    I occasionally exercise *shock horror* ;)

    I have noticed however that whenever I do a reasonable level of exercise (that 98% of the population would take for granted), that my urine is dark with a brownish tinge. Not nearly as dark as the image on Wikipedia, but heading in that direction:

    The colour is likely due to a breakdown of muscle products. I am wondering if this is common among people with ME or CFS?

    I always have trace amounts of blood in my urine, since I got sick. No idea if it would get more noticeable if I were to push my limits. I assumed mine was due to chronic inflammation.

    I've had trace amounts of blood in my urine since getting this illness too. After getting
    a kidney stone that was too big to pass I decided this was probably from passing tiny stones on
    a regular basis. I have a leaky gut and oxalate problems so it made sense. I didn't realize
    this was a marker for chronic inflammation.

    On the dark urine, mine is dark unless I drink lots and lots of water.

    Having seen patients with rhabdo, I kind of dismissed this when I first read it, but on further reflection I am wondering if you aren't on to something. Maybe a mild form of rhabdo from muscle breakdown occurs?

    This summer when I was doing better and was quite active and pushing exercise, even though I was drinking a lot and getting IV saline regularly, my urine was always very dark. Now that I've relapsed and am mostly back in bed, I'm not able to drink as much, have stopped the saline and my urine is light and clear.

    When I have over-exerted I get what appears to be osmotic diuresis, followed by apparent symptoms of mineral deficiency. I had an unusually-bad episode in the past week, which gave me a very bad night as I was having to get up so frequently, and passing a lot of urine so getting dehydrated. It is part of my PEM, and the urine is definitely more concentrated than usual, sometimes a bit cloudy, but not brown, although I had that once or twice in the early stages.

    The two episodes of severe hyponatraemia I have had were probably a result of repeated over-exertion.
