what is an addisonian crisis
1 An Addisonian crisis is a serious medical emergency caused by extremely low levels of cortisol. Cortisol is an important hormone produced by the adrenal glands and is normally released as part of the bodyâs response to stress.  People with Addisonâs disease are at the greatest risk of developing an Addisonian crisis. Addisonâs disease occurs when the adrenal glands donât produce enough cortisol. The condition can cause extreme weakness, confusion, vomiting, and a big drop in blood pressure.
