Basal Adjustments

Scott Benner

I was asked on FaceBook to explain how I made the adjustment to Arden's overnight basal rates that resulted in the graph above. I'm sorry that it took me so long to write about my (less than technical) process. Here's how I did it...

Somewhere around the second week of overnight lows it became obvious to me that I was dealing with a trend and not an anomaly. Something had changed about her physiology and I was going to have to adjust - basal adjust.

I'm not going to lie, I didn't do any basal testing. I have the procedure around here somewhere, the page or so of directions from Arden's endo that explains how to do basal testing - but I tried a more, let's say, personal approach. Luckily CGM technology lends a distinct advantage and unless we are averting a low, Arden doesn't eat at this time of night so trend graphs are a perfect way to understand where we have too much basal insulin.

I broke out the stupid PC laptop that we had to buy, because the damn device manufacturers refuse to port their software over to OS X (Apple), then I downloaded Arden's DexCom data. It only took a moment to see what time of night that her blood glucose was drifting lower.

Arden's overnight basal rate was .30 per hour, all I did was dial it back to .20 starting one hour prior to when her BG was beginning to fall, not terribly scientific I know. The possibility that this adjustment would be too little or too much wasn't a huge concern, because let's face it, I'm awake anyway.

As you can see in the image above, the slow drift that was beginning around 4 am leveled off nicely. The picture you see here shows that there was room for a little more basal insulin. I waited two more nights to verify that this graph was accurate and then I moved the basal to .25 an hour. That adjustment caused a slight dip and so the next night I staggered the hourly rates .20, .25, .20, things have been golden since.

The reasons that I like handling basal adjustments myself are simple. Waiting until Arden's next endo appointment to discuss this doesn't feel like an option - too long. Continuing to live with lows would have not only taken the rest of the precious little energy that I have left, but also it would leave Arden in danger - not doing that. People living with diabetes will always need to make adjustments like this. Their bodies, like everyone else's, are constantly going through ebbs and flows. My pancreas doesn't secrete the exact same amount of insulin every hour and it makes sense that Arden's pump shouldn't either. Arden's body has needs, ever changing needs - I have to keep up with them.

We all have to be comfortable making decisions like this autonomously at some point. As parents we don't always have the time to call for an army of help and our children's bodies shouldn't have to wait days or weeks for balanced control. Don't get me wrong, I wouldn't make a grand change to Arden's care without our doctor and I don't chase every night that doesn't go perfectly, but basal adjustments when they obviously are needed... We can do that!

If you are going to make basal adjustments please don't forget to write down your old numbers in case you have to switch back. Actually, if you don't already have that information recorded somewhere, take a moment to do that. Write down basal rates, IC ratios, alarm thresholds and all of the other personally inputted data that your pump and glucose monitors retain, just to be safe.

Later this week I'll be talking about Pre-Bolusing, Arden's latest A1c and more... stop back, like Arden's Day on FaceBook or follow the RSS feed to stay in the loop.

Good luck getting those basal rates where they need to be and then enjoy the huge difference in your BGs!
