What hormones from the hypothalamus, pituitary gland, and possibly thyroid cause calcitonin to be released?
Secretes melatonin: The pineal gland is known for its production of melatonin, a hormone that is naturally released at nighttime and causes us to become tired and eventually go to sleep. In this regard, the pineal gland, through melatonin secretion, regulates sleep onset. This in turn can affect the sleep-wake cycle's homeostasis.

What does Vyvanse (lisdexamfetamine) do for pituitary gland tumors? Can it negatively affect a benign pituitary gland tumor?
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 moreSee 1 more doctor answer
Why adrenal gland?: Unless you have cushing's syndrome, which is a rare abnormality in which the adrenal glands are producing too much cortisone, there is no treatment for the adrenal glands that will cause weight loss. Why do you think you have an adrenal gland problem? ...Read moreSee 1 more doctor answer
Glands grow: If not all of the thyroid was removed, the remnant will likely grow back, especially if the TSH was slightly high or normal (tsh is a stimulus to growth). Surgery usually does not remove every last cell of the thyroid, even if it is called a "total thyroidectomy". See your endocrinologist. ...Read more
No: An adrenal adenoma is a benign tumor of the adrenal gland. It typically causes no complications. Someimes these tumors become "active" or "functioning" producing hormones, often in excess of what the adrenal glands typically produce. This excess of hormones can cause primary aldosteronism, Cushing's syndrome and other medical conditions. They do not stop hormone production.once functional. ...Read moreSee 1 more doctor answer
Generally not: Isolated pituitary tumors generally are not genetic. These are the majority of the pituitary tumors and include prolactin, growth hormone, and non-secreting pituitary tumors. There are associations with other tumors: the multiple endocrine neoplasia syndrome-1 (mens-1) that are believed to be genetic linked. This is inherited in an autosomal dominant fashion. ...Read more
Adrenal or pituitary: What is the cause of your addison's? If the adrenals have failed, then the pituitary may be working fine, but the pituitary acth cannot stimulate a dead adrenal. If the pituitary is the cause of the addison's, then other hormones may also be affected. Best to discuss with your endocrinologist. ...Read more
Pituitary hormones: It is possible that some pituitary hormones do not work, and others do work. For example, after a pituitary insult (tumor, trauma, etc), you could lose the gonadotropins (fsh, lh), but still have preserved acth and TSH (adrenal and thyroid). Some of this is related to the pituitary anatomy, and the locations of certain populations of cells. ...Read more
With medication.: The adrenal glands produce androgenic hormones that can be blocked with medication. Aminoglutethimide, ketoconazole, abiraterone & tak-700 (orteronel) are examples, blocking the synthesis of steroid compounds in the glands. Other essential hormones that are blocked may need to be replaced. Surgical removal of both glands would also eliminate adrenal androgens, but it is not done for this purpose. ...Read more
Hormone replacement: Yes, but you will need to be on hormone replacement. The two most critical hormones are cortisol (adrenal) and thyroid. Testosterone or estrogen may need replacement. If the posterior pituitary is removed, DDAVP (desmopressin) will need to be given to regulate water balance. Discuss with an endocrinologist. ...Read more
Pituitary "enlarged": You need a ct or MRI to see the pituitary. The pituitary normally enlarges during pregnancy and puberty. Hypothyroidism (high tsh) can make it enlarged. Bad stuff: tumors in the pituitary can develop, and they sometime secrete excess hormones, giving rise to many different disorders. Aneurisms, cysts, other things can happen, but all these are readily seen on mri. ...Read more
Yes with treatment: Yes, with replacement hormones. Such treatment is inconvenient at best and not always completely successful. But sometimes necessary if it isn't possible to save the pituitary, e.g. after certain surgeries, e.g. removal of a tumor in the area. ...Read moreSee 2 more doctor answers
Pituitary Dis: Pituitary gland has two parts, the adenohypophysis produces hormones like fsh, lh, human growth, igf-1, prolactin, and prolactin releasing dactors, acth, beta-endorphine, tsh, melanocyte stimulating hormone. On the posterior part or neuro-hypophysis: vasopresin or anti-diuretic hormone, oxitocine. Most. Common conditions are bening tumors producing excessive hormone(prolactinomas) or lack of hormo. ...Read moreSee 2 more doctor answers
