons For High Morning Blood Sugar Levels
If you continuously wake up with high blood sugar levels and haven’t eaten a bedtime snack the night before, your doctor may need to prescribe you more basal insulin , says Dr. Spratt.
However, if you typically eat a snack that contains carbohydrates before going to bed and don’t counteract it with rapid-acting insulin, your blood sugar levels may be higher in the morning as a result. Switch to a snack that won’t raise your blood sugar levels for example, a pairing of ham and cheese or a few bites of non-sweetened peanut butter, she says.
Lastly, if your blood sugar levels dip too low in the middle of the night, your body may release hormones that “rescue” you from dangerously low levels, according to the Cleveland Clinic. The result is that your liver releases stored glucose, causing your blood sugar levels to be higher than usual in the morning. This is called the Somogyi effect.
If you’re experiencing low blood sugar in the four to six hours after a meal, that’s a sign that your basal insulin dose is too high, says Dr. Spratt.
“A lot of people have lows of which they are not aware of,” she says. “They wake up and their blood sugar is high and assume they must need more insulin at night.” But, she explains, it’s important to check your blood sugar at 2 a.m. or 3 a.m. to make sure you aren’t experiencing a drop in glucose levels.
