    I am a 30 year old, 78 kgs, slightly over weight with belly.

    I used to do regular checkups, as my job requires regular medical tests.

    I did one of my test in June 2018, random blood sugar was 4.88 (I remember taking the test 3 hours after eating). Then I did a test a month later in July 2018 as my company requested for VISA application and the result was normal. I don't remember the number.

    I changed to another company and as part of that I did a medical check-up in Jan 2019. My fasting blood sugar was 5.88 and blood sugar level after 2 hours eating taken on the same day was 8.66.
    The results were in prediabetes range.

    I am worried about the results. Do the sugar levels very day to day or based on what we are the night before the test. How can the result vary drastically in 6 months period?

    Hi @Martial, Welcome.
    If you look at the Home page and Pre-diabetes on the far left of the horizontal menu bar it quotes the fasting range for pre-diabetes is greater than 5.5 mmol/l. Please read up on Pre-diabetes so that you are appraised of all the facts.
    Before you wonder why you results are so much higher I think the figures you are quoting are in units called mg/dL.
    So to convert you multiply 5.5 by 18 = 99 mg/dL. That would suggest your result of 106 mg/dL fits into the pre-diabetic range, as you were informed (but please check these figures and units with a nurse or doctor to be certain).
    If you also look at Living with Diabetes on that same menu bar, about middle of the bar, the far left column and top heading:
    blood sugar levels - you will see that for non-diabetics a normal reading for more than 90 minutes after a meal is
    up to 7.8 mmol/l = 140 mg/l.
    You will need to see your doctor to work out what to do about your pre-diabetes fasting blood sugar level.
    But whilst you have the Home page up, do visit Type 2 Diabetes to see what happens if pre-diabetes progresses and what is done to treat it and even sometimes reverse it. Best Wishes:):):)

    Hi welcome to the forum

    I'm tagging @daisy1 for a new member post for you.

    Please don't worry as 5.8/106 fasting level is just a bit outside normal in the US, I'm sure you can turn this around with small lifestyle changes.

    I'm based in the UK and we no longer use fasting levels for diagnosis but I was diagnosed with impaired fasting glucose based on a reading above 6.1.

    I highly recommend you read this article about how levels deteriorate in pred/type 2


    Sugar levels vary day to day based on food, sleep, exercise, stress or ill health and weather etc etc. Saying that my fasting levels do not vary that much day to day unless something extreme happens. It's mostly a very slow drift up or down.

    They vary hour to hour. If you're worried, ask for a hba1c test. That shows what your average blood sugar has been in the past 2 months.

    Hello Martial and welcome to the Forum :) Here is the Basic Information we give to new members and I hope you will find it interesting and helpful.


    Diabetes is the general term to describe people who have blood that is sweeter than normal. A number of different types of diabetes exist.

    A diagnosis of diabetes tends to be a big shock for most of us. It’s far from the end of the world though and on this forum you'll find well over 235,000 people who are demonstrating this.

    On the forum we have found that with the number of new people being diagnosed with diabetes each day, sometimes the NHS is not being able to give all the advice it would perhaps like to deliver - particularly with regards to people with type 2 diabetes.

    The role of carbohydrate

    Carbohydrates are a factor in diabetes because they ultimately break down into sugar (glucose) within our blood. We then need enough insulin to either convert the blood sugar into energy for our body, or to store the blood sugar as body fat.

    If the amount of carbohydrate we take in is more than our body’s own (or injected) insulin can cope with, then our blood sugar will rise.

    The bad news

    Research indicates that raised blood sugar levels over a period of years can lead to organ damage, commonly referred to as diabetic complications.

    The good news

    People on the forum here have shown that there is plenty of opportunity to keep blood sugar levels from going too high. It’s a daily task but it’s within our reach and it’s well worth the effort.

    Controlling your carbs

    The info below is primarily aimed at people with type 2 diabetes, however, it may also be of benefit for other types of diabetes as well.

    There are two approaches to controlling your carbs:
    • Reduce your carbohydrate intake
    • Choose ‘better’ carbohydrates
    Reduce your carbohydrates

    A large number of people on this forum have chosen to reduce the amount of carbohydrates they eat as they have found this to be an effective way of improving (lowering) their blood sugar levels.

    The carbohydrates which tend to have the most pronounced effect on blood sugar levels tend to be starchy carbohydrates such as rice, pasta, bread, potatoes and similar root vegetables, flour based products (pastry, cakes, biscuits, battered food etc) and certain fruits.

    Choosing better carbohydrates

    The low glycaemic index diet is often favoured by healthcare professionals but some people with diabetes find that low GI does not help their blood sugar enough and may wish to cut out these foods altogether.

    Read more on carbohydrates and diabetes.

    Over 145,000 people have taken part in the Low Carb Program - a 10 week structured education course that is helping people lose weight and reduce medication dependency by explaining the science behind carbs, insulin and GI.

    Eating what works for you

    Different people respond differently to different types of food. What works for one person may not work so well for another. The best way to see which foods are working for you is to test your blood sugar with a glucose meter.

    To be able to see what effect a particular type of food or meal has on your blood sugar is to do a test before the meal and then test after the meal. A test 2 hours after the meal gives a good idea of how your body has reacted to the meal.

    The blood sugar ranges recommended by NICE are as follows:

    Blood glucose ranges for type 2 diabetes
    • Before meals: 4 to 7 mmol/l
    • 2 hours after meals: under 8.5 mmol/l
    Blood glucose ranges for type 1 diabetes (adults)
    • Before meals: 4 to 7 mmol/l
    • 2 hours after meals: under 9 mmol/l
    Blood glucose ranges for type 1 diabetes (children)
    • Before meals: 4 to 8 mmol/l
    • 2 hours after meals: under 10 mmol/l
    However, those that are able to, may wish to keep blood sugar levels below the NICE after meal targets.

    Access to blood glucose test strips

    The NICE guidelines suggest that people newly diagnosed with type 2 diabetes should be offered:
    • structured education to every person and/or their carer at and around the time of diagnosis, with annual reinforcement and review
    • self-monitoring of plasma glucose to a person newly diagnosed with type 2 diabetes only as an integral part of his or her self-management education

    Therefore both structured education and self-monitoring of blood glucose should be offered to people with type 2 diabetes. Read more on getting access to blood glucose testing supplies.

    How can the value increase from post meal reading of 4.88 to fasting reading of 5.88 in six months?

    I have never been diagnosed with diabetes before.

    Morning fasting readings are notoriously unpredictable. Have you searched the forum for threads on Dawn Phenomenon or liver dump?
