summers explains it this way. “you kind of age before your time. i’m 53, but my blood vessels are probably similar to someone who is in their 70s.”
at one time, summers had to prick her finger to check her blood sugar levels at least three times daily and inject herself with insulin before eating anything containing carbohydrates (which break down into sugar). while today, she is fortunate enough to have access to wearable devices that simplify those processes somewhat, the time commitment and mental workload are still considerable.
for instance, even with a continuous glucose monitor (cgm) and insulin pump, every time summers eats anything, she must calculate the grams of carbohydrates the food contains and adjust her insulin dosage accordingly. and that can be difficult.
say you’re served potato as a dinner guest. since you can’t weigh it, “you’re going to eyeball it, and the more you have to estimate things, the more chances you’ll foul it up,” summers explains, leading to blood sugar levels that are either too high or too low.
similar fluctuations can happen even when your math is perfect. factors like viral infections, trauma, surgery and stress can all cause blood sugar levels to skyrocket. toughened skin due to repeated jabs can interfere with insulin absorption — and therefore, blood sugar regulation — too.
