A member asked:

Lab work all came back normal. what are some causes of becoming lightheaded? it can happen randomly but most often during exercise.

A doctor has provided 1 answer

Heart?: I would expect lab to be normal. I would be more concerned about your ekg, listening to your heart and in performing a cardiac echo and event monitor. Cardiac dysrhythmia of some sort may be your culprit. If not could be dehydration or anxiety.
