What is Normal Blood Sugar Level

The blood sugar concentration or blood glucose level is the amount of glucose (sugar) present in the blood of a human or an animal.

The body naturally tightly regulates blood glucose levels (with the help of insulin that is secreted by pancreas) as a part of metabolic homeostasis.

If blood sugar levels are either increased or decreased by a greater margin than expected this might indicate a medical condition.

What is blood sugar?

What does it mean when someone refers to blood sugar level in your body? Blood sugar level (or blood sugar concentration) is the amount of glucose (a source of energy) present in your blood at any given time.
A normal blood glucose level for a healthy person is somewhere between 72 mg/dL (3.8 to 4 mmol/L) and 108 mg/dL (5.8 to 6 mmol/L). It, of course, depends on every individual alone.

Typically blood sugar level in humans is around 72 mg/dL (or 4 mmol/L). After a meal the blood sugar level may increase temporarily up to 140 mg/dL (7.8 mmol/L). This is normal.

Note: mg/dL and mmol/L are units of measure. mg/dL is mostly used in USA whereas mmol/L is mostly used in EU and other parts of the world. For easier conversion try our mg/dL mmol/L conversion tool.

checking blood sugar level A blood sugar level between 72 mg/dL (4 mmol/L) and 108 mg/dL (6 mmol/L) is considered normal for a healthy adult.

What is normal blood sugar level?

Adults
A normal blood sugar level is between 72 mg/dL and 108 mg/dL (4 to 6 mmol/L) for a healthy person.

The concentration of glucose in the blood of a healthy person in the morning on an empty stomach is between 68 mg/dL and 108 mg/dL (3.8 and 6.0 mmol/L). Two hours after consuming foods or drinks rich in carbohydrates, the values are usually between 120 and 140 mg/dL (6.7 and 7.8 mmol/L).

Children
For children up to 6 years of age desired blood sugar level before eating is between 100 mg/dL (5.5 mmol/L) and 180 mg/dL (10 mmol/L). Before sleep values should be between 110 mg/dL (6.1 mmol/L) and 200 mg/dL (11.1 mmol/L).

For children between the age of 6 and 12, before eating, blood sugar levels should be between 90 mg/dL (5 mmol/L) and 180 mg/dL (10 mmol/L). Before sleep values should be between 100 mg/dL (5.5 mmol/L) and 180 mg/dL (10 mmol/L).

Children aged 13 to 19 should expect similar readings than those of adults.

Blood sugar levels chart

Blood sugar levels rise and drop during the day. This is normal. However, dramatic fluctuations in your blood glucose levels may indicate problems.

Dramatic changes of blood sugar levels have significant physical symptoms and will increase your risk of diabetes-related complications.

What is considered low blood sugar level?

When your blood sugar level drops below 70 mg/dL (3,9 mmol/L) this means you have a low level of blood sugar. The usual symptoms of low blood sugar levels are:

  • hunger,
  • sweating,
  • restlessness,
  • faltering speech,
  • confusion,
  • tremor,
  • difficulty in concentration,
  • drowsiness,
  • headache,
  • visual disturbances…
  • Symptoms may vary – different people might experience different symptoms. In some cases symptoms can even remain unrecognized (unconscious hypoglycemia).

    What is considered high blood sugar level?

    Chronically high blood sugar (diabetes) is caused by a number of abnormalities in the body, one of them being the affected vascular walls of small and large arteries (diabetic micro-and macro-angiopathy) in a process called atherosclerosis.

    We can say that a blood sugar level is high if we measure glucose level and get the following values – more than 110 mg/dL (6.1 mmol/L) on an empty stomach or at any time more than 200 mg/dL (11.1 mmol/L).

    measuring blood sugar level Source: www.theguardian.com
    If measured blood sugar level is high you should consult your personal doctor! High values of blood sugar may indicate diabetes.

    High blood sugar levels affect the arteries throughout the body, especially the organs which have the richest blood circulation: heart, brain, kidney, senses, nerves and other organs.

    If the high blood sugar is associated with disturbances in lipid metabolism (blood fat), the abnormalities are more intense. Diabetes is among the risk factors for major non-communicable diseases: cardiovascular (coronary) disease, cerebral vascular disease and peripheral vascular diseases.

    Diabetes symptoms

    Typical symptoms of high blood sugar levels (diabetes) are thirst, frequent urination and unexpected weight loss. Sometimes a patient may also experience the following:

  • impaired vision,
  • itching skin,
  • fatigue,
  • increased appetite,
  • skin infections,
  • feeling of dizziness,
  • heavy dehydration.
  • Type 1 diabetes symptoms are severe and last for a short time before the disease is diagnosed. Type 2 diabetes symptoms appear slowly and are usually unrecognizable or nearly absent.

    How to check blood sugar

    There are basically two main tests which are conducted to determine whether someone has diabetes.

    Impaired fasting glycemia test
    When being tested for diabetes by a impaired fasting glycemia test, blood sugar levels will normally be taken after around eight hours of fasting.

    Impaired glucose tolerance test
    An impaired glucose tolerance test involves taking a concentrated amount of glucose and then measuring blood sugar levels after two hours.

    In a healthy person, a normal blood glucose level is between 72 mg/dL (4 mmol/L) and 108 mg/dL (6 mmol/L). Read on how to check blood sugar values.

    For checking your blood sugar level, you will need:

    Medical alcohol to clean the skin where you will prick your finger, a sterile tool to prick your finger, some test strips and a glucose meter to read the test strip.

    You can easily buy blood glucose tester via below form:

    Expected blood sugar level values:
    Glucose mg/dL or mmol/L level Value
    less than 110 mg/dL or 6 mmol/L on an empty stomach normal value
    between 110 mg/dL or 6.1 mmol/L and 125 mg/dL or 6.9 mmol/L on an empty stomach limit value
    more than 125 mg/dL or 7.0 mmol/L on an empty stomach possible diabetes
    more than 198 mg/dL or 11.0 mmol/L anytime possible diabetes

    Can diabetes be cured?

    At this time there is no known official case of cured diabetes.

    The fact is that with Diabetes type 1 body’s cells that produce insulin are destroyed. These cells cannot be regrown or replaced. You need to use insulin injections to control your blood sugar levels.

    With type 2 diabetes your body does not use insulin properly (also known as insulin resistance). Over the time a patient’s condition worsens as body cannot make enough insulin to keep blood glucose at normal levels.

    With exercise and proper diet you can control your diabetes and live a normal life. Read more about diet for people with diabetes and blood type diet.

    Refer to this article for more information on how brown fat tissue may help control your disease or even revert it! No hoax – scientifically proven!
    Brown fat protects against diabetes and obesity in humans

    How to lower blood sugar level?

    A patient with diabetes is at a 5 times greater risk of developing cardiovascular disease than patient without diabetes. One third of all cardiovascular diseases also affect people with diabetes.

    Three quarters of diabetics die from cardiovascular disease. Women with diabetes have a 4 times greater risk of death from cardiovascular disease. People suffering from diabetes usually have high cholesterol levels as well.

    Disturbances in the metabolism of blood sugar levels are mainly the consequence of heredity (diabetes in the family), age (over 40), poor diet, excessive body weight (obesity) and physical inactivity. Disturbances in the metabolism of blood sugar were present in 20% of adult Europeans during 2002-2005 a study showed.

    or

    RECOMMENDATIONS to decrease elevated blood sugar:
    Blood sugar level is determined in the fasting state. In a healthy person, a normal blood glucose level is less than 108 mg/dL or 6 mmol/L on an empty stomach. By measuring values of blood sugar, we can say that there are 3 options:

    • normal blood sugar level (the blood glucose level is normal on an empty stomach),
    • disruption of glycemia (blood glucose in the blood on an empty stomach is increased to a maximum value between 110 and 124 mg/dL (6.1 and 6.9 mmol/L),
    • diabetes (elevated blood sugar levels to 126 mg/dL / 7.0 mmol/L or more).
    People with high blood sugar levels can lower their blood sugar levels by maintaining normal body weight, eating healthy and by physical activity. This way you might prevent or delay disease and enhance your health and physical performance.

    What can you do to lower the chance of developing diabetes:

    • lose weight – be fit,
    • sleep more, be rested. Read this article on what to do if you cannot sleep.
    • have a healthy diet (read how should a diabetic diet look like) with as many vegetables and fruits, a lot of fiber, consume less calories, less fat, less alcoholic beverages and no simple sugars,
    • workout at least 30 minutes per day.

      if your blood sugar is 180 or more, uh, I would go see a doctor. Definitely cut out the sweets, and especially the sodas but really you need to be controlling carb intake because carbs are sugar.

      Chromium will lower blood sugar. It is the only thing I have found that will. Do not use it though, unless you are monitoring your blood sugar levels and are already familiar with what those levels are.

      I was hospitalized for 6 days, brought in with blood sugar of 14 and body temp 91. I have been taking my readings every morning since I have been released (about 2 weeks) my Blood has been back in forth from 60 to 89 but this morning I didn’t wake up til 11:30 am and it was 138! This is on an empty stomach. Is this just as bad as being dreadfully low? We still have no answers as of why it was at 14.

      My wife 69 years old diabetic for 27 years.from 9 a.m. To midnight her Blood sugar is in Hyperglycemia range, mostly in the range 250/350 mg/DL.After midnight her Blood Sugar level drops at a very high rate and by 3/4 a.m. It drops to Hypoglycemia range,mostly in the range 40/80 mg/DL. After 5 a.m. It starts reversing and by 7 a.m. It shows her Blood Sugar level in normal range say 100/110 mg/DL.
      This is inspite of the fact that she is not given any medicine after lunch and no food after 10p.m.
      Can anybody tell from where insulin comes after midnight and from where sugar comes after 5 a.m.?

        blood sugars rise at night because of cortisol levels. The high sugars at night are common. The numbers you mentioned during the day are very high. Speak with your doctor. You might need to check your blood glucose before meals and get insulin coverage for meals. She needs a doctor.

      I recently checked my blood sugar out of curiosity and it was 49 mg/dL. I felt completely normal though. I’m 17 years old, 4’11 and 105 lbs. I have had symptoms of hypoglycemia in the past (dizziness, increased heart rate, fatigue), but overall, I’m a very healthy individual. My mother has low blood sugar levels, as well, but she’s never experienced this. I must also add that my father is a diabetic (which explains why i have a blood glucose tester) and diabetes runs in my family. I don’t have diabetes, however. So… can anyone explain what’s going on with my blood sugar?!

      A fasting reading this morning I did was 83 then I ate and checked again after and hour or so it was 110. Then checked again at random it was 96. My doc suggested I might be hypoglycemic because of some of the particular symptoms I’ve had. I’m not sure if my sugar just runs low because most of the time I don’t feel the symptoms. But when I do I get scared out of my wits. I don’t scare easily so I know this is nothing to be messed with. Idk know what my normal sugar level is being that I’m 6’6 148lbs

      Nigel Smith, look at what you are eating in the morning and try something with a bit more fibre. This should take a bit longer for the sugar to get into your blood. Sometimes with exercise, glucagon is produced by your liver if your blood sugar is too low and this will increase the test result. Only you know what you have eaten so diet is important. Speak to your doctor for diet advice.
      🙂

        Thank you. In the morning I tend to just have porridge oats with skimmed milk. My higher readings tend to be pre breakfast although the levels are coming down. Regrettably I have found that diabetes nurses have just told me that diabetes is a function of previous smoking ( I never have) and I am over weight ( I’m not) so I am lacking confidence in their ability to view me as an individual and advise accordingly.
        Thank you for your guidance. Gratefully received

      Excellent site
      Being new to this, and someone who does not do things by halves, I have been tracking my glucose levels some 4 or 5 times a day. It appears that c1 hour after waking my results are the highest, 7.5-9 mol/l. Rest of day always below 7 with an average for the day of 6.5-7mmol/l. I eat healthily and am not overweight , go to gym etc
      How can I bring down my morning reading as this will reduce the average to closer to 6.25/6.5?
      Are my results a problem?
      Thanks
      Nigel

      I got a fasting blood glucose test done for my 10 year old son. The result was 106mg/dl. As per your website, it states that fasting levels till 180 for his age group are fine whereas other websites like Wikipedia and Mayo clinic state that 100-125 is pre-diabetic. Would you please explain why is there so much of a difference and which one should I actually believe in? I am really worried. Please help.

      We randomly test my 4 year old daughters glucose and it has never been under 7 mmol/L. Yesterday morning it was 7.8 so we didn’t give her anything else to eat but some cinamon water to drink, and this morning on an empty stomach the reading was 7.1 mmol/ L We gave her some plain oatmeal after the test. Is there reason for concern. My family has a strong history of diabetes and I had gestational diabetes with her brother and sister, but not when I was pregnant with her.

      My 6 year old son was recently diagnosed as pre-diabetic. He is 4 ft tall and weighs 48lbs so as you can tell he is not over weight in fact his height and weight are perfectly proportionate to each other. Any way the doctor just called me and told me that his blood glucose levels are high but his insulin levels are normal. The only information she gave me was to change his diet and get the levels checked again in three months. Is that a normal response or is there something else I need to be doing. I have no ideal what the numbers said and I’m just really confused.

      Thanks for the info, but now I’m confused. I went to a healthy heart clinic and now my doctor wants me to have another test. I have an appointment for a HBA1C test, my doctor said it’s just routine (I am not diabetic). I assume they think I could be diabetic (my mother is type 2). I did a fasting test which came out at 6.1, but then I did another test after 2 hours from eating (apple pie & ice cream), this came out at 12.9. What does this mean? Looking at what I’m reading on websites, it means I’m diabetic, but then I’m not? Please can anyone explain.

      • Healthiack April 24, 2014 at 8:35 am - Reply

        Your values may indicate pre-diabetes. Given the fact that your mother has type 2 diabetes you are under greater risk to develop diabetes type 2 as well (although this relation has never been confirmed by scientists). But we cannot diagnose you, only your personal doctor can do that.
        What you can do is to change your diet and delay the possible development of this disease by following some simple diet rules. Read more here: http://healthiack.com/diets/diet-for-people-with-diabetes

            A person with diabetes can enjoy all fruits – be it pineapple or cherries, apples or figs …even citrus fruits and grapes. The only limitation is the amount of fruits eaten. This amount is different for every person. Your mother’s case is somehow odd as fruit is recommended food for diabetics.

      The following two lines from your table do not make sense. Postprandial blood glucose levels should be higher not lower than random blood sugar levels.

      about 70-125 mg/dl (3.9-6.9 mmol/l) Normal random blood sugar
      about 70-111 mg/dl (3.9-6.2 mmol/l) Normal postprandial blood sugar

      Are they switched? Or does one have an error?

      • Healthiack April 23, 2014 at 2:28 pm - Reply

        Thank you for pointing that out. There was a slight typo in the chart.
        Normal postprandial blood sugar level is between 70 and 199 mg/dl or 3.9 to 10.9 mmol/l where 199 mg/dl (10.9 mmol/l) is a borderline value and may already indicate diabetes.

      hi, i was diagnosed with type 2 diabeties, and have not been taking my medication regularly. I did my HBA1C about 3 weeks back, and the result was 14mmol/l. Well, now i have been constantly on medication and its currently in the range of 5-8mmol/l. This is for before food (took the reading for before breakfast and dinner, but not lunch). Yes i tracked them.

      But my question is, after been on “sugar” for quite some time, and now in the process of lowering the blood sugar level, i hav efound myself to be giddy, like really bad headaches but not migraines. Sometimes as though i feel that what i am seeing is actually a dream, that its not real.

      And when that happens, i check my blood pressure is normal, and my glucose reading will be between 5 to 5.5 mmol/l.

      Is this normal or should be expected by me during this phase of “recovery”? Is there anyone that could advise me please?
      Really appreciate it.

      Btw, i dont feel thirsty or inceased urination. Although my eyesight is not sharp as it used to be.

      As a nurse and parent of a type 1 diabetic child, your numbers are way off. Nothing under a 4.0 is normal. Anything under 4.0 requires fast acting sugar. Low blood sugar can cause serious damage. Please be more responsible with your “facts”.
      If anyone is in doubt, please seek treatment. Especially if there is increased thirst, urination and weight loss. Vomiting and lethargy are a huge indication to seek ambulatory treatment if combined with the other symptoms.

      Your figures are not consistent – sometimes you say that up to 5.5 is a ‘normal’ fasting glucose (true) and then about 2 sentences later you say that it is anything up to 6.1 (no – that’s impaired fasting glycaemia) but you state at least 3 different numbers for ‘normal’ fasting. Also I think your figures for children are wildly off.

      I have hypoglycemic symptoms that’s why my doctor gave me a glucometer to check my blood sugar regularly. I have a question : In the morning on a empty stomach my blood sugar was at 4.7mmol on the glucometer. two hours after a tuna sandwich I went at 6.5mmol and later in the day after a meal I was at 6.4 mmol. I noticed that if I eat a good quality meal with veggies, lean meat and whole wheat pastas my mmol are around 6.4-6.5 and if I eat something cheap like from a fastfood or something like a sandwich without proper ingredients my blood sugar stays around 4.9mmol. Is this normal?

      I need to eat regularly and healty which I started doing. Are my readings alright?

        fasting level is normal…… and you don’t say how long post meal or what you ate. Although it is said that most people doing rise much above 140 after meals, so yours is hardly way out of whack. Also, it is better to have an A1C test… because it tests your blood sugar over a longer course…. spot checking doesn’t give you anything but a snapshot in time. Obviously if you are a diabetic, yeah, test yourself especially when you are trying to find out if there’s foods you should avoid…..

        Consult your doctor for more information.
        Diabetes is characterized as chronically elevated blood glucose (blood sugar) which your body needs for energy. This occurs whether because the pancreas is not providing sufficient amount of insulin (diabetes type I) or target tissues are not responding to insulin (type II diabetes). Diabetes is more likely to develop in families with known diabetes history.

        Blood sugar level chart:
        less than 6.1 (140) on an empty stomach means normal value, between 6.1 (140) and 6.9 (169) on an empty stomach indicates a limit value, more than 7.0 (172) on an empty stomach could mean possible diabetes and more than 11.0 (260) anytime usually indicates diabetes.
