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.

Low blood sugar levels, normal blood sugar levels and high blood sugar levels chart.

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.

Use this tool to convert blood sugar values.

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.

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.

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.

  1. Hello, was just wondering as to what is normal blood sugar level for non diabetic as opposed to normal blood sugar level for diabetic (if there is such a thing as \”normal\” blood sugar level for diabetic). I hope my question make sense…
    Dennis

  2. Any help,

    I went for a CBC my Random Blood Glucose is 12.4 mg/dl. The doctor told me to do another test that will be my HBA1C and the result is 6.2% what is that means? any help

    Thank you…

  3. this is sanjeev.. i dint had food for 30 hours . in between i had only 2.5 ltr water only. after 30 hours i checked my sugar level its 122.. is it normal blood sugar?

  4. MY BLOOD SUGAR WAS 129 THIS MORNING SOME TIMES IN THE 30S ONCE IN A WHILE BELOW 100 THE REST OF THE DAY SEEMS TO BE OK MY 90 DAY AVE. GLUCOSE IS 136 SHOULD I BE CONCERNED?

  5. I am 66 years old and had total gatrectomy done for NHL in stomach in the year 2000. My blodd sugar readings are eratic and range from 140 (fasting) to 300 (random). I do take insulin (long acting) once in the morning and Glucophage 750 mg once in the evening as per doctor\’s advice. My surgeon who did the total gastrectomy says that upto 200 is ok for my age. Am I a type 1 or 2?

  6. Is it possible to get any graphical method of say weekly or some times 10 days irregular days with NORMAL graphical line.Soas to check and be precautionary by diabetic patient itself.

  7. sir,my child is 2 years old , his serum glucose level fasting for 8 hours is 96 mg / dl its normal or i must follow him. Tank you

  8. 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.

  9. I almost put myself at risk, luckily I went for check up early and my blood sugar levels was 12.9 and when go back after one week it was 8.2. I thank my Dr. because he advised me well to stop drinking fizz drinks, do regular exercise, eat more fruits and vegetables and have a balance diet and I followed the instructions. Now it’s at normal

  10. Hi was wondering could you tell me what the normal blood test should read it’s just my 4 yr old son has autism and recently he had to have a lot of blood tests done for medical and metabolic testing the result is as follows ph 7.378 pco2 5.09kpa po2 11.24kpa hit 38.3 percent na’137.6mmol/l k’3.97mmol/ l ca2+1.187mmol/l glu 5.9mmol/l lac1.8mmol/l uhb12.5g/dl be _277 mmol/l chco2 22.0 mmo/l so2 97.0percent O2 he 95.5 percent Cohb0.9 percent methb0.6 percent hub 3.0 percent and Bill value below 3.0 mg /dl are these ok or should I be worried haven’t to go back to drs fir 2 months

  11. 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.

  12. 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.

  13. My uncle who is 65 yes old having diabetes. His sugar level during fasting is 148 mg/dl and after 2 hours from mealbit is 258 mg/DL. Please suggest what to do?

  14. 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?!

  15. 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

  16. My normal blood sugar reading is between 102 to 110 before breakfast my goal is to keep it from going any higher 126 in the morning before breakfast is high to me .I am type 2 diabetic. I watches what I eat and exercise when I can walking is good

  17. sir i check my blood sugar level in the morning after 2hr of taking meal. it showing 103 mg/dl. what it show. i am 23yr old. & my father has diabetes problem. he give me blood in my child hood when i admitted in hospital that time i was 2 yrs old. is their possibility that i also have diabetes problem.
    please help me, guided me.

    in the hope of favorable response

    thank you.

  18. Just around the borderline on both BP and Blood Sugar. Learning how to use natural means (diet and exercise) to keep both within normal ranges.

  19. sir now a days my blood suger level is high after meal my suger in night 183 and after drink tea is 153 and i do not eat sweet and drink then my suger level is high my age is just 24 my 6 month beby and my family heredity blood suger

  20. 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.
    🙂

    • Karon
      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
      Nigel

  21. 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

  22. I need an solution for decreasing sugar level from 190mg/dl
    to safe zone…please help me ….
    age of patient is 50years..
    thank you alot..

  23. 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.

  24. SORY ABOUT SPELING I NEVE COOD.i was told by doctors 9 muths ago I had tipy 2 and givin metermothin 500mg 4 times a day ime falling asleep in the afternoon as ime finding it hard to keep awake can eney one help.

  25. if my fathers (age 57)all check up values are normal only sugar value before lunch is153 and after lunch is 307.is it possible?or report is wrong.should i do check up once again.

  26. my mean blood sugar value for fasting is 134.5 and that of random is 156.5
    however my HbA1c is 6.4
    kindly guide me whether i am pre-diabetic or diabetic ?

  27. Well I’m a tattoo artist and also overweight I’m 5’6 and weigh 250 lbs been heavy my whole life and have been noticing I’ve been more thirsty and also urinating more often . I don’t have medical coverage so I decided to go but a glucose meter and check levels today I haven’t ate in 8 hrs and took test this morning and it said 232mg so now I’m a lil worried and hopeing if I can start eating better and exercise more I can bring it down some being a tattoo artist I’m sitting down all the time all day drawing designs and tattooing for sometimes 8 hrs or more any advice to helpaybe with diet and or exercises would be helpful thanks for any reply …

  28. 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.

  29. 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.

  30. Hi there
    my sugar level in the early morning is 6.1 to 6.8 just in the early morning . During the day and after lunch in 2 hours never above 6 .What does that mean .
    Any thing to worry about
    Is it high # if so
    What can i do to avoid the high # in the morning.
    Thanks

  31. 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.

    • 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

      • Thanks for that. I know it recommends that you eat fruit, but my mother’s blood sugar only got under control after she stopped eating fruit?

        • 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.

  32. 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?

    • 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.

  33. I am 48y I test my blood levels at morning some times it is 89 some normaly 95 99 some times it is 103 after meals 1 h it 134 155 165 but after 2 h it is 100 107 some times it is 118 not lot do I consider my self normal or predicated I ckecked my levels for 3 months accumulating it was 5.2 and now after some diet and exercise it is 4.3

  34. When I got first diagnosed, my BG was 828. I was normal but because I lost lots of weight and felt too thirsty and urinate frequently, I went to see a doctor. Then he put me in medication. I am too glad that I did not end up in coma.

  35. So – one doctor tells me I am prediabetic with fasting level 5.8 and another says no way! yet….I know I am sugar sensitive….what do I do???

  36. Dears Site Organizer,
    The content of the site you provided with the considerable information is so well arranged to benefit the users , specially those who are seeking the knowledge to check themselves with the diabetics particulars to be helped accordingly.

    I suggest to develop your site to be linked with the new diabetic’s Instruments as I hope the testing Unites will be produced which does not need to prick fingers for the Blood testing .

    Over all I really enjoyed to go through the site and the data furnished . Thank You.

  37. 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.

  38. 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.

  39. My mom has type 2 diabetes, and has a lot of trouble regulating her levels, she is 79
    I thought as I was testing hers I’d do mine. I just eaten about 10 mins and my results were 9.0 is that high I suffer with high blood pressure and I’m 53.

  40. I have been a constant dull headache on my forehead for the past 3 weeks with intermittent nausea. My doctor ordered a CBC and thyroid test. Everything came back WNL except my glucose was 64. This was a random glucose. I had eaten breakfast 3 hrs before the test. My doctor is not concerned with my result. Could the low blood sugar be causing my symptoms? I am otherwise a healthy 34 feamle.

  41. it would be highly appreciated if you could give me a chart including glucose amount of various food and vegetables.my fasting blood sugar test is 109 and I really afraid of that .

  42. I went to doctor, had tetanus shot, 9 days later ended up in emergency room, spent 2 days in ICU with blood sugar level of 1700. Now diagnosed with type 2. No one in family has diabetes. Could vaccines do this?

  43. Hi ,My mother went for random blood glucose level test…. Result says its 234mg/dL …. May I knw,wat is her present condition???? Is it controllable???My mom’s age is 50yrs…. Plz do rply asap 🙁

  44. 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.

  45. Hallow,my sugar level 4hours after eating was 3.9 and in the morning before eating was 4.5 ,is there with problem with me?kindly advice

    • You are way above the normal range.What is your weight and what do you think is a good weight if you could be? What kind of foods do you normally eat? Fat in the cells is the main contributer to type 2 diabetes.Your doctor should put you on Metforman,the best most widely used diabetic med in the world.Undoubtly need to lose weight, change your eating habits more walking etc. what ever it takes to get diabetes under control. Please do something about it. Don

  46. This portion of information on blood glucose is very helpful and positive. Keep up the good work on health tips. God bless you.

  47. My daughter has been having all the symptoms of low blood sugar. So I borrowed my mother in laws meter to check when she has an episode. Fasting it is 95. Is that normal for a 10 year old girl first thing in the morning?

  48. 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?

  49. My 2 1/2 year old who is potty trained recently started having random accidents. I noticed an increase in his daily times he urinates. His school noticed today also that he voided 6 times at school today and had two accidents. This prompted me to check his sugar once we got home and his random sugar today was 180. Not sure if I am worried over nothing but I am gonna get his urine checked in the morning. His dad is a type 2 diabetic. Also thought about a UTI.

  50. my grandsons fasting bloodsugar was 3.8 , is this a concern and should we check with Dr.
    Both his maternal grandmothers have type 1 diabetes

  51. sir my age is 28 and i examined the blood sugar level .my fasting level is 80 and after meal(postmeal) 150. may it indicates dibetics case.

    • 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…..

  52. I was diagnosed with Type2 Diabetes in May and the result was 94 ,I have since had another Test and have been told that it has come down to 47,I have been following a strict Diet of no Sugar and trying to not have Carbohydrates although have had Brown Pasta and Seeded Wholemeal Bread,I eat meat,chicken and Fish ,Salads,Green Vegetables non acidic Fruits,I drink water Soya Milk and try to have regular medium meals and I have lost weight and I am now within the weight for my height and I exercise everyday and try not to sit about for long but I do not see the levels shown here in the form I have been given and the Nurse did not mention having to take Medication which I was trying so hard to avoid so are my readings ok?

  53. I am recently diagnosed with Diabetes with Fasting Glucose test of 7.9 before suggary drink and 16.3 at 2 hours after. But, since then I started working out at the gym and changed to a low carb diet. Now it reads 6.2 before meals and 6.8 at 2 hours after meals. Should i take the precribed medication. I haven’t taken yet.

  54. i am new at this diabetes and i don’t undestand diabetes.early in the morning my blood sugar sometime in the 90’s may be 100 some mornings.and during the day 122 never 200. need a site i can go to help undestand diabetes and a chart to go by.

    • 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.

  55. I have been transformed by your information….may God direct you the more so that we can benefit more from your rich information

  56. my sugar level some time low some time high is going from fasting 5.5-6.8 and after eating 1h is 8.5 and after 3 h is going back 5.8 thanks

  57. Is there a problem brewing if glucose levels are below 60 more than 4 times a month? What should the range be during the day, 100 to 160? How long does the blood sugar have to be below say 140 each day? I have type II diabetes.

  58. Very informative – thank you so much
    I have type 1 diabetes and I find this information and
    chart very helpful.
