- Lack of completeness of function or power. SEE ALSO: incompetence. [L. in-, neg. + sufficientia, fr. sufficio to suffice]- acute adrenocortical i. severe adrenocortical i. when an intercurrent illness or trauma causes an increased demand for adrenocortical hormones in a patient with adrenal i. due to disease or use of relatively large amounts of similar hormones as therapy; characterized by nausea, vomiting, hypotension, and frequently hyperthemia, hyponatremia, hyperkalemia, and hypoglycemia; can be fatal if untreated. SYN: addisonian crisis, adrenal crisis, Bernard-Sergent syndrome.- chronic adrenocortical i. adrenocortical i. usually as the result of idiopathic atrophy or destruction of both adrenal glands by tuberculosis, an autoimmune process, or other diseases; characterized by fatigue, decreased blood pressure, weight loss, increased melanin pigmentation of the skin and mucous membranes, anorexia, and nausea or vomiting; without appropriate replacement therapy, it can progress to acute adrenocortical i..
