Hi. I've recently been expereincing weird sensations like suddenly losing awareness or momentarily losing balance. Its happened about 5 or 6 times.?

Possible TIA. This could be TIA like symptoms. I suggest you see your doctor and have the following performed: ekg, tsh, echocardiogram with bubble and contrast, lipid panel and carotid doppler study. He will also check your blood pressure. You do not want to have stroke. Take a chewable Aspirin until you find out. Could also be a heart arrhythmia that may need holter to identify; or may show up on ekg.
