Adrenal gland disorders (or diseases) are conditions that interfere with the normal functioning of the adrenal glands. [1] Your body produces too much or too little of one or more hormones when you have an adrenal gland dysfunction. The type of issue you have and the degree to which it affects your body's hormone levels determine the symptoms.
Adrenal glands, anterior (left) and posterior (right) surface. The adrenal glands are located on both sides of the body in the retroperitoneum, above and slightly medial to the kidneys. In humans, the right adrenal gland is pyramidal in shape, whereas the left is semilunar or crescent shaped and somewhat larger. [8]
Adrenal insufficiency is a condition in which the adrenal glands do not produce adequate amounts of steroid hormones. The adrenal glands—also referred to as the adrenal cortex—normally secrete glucocorticoids (primarily cortisol ), mineralocorticoids (primarily aldosterone ), and androgens .
There are rare conditions that lead the adrenal glands to either under- or over-produce hormones—Addison’s disease and Cushing’s syndrome, respectively—but they’re usually caused by ...
Waterhouse–Friderichsen syndrome (WFS) is defined as adrenal gland failure due to bleeding into the adrenal glands, commonly caused by severe bacterial infection. Typically, it is caused by Neisseria meningitidis. [1] The bacterial infection leads to massive bleeding into one or (usually) both adrenal glands. [2]
Hypoadrenalism, or adrenal insufficiency, is a condition indicated by the underproduction of hormones that are related to the adrenal glands. Underactivity of the adrenal gland is also caused by the adrenal glands, or by other systemic dysfunctions, leading to insufficient production of hormones.
Emergencies arising from decompensated pheochromocytomas or parathyroid adenomas are sometimes referred for emergency resection when aggressive medical therapies fail to control the patient's state, however the surgical risks are significant, especially blood pressure lability and the possibility of cardiovascular collapse after resection (due ...
Located within the adrenal glands are the three zones that are responsible for secretion of the three major classes of adrenal steroids. Hence, functional adrenocortical adenomas can induce over-secretion of adrenal steroids associated with pure or mixed endocrine syndromes, a condition commonly known as hyperadrenalism.
