Why does ny blood sugar go up overnight ?

[goodybags]

Hi Goodybags, tbh I haven't felt great on MJ, feel quite dizzy and just 'not right'.
My HBA1C was 68 before MJ, got a blood test in a few weeks so will be interesting to see if it's come down.
My diabetic nurse told me to reduce my insulin from 30 to 26 but my levels really spiked so after christmas I put it back up and have managed to reduce it to 28.
I think they will put the MJ up to 7.5 though.
No other side effects apart from a little nausea.
How about you ?

I’ve actually got on very well on Mounjaro since last summer, previously I had been taking a oral SGL-2 that for me, had side effects, and previously to that was taking a different weekly injection, although that one didn’t have any side effects TBH never really helped
either in weight loss nor bringing down my HbA1c

I definitely get FOTF rather than DP. I have had 2 sessions of it today. The first when I got up this morning. Then I had to go back to bed with a migraine which wiped me out for most of the day and I got a second wave when I got up this afternoon. What I find interesting about it is that with eating carbs, say after a hypo, Libre takes ages to catch on that levels are rising, but FOTF is picked up almost immediately with Libre when I swing my legs out of bed and stand up. It is almost like there is a tilt mechanism on it. My levels also tend to go down when I lie down too but it isn't quite so obvious.

Sorry, i don't understand some of the words you use. It has always been explained to me in much simpler terms.
I know it is recommended that people who treat their diabetes with basal - bolus regime reduce their basal insulin for up to 48 hours after intensive exercise. I have found this is cumulative - on a 10 day walking holiday, I needed to reduce my basal each day to avoid hypos because my liver dripped/dumped less glucose.

Well naturally you have to lower your insulin needs when exercising, as muscles will use glucose via a non-insulin pathway when exercising (GLUT-4 translocation). Effectively, they suck it up to use it for energy and having too much insulin in your system will cause hypos. (Even as a type 2 on no medication, mine can get very low when I exercise, especially in combination with carbs, but it recovers quite quickly as my insulin is naturally cut off.)

Your liver will have to release more from its glycogen stores to top the blood stream up. If the stores are depleted, it will make it from fats and amino acids. If anything, if you are doing a lot of walking, your liver might actually be releasing more glucose to keep the system topped up.

In principle, regardless of sex or age, sleep deprivation is not a good thing. In recent years there have been various studies across the western world about the physical and psychological effects, some not as conclusive as others. The NHS offers some pointers:

Sleep problems - Every Mind Matters

Learn about sleep problems, including what it means to be sleep deprived or have insomnia. Plus find out how sleep hygiene can help if you are struggling to sleep.

www.nhs.uk

However, I'm not convinced that getting "sleep tips" sent to one's inbox is such a great idea. It takes a lot of self control to not turn to a sleep interfering screen, when already awake in the small hours.

Needing a wee several times a night is clearly unhelpful as well, or are the restless legs the main cause of your interrupted sleep?

What insulin(s), including any letters or numbers on the packaging and with what typical dose size? Is this a background basal, once or twice a day? Or a combined basal/bolus insulin, usually twice daily? Or possibly even 2 different insulins: basal (once or twice daily) and a bolus insulin with each meal - ie Multiple Daily Injections (MDI).

Delighted that someone has had the vision to recognise that a CGM can be appropriate for you. Not all T2s are so fortunate.

Hi I'm on Humalog mix 25, twice a day.
Usually each dose is 28.
I've struggled with sleep for a few years, having to get up for a wee every few hours doesn't help.

I found HRT stopped that completely and I now sleep right through without any need for pit stops at all. It was one of the most surprising and immediate effects of using the HRT patches. Literally the second night of having a patch on and I slept right through and have done ever since (several years now) and it is bliss getting good undisturbed sleep and obviously good quality sleep is also important to diabetes management.

I did not refer to lowering insulin WHEN exercising, especially as it depends upon the type of exercise - resistance exercise (e.g. climbing) requires me to INCREASE insulin when exercising.
I was referring to reducing insulin AFTER exercise which is necessary for all types of INTENSIVE exercise.

You said this.
That you had to reduce background insulin when walking.

This discussion is over for me.

Yes, walking fast, uphill or for long periods. The walking I referred to was hiking in the Himalayas for 8 hours per day.
But that is me. I walk every day so a walk to the shops is not intensive. But, it is relative, others can find a shorter walk to be intensive for them.

I'm a bit confused, I always thought your blood sugar goes down overnight, but mine seems to be fairly stable and dips slightly around 3am and then goes up ?

Hello, your BGs are fine till 3am then a drop following a rise? What time do you inject your Humalog mix 25? Is it prior to your evening meal? What in general are you eating for evening meal, when this happens?

I find exercise mates zero difference to the vertical upward line which is my DP.

This is a pretty standard representation even with 8.5U of NR 45mins before I have a low carb breakfast even with a good run the night before...

Even after running a marathon?

I don't get any difference with exercise if I'm used to doing it (e.g. a 40km round trip commute on the bike), but if I've either not done much for a few weeks or do something significantly longer then I will get a drop/elimination of FotF. I only tend to start getting DP when I've not done any exercise at all for a while (e.g. due to illness)
