Located just above each kidney, these glands produce many hormones such as cortisol and adrenaline, which are necessary for the proper functioning of the body. How to recognize a malfunction? What diseases can they cause?
These glands produce many hormones such as cortisol and adrenaline, necessary for the proper functioning of the body. They are two in number and each “cap” a kidney. They consist of two superimposed parts: on the periphery, a yellow zone called “adrenal cortex” or “adrenal cortex” and, in the center, a red nucleus called “adrenal medulla”. Each of these two areas specializes in production of hormones essential for life.
The adrenal glands are responsible for synthesize and release many hormones into the bloodstream essential for the proper functioning of the body.
► The adrenal medulla secretes norepinephrine and adrenaline, two hormones that speed up the heart rate and increase blood pressure. They are more particularly produced in times of stress.
► “The adrenocortical part produces hormones called “corticosteroids” (Cortisol), mineralocorticoids (Aldosterone), and androgens (Testosterone and DHEA sulphate), explains Dr. Pierre Nys, endocrinologist in Paris. Among them, cortisol which participates in the regulation of blood sugar and has an anti-inflammatory action, testosterone (in partnership with the gonads) a male sex hormone which is involved in sexual development and reproduction, and aldosterone whose role is to control sodium retention and potassium leakage, thus regulating blood pressure.
“There are more than 20 diseases linked to dysfunction of the adrenal glands”, says Dr. Nys. Among :
Dysfunction of the adrenal glands causes different symptoms:
To detect dysfunction of the adrenal glands, the doctor first performs a clinical examination via an interrogation of the symptoms felt. “Blood and urine tests can be carried out to analyze the level of certain hormones in the body. A drug treatment will be prescribed to you according to the hormone to be compensated”, explains Dr. Nys.
