    Hi

    I’m experiencing dips in BG below 4 during the day and night (I’m T2 and controlling through diet). I’m fairly newly diagnosed so I don’t know if I’m having a hypo or not. Reading about the symptoms of one, the only thing I feel is a little tired. I use a Libre 2 and at first I just thought that it was reading on the low side, but for the last few days I have been using a finger prick test to validate and while the Libre is always slightly lower, the finger prick also shows a low reading).

    I started proper keto (<20g of carbs per day) about 3 weeks ago (before that I was just in low carbs <50g per day). I eat two meals a day and have been feeling good on it.

    My gut feel is to eat some more carbs to try and get control of the levels, but I wondered if anyone has experienced anything similar. Clearly, I don’t want to come out of ketosis, but more stable BG levels are obviously more important.

    Thanks for any help.
    Nick

    If you’re not on medication and feeling OK then it’s highly unlikely you’re having a hypo. I quite regularly drop into the 3s without issue.

    Hi there, if it's any help my Diabetes Nurse said a non diabetic (or a well controlled type 2 not on meds I guess) can go down into the mid 3s and that for them that would be normal. What are your readings? x

    That’s interesting.

    My levels when I do go below 4 are normally 3.6/3.7 and I range between 4 and 5.4 for the main.

    That's exactly what you want to see when unmedicated.. you're very lucky to get such great numbers.
    May I ask which meter you have?

    I’m not on keto and today after work I had levels of 3.7, I’d eaten avacado and some Mexicana cheese for breakfast and soup and a creme egg (I know I shouldn’t but I’m weak for them) for lunch as well as having a large latte

    levels mid 3s now after work haven’t been unusual since I stopped meds, I actually asked about it on the forums and was reassured like you are being

    so yeah, possible for someone not on meds, I also feel absolutely fine. I actually when I was on drugs pre fitness got hypo symptoms when I was in the 5+ so not feeling strange is different.

    I lie, I got weird feeling once and I was 2.7, double tested. So I ate something. Not sure what my body is doing anymore

    it’s a bit weird though isn’t it, hypo is something we are warned of but diet controlled can get such low levels

    Thanks for that reply. What meds were you on? I was prescribed Metformin, which I didn’t want to take (determined to manage it through the thing that got me there in the first place) and have now stopped.

    I was on metformin 2000mg, weekly bydureon and daplaflaglozin before I got back into non diabetic levels. I lowered carbs and lost a lot of weight, for me I seem to be able to tolerate a lot more carbs than many though so I am very much now a fan of lowering carbs as a way to improve diabetes type 2. I also though do a fair amount of cardio which seems to help me keep the levels at bay and tolerate more carbs. I can see from testing what carbs can do though, some carbs like potatoes I can easily see into the next day

    I don’t know If longer term my body will lose the ability to cope though so keep an eye on things

    Inspirational stuff.

    I’m 4 stone down but have another 7 to go. Walking has helped me enormously and I’ll up the exercise as more weight comes off.

    Determined to get this thing understood and controlled.

    Libre 1 isn’t very accurate below 5ish. It told me I was dead a few times. I verified with a prick, and I was indeed alive. Verify with a prick when you get low,
