An update on the 670G pump

It’s been 3 weeks since I started on my new Medtronic 670G insulin pump, 21 days since that life changing day I wrote about. So you’re probably wondering if it’s as great as it seemed to be after those first 2 hours. Honestly, no, it hasn’t been as smooth and hassle free as I had hoped. But after 3 weeks, I can definitely say it’s made an improvement to my life and my blood sugars and I’m so glad I made the switch.

Let’s start at the beginning. About 3 hours after posting how great the pump is, it kicked me out of the auto mode and I got stuck in an endless loop of it asking me for a blood sugar to calibrate, calibrating, asking for another blood sugar, processing, and then saying to wait. This went on for hours. Finally I called the medtronic helpline and spent an hour on the phone with a support person. After the hour, he still couldn’t fix it and I ended up having to take out the sensor which was working fine. It was a frustrating start.

After putting in a new sensor, things seemed to be going better for awhile. I was able to get back in the auto mode feature. My blood sugars have had way less drastic highs and lows, although I still find myself in the 200/250 range and the auto basal doesn’t seem to do much to bring it down. I’ve also had fewer lows especially those that are a result of correcting for the high spikes.

The alarms are a bit annoying, I find that even if I calibrate before bed, it still might need a calibration in the middle of the night, and I get awoken by the buzzing. I find that most often when I do get kicked out of auto mode, it happens during the night. I’ve also gotten stuck in that same loop of repeatedly asking for a blood sugar and not getting back into auto mode for a few hours a few more times. But luckily I haven’t had to take out any other sensors.

I had my 3 month endo appointment yesterday, and even after only having the new pump for 3 weeks, my A1c dropped half a point, so obviously it’s helping. I’m optimistic that the number will be even lower at my next appointment.

Is the pump perfect? No. There are a number of annoying features and issues that happen. But that comes with being an early adopter of a new technology. Am I glad I went through all the waiting and headache to switch? Hell yea! Even with its issues, I can see the positive effect this pump is having. And some of it is still user error. I’m sure my numbers would be even better if I remembered 100% of the time to prebolus my meals and improve other habits.

As someone reminded me, it’s not a magic pill (or pump) that’s going to suddenly make every blood sugar perfect. It’s still a piece of technology that has made advancements, but still requires effort on my end too. With that in mind, I’m eager to see what happens in the next 3 months.

  1. Thanks for the update. I go for my first training tomorrow. And I guess auto-mode starts next week. I’m expecting the start to be rocky but I’m hopeful it will improve a bit with each week.

  2. Tx for the review. I wonder if when the system gets locked into endless calibration woes, can you resolve it by stopping and restarting the sensor?
