Doctor insights on:
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 moreSee 1 more doctor answer

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
Light / dark: The brain takes in light in decreasing and increasing amounts depending on time of day and time of year, and a center in the brain, the suprachiasmatic nucleus, placed over the optic nerves, takes the information, and sets the "internal clock". This nucleus tells the pineal gland when to secrete melatonin, the hormone that tells us when we're supposed to get sleepy. ...Read more

Anti-enuretic: Anti-diuretic hormone, or vasopressin, is produced in much greater levels at night and when we are lying down flat, thus making the urine produced at night more concentrated & allowing most of us to sleep uninterrupted during the night. It is marketed as a medicine under the name ddavp (desmopressin). When used properly, it is a very effective treatment for bedwetting. ...Read more
Yes: Natural circadian rhythm is known to be 25 hours. The "clock" is in the part of the brain which computes our ability to adapt to the mental and physical stresses imposed by environment. We compress the 25 hour to a 24 hour rhythm, thus adapting to our world. The 24 hour rhythm obeys the dark/light cycle and is indeed controlled by the computer in the brain. ...Read more
Maybe: Vit d has so many affects in the body that disrupted circadian rhythm could be a possibility. It is not one of the symptoms we look for to diagnose vitamin d deficiency. Best way to find out for you is to take vit d and if your circadian rhythm improves with just that then yes it affected you. ...Read more
FSH,LH: Gnrh stimulates follicle stimulating hormone & luteinizing hormone which stimulates the ovary to produce estrogen and Progesterone which stimulates ovulation which causes increased Progesterone which causes secretory endometrium which prepares the endometrium to allow implantation of a fertilized egg. If no fertilized egg, Progesterone falls which stimulates gnrh to again rise & the cycle repeats. ...Read more
Good question: Gnrh would seem by its name to help release gonadotropin. And if used in a certain fashion it could cause the release of gonadotropins (lh, fsh). However when given in a shot and having a sustained effect on the pituitary, it actually suppresses the release of lh and fsh. And this aspect of the medication can be used to help in many situations. ...Read more
