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 a pituitary tumor cause delayed cortisol response on acth stim test?

Could a pituitary tumor cause delayed cortisol response on acth stim test?

Definitely: If the tumor has destroyed the pituitary's ability to respond appropriately to hypothalamic cortisol releasing hormone, it can even lead to secondary adrenocortical insufficiency. Check w/your doctor. ...Read more

Will repeated adrenal crisis weaken the adrenal gland?

Will repeated adrenal crisis weaken the adrenal gland?

No: People have an "adrenal crisis" only when the adrenal is already very weakened or absent. The crisis can be dangerous, but will not affect the gland itself. ...Read more

How does oral cortisol affect acth hormone and aldosterone levels?

How does oral cortisol affect acth hormone and aldosterone levels?

Poor correlation: Hi. Oral cortisol (aka hydrocortisone) does not reliably affect ACTH secretion nor aldosterone levels. That is somewhat unfortunate for those of us treated adrenal insufficiency, since determination of proper dose is based solely on clinical response, and not labs. Aldosterone is driven by the renin-angiotensin system bypassing the pituitary. UIHC is excellent, so you have great docs close at hand ...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

What pituitary hormones cause the adrenal gland to produce mineralocorticoids, glucocorticoids, and androgens and estrogens including pregnenolone?

What pituitary hormones cause the adrenal gland to produce mineralocorticoids, glucocorticoids, and androgens and estrogens including pregnenolone?

Pituitary & steroids: Hi. Pituitary ACTH regulates adrenal cortisol production; it also acutely stimulates aldosterone, but is not the principle regulator. LH principally stimulates gonadal steroid hormone production (both genders make androgens & estrogens, but in opposite dominance). Pregnenolone is early in the steroidogenic pathway in both adrenals and gonads. Good luck! ...Read more

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

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

Could adrenal glandulars increase dhea and testosterone levels?

Could adrenal glandulars increase dhea and testosterone levels?

Yes: Glandulars have been a traditional source of these hormones, but there absorption is not realiable. Check with your doctor or check out acam which is an organization that has investigated and held standards on hormone supplementation. They even have a physician referral on there website. ...Read more

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

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

Are hormones produced by thyroid gland tropic hormones?

Are hormones produced by thyroid gland tropic hormones?

Hormones: A tropic hormone is a hormone secreted by one gland and then stimulates another gland; for example, the pituitary makes TSH, which targets the thyroid and causes the thyroid to make T4 and T3 (liothyronine). The thyroid hormones (T4, T3 (liothyronine)) target other organs (heart, CNS, GI, etc), but not really other glands, so are not really tropic hormones. ...Read more

Does resetting the hypothalamus affect pituitary tumor?

Does resetting the hypothalamus affect pituitary tumor?

Depends on case: If you mean suppressing the gland, such as using bromocryptine for a pituitary adenoma, it can help control the symtpoms and prolactinomas can shrink. For other tumors, this may not be the case art all - for metastases to the pituitary or for craniopharyngioma, addressing hormone function generally does not affect the tumor's growth, although hormone symptoms can be relieved quite a bit. ...Read more
