Weird reaction to insulin tonight!

I wasn’t sure at first, but, suspected for a while, that injecting insulin at night seems to have an opposite effect, on me, & actually raises my blood sugars. There is maybe an issue with me being menopausal now: hormones?

I slept this afternoon, just after having my dinner early at 15:00, & woke around 19:00. I got up & tested at 19:30 BS 8.2. I thought I might get hungry later but, no was quite happy. 21:30 rolled around & still not hungry! So, decided to test to see if my basal dose was right for me, as I remember from a link from Trophey wench. BS 8.3, reassuring that it’s holding steady!

Now, this next bit may not have been completely sensible but, I wanted to test how much 1 unit of Novorapid would bring my BS down by in 1 hour.

After seeing my hospital team on 22/03/18, my dietian, despite officially not advocating carb counting in T2’s, agreed to teach me. I got my appointment to see her on 24/04/18.

I’m getting 2 free new meters from Freestyle Abbott, from their Progress programme, an upgrade of my very old Freestyle mini to a Freedon lite & an Insulinx. I told them I had been testing 8-12 times a day since being ill in hospital last May 2017, due to the high doses of steroids I was on for weeks & the ongoing effects on my BS. My hospital team need the readings to adjust my insulin doses. There’s a insulin calculator on the insulinx.

After searching for threads about the insulinx, I found one very helpful post, about 5/6 years ago, where there were 2 links, 1; her review of the meter & 2; the training course that was run by the Abbott company to train people about carb counting & how to use it in conjunction with the meter.

That 2nd. was very useful in that I learnt how to work out my insulin to carbs ratio & how to use how much 1 unit of bolus brings down my BS by in 1 hour with the calculator.

So, I thought I would try & find that out. I injected 1 unit Novorapid just after testing at 21:30 & tested it exactly 1 hour later, timer on Timesulin cap, & was mildly surprised to find it had risen to 9.2.

I had noticed that if I bolused for a late night night snack; sugars are higher on waking in the morning. But, if I didn’t bolus for it, my sugars were lower in the morning. I wasn’t sure as I’m not snacking as much as I did since my reduction in cals from around 4000/day to around 1200-1500/day.

Not only that, I wasn’t hungry at all before injecting & now started to get very hungry. I gave in & had sandwiches & tea around 23:00 & bolused for it. I wouldn’t be surprised if my BS is higher in morning.

Is this normal? My BS always dropped as the day went on & overnight before I was menopausal: less than a year now!
 
As suspected my BS is now 11.7 at 02:21. Don’t know what’ll be in the morning. I wish I had a libre, I see people on these forums have, so, I could tell if my BS is increasing, lowereing or staying level.
 
Can’t sleep anyway so I monitored. 04:00 BS 12.1. 05:35 BS 7.9. What is going on?
 
06:34 BS 7,5.
Morning Lanny. Diabetes is a complicated condition made no easier to understand by all the other influencing factors that affect our personal blood glucose levels. I noticed you are T2 on insulin therapy like myself. I am on a basic Humilin 1 injection twice daily, not MDI. It works for me at the moment. My levels are usually between 5 to 8.5 my morning reading (after I've carried out a few chores) is consistently between 5 and 6.
I do occasionally have way out readings, sometimes I conclude what may have caused them, sometimes I just don't know.
My theory is that as T2s our pancreases are still producing insulin whereas a T1 does not. I have therefore concluded that as T2s we have less control over our bg levels than a T1 since they can control the amount of insulin their bodies have, whereas we as T2s have an unknown quantity of pancreas produced insulin as well as that which we inject. I have no idea what amount my pancreas produces on a daily basis so I have to make a rough judgement of what I can reasonable eat. Being diagnosed with autoimmune pancreatitis doesn't help with the balancing act we diabetics have to endure on a daily basis. I have no doubt you have other conditions that affect your bg levels. Stressing about what is happening doesn't help the situation either, so I learnt not to worry about level variation too much. We are lumbered with this condition 24/7 and we cannot obsess about it too much otherwise it controls our whole lives. Of course this is just my opinion and you may know better than me and I would love it if you could trash my theory. Take care, Dave
 
Hi @Lanny . As Davein has said many things can affect our levels, just getting up to go to the loo can affect mine either way.

When you say
So, I thought I would try & find that out. I injected 1 unit Novorapid just after testing at 21:30 & tested it exactly 1 hour later, timer on Timesulin cap, & was mildly surprised to find it had risen to 9.2.
I had noticed that if I bolused for a late night night snack; sugars are higher on waking in the morning. But, if I didn’t bolus for it, my sugars were lower in the morning. I wasn’t sure as I’m not snacking as much as I did since my reduction in cals from around 4000/day to around 1200-1500/day.
What were your starting levels, as, sometime what seems to be a big difference is not actually so.
Also what Rapid insulin are you on as their has been reports of an iffy batch of Novo Rapid. I’ll put a link to @Kaylz post regarding it, so you can check cartridge/pens

Just re read this,
The difference is most likely due to contamination on your finger or a dodgy strip as the figures in the 2 later posts were fine.
I’m wondering if it was the same problem for the other tests your concerned about.

I don’t think it’s contamination as I wash my hands before every test or, if I don’t want to get up, use a Dia wipe. Also, this sudden drop in BS has happened before, why I’d already suspected, last time 02/04/18. Excerpt from diary:-

17:00 Dinner 471.8cals 59.96g carbs (BS 8.4) 4 units Novorapid. Leftover Easter Sunday Lunch.
1/3 chicken joint & stuffing asda 257cals 5.8g carbs
95g potato baked 87cals 20g carbs
135g steam veg birds eye sun. mix 73cals 11g carbs
140ml chicken gravy bristo 39.2cals 7.56g carbs
150ml shloer rose 66cals 15.6g carbs (BS 12.2)

21:00 Snack 164cals 10.65g carbs (BS 6.5) Wow! That was a big drop in 2 hours! Try not adding insulin & see what happens to BS in the morning?
2 oatcakes nairns 72cals 8.7g carbs
15g no sugar peanut butter sun pat 92cals 1.95 g carbs

23:00 (BS 6.4) Ah! I’m dropping despite the snack! Was it a mistake to add insulin for snacks before bed? And my body compensated overnight with higher BS in the morning? Does it have anything to do with hormones? I’m menopausal now.

03/04/18 (1264.995cals) woke at 06:00.
06:15 (BS 6.9)

BS in brackets are before the meal & 2 hours after the meal.

I have seen the posts by Kaylz about faulty Novorapid & checked my batch nos. They are not the cartridges & are 300 unit flexpens with different batch nos.

My new meters arrived in this morning’s post & I tested the meters from the same drop of blood, huge one for the 3 meters, from the same cap of strips & they all read the same. At 11:40 BS 11.6 after finally testing at 07:30 BS 6.9 & sleeping straight after.
