Before the Omnipod 5, I was on multiple daily injections (MDI) — four to six shots a day, plus a CGM, plus a whole lot of mental math. I managed well enough. My A1C was in range. But I was exhausted by the constant decisions.
Going to a closed-loop system felt like handing off some of that cognitive load to an algorithm. Six months later, here’s my honest assessment.
What “Closed Loop” Actually Means
The Omnipod 5 communicates directly with the Dexcom G6 (or G7) CGM and adjusts basal insulin delivery automatically, every five minutes, based on current glucose trends. It’s not fully automated — you still bolus for meals — but it handles the overnight basal adjustments and the micro-corrections throughout the day.
The goal is reducing the manual labor of T1D management while improving time-in-range.
Month by Month: What Changed
Month 1: Chaos. I spent a lot of time watching the algorithm make decisions I disagreed with. The system was learning my patterns, but I wasn’t trusting it yet. I overrode it constantly and essentially undermined the whole point.
Month 2-3: I stopped fighting it. My time-in-range went from 68% to 81% almost immediately after I stopped overriding. The overnight numbers improved dramatically — I woke up in range almost every morning for the first time since diagnosis.
Month 4-6: New normal. The algorithm knows my body reasonably well now. I bolus for meals, the Omnipod handles the rest. My A1C at my last appointment was the lowest it’s ever been.
The Stuff They Don’t Put in the Brochure
Pod failures happen. They’re not common — maybe one per box of ten — but when a pod fails mid-wear, you lose insulin delivery without always realizing it immediately. The alarms help, but it can take 30-60 minutes to notice and correct.
The algorithm is conservative. It errs on the side of not delivering insulin, which means it’s better at preventing lows than preventing highs. If you’re someone who runs high after meals, you may need aggressive meal boluses.
It’s bulkier than MDI. The pod is small, but it’s not invisible. For certain outfits or activities, you’ll notice it’s there.
Would I Go Back to MDI?
No. Not even close. The mental load reduction alone — especially overnight — has changed my quality of life in ways I didn’t expect. I sleep better. I worry less. My numbers are better.
Closed-loop isn’t magic, but it’s genuinely the future of T1D management. If you’re eligible and your insurance covers it, the conversation is worth having with your endo.
