My grandaughter has just started playing field hockey and she claims she gets dizzy and shaky.  She actually got sick the first week and vomited, etc.  We are taking her to the drs. tomorrow, but we trying to figure out if we should continue to let her play or just not play at all since it is such a short season.
Hello, Thank you for trusting Chat Doctor.It's great that you are keeping a close eye on your granddaughter, it's not field hockey in specific that might cause this, but exercise intolerance in general, please take her to a doctor for physical examination, you didn't mention her age which help in understanding the case more, this might be due to anemia, diet, It's hard to say with the current provided info, but since you are going to doctor I hope he or she will be able to clarify things more to you. Best regards,
