Adrenal Glands: Hormones for Stress

Today we travel southward to the adrenal glands. Perched on top on the kidneys, these glands are broken down into two parts. The outer part, the adrenal cortex, produces essential hormones to life, whereas, the inner part, the adrenal medulla, produces hormones that aren’t necessary for life. The cortex produces 2 groups of corticosteroid hormones:

  • glucocorticoids (ones triggered by the hypothalamus and pituitary gland)
  • mineralcorticoids (released in response to the kidneys)

Glucocorticoids include:

  • Hydrocortisone (commonly called our one our favorite topics-cortisol) not only regulates the conversion of macronutrients into energy, but also controls blood pressure and cardiovascular function
  • Corticosterone works with cortisol to regulate immune response and suppress inflammatory reactions.

Mineralcorticoids include:

  • Aldosterone is important for water and salt balance, as well as blood pressure control

The cortex, also releases, small amounts of sex hormones, but this is overshadowed by the gonads production of these hormones. Onward to the inner portion, the adrenal medulla. These hormones are released upon stimulation of the sympathetic nervous system (stress). These non-vital, but important still, hormones include:

  • epinephrine (aka adrenaline) increases heart rate and blood flow to the muscles and brain, and spikes blood sugar.
  • norepinephrine works in accordance with epinephrine, but can cause vasoconstriction (narrowing of arteries) and increases blood pressure.

Although adrenal disorders are rare, I have a special interest in them because my daughter has the auto-immune disease, Addison’s  (the body doesn’t produce enough cortisol, although, the problem is usually caused by the body not producing insufficient aldosterone. How do we keep these adrenals healthy? Same as the other glands that we have covered this week. Hormonally balanced eating and healthy lifestyle practices (reduced stress and quality sleep) to maintain optimal hormone regulation and production.
