Watching the Squiggles

It's the middle of the night in the MCC,
But on orbit early morning...GMT. 
ADCOs watch the squiggles with hawk-like eyes, 
With hopes of nice trends - no surprise. 

But on these special nights there's one more plot, 
It hangs out near the space data in its special spot. 
The readings don't come from the I-S-S, 
Their source has a 'within 20 feet' address. 

The user is an expert at detecting adverse trends, 
Night after night - even on weekends. 
Her pancreas is busted, but not her resolve, 
She's armed with glucose tabs - easy to dissolve. 

Diabetes doesn't come with a set of procedures,
The user is simply forced to deal with it's "features".
Everything can change from one day to the next,
It's the nature of the beast - Diabetes is complex.

But machine and disease DO share some traits,
i.e. Malfunctions are sometimes hard to correlate.
The initial response, however, is often the same,
First safe the system - don't worry about the blame.

Solving problems with logic is an engineer's work,
But applying logic to Diabetes can drive one berserk!
So we do the best we can, with our CGM squiggles,
Reacting to excursions - but it's just never that simple.

'Insulin on board' and 'glucose correction factors',
It feels more complicated than a fusion reactor.
The equations are simple, the theory quite clean,
But the unexplained fluctuations verge on obscene.

And when the squiggles are compared side by side,
It may be hard for a novice eye to recognize.
One set is a lifeless machine floating in space,
The other a mess of living cells ... part of the human race.

Even with this disease I'm alive, I'm alive!
And reading those pesky squiggles helps me survive.
I'm sure if she could, ISS would also thank me,
For watching all her squiggles - daily and nightly!
