Adrenal Insufficiency

Adrenal insufficiency occurs when your adrenal glands do not function properly. Adrenal glands, which sit on top of your kidneys, produce many hormones. Cortisol helps your body respond to stress. Aldosterone affects the balance of fluid in your body.

There are two types of adrenal insufficiency:

  • Primary adrenal insufficiency, also known as Addison's disease, is due to the destruction of the adrenal glands by antibodies.
  • Secondary adrenal insufficiciency is usually caused by medications that eventually cause the adrenal gland to stop making cortisol.

Adrenal insufficiency symptoms

  • Feeling tired or weak
  • Weight loss
  • Decreased appetite
  • Abdominal pain
  • Patches of dark skin on the face, neck or hands
  • Dizziness

How can I get help for adrenal insufficiency?

See your primary care doctor if you have symptoms of adrenal insufficiency. Your doctor will perform a physical exam and order blood tests. You may also need an ACTH stimulation test to see if your adrenal glands are functioning properly.  If you have adrenal insufficiency, your doctor will refer you to an endocrinologist, a hormone specialist.
