As a kid our dog got into my crayons. Kids from all over the neighborhood came by to look at the rainbow colored dog logs in the yard.
Ah, the days before video games.
As for OP, I'm not a doc, but in my case, the white stools were the result of gallstones clogging up the biliary plumbing. I have a very high pain threshold and had been writing off the occasional gall bladder attacks as indigestion for more than a decade. But when the mother of all gall bladder attacks kicked in, it knocked me to the floor -- literally -- for more than a day.
I would have called an ambulance, but I was unable to get up off the floor to get to the phone. I spent the time writhing in pain, alternately wishing that I could die and being afraid that I would very soon. We're talking some serious pain. I wouldn't have wanted to be in the cockpit when that happened, that's for sure.
In retrospect, it's obvious to me that the gallstone symptoms had been around for about 15 years. But the pain had never seemed subjectively bad enough for me to do anything about it besides taking an Alka-Seltzer. Because the Alka-Seltzer contains aspirin (which does in fact help smaller gallstones to pass), it would usually relieve the pain, so I never gave the possibility of a gall bladder problem much thought. The pain just didn't seem "bad enough" for me to think along those lines.
The years of mistaking gallstones for indigestion also led to pancreatitis. In fact, the inflammation was bad enough that the docs were concerned about pancreatic cancer based on the pre-surgical scans. Even after removing my gall bladder (which the surgeon described as looking like "a sweat sock full of marbles") and doing a biopsy, they still insisted on a post-surgical MRCP to confirm that the pancreatic inflammation was subsiding.
Long story short, if the white stools happen even once more, or are preceded or followed by even a twinge of pain, I'd suggest paying a visit to your doc very soon after. It could be nothing, but it could also be an early symptom of a gall bladder problem. I suppose it could be many other things, too. I'm not a doctor. But based on personal experience, I wouldn't ignore it if it happened again.
By the way, gall bladder removal is aeromedically insignificant once the surgery heals.
