Does acth causes both aldosterone and cortisol secretion?

Does acth causes both aldosterone and cortisol secretion?

ACTH ALDO Cortisol: I have seen two families in which ACTH is the major driver for aldo production. They have the syndrome called GRA (Glucocorticoid Remedial Aldosteronism) caused by a cross over mutation in the genes controlling aldo production so that the major controller of aldo is ACTH. As you are young and making this question if you also have HTN your team should consider this. Many do not have low K. ...Read more

What is plasma acth cortisol response?

What is plasma acth cortisol response?

Test adrenal fxn.: This test is to check on whether or not your adrenal glands are working right. The acth action is to increase production and release of corticosteroids. In the test, a small amount of synthetic acth is injected and the amount of cortisol the adrenals produce in response is measured. This is used to check for things like primary and secondary adrenal insufficiency, and addison's disease. ...Read more

Could panic attacks cause excess levels of catecholamines in urine tests?

Could panic attacks cause excess levels of catecholamines in urine tests?

Temporary, maybe: 24 hour urine tests for catecholamines are checking for epinephrine, norepinephrine, & other compounds that can be produced by catecholamine-secreting tumors called pheochromocytomas. Panic attacks alone might temporarily raise these levels, but not in sustained fashion like one of these tumors can. When present, pheochromocytomas can cause anxiety and panic attacks and raise urine catecholamines. ...Read more

Can psychological stress increase cortisol levels?

Can psychological stress increase cortisol levels?

Yes......: The short answer is yes. The longer and still very inadequate answer is yes, but the effect can vary based on the type of stress, the chronicity of the stress, the age, gender, genetics and emotion traits of the individual being stressed and so on. Current theory would hold that the origin of many of the inflammatory conditions we face, including depression, can be found in question you ask! ...Read more

Why does acetylcholine, an inhibitory neurotransmitter, cause the adrenal glands to release stimulatory hormones?

Why does acetylcholine, an inhibitory neurotransmitter, cause the adrenal glands to release stimulatory hormones?

Not correct: Hi. Acetyl choline (ACh) is not an inhibitory neurotransmitter. The sympathetic nervous system uses ACh as the neurotransmitter in the sympathetic ganglia (the 1st synapse outside the CNS). Usually that's from one neuron to another, but in the adrenal medulla, the cells are really the second neuron, but they release their contents (catecholamines) into the blood, not onto an organ (like the heart) ...Read more

Does alcohol make the adrenal glands release adrenaline?

Does alcohol make the adrenal glands release adrenaline?

No: However, alcohol can cause various symptoms that can seem like the adrenal glands are releasing adrenalin. Some people will flush after drinking alcohol, this can occur for genetic reasons (common in asians) or rarely due to a medical disorder (carcinoid, lymphoma). ...Read more

43 yo f, afternoon cortisol high, cortisol suppression test high, CT of adrenal glands normal. Other causes of elevated cortisol?

Pituitary : Cortisol is under control of the pituitary. You need to know if the source is coming from the pituitary. We call this Cushing disease. See a specialist to work this up. Cushing's is one of the most difficult diagnosis to make, even for a specialist. ...Read more

If high cortisol can decrease serotonin levels then can low cortisol(like due to iatrogenic adrenal suppression) increase serotonin levels?

If high cortisol can decrease serotonin levels then can low cortisol(like due to iatrogenic adrenal suppression) increase serotonin levels?

That: Is a tricky one because there is not enough evidence of low cortisol causing low levels of serotonin. Depression, chronic and severe, is associated with low serotonin and could lower cortisol levels. ...Read more
