When Joseph's endocrinologist enters the exam room wearing a serious expression, I know I'm about to face the reality behind a growing fear.
It was all those damn highs, of course-- no matter how hard we tried, we just couldn't seem to get on top of them.
"Hello-- well, Joseph's A1c has gone up," she says as she holds out a white sheet of paper with a number handwritten at the top.
8.2
"Now, we're going to make some basal changes. Joseph's been getting far less basal insulin than he needs-- he should be getting at least 50% of his total daily dose as basal, and that hasn't been the case."
I want to say that it's been this way because when we've raised his rates before, he's gone low.
But I say nothing.
"While Joseph still takes in far less insulin than is typical for a child of his age, height and weight-- normally that would be between 35 and 45 units per day, and um... looks like he's taking in about 17 -- we really want to get him to where he should be with his basals. I think that will help smooth out some of these highs."
I nod in silent agreement, but my mind is still grappling with that number and what it implies.
He was 7.5 at the last visit.
"Sandra, I'd like to increase his rates at noon, 2 and 6 PM."
I stare down at the sheet of paper listing Joseph's new basals.
My God, she's got him at .300 from noon to 2pm. And .225 at 2pm? That's so high... and he's always so active then.
But again, I say nothing.
"I want you to try these rates for the next few weeks, and then we may want to increase them some more until we get that basal up to at least 50% of his total daily dose."
A few weeks? But he's going to camp at the end of the month.
Feeling utterly helpless, I suddenly remember something vital.
"Doctor Connor, how was Joseph's growth?"
"Oh, it was terrific, let's see," she says as she pulls out the percentile chart. "He gained over a pound since the last visit, putting him in the 50th percentile for weight-- which has always been his curve. And he grew over an inch-- which is wonderful. So he's right between the 50th and 75th percentile in height. Oh, and he's got a lot of lean muscle mass-- just what we like to see."
Relieved that Joseph's growth is on track, but still shaken by the rise in his A1c, I ask questions about the Dexcom CGMS and Exubera (the new inhalable insulin). By the time we begin discussing my concerns about diabetes camp, I begin feeling that I can still do this.
That I really can take of my son.
And so we leave our appointment and implement Joseph's new rates starting at noon. At 2:30 PM, his blood sugar drops to 65, we treat, and fifteen minutes later, he's 62.
The rebound later peaks at 344.
On Tuesday, his afternoon blood sugars are definitely more in range-- in fact, four hours after his breakfast bolus, he's 78.
But it's raining, and he's not being active today. At all.
And still he has a low at 8:30 PM.
His numbers are good again early on Wednesday, but only after I decrease his insulin to carb ratio, and have him eat some extra carbs during the day. But then, he goes low at 6:40, 9:30, and 10:40 PM. The latter bg was 57 -- prompting a rebound in the mid 300s for several hours.
And now, I'm feeling so unsteady here. Like I'm no longer capable of really knowing how to respond to all of these numbers.
You see, I was afraid that his A1c would rise, and it did.
But I really thought we were doing all right.
Now I just don't know anymore.
