Hyposecretion Of Cortisol
Many symptoms: Parathyroid hormone is responsible for regulating calcium level in blood. The most common cause of hyperparathyroidism is a growth on your parathyroid gland causing overproduction of this hormone. If high, it will raise calcium level in your blood causing osteoporosis, kidney stones, kidney problems, bone pain, constipation, abdominal pain, psychological problems... ...Read moreSee 1 more doctor answer
Stones bones groans: Main symptoms are related to calcium in the urine (kidney stones), abnormal bone metabolism which may lead to pain, osteoporosis, or even fractures, memory disturbances or mood swings. There are data suggesting that untreated hyperparathyroidism may be linked to excess cardiac mortality. ...Read moreSee 1 more doctor answer
43 yo f, afternoon cortisol high, cortisol suppression test high, CT of adrenal glands normal. Other causes of elevated cortisol?
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 moreSee 1 more doctor answer
Vasopressin,: also known as antidiuretic hormone/ADH, is a "pituitary" hormone which acts to retain water and constrict blood vessels. It increases water reabsorption in the kidney's collecting ducts. Decreased release due to alcohol intoxication or tumor leads to increased blood sodium/excessive urination/thirst. Excess vasopressin leads to low sodium. A number of problems cause inappropriate ADH-tumors, drugs ...Read moreSee 1 more doctor answer
A deficiency in the release of vasopressin (antidiuretic hormone) by the posterior pituitary gland. Why?
Possibly infarction: Possibly a tumor or something else. Lack of blood supply to the pituitary gland or a pituitary tumor may change the secretions of adh (vasopressin). However, there are other causes also, such as pregnancy that can cause this area to be infarcted (loss of blood supply). ...Read moreSee 1 more doctor answer
Acth stim test. Results of rise of cortisol and 17-0hp normal. What causes moderate elevation of androstenedione, slight elevation testosterone?
Production of antidiuretic (adh), thyroxine and t3, (liothyronine) parathyroid (pth), hormones of the adrenal cortex and the pancreas, can you tell me about this?
Complex: Please ask a specific question. This is way too complex and vague to answer. If you want to know about all these hormones, consider an Endocrinology fellowship at a major teaching hospital. Of course, before that, you will need a BS, an MD, and a 3 yr Internal Medicine residency. ...Read more
Normal: Hi. Yes, that's the normal endocrine feedback loop to prevent the pituitary from secreting too much ACTH. What do you mean, "what to do"? I believe you WANT normal function. You haven't indicated any problem. Here's to your healthy, normal hypothalamic-pituitary-adrenal axis! ...Read more

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
What hormone inhibits the secretion of adh (vasopressin)? And what situations override the release of this inhibiting hormone?
ADH (vasopressin) secretion: ADH (vasopressin) is mostly controlled by plasma osmolality and plasma volume. Diabetes insipidus occurs when ADH (vasopressin) is not secreted (head trauma, pituitary tumor) or when the kidney does not respond to it (nephrogenic di). Ethanol inhibits adh, (vasopressin) as does atrial naturetic protein, but these are lesser influences than osmolality and volume. ...Read more
Puberty & fertility: Regulates pubertal development & overall growth plus essential for fertility & sperm production.Fsh "matures" sperm producing cells in the testes. These cells, called spermatogonia, are stimulated to undergo meiotic division.This causes the full complement of 23 pairs chromosomes to split into 23 single chromosomes for the sperm nucleus.One of which is either an x or a y which determine fetal sex. ...Read more
