    Hi there

    I don’t think there’s a definitive answer. Looks from other posts that you’re type 2. Are you taking any medication for it or using insulin? Do you have a way to test your ketone levels? It’s the combination of high blood glucose and ketones that is of most concern.

    If you’re seeing very high numbers I’d give your GP a call or if 20 mmol or above, call 111.

    Then it’s very unlikely you’d get DKA, which is what happens when very high blood glucose and elevated ketones coincide. However, if you’re worried, give the doc a call.

    There's two kinds of dangerous here - short term keel over dead if not treated dangerous and long term give you diabetic complications if you run those levels for too long dangerous.

    1) Short term dangerous are hypos - your bg goes down below 4 (at which point you can start to get confused and eventually keel over if it's down to the 2s). Not an issue for you on your current medication. The other is DKA - high blood sugars (usually over 15) over many hours together with high levels of ketones (note you get some ketones with dietary ketosis and that is normal and safe). It's caused by lack of insulin so is not usually an issue for T2s who typically over produce (though very long term T2s can eventually burn out their insulin producing cells). Having said that, many many T1s/LADAs (LADA is slow onset T1) get initially misdiagnosed as T2 and only get the T1 diagnosis when they present to A&E with a blood sugar of 30 and high levels of ketones. Whatever your type, contact a medical professional if you're running that high, because it really isn't good.

    2) Long term damage leading to all those potential diabetic complications. Ideally, you want to keep your bg below 8 most of the time (non diabetics do exceed that occasionally). As a T1 for 50 years I aim for under 10 for as long as I can manage but know that my life span will be impacted slightly by my non normal levels. But I've kept the complications at bay so far so that's good enough for me. Your hba1c is a good measure of average blood sugar (though it doesn't detect lows and highs) so it's one easy measure that doctors use to see how your levels are going.

    Good luck.

    There are meters that do both blood sugars and ketones with the proper strips.

    For instance the Caresens Dual and also the Libre reader can use ketone strips as well as glucose strips

    But be aware that ketone blood testing strips tend to be very expensive compared to glucose testing strips so you don't want to be using too many of them....(Unless your doctor is giving them to you on prescription).

    Hi @Stephanie 1233

    what kind of readings are you seeing?
    And are they consistently high? Or do you start with lower readings which escalate during the day?
    Are you finding you are thirsty and drinking a lot?
    Losing weight?
    Feeling very sleepy?

    focussing on DKA (diabetic ketoacidosis) and ketones are not always helpful in T2s
    it is very important that you do not take make the assumption that your symptoms and T2 issues will be the same as those of T1, and please verify whether the person giving you advice is doing so from the perspective of T1, in which case their advice may be misleading.

    Some T2s can have low (or zero) ketones, at the same time they experience the symptoms I just described above, whereas ketones are a much better gauge for T1s.

    The reason for this is because T2s may have sufficient insulin circulating to prevent ketones, but insufficient insulin to keep blood glucose down to safe levels. Sometimes this develops into something called HONK https://www.diabetes.co.uk/diabetes-complications/hyperglycaemic-hyperosmolar-nonketotic-coma.html
    Which does not present with high ketones, and may develop into a coma.

    i strongly suggest that if your blood glucose numbers rise beyond the guide range that your medical team has given you, that you get in touch with them for advice, and please do not interpret ‘the absence of ketones’ as making ‘it all OK’. If you have not been given a guide range for your blood glucose, then ask your team for one.

    Sounds like a good plan to call the doctor. Hope you get some answers and let us know how you get on.

    Hi,

    Keep an eye on those BG levels. Appreciated you don't have a ketone meter.
    Here is some NHS advice, don't hesitate to call 111. https://www.nhs.uk/conditions/diabetic-ketoacidosis/

    Best wishes.

    Getting the lab work done is an excellent idea ........
