Adrenal Insufficiency Physiology
Adrenal Insufficiency Aldosterone
Aldosterone causes the body to retain salt, which in turn causes the body to retain water. This increase in water can raise blood pressure.
Adrenal Insufficiency Cortisol
- Helping the body supply nutrients needed during times of stress
- Maintaining blood pressure and heart function
- Regulating the body's use of protein, carbohydrate, and fats
Adrenal Insufficiency Epinephrine
Epinephrine stimulates the nervous system, helps maintain blood pressure, and increases the heart rate. Epinephrine is released into the bloodstream when the blood glucose is low, and during times of intense exercise and stress.
Adrenal Insufficiency Norepinephrine
Norepinephrine helps to maintain the blood pressure, but has little effect on the heart.
