13 Warning Signs Of Low Blood Sugar & How To Fix It

Extreme changes in blood sugar levels are more common than you might think, and can lead on to serious problems if left unchecked. A 2015 review found that, among those with type 2 diabetes, mild episodes of low blood sugar occur an average of 19 times a year, with almost one severe episode on average annually. This was particularly common among those taking insulin. Thankfully, there are several warning signs that all is not well. Learn to identify when you hit a blood sugar dip and take action to stabilize glucose levels for the good of your health. Blood Sugar Highs & Lows Our blood sugar levels can affect so many aspects of our wellbeing – both mental and physical. But what exactly is blood sugar? Well, after eating, our food is broken down into various parts – one of which is glucose (sugar), which is either used right away for energy or stored for later use. For our bodily cells to be able to use glucose, we must be producing enough insulin, and our body must be able to use this insulin correctly. (Diabetics either cannot produce insulin or cannot use it properly.) If our bodies cannot do this, we experience fluctuations in blood sugar. We can also experience these fluctu Continue reading >>

    Hi all,
    I don't know if this is 'diabetic-related' but seeing as it's new to me and I'm only just coming up for my second year after type 1 diagnosis, I figured there may be a link and would appreciate any help/similar experience advice.
    For the past few weeks I can't sleep throughout the night and wake up with a very rapid heart beat at around 3am. It feels like a hypo yet 99% of the time, my levels are correct. I'm then wide awake and my heart feels like it's beating out of my chest! Eventually it calms down and sleep can be resumed but the constant interrupted nights are becoming a tad wearing.
    I don't want to take sleeping aids as I'm worried that I wont wake on a hypo. If anyone has experienced something like this - did you resolve it and if so how?
    HBA1C is 6.6. Currently taking Levemir and Novorapid. Generally speaking, quite good control. I've booked an appointment with the docs for this but not until next week.
    Many thanks in advance.
    Take care

    hi dave
    can't help exactly but sure can relate. i also get rapid beats, and that pounding feeling. i also get 'missed beats' when it feels like heart has missed a beat and makes up for it with a strong beat which makes me catch me breath. i have had the odd missed beat over the years but it increased dramatically during my last pregnancy (she's 2 now) - and although it calmed down after having baby, it has never gone away. the last few weeks it has bothered me more, especially as it happened whilst i was cycling at the gym, then 3/4's thru a spin class.
    the racing heart happens in bed also, just as i'm dropping off, and only once has woken me up. i know what you mean, because hypo's cause that adrenalin rush it feels very similar.
    don't know about you, but when it happens i'm sure i make it worse because i try to ignore it at first, then when it won't go away, i am convinced there is something wrong= more adrenalin added to the mix!
    i'm in my 12th yr of being t1, so i kinda thought it was related (altho my mum been t1 for 37 yrs and has never experienced this, altho she says her heart races every now & again). i first went to docs with it over a year ago, sent me for ecg which just said 'within normal range'. it calmed down a bit so i didn't pursue, but as it's been happening more i went back on monday - saw a great doc who has ordered another ecg so he can actually see it rather than just the comment that it was within 'normal range'. he said if it was a congenital prob it would've presented earlier, and i was too young (37) for it to be a wear & tear prob. (he also said he doubted it was related to diabetes but has told me to mention all this to clinic when i go in april)
    said if ecg rules out a couple of things he wants to check, then beta blockers may help (adrenaline causes your blood vessels to narrow and your heart to beat faster. by blocking it's action, beta-blockers cause your blood vessels to widen, slow down your heart and reduce the force at which blood is pumped around your body). i had been prescribed beta blockers previously for anxiety/panic attacks, but no one explained how they helped and i was too scared to use them! with explanation, i am far less worried about taking them and hope they will actually help me (if/when i get any prescribed!).
    do you get any missed beats? or is it just the racing? as doc was writing note on the system he described it as 'forceful' and that is spot on, exactly how it feels.
    know what you mean about sleeping tablets, i'd love to try but am too scared i'd miss a hypo.
    you are not alone! docs is best place for you...they can order tests and see what's what. i've done a lot of googling on this, i'm not sure that helps me though because i'm a worrier!!!! it does seem a very common problem that lots of people get, not related to being a t1. i was thinking it was menopausal...but maybe it's just a random thing :? !
    good luck at the docs

    I'd contact your DSN or doctor and ask them. It might well be nothing, but best to get it checked out. Sounds like your diabetes is under control so hopefully nothing to do with that. Sounds silly, but could just be a stressful dream that's making your heart rate increase?
    Let us know how you get on.
