Cushing's syndrome is a collection of signs and symptoms due to prolonged exposure to glucocorticoids such as cortisol. [4] [9] [10] Signs and symptoms may include high blood pressure, abdominal obesity but with thin arms and legs, reddish stretch marks, a round red face due to facial plethora, [11] a fat lump between the shoulders, weak muscles, weak bones, acne, and fragile skin that heals ...
The resulting excessive adrenocorticotropic hormone secretion led to the production of large amounts of cortisol by the adrenal glands. Considering this impact, the name of Itsenko was added to the title in some East European and Asian countries, and the disease is called Itsenko-Kushing disease.
Conversely, chronically elevated ACTH levels occur in primary adrenal insufficiency (e.g. Addison's disease) when adrenal gland production of cortisol is chronically deficient. In Cushing's disease, a pituitary tumor leads to excessive production of ACTH, which stimulates the adrenal cortex to produce high levels of cortisol.
ACTH then travels to the adrenal glands and induces the release of cortisol into the bloodstream. [7] In Cushing's syndrome, this process occurs in excess. Some symptoms of an individual with Cushing's syndrome include low tissue protein levels, due to muscle and bone atrophy, and high blood glucose levels. Sodium levels also see an increase ...
A lack of cortisol can result in a condition called adrenal insufficiency, which can cause symptoms such as fatigue, weight loss, low blood pressure, nausea, vomiting, and abdominal pain. Adrenal insufficiency can also impair the ability of the host to cope with stress and infections, as cortisol helps to mobilize energy sources, increase heart ...
Addison's disease, or primary adrenal insufficiency, is an uncommon chronic illness characterized by insufficient production of cortisol and aldosterone by the adrenal glands. [17] Chronic primary adrenal insufficiency is typically characterized by an extended period of malaise, fatigue, anorexia, weight loss, joint and back pain, and skin ...
Primary aldosteronism (PA), also known as primary hyperaldosteronism, refers to the excess production of the hormone aldosterone from the adrenal glands, resulting in low renin levels and high blood pressure. [1] This abnormality is a paraneoplastic syndrome (i.e. caused by hyperplasia or tumors).
Prolonged stress levels can lead to decreased levels of cortisol in the morning and increased levels in the afternoon, leading to greater daily output of cortisol which in the long term increases blood sugar levels. In the nervous system, structural and functional abnormalities are a result of chronic prolonged stress.
