    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).

    • Michael McKinley November 16, 2016 at 2:30 am - Reply

      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.

    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 November 16, 2016 at 2:47 am - Reply

      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.

      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.

      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 !

      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 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?

      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.

      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.

    • ray August 2, 2015 at 10:58 am - Reply

      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.

      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 August 19, 2015 at 11:28 am - Reply

      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.
