What is Addison disease?
Addison disease is a condition that can cause people to have low blood pressure, lose weight, and feel tired and weak.
Addison disease occurs when the body's adrenal glands do not work normally. The adrenal glands are small organs that are located on top of each kidney. Normally, the adrenal glands make substances called hormones. These hormones do many things in the body, such as help keep blood sugar levels and blood pressure normal. In people with Addison disease, the adrenal glands do not work properly and do not make enough hormones. This causes symptoms, which sometimes can become severe and even life-threatening.
