How To Improve Pituitary Gland Function
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
Yes: Only the portion of the gland experiencing dysfunciton is affected. ...Read more
Growth Hormone: The pituitary makes a number of hormones that control the thyroid, adrenal, milk production, reproduction, etc. One of these hormones is growth hormone (gh). A pituitary tumor can overproduce a hormone, and when gh is too high, it causes acromegaly. There are a number of medications that help lower the gh and treat acromegaly, but surgery is usually required. ...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
Hypothalamus not functioning correctly and the pituitary gland flattened. Many horrible symptoms, any meds that can help to alleviate my symptoms.?
Specialist: You must see a board certified neuro-endocrinologist. ...Read more
Can you explain the regulation of adrenal cortex function by the way of the pituitary gland stimulation of the adrena?
Feedforward/feedback: Hi. Hypothalamus important, but to keep it simple, pituitary ACTH stimulates the adrenal cortex to make cortisol. Cortisol negatively feeds back to suppress pituitary ACTH. If cortisol falls or a big stress is encountered, ACTH goes up and stimulates more cortisol production. The pituitary "sees" the increase in cortisol, and cuts back on ACTH to keep cortisol in appropriate range. Diurnal pattern ...Read more
How do you test the function of a pituitary gland? Can a flattening one cause my weight gain and chronic headaches?
I had and MRI due to amenorrhea and low progesterone, it shows pituitary gland smaller than usual. Does size affect function?
Usually not: The size of the pituitary usually does not relate to the function. Some people have an "empty sella", where you cannot see the pituitary gland at all, but still have normal pituitarty function. ...Read more
Not directly,: But the pituitary gland and the hormones it produces are involved in multiple metabolic pathways important in maintaining the function of various organ systems. For example, a problem with thyroid stimulating hormone (TSH, produced by the pitutary), can lead to hypothyroidism which can, among multiple other symptoms, cause breathing issues. ...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: We care for many patients who have panhypopituitarism. It becomes complicated, but essentially, there are medication available to replace the vital hormones no longer manufactured by an absent pituitary. ...Read more
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 more
