What causes panic attacks?

The cause of panic attacks can be physiological (e.g. exercise, drinking strong tea and coffee, etc.) or pathological (e.g. hyperthyroidism, arrhythmia, etc.), and needs to be analyzed specifically.
1. Physiological: exercise, drinking strong tea and coffee can make the sympathetic nerves excited, palpitations, that is, what we call panic attacks, can be relieved after resting, need to avoid excessive exercise and drinking strong tea and coffee, so as not to cause discomfort.
2. Pathological: hyperthyroidism when the sympathetic nerve excitation, can cause sinus tachycardia, will make people feel panicky, can also be accompanied by sweating, easy to starve and other symptoms, thyroid function tests can be clearly diagnosed; arrhythmia (such as sinus tachycardia, premature beats, etc.) can appear when the heart is difficult to panic, electrocardiography and other tests can assist in the definitive diagnosis.
There are many reasons for panic attacks, if they do not get better or continue to worsen except for physiological factors, it is necessary to consult a doctor in time to avoid delaying the condition.
