There may be many reasons for anxiety attacks, but by some way the commonest one is that you've been concerned in or witnessed a dire or surprising experience. One which was life-threatening.

As an example, if you were badly abused as a child, you'll have learned that to be on continual alert could protect you from further abuse. But you can not stay in repeated alert all of the time. Your body can't handle that. So you remain anxious all of the time, but very so periodically.

The triggers might be an easy reminder of the sounds which happened before the abuse. Something as simple as closing a door.

Being involved in a bad accident is extremely life-threatening, so could cause them.

As is being told you have a potentially lethal illness.

The main thing to remember is that any shock or trauma is one of the likeliest reasons for anxiety attacks. And that you have became stuck in that shock or injury.

Not every one gets stuck in a shock, but because of the intensity and it is most likely fatal, many do.

But it is common not to recollect the cause it it was many years back. You have moved on, buried the experience as it was not helping you. But it still is waiting to be resolved. The attacks show that.

If you can not remember when they started, then pro help is suggested. And the speediest and gentlest help comes in the shape of homeopathy.

But you can also help yourself by taking the homeopathic medicine Aconite when you feel concerned. As this deals with the reasons behind anxiety attacks, the shock, the shock gradually, over time, they will lessen, perhaps disappear altogether.

A number of other considerations can also act as causes for anxiety that include genetic, biologic and medical. A number of studies have pointed to the fact that at least in half of those experiencing anxiety, have a close relative who has an anxiety disorder. Among the biologic causes, modifications in certain brain chemicals like serotonin, nor-epinephrine, and GABA are being investigated as having a link with anxiety.

Among medical causes of anxiety disorders, the chief causes are heart problems, tumors, endocrine disorders, neurological diseases and diseases.
