What does a surge in adrenaline mean?

Adrenaline surge refers to a phenomenon in which the body rapidly responds to strong external stimuli, such as fright, fear, vigorous exercise, or emergency situations, by quickly secreting large amounts of adrenaline, leading to a sharp increase in adrenaline levels. This secretion is directly regulated by the nervous system and serves as a self-protective mechanism of the body. A significant release of adrenaline can enhance myocardial contraction, accelerate blood circulation, increase cardiac output, constrict blood vessels, and improve the body's ability to cope with potential dangers or emergencies. If adrenaline levels remain elevated for a prolonged period, it may trigger various health problems such as hypertension, hypokalemia, dizziness, headache, and weakness in the limbs. In such cases, timely medical evaluation and appropriate treatment measures are necessary.
