What hormones are affected by Addison’s disease?

Addison’s disease is caused by damage to your adrenal glands, resulting in not enough of the hormone cortisol and, often, not enough aldosterone as well. Your adrenal glands are part of your endocrine system.

What happens when ACTH is low?

A decline in the concentration of ACTH in the blood leads to a reduction in the secretion of adrenal hormones, resulting in adrenal insufficiency (hypoadrenalism). Adrenal insufficiency leads to weight loss, lack of appetite (anorexia), weakness, nausea, vomiting, and low blood pressure (hypotension).
