An Addisonian crisis is a severe, life-threatening medical emergency that develops due to adrenal insufficiency. Its symptoms include severe weakness, low blood pressure (hypotension), nausea, vomiting, abdominal pain, confusion, and fluid-electrolyte imbalance. Laboratory findings often show low sodium (hyponatremia) and blood sugar (hypoglycemia), along with high potassium (hyperkalemia). This crisis is typically triggered by stress-inducing conditions in the body, such as physical or surgical stress, trauma, or infection.
