High levels of epinephrine can be caused by: Producing adrenaline during stressful events that don’t require sudden activity is fairly common, but true, constant overproduction is rare. However, some people have high levels of adrenaline even when there is no danger present. In most cases, adrenaline is only needed for those periods of stress. The sudden increase is normal and subsides after the stress has faded.


In times of severe stress, epinephrine is released at high levels.

In different types of adrenal tumors, other hormones are over-produced, including cortisol, aldosterone, and androgens. This over-secretion of epinephrine can lead to a dangerous and severe elevation in blood pressure. In the case of pheochromocytoma, the hormones produced are epinephrine and noradrenaline. Adrenal tumors, some called pheochromocytoma, can cause too much adrenal hormones to be produced. Addison's disease is a severe or total deficiency of the hormones made by the adrenal glands, including epinephrine, cortisol, and aldosterone. The following health conditions are linked to epinephrine levels: The above responses help to prepare your body for a "fight or flight" reaction, making you ready for rapid, strenuous activity. When the hormone enters the bloodstream, the following will increase: This reaction, known as the “Flight or Fight Response” prepares the body for strenuous activity. Strong emotions such as fear or anger cause epinephrine to be released into the bloodstream, which causes an increase in heart rate, muscle strength, blood pressure, and sugar metabolism. The hormone is also necessary for maintaining a healthy cardiovascular system - it makes the heart beat more strongly, and diverts blood to tissues during times of stress. Your body naturally produces it during times of stress.

Epinephrine is commonly known as adrenaline.
