Why does sustained exercise sometimes make me very unwell for hours or even days? I lift heavy weights at the gym three times a week with no problems, I get enough sleep, I eat very healthily (but perhaps my intake is low on carbs like bread, pasta or rice). But every now and then, when I do a sustained cardio type exercise for about an hour or a little more (playing a sport, taking occasional breaks for water, etc), I start to feel fatigued before everyone else does, then I feel extremely sick to the point of having to sit down, not wanting to move. In extreme cases, I've been unwell for more than two entire days after.

I thought it might have been lack of pre-exercise nutrition, but today I had a great hearty meal with plenty of protein, a little bit of carbs and some vegetables about an hour an a half before, and yet it still happened.
Is it likely to be dehydration? I was pausing to drink water, and the exercise itself wasn't very strenuous at all, but it was sustained for more than an hour. I had a Gatorade afterwards, and I felt better, but I don't know if those two have any causality; it may have just been the passing of time.
I looked at these previous threads:
but none seemed to be exactly what I'm experiencing. Any suggestions? Thank you.
