What causes a pituitary tumor with a very high prolactin to increase in size and prolactin to go decrease way below normal after taking bromocriptine for 18 months?

Bromocriptine acts on the dopamine receptors to increase dopamine levels which increased dopamine reduces prolactin levels. I would hypothesize that even though your prolactin levels decrease that it would be possible that the tumor could still grow because of the fact that it is abnormal cells and the growth may be irrelevant to your prolactin level. Most pituitary tumors are benign, but not all. I would recommend looking into some diets designed to eliminate cancer. Eat more fruits and veggies that are high in antioxidants, and eliminate oxidants that you have control of.

How surgical hypothyroidism would likely affect prolactin levels?
Thyroid hormones levels decrease, TRH levels increase, and PRL levels increase.
When does an increase in the hormone prolactin occur?
After childbirth
Why does renal failure lead to hyperprolactinemia?
Renal failure and cirrhosis cause delayed clearance of prolactin as it is metabolized by both the kidney and liver the serum prolactin concentration is high in patients who have chronic renal failure and returns to normal after renal transplantation . The major mechanism is a three-fold increase in prolactin secretion, and there is a one-third decrease in metabolic clearance rate
Why would a woman breast leak milk that have never been pregant?
Perhaps there are many possible factors such as:1. GROWTH HORMONES (GH) or somatotrophin and chicken prolactin/ovine prolactin administered by the poultry manufacturing industry in chickens, subsequently affects the pituitary gland to produce breast milk hormones (the fact that I've changed my diet from an Organic Raw Vegetarian to Semi Vegetarian which includes fish and poultry of non organic producers) which increase breast size in humans this would be chicken prolactin which increases the size of chickens and 'fattens' the chickens; (check out: http://www.freepatentsonline.com/5053391.html)2. GLAND STIMULATION from SUCKING THE BREASTSduring love making. The blood flow stimulates the glands of the breasts.;3. ENLARGED PITUITARY CONDITION -- The pituitary gland in addition to producing other hormones for glands like the adrenals (ACTH), growth hormones (GH), thryoid (TSH), follicles for hair (FSH), to name a few, also produces the prolactin hormone (PRL) for breast milk growth. An imbalance can cause a tumor in the Pituitary Gland called hyperprolactinaemia.4. MEDICATIONS such as metoclopramide or thioridazine cause increased levels of the prolactin hormone;5. DUCT ECTASIA in older women can increase milk secretion in the breasts.
As thyroxine levels increase in the blood they exert negative feedback on the release of TSH by the pituitary gland. What effect will this have on the release of TSH?
As thyroxine levels increase the amount of TSH produced will decrease. On the other hand, when TSH levels increase the thyroxine levels will decrease. This is what causes the TSH/thyroxine levels to fluctuate.
What happens within the endocrine system when a person is cut in the arm?
When a person suffers an injury, prolactin and dopamine levels increase. Meanwhile, insulin, thyroid hormones, FSH, LH, estrogen, and testosterone decrease.
What allows Follicle-stimulating hormone and Luteinizing hormone levels to increase again?
Once GnRH levels increase, FSH and LH levels will increase. During pregnancy, GnRH is not required which is responsible for the lack or absence of FSH and LH production. Prolactin can also decrease GnRH production which again will decrease FSH and LH. Luteinizing hormone (LH) levels can also be affected by another hormone called melatonin, which is regulated by the hypothalamus and released by the pineal gland in repsonse to the amount of broad-spectrum light that enters the eyes.
What part of the body does the growth hormone effect?
Everything. In children it can cause dwarfism (which causes more chronic problems) if it is not being produced by the pituitary gland. In adults it can lead to fatigue, increase fat production, decrease in muscle tissue, and thinning of bones. Decrease amounts of hormone from the pituitary gland also causes problems with other endocrine glands.
Does heat increase or decrease thermal energy?
increase
Does x increase or decrease making the y increase or decrease?
no. :)
Which gland starts the process of puberty?
Puberty is started by a sudden increase in hormones, released by the Pituitary gland.
How can you increase your dachshund milk supply?
