Im a T1, on dexcom G7 and Tandem pump, x2. The last several months have been particularly frustrating as my post meal BG always seems to rise about 2 hours after my meal. I’ve been careful to bolus accurately, wait for 15-20minutes before eating, and try to account for fat/protein. Lately, my BG spikes way after the actual meal. Would appreciate any help. Thanks.
Are you using ControlIQ? Any chance your basal is reduced/shut off for some time before the meal (like the pump sees you are low so adjusts your rate)?
Thanks for replying, I am on Control IQ but basal has remained the same. Kind of wondering if that’s the problem and it needs adjusting.
Maybe your food is fat/protein heavy, so causes delayed digestion and late highs?
I wondered that too, thanks for the reminder, I’ll do a better job of watching that.
It’s unlikely the pump settings or control iq because that handles long term sugars. This issue is likely that you didn’t bolus enough.
Of more likely , your infusion set has stopped absorbing correctly.
When I was on Tandem I had a slight allergy to my sets and likely the adhesive. If I pumped more than. 50 units a day, it would just not absorb.
The sites were often red inflamed and sometimes hard to the touch. That’s a sure sign that you aren’t absorbing insulin.
I lost my pump on an airplane and I had to switch to omnipod until I could figure out a new pump.
I found that I wasn’t allergic to omnipod and I had no issues with absorption. 7 months later I’m still on pods.
The AID algorithm is better on tandem, but the absorbtion issue is gone so my control is much better. From 85% in range to 95% in range in average.
I still think Tandem is a great pump, but for me, pods are better.
A couple of things can help, use Flonase on your skin before putting in your set, and use some oil based ointment right at the spot of insertion, I used to use neosporin, but it’s the oil that blocks the adhesive from getting into your skin, not the antiobiotic.
You can even use Vaseline, but a tiny bit so it won’t spoil the stickiness of the tape.
I was using varisoft and just put a tiny drop on the needle before inserting and it helped a lot. .

I often add a temp rate when I eat to prevent my glucose levels from surging. I also have several personal profiles with different basal rates which I can utilize depending on what I’m eating.
