Hi Guys

Hope your all well, I'm doing OK hut few problems last few weeks and wanted to ask about this correction on pump when BG is high then later on you Hypo??? Got up this morning BG 18.2 not sure if I hypo'd during night or just miss calculated carbs with Xmas cake 🙂 took Insulin to what pump told me at 6am had small walk with Dog 5/10 min 7am BG 12.6 Had Breakfast went back to be got up at 10.45 BG 4.6 by 11.15/20 BG 3.7. Had fresh fruit bowl and yoghurt so I know carbs were correct for Breakfast, have reduced my Basal rate but wondered if it was my correction for the high BG at 6am ?? I just dont know much about it can someone try explain a bit please , I had wondered if the correction would be out my system by 11.? so that would leave my Basal rate needing reduced
Sorry If im comfusing things

Hello there, we are advised that the long acting insulin (which is all that's used in pumps) stays in the system for up to 6 hours. For me I know it's less than this (max 4) but for others it may be there longer so it could still be the effects of the correction. It could also be your bolus/carb rate for breakfast - are you sure this is right? It could also be the basal rate mid morning. So a few things that it could be as ever(!!) but for tonight I would set my clock a couple of times to check that your overnight basal rate is ok to begin with. After this you can start looking at the other issues one by one. I find that if my day starts a bit wrong it tends to carry on being 'awkward' until supper. All the best.
 
The only way to be certain is by missing breakfast and doing some basal testing. But for most people the breakfast insulin should have finished acting by 4 hours later (btw Riri, it's only short-acting in the pump, def not long-acting!). You may need to check that your correction factor is correct (it's a good idea to review it from time to time). A good rule of thumb is to take an average of the last three days Total Daily Dose (TDD) and divide that into 100. For example if your total insulin (basal + bolus) is 25U per day, then your correction factor would by 100/25 = 4, ie 1 unit should reduce you be 4mmol. I find that my son needs a smaller correction at night than he would in the day.
 
Thanks Guys
Yes TTD was 33.608,= 2.97 day before 29.767, = 2.97 day before 27.442 = 3.6


Pump set at 3.4 so that would suggest ISF is to high ??? i am doing my best past few weeks to do Basal test but keep going low :( Iv reduced Basal Rate so see if this helps , Basal overnight is perfect only done it 1st Jan so I know there isn't a problem it has to be ISF or Basal. Yes Breakfast Bolus was 100 % had yoghurt and fresh fruit so again carbs deffo correct

Thanks Guys
 
I would suspect your correction was correct for normal usage ie snooze in bed, but as you went for a walk with dog that would lower it at a greater rate than normal. Personally if that was a one off result I wouldn't change anything until a definite pattern appears.
 
Yes Redkite - definitely meant short acting insulin in pump!! It was late and I was weary when I wrote it !😉
 
What PumperSue said - I suspect the exercise contributed to bringing down the BG. If I'm high but know im going to do some exercise I'll under-correct to avoid a post exercise low
 
Thanks all

AlisonF Your absolutely right in what your saying after talking to team this aft I'v to try 50% reduced Breakfast basal and go walk and see what happens as a starting point hopefully it wont resutl in a hypo/lowBG after walk. will let you all now how i get on
