Cramping's one of my symptoms; I'm being a bit coy. To be more blunt (the disease is Ulcerative Colitis), the main thing is bowel movements per day. At the moment, I've got an NFC tag sitting in the bathroom that I swipe to log a motion (as the path of least resistance)... but (as mucky as it sounds) I'd like to hack something together with an Arduino/Raspberry Pi and a weight sensor attached to the toilet, which could detect that I'm sitting down and log a movement for me automatically (in much the same way the Aria automatically logs my weight!).

This'd need to tie into a mobile app for manual logging anyway (I'm not exactly going to rig this up at work!) with a backing web service, but yeah. There's definitely room for something clever in this space :).

That's a really good idea. I could see a small Arduino board with wifi and a FlexiForce[0] (just the first thing that came up in Google for "Arduino weight sensor"), and like you said a mobile component that would either be a stopwatch to actually log or a time entry for past movements (or when you didn't have your phone, etc).

My sister has Crohn's and one of college roommates had UC so I'm somewhat familiar with it.

My contact info is in my profile if you want to talk about this more.
