How dangerous are the physical symptoms of a panic attack-when I have one I feel like I could die?

Assuming it IS just a panic attack, there's no reason to be afraid! Unless you have other severe health conditions (like a heart problem) you're totally fine! Source: http://www.calmclinic.com/panic/attacks/can-panic-attacks-kill-you

I am not a doctor and am providing my opinion based on experience. Almost always, the symptoms of a panic attack are temporary and minor. However, it is always best to have regular checkups with your doctor, and to discuss any symptoms that you experience during a panic attack. Feeling like we could die during a panic attack is very common. If you have insurance, often times there is a benefit that allows you to speak to a nurse 24/7 for free by calling the number on the back of your insurance card. If there is ever a doubt, especially if you experience chest pain, confusion, or dizziness, contacting emergency services or a trusted friend or family member is best.

They are not particularly dangerous by themselves. When coupled with other factors like drugs, crowds, or dangerous objects, however, they can be quite dangerous.

Sometimes individuals who experience panic attacks tend to think that they are worse than they actually are. For example, your heart rate increases because you're scared, but you think that you're having a heart attack instead.

Panic attacks lead to increased heart rate, and hyperventilating - worst-cases scenarios it will only lead to passing out thankfully

Everyone is different. There is no one answer fits all. If you feel like your in a situation that requires attention or out of the ordinary for you seek help from a medical healthcare professional.

Hyperventilation is a common symptom with panic attacks, this could cause you to faint because of lack of oxygen.

A panic attack normally does not hurt you as much physically then it does mentally. Unless you are the type that gets a panic attack and hurt your self in the process.

Panic attacks trick you into thinking you're in danger and they can be very scary, but once you take control of your breathing and return to a calmer state, there is usually no lasting damage to your health!

you need to learn yourself, and you need to learn what you need to do to try and control these attacks, you need to know what relaxes you or what helps you get through stressful times and when you feel like you're about to have a panick attack just breathe and try and do or listen to something that you know will make you feel calm.
