If left untreated, obstructive sleep apnea can increase the risk of high blood pressure, diabetes, and atherosclerosis due in part to chronic overproduction of adrenaline. Obstructive sleep apnea: This chronic sleep disorder, which causes the momentary disruption of breathing, can indirectly cause adrenal hypersecretion by triggering a stress response as you gasp for air.A type of tumor called a pheochromocytoma affects cells responsible for producing adrenaline, leading to the overproduction of adrenaline. The tumors are usually benign (non-cancerous) but can sometimes be cancerous. Adrenal gland tumors: Tumors of the adrenal glands can also cause the overproduction of adrenaline and cortisol.Common causes include the prolonged use of corticosteroid (steroid) drugs and pituitary gland tumors. Adrenaline, cortisol, and aldosterone are all produced by the adrenal glands, while the release of the hormones is regulated by the pituitary gland in the brain. Cushing syndrome: This is a disorder that causes the overproduction of the stress hormone cortisol and the related stress hormones adrenaline and aldosterone.
