My teen son has been running high for 2 days 160-260. We got him down before dinner last night at 99, but that was with no carb/bolus for about 6 hours, only corrections. And he just went back up again after dinner. Had the Omnipod for almost a year and any failures usually came with alarms. His CGM confirms his rises. There may be a host of other reasons; stress (state testing), says he feels a cold coming on, not so ideal food choices (but only a few of the meals), corrections taking long to work, not enough time to pre-bolus high numbers down (ie breakfast before school, lunch at school we don’t pre-bolus to avoid potential problems). I have even given correction boluses by shot. I wish I could have kept him home to bring it down, any suggestions, we have never had so much trouble bringing numbers down. thanks. 
I have experienced this on rare occasion. It may be any number of things (like you mention). You might also check the insulin efficacy (is it older or have you had it out of the frig for a long time and/or exposed it to significant heat changes, such as carrying it in you or your son’s pocket, etc). It may also be a factor of pod placement. On occasion I’ve inserted into an area that has probably built up some scar tissue, so the insulin abosorption is marginal at best. It could also be a lack of subcutaneous fatty layers where you’re injecting (although if you corrected w/ a shot and nothing really happened, I’d probably lean back towards the insulin as the culprit). For example, I have worn the pod on my calf before, but I have really muscular calves w/ almost no fat on them…I never received a delivery error, but nearly all of my boluses while in that location failed to correctly cover or catch my BG from skyrocketing.
If you consistently see highs (and he thinks he might have a cold coming on) it might be useful to increase your basals (to +25% or +50% for starters) as your son’s body may be fighting an infection. Again also check the insulin and/or try a new bottle to see if that helps.
Hope you find some better numbers and some relief soon!
Thanks for the response, we will do a pod change when he gets home. I would like to think it was bad insulin but it has not been exposed to those issues. Last pod session he has great numbers (same insulin vial), even a 6-hour flatline during the early morning hours. Thanks for your help. Got to get to work. Check back later. 
Honestly, that doesn’t sound like a pod that isn’t delivering insulin. We’ve had one that wasn’t delivering and the numbers were way higher than that (high 300’s with ketones) - unless your son is still honeymooning
Kids will have random numbers like this. It’s frustrating, isn’t it? Hormones, growth, bad insulin, illness and stress (as you mentioned) are probably more likely. Their insulin needs just change sometimes, might be temporary or permanent.
We’ve had a rough few days since Easter, and I think all the chocolate she ate (high fat%) contributed to some insulin resistance, plus hormones - so fun
Since you did corrections by shot too and still couldn’t get things moving, my best guess is that it isn’t a pod issue.
A couple times I’ve had similar issues & changed to a new bottle of insulin which resolved the issue. It’s also possible the pod could be in a spot where the insulin delivery just isn’t doing the trick.
Thanks for all your suggestions, he was still high at school today. I was planning to do a pod change when he got home but about 4 hours after lunch with 1 correction, he started to lower. We pre-bolused for snack with a BG of 108 minus some insulin because we would be exercising an hour later, climbed to 158(on cgm) @ start workout, slowly decended during and wound up 59 BG after. Dinner is looking normal. I would say we were probably thrown a curveball. Stress (state testing), not accounting well for protein/fat, not pre-bolusing or fighting a cold, most likely a combo of most of them. Changing pod on schedule tonight. Thanks for all your help.
You bring up a good point I forgot to mention too. I am a pretty active person (cycling/running/swimming) so sometimes if I’m high and my numbers don’t seem to be coming down w/ insulin, I will go for a run or a short trainer ride to see if that will help. Usually that, in combo w/ the IOB, will help bring me down. Obviously this doesn’t answer the question of why the numbers were high, but it does help to rectify the situation in some cases (just one more thing to add to your arsenal for combating high BGs, which is always a good thing
Glad to hear your son’s number came back down. Hopefully the pod changed helped as well and you saw better numbers this AM. Good luck w/ any remaining state testing stuff at school as well as that cold that might be coming on!
Thanks for your added support. Its too bad he cant bring highs down with more activity whenever he wants because its a great way to see high numbers drop, like you said. Sitting all day in class. In fact in middle school, last year during which he was diagnosed, his PE was right before lunch. Recipe for disaster. On MDI then, he would be high after breakfast (so no snack) and then low before lunch. High after lunch because he had to correct a low. We didn’t know about pre-bolusing and extending boluses that help us out now. And now that we have been on the cgm a week and a 1/2, we are going to start looking for some patterns and tweaking the insulin dosing, systematically testing all our settings-thanks to “Pumping Insulin” by John Walsh, gosh thats a great book! Thanks loads for your concern!
I was just about to post the same question, last week I’ve had exactly the same problem, being really high after meals having eaten the same food (250) then delivering correction boluses that didn’t bring it down, then I injected from the same vial and they did come back down (so it wasn’t the insulin) definitively the pod wasn’t delivering.
Also, yesterday I injected insulin with a syringe at lunch (5 units for a chicken combo in a restaurant) and it worked perfectly (125 postprandial) then today I had the exact same meal and bolused the same units … 2 hours later 229 !!
I think there’s a problem with this lot of pods.
I’ve been on the pod for 2 months now and always wear it in the same spot (lower back)
I should also say that a couple of times I let the pod on even as it said that it should be changed … until the pod started screeching and it said that no insulin was being delivered. Then I changed it, I don’t know if this has anything to do with it.
You might want to try some new pod locations. Some people develop absorption issues from using the same spots over and over. That’s true of any pump you use, not just the pod.
Thanks, I wear it in the lower back, always trading sides, but it’s only been 2 months with the pod, I wouldn’t think that’s enough to develop absorption issues. I always injected in the same place for 2 years and never had problems (upper buttocks). I’ll try a different location anyway and see what happens.
I’ll talk to the distributor to see if they can change the box for another one with a different lot number.
