I can't remember the exact numbers of time he collapsed. But I'm pretty sure that there was once where he broke his leg, and another when he was too tired, another where he was too stressed (I think it was around the beginning of GO) since Fifth Sector was banning soccer, but Tenma still wanted to play and rebel, and he had to take care of the team and stuff, and everyone was depressed and angry with Tenma. And there were also other times when the enemy tackled or hurt him. I don't think its a sickness. Its pretty unlikely, he seems quite healthy.
