New one-bean baselines

On Tuesday I had my six-week post-nephrectomy follow-up – a quick meeting with the coordinator and the surgeon, and a blood draw to establish my new one-kidney creatinine levels. I’ve felt 100% back to normal since about week 4! These are good numbers so I’m pleased.

Creatinine (mg/dl)

Important side-note: you will often see two EGFR (estimated glomular filtration rate) values, “African-American” and “non-African-American.” This “race correction” is bad science and is one of the many ways the health care system disadvantages people of color, especially black patients, who spend longer on the waitlist if it is used in the algorithm. The Institute for Healing and Justice in Medicine has a helpful toolkit for learning more and helping to end this bias.

To accompany this bloodwork baseline, I timed a one-mile run on the nearby Smith College track. I’ve done this several times over the years but I haven’t properly kept track (pun not intended!) The last time would have been within the past couple of years and I’m certain it was over 10 minutes; a decade or two ago it was under. Normally I use annual races as my benchmarks. I miss them very much; I did run a virtual 5K in August, but it’s hard to keep the pace of a real race. I was over 50 for my fastest 5K ever, where my mile time would have been around 9 1/2 minutes, but that’s race conditions and downhill.

I was a little surprised not to break 11 minutes, especially because I’m at the low range of my normal weight. I’m definitely slowing down with age, which is to be expected, but maybe even though I’m feeling totally healed, my running has room to come back? This Runner’s World article indicates that from 40 to 70, most runners slow down by about 1% per year. I’ll try to do this timed run on a monthly basis.

I mostly don’t mind aging at all. I keep growing as a person and getting better at dealing with life; each decade I’ve become happier and more fulfilled. But it’s an adjustment to acknowledge that I’m no longer competing with myself, expecting to get faster and stronger over time; now I’m racing the aging process, which will always catch up. My goals have to change to flattening the downward curves – appropriate for the pandemic world.

The really exciting news from this week is that I am now in touch with my recipient via email! Needless to say I won’t share any details in public, but I am so delighted to have a direct connection now. I hope we get to meet in person some day!
