and then again, gentler drops can sneak up on you and you don't notice them until you're well down in the 3s or lower!
Quicker drops can and you may not feel them until under 3.0. If the drops are gentler you may well feel them above 3.0 and nearer to 4.0.
You are quite right. We do measure blood sugar which will not give the same reading as other body fluids. My lowest BS, while still standing and talking was 0.9. Usually my legs go at 1.4 and I am unconscious below 0.8. However I usually have lower BS, probably because there are so few carbs that I like. I wonder if there is any research on brain damage/dementia and type 1. I assume the incidence will be greater for both conditions with diabetics?Precisely. And what most people consider to be the hallmark sign of hypoglycemia, confusion and inability to function mentally (as well as physically) depends on how your brain functions with lower glucose concentrations. But we measure glucose in the bloodstream not the brain tissue. And we can adapt to lower levels of glucose than the average person. But sooner or later if the sugar keeps dropping it will win. Every time.
Actually I remember reading some article awhile back that said hypoglycemia episodes don't lead to brain damage long term.You are quite right.

Have been using Libre for 2 yrs and have found my awareness to be improving.
I am lucky in that Libre gives me very similar readings to blood so can use it to learn. Now I recognise small symptoms even subconsciously.
I awake at night in the 4 s,. If dropping quickly at around 5.0, if slowly nearer 4.0. This is similar to daytime awareness but actually quicker/earlier. Daytime is more like 4.5 (fast) and 3.5 (slow) when I can be certain without checking with Libre - but I find I have actually checked(scanned) without realising that I have felt the symptoms, if that makes sense.
I have found the lag time (time difference between ISF readings and blood) is shorter when going down than when rising; which I believe is the algorithms they have developed to reduce lag and is confirmed by trials. About 5 minutes lag on avaerage but 0 lag when falling and almost 15 minutes when rising. Quite important when working out how much glucose is needed to raise levels without massive rebound.
If falling slowly I will start at around 4.0 with only a 1/4 glucotab, around 1gm of fast acting carb. If falling fast then up to 1 tab (4 gm ) . Then check in 15 minutes and redose if/as needed.
Can now level it out at around 6 without shooting up to the teens
So much information from Libre opening up a new world. I would never have dared run so low before without much greater glucose dose and certain hyper following. The old days of 2-4 glucotabs for a hypo have gone thankfully!
On top of the blood/ISF lag, I believe there is a brain/blood lag. It takes about 5-10 minutes for brain symptoms to follow other physical symptoms. An interesting topic.
Hi guys, quick question for you on a Saturday arvo!
Just wondering when you should start to feel hypo symptoms? It's quite rare I feel anything above 3.5 (sometimes false hypos at around 4.5 if I've been quite high that day). Today was 2.9 which is closer to when I usually realise and I've been as low as 2.2 before without twigging something was going on.
Just curious as to what the 'Norm' (if there is such a thing in this T1 word!) is?
Many thanks in advance for your help!! xx
