What causes panic attacks with hyperventilation?

Try Relax Breathing: Hyperventilation can be one of many symptoms of panic disorder. I highly recommend the book: the relaxation response by benson. Read the entire book, then start doing the exercises as contained in the book. Start with 5 minutes twice a day working up to 10 minutes twice a day. You will soon learn to relax instantly, anytime you want or need to, like in the car. It's not hard. Good luck.

Panic: Usually there are no clear triggers for panic attacks. Finding good therapist that works with cognitive behavior therapy will help u explore the dynamics underlying your anxiety, and eventually concur the attacks.
