Abstract
Endocrine emergencies represent a group of potentially lifethreatening
conditions that are frequently overlooked. They include:-
Diabetic emergencies: (most common endocrinal crisis)
Diabetic ketoacidosis(DKA):
DKA is a complex disordered metabolic state characterized by
hyperglycemia, ketoacidosis, and ketonuria. DKA mainly occurs in
patients with type 1 diabetes. Many complications may occure in DKA
either from the disease it self or from treatment.
Hyperosmolar hyperglycemic state (HHS):
HHS most commonly occurs in patients with type 2 diabetes
mellitus. Most patients present with severe dehydration and focal or
global neurologic deficits, detection and treatment of an underlying
illness are critical. In general it is close similar to DKA.
Hypoglycemia coma:
is a reversible form of coma found in people with hypoglycemia.
Pituitary apoplexy:
Hemorrhage or infarction of pituitary gland mostly pituitary
adenomas causing suppression of hormones secretion leading to
hormonal deficiencies.
Thyroid gland emergencies:
Thyroid storm:
Thyroid storm is almost fatal if left untreated. So rapid diagnosis
and aggressive treatment are critical.

Myxedema Coma:
The condition occurs in patients with long- standing, untreated
hypothyroidism. The first 24-48 hours are critical. If the diagnosis is
considered, immediate and aggressive treatment to lower high rate of
mortality.
Parathyroid gland disorders: - Hypercalcaemic crisis
- Hypocalcaemic tetany
Adrenal gland emergencies:
Pheochromocytoma:
It is a catecholamine or their metabolite-secreting tumor,
Catecholamines typically secreted, either intermittently or continuousl,
include norepinephrine and epinephrine, rarely, dopamine is secreted.
Acute adrenal insufficiency:
It is an extreme life-threatening it should be suspected in patients
with unexplained hypotension and fluid or catecholamine-resistant
hypotension.
