  2. Manny

    Hi im 300lbs
    Ive been checking my blood sugar every morning for the past 3 days
    Its always under 100 (fasting )
    But ive been feeling pins and needles in my feet
    They went away when i stopped drinking or eating any type of sugar (candy/soda etc)
    Do u guys think im pre diabetic or full blown diabetic?

    • Tammy Schrader

      Get your A1C tested and also an insulin test. You need to fast for both of these tests.

  10. Siddh

    I had my sugar checked and it is 450 after eating afternoon meal,
    I am a 39 years of age, am I need to take medical assistance ?

    • Maria

      First question is did you take your diabetes medications before your meal? If yes then how long ago did you eat? If you ate two or more hours ago then your sugar is staying too high for longer periods. You should call your physician. Now before you call him/her review what and how much you ate and what type of activities you did since you ate: all of these details are the biggest part of your diabetes management puzzle.
      My own Example: If I eat two slices of pizza or a medium sized bowl of pasta my sugar will shoot up into the 350 + range and stay there for hours past the meal and despite my insulins. I then have to take a few more units of my fast acting insulin to bring it down. I test every hour until it\’s within my target range then once more to assure it is not in a freefall.
      If I eat 8-9 oz. (yes that much) of lightly spiced salmon, a good salad (no meat, dairy or croutons, light on the light dressing, and a small -medium bowl of cooked broccoli, green beans or brussel sprouts with only a dash of salt my sugar will stay on target (130 or less one hour after my meal) I get to enjoy a good sized meal, and healthy delicious food.
      Your physician will instruct you on how much insulin to take but you must use caution or your sugar will bottom out so stay on top of testing. Good Luck and Healthy Eating!

    • Pradeep kumar Panigrahi

      Please rush to see a doctor.

    • Aariz

      Yes asap

  11. David Mercer

    I\’ve been type 2 now for about 10 years (I\’m 63 years of age). About 3 months ago I got the results of my 3/4 months average check. T\’was s touch on the high side, despite 1,000mg Metformin a day so the nurse doubled the dose.
    I began to show symptpms of lactic acidosis so the Dr stopped the Med. I was ok, but now my bg readings have crept up from a stable 7 – 7.5 to this morning at 11.2.
    Should I be concerned. Complications are that I am recovering from cancer (down to one lung), and am particularly susceptible to infections. The COPD doesn\’t help much, either.
    Words of wisdom would be received very gratefully.

  15. Michael

    I am 32, slightly overweight, with no history of diabetes, and not on any medications. I am on a moderate diet of about 2300 kCal daily, with only moderate physical activity on most days. Today about 3 hours after a big breakfast of serial and milk, followed by a bit of standing around, I felt weak and shaky. I checked my blood sugar, and it was 53 mg/dL. I ate some nuts, which helped me to feel a bit better. Is this common? What sorts of culprits should I be looking for? Until yesterday, the lowest measurement I had recorded was 81 (a few years ago). Normally my measurements are between ~80 and ~130 (usually taken after breakfast).

  22. radheshyam


  23. ajay sharma

    I am 42 years old and after tea my sugar level 127 . is it any problem or not?

    • Michael McKinley

      Ajay, That depends on what you had with your tea and how you take your tea.

      If you had any carbs with your tea (cake, biscuit/cookie, bread) or if you take it with sugar/honey then a quick spike might be normal. If you take your tea unsweetened and had nothing accompanying it, and it had been a few hours since you had and sugar or carbs, then that might indicate you have a sustained elevated level.

      In either case it is in the low end of the concern range so it is not something I would panic over, but something to discuss with your doctor the next time you visit.

  24. Manik Hossain

    Hi, I am 32 years old and I have blood sugar level between 120 to 150 everyday . As per doctor suggestion I am take medicine metformina daily one pcs 850mg.
    What should i do for bring down as Normal level .

    • Michael McKinley

      Manik, I am no doctor…so anything your doctor has told you to do is likely a better choice than what I offer. The two biggest things we as sufferers can do it watch out diets and get more exercise.

      I do not pretend to know what you eat or what your physical condition or exercise routine is, but here are a few tips.

      Food: Remove as many carbs (carbohydrates) as you can. This includes rice and grains. Whole grains and brown rice are better than processed ones. White \”sticky\” rice, and anything from flour like bread, crackers, and anything with a crust. Watch starchy vegetables like corn, potatoes, peas. Another thing that is overlooked is fruits…many are high in sugar and thus carbs. Stick to vegetables and low fatty proteins as much as possible.

      Exercise: Even walking more will give you an improvement. Better yet work on fast walking to raise your heartrate and maintain it as long as you can. Track your progress, it is heartening to see the duration and even speed go up….and you should notice that the blood sugar levels start to go down.

  25. Ranjeet

    Today I want to check my blood sugar morning after eating 113 and after breakfast 130.
    What to do?

  26. Vasanth

    Hi Frnds my bs level after fasting is 480 I am 30 years old ..Wat can I do pls help me

    • Michael McKinley

      Vasanth, If you are still checking this forum and seeing numbers like that, go to a doctor NOW. Not next week, not tomorrow….now that is approaching extreme hazard area.

      Please do this for your loved ones if not for yourself.

  27. Manik

    • raul brammin

      HI Saravanti

      Although all doctors may say it won\’t affect, but honestly, I would suggest in your lunch reduce your carbs …

      just as a whole , eat much more veggies and meat… and lower the amount of rice and chapati you eat…

      high sugars affect in small ways or big .. absolute truth !

    • Amanda

      I am not a dr. or nurse by no means but have a lot of medical background with my family being nurses. To me it sounds like you are hypoglycemic. I only believe that because I have pre-diabetic hypoglycemia. But you should still considering consulting you Primary Care Physician (PCP).

    I am a 39 year old female I weigh 107 pounds 5’7 my glucose normally runs at the highest 115 but I work at a nursing home and had a nurse check it tonight it was 166 is this too high?

  49. kayla

    I was diagnosed with type 2 diabetes about a week ago after having a FBG= 7.2 and a BG=11.0 after the OGTT.

    My bed time glucose levels have been around 6.2 and my morning levels are around 5.6-5.8 is this an okay level? I was diagnosed with type 2 diabetes about a week ago after having a FBG= 7.2 and a BG=11.0 after the OGTT

    I also had a very weird reading today. I ate then went for a walk and found my BG at 3.9

    I ate a serving of taco chips and salsa 30min after the reading of 3.9 ( i wanted to test the effect of the chips)
    1 hour after chips BG= 6.8
    2 hrs after chips BG= 8.9

    I have never had a reading this his yet….my highest has been 6.6. I ate dinner after the 8.9 reading (had hamburger with no bun) and within 2 hours BG= 5.3 .

    After the 5.3 reading I had a glass of wine and a small piece of cake and did not see a spike. Is this a normal reaction? does this mean tortilla chips spike my blood sugar and wine helps lower it?

  50. Maria


    I’ve just had a glucose fasting result is 7.9 mmol/L reading.
    What action I need to do? I’m Start aerobic exercise every 30 mins. and walking 1 hr. Do I need to take a prescription from Doctor for diabetes borderline?.

    • ray

      Hi Maria, just keep track of the food you eat. Get the glycemic index food list so you can track the carbs which will help you lower your blood sugar.

  51. Amy

    I checked my mom sugar level 174 fasting this morning what precaution needed to be taken for her.Please let me know .iam worried about her .
    I checked mine is 67 fasting .is it dangerous if you have low sugar level.Please let me know.


    my randam blood sugar levels is 250+ now increased from 120 few months ago. I am eating fruits like papaya, pomogrante orange etc., Food is Ragi and wheat chapathi. Still why the RBS is increasing ? should I stop eating fruits ? what shouls I eat . I am not taking any medicine.

    • ray

      Hi, some fruits have more sugar than others and if you check on the glycemic index of foods you can see the difference. I suggest you check the index to see what foods are low in carbs to maintain a low sugar level.

  53. Dianne Fraser

    What is the point of the chart above unless you specify if it applies to blood sugar levels after fasting?

  56. Teresa Nix

    I have had my Dr. tell me that he don’t know what my blood sugar count is supposed to be. I’m 6’1″ and my weight is 235. Sometimes when I get up, it’s already 180, without eating anything. Can you help me regulate my sugar? Or advice me on what I need to do.

    • ray

      Hi, the blood sugar levels chart is used for all body sizes. My suggestion is for you to keep track of what you eat by utilizing the glycemic index of foods. When I get up in the morning and my glucose level is high it means that I ate a lot of carbs the night before. My trick is to only drink water in the morning or some type of home made fruit smoothie with fruits that are low in sugar. Check the glycemic index for the right type of fruits.

  61. Tenisha

    Hello Dr., I have two children who I’m concern with there blood sugar level. My 3 year old Hga1c was 5.7 and my 6 year old was 6.2. Do have have to worry? Are kids blood sugar levels normally higher than adults?

    • Yves

      I guess that your 6 year old children have his weigh over a little bit. I suggest you either that your child must train physically in order to lose his weight, or consult your doctor. Good luck.

    • Jack

      Tenisha, an HbA1c of 5 -6% is great for a T1 diabetic child that age. 6% is the average for a non-diabetic and represents no increase in risk of complications vs a non-diabetic.

      The intent of the chart used in this article isn’t properly described.
