Unfortunately, the body can also overreact to stressors that are not life-threatening, such as traffic jams, work pressure, and family difficulties. The carefully orchestrated yet near-instantaneous sequence of hormonal changes and physiological responses helps someone to fight the threat off or flee to safety. This combination of reactions to stress is also known as the "fight-or-flight" response because it evolved as a survival mechanism, enabling people and other mammals to react quickly to life-threatening situations. A stressful incident can make the heart pound and breathing quicken. It is important to note however that not all adrenal problems are caused by the gland itself and thorough examination and testing must be performed to determine the root cause.Chronic activation of this survival mechanism impairs healthĪ stressful situation - whether something environmental, such as a looming work deadline, or psychological, such as persistent worry about losing a job - can trigger a cascade of stress hormones that produce well-orchestrated physiological changes. When an adrenal gland begins to malfunction, either secreting too much, or too little hormone, the effects can be significant – causing a wide range of symptoms.
Epinephrine activates the fight or flight response. Epinephrine (adrenaline), a commonly secreted hormone during times of stress.The medulla or inner potion of the adrenal glands secretes Testosterone, a steroid hormone secreted in small amounts from the adrenal gland that helps regulate sexual function and offers other protective benefits.Aldosterone, a steroid hormone that largely regulates blood pressure and plays a key role in heart and kidney health.This hormone suppresses the immune system to prevent excess inflammatory response Cortisol, a steroid hormone that is most commonly activated during times of stress.The cortex, or outer portion of the adrenal gland, is divided into layers that secrete individual hormones such as:
Our adrenal glands serve an important purpose, regulating several hormones that play an essential role normal bodily function.
Adrenal glands measure about 1” by 3” and one is located above each kidney. The adrenal glands are small, triangular glands located above the kidneys.
