Yeah nothing automatic I just meant I can control my BS good in manual mode. I guess that’s not saying too much.

Basically the OP5 works well as a dumb pump. I don’t believe the 5 would work for me. For example I ate dinner and chased the lawn mower for an hour. BG per Dexcom dropped to 76. Without doing anything it began rising on itself. This is with C-IQ running, but I’ve had the same effect by suspending insulin delivery. BG will drop from activity and will rise up after stopping the exercise.
General rule, which you probably already know - after every exercise session:
- water
- carbs
- protein
- insulin
I know you have a lot of experience on the bike, so this is old news to you. But for so many people, and certainly for pump algorithms, they look at it like it’s crazy.
“Why would you take insulin after exercise?!?”
Because your muscles used glycogen, and the best way to get that glycogen replenished is with the help of insulin.

Just did all that after my strength workout. My personal trainer says that protein is needed in a window of a bit more than 20 minutes to effectively repair and build muscle after a workout. She doesn’t know about the need for glucose and insulin, but then she’s not a member of our tribe. Water goes without saying.

It’s interesting that some non-diabetic weight lifters take insulin to help them!
It’s like a black-market thing they buy.
Yeah insulin is very anabolic and shuttles carbs into the muscle. This is big with bodybuilders although very dangerous.
Carbs are needed first to replenish glycogen, protein later.
@John58, do you find that using Manual mode this way makes the algorithm underestimate your insulin sensitivity? So if you do use Auto for a bolus, you don’t get enough insulin?
This would seem to me the biggest issue if Imm using the Omni closed loop but also injecting, when there’s no way to tell the system I’ve injected. I’m beginning to think I’d be better off sticking with the “old” Omnipod, although I had looked forward to taking advantage of Auto mode overnight or when not eating.

I think the answer is yes…Actually when I bolus for a correction, correcting a high, I usually just plug in my own bolus amount when in Auto. I have noticed lots of times that if I let the Auto mode calculate a correction bolus it comes up with amounts that are usually lower than I desire. Sometimes, for example in the late night, I will go with the Auto bolus calculation for corrections and it does eventually bring the BG down but very slowly over several hours. So unless I am headed off to sleep I calc my own correction bolus while in Auto mode when knocking down a high.
As far as what all the manual fiddling is doing to the algorithm, I don’t think it is changing much because the TDD does not change much. My understanding is the only thing the algorithm “learns” from pod to pod is TDD. If a bolus is taken with a syringe instead of the pod the algorithm would be tricked into thinking your TDD is lower than actual and it might lead to more high BG? Not sure on that one.
Coincidentally your question caught me in an in-range (70-150) 24 hours, one of my best days for a while. The plot below shows a couple lows when I forgot to quit manual soon enough after eating. The second plot shows the red horizontal line signifying zero basal. That is what I look for when deciding how long to stay in manual before and after meals, which is unexplainable gut feel but seems to work.
