The most common cause of primary adrenal insufficiency (Addison's disease) overall is autoimmune adrenalitis. [2] The prevalence of Addison's disease ranges from 5 to 221 per million in different countries. [30] In children, congenital adrenal hyperplasia (CAH) is the most common cause of adrenal insufficiency, with an incidence 1 in 14,200 ...
Often categorized under euvolemic is hyponatremia due to inadequate urine solute (not enough chemicals or electrolytes to produce urine) as occurs in beer potomania or "tea and toast" hyponatremia, hyponatremia due to hypothyroidism or central adrenal insufficiency, and those rare instances of hyponatremia that are truly secondary to excess ...
In secondary adrenal insufficiency, hyponatremia results from decreased kidney excretion of electrolyte-free water and the inability to suppress vasopressin. [5] Hyponatremia in primary adrenal insufficiency is caused by concurrent aldosterone deficiency, resulting in volume depletion, natriuresis, and hyperkalemia. Hypercalcemia is triggered ...
Although hyponatremia is a fairly common condition, many patients have only mildly decreased blood sodium. Dr. Jeff Hersh explains the cause of hyponatremia, and how it should be treated Skip to ...
Hypoaldosteronism causes low sodium (hyponatremia), high potassium (hyperkalemia), and metabolic acidosis, a condition in which the body produces excess acid.These conditions are responsible for the symptoms of hypoaldosteronism, which include muscle weakness, nausea, palpitations, irregular heartbeat, and abnormal blood pressure.
Pale skin may contribute to patients' diminished appearance and aid in differentiating between primary and secondary adrenal insufficiency. Secondary adrenal insufficiency is not associated with a lack of aldosterone, so symptoms and signs of mineralocorticoid deficiency, such as salt craving, postural hypotension, and electrolyte abnormalities ...
Adrenal hemorrhage characteristic of the Waterhouse–Friderichsen syndrome has been identified in several autopsies of patients who died of sepsis secondary to capnocytophaga canimorsus infection. [8] Viruses may also be implicated in adrenal problems: Cytomegalovirus can cause adrenal insufficiency, [9] especially in the immunocompromised.
Adrenal gland malfunction can present acutely or chronically. In a more chronic case, it is similar to Addison's disease with symptoms including fatigue, weight loss, hypoglycemia (low blood sugar levels), low hemoglobin levels (anemia) and hyponatremia (low sodium levels) that develop over several months or years.
