High adrenaline secretion may be caused by physiological factors, traumatic stress reaction and pheochromocytoma. 1. Physiological factors: when the patient is under too much pressure, frequently staying up late or emotionally agitated and nervous, it may lead to a corresponding increase in adrenaline secretion. 2. Traumatic stress reaction: when the patient is hit by external forces, a stressful reaction will occur. During the reaction, the patient’s mind and body may suffer certain injuries, which may cause abnormal hormone secretion in the body, leading to excessive adrenaline secretion. 3. Pheochromocytoma: Excessive adrenaline secretion may be caused by pheochromocytoma, which originates from the adrenal medulla and will lead to abnormal secretion of adrenaline and excessive adrenaline. There are many reasons for hyper adrenaline secretion, patients should go to the hospital in time, under the guidance of doctors for reasonable treatment.
