@Miller,
Yes - the urine test was for traces of blood in the urine or something else I can't remember but I think it was blood and not drug testing. It only cost us $20 but if we didn't have a discount due to insurance (now this isn't insurance paying but because we have it we do not get charged full price) - it would have been $254 - crazy huh.
Basketball doesn't normally make her sick - it was just that the gym was so hot and she played too long for her current physical stamina. Normally she can play pretty close to an entire game. She had been out for a few weeks with limited physical running due to her sprained ankle. This was the first full game she played.
My older daughter went through this at one point too. She would be playing hard - come out and throw up, have some water and then go in again after a few minutes. The doctor suggested giving her ensure in the mornings when she had games so she would have nutrients but nothing that would be heavy where she would get sick. It worked for her.
This is only the few times it happened with this child - and the last time it was the first game coming off an injury - after a week of being able to run and build up again she was fine.
Honestly you see competitive athletes do this frequently. They work out so hard the puke. My friend told me how this happened with many of the hockey players her son played with they would skate running like suicides you do in basketball until many would get sick - then a week or two into the season they would have the stamina to keep up without getting sick.
In my opinion not the best way to get in shape, but you do see it with competitive athletes. If she were to continue getting sick when playing then yeah, I would have her slow down and not play so many minutes, but it so rare and it isn't anyone pushing her - she wants to go back in.
