How can the pituitary gland function when parts of it breakdown?

How can  the pituitary gland function when parts of it breakdown?

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

What is the function of the pituitary gland and how does it relate to acromegaly?

What is the function of the pituitary gland and how does it relate to acromegaly?

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

What is the actual role of the appendix? Does it has immune functions and do people who had it removed have immune problems?

What is the actual role of the appendix? Does it has immune functions and do people who had it removed have immune problems?

Does not matter: Indications for an appendectomy is not an elective option. When you have appendicitis ave to remove it surgically; otherwise it can rupture, cause peritonitis, sepsis, shock and death. It's considered a vestigial structure by most (had a purpose before we became omnivores). Do not worry about the immune function of your appendix. Just remove it. Your body knows what to do afterwards. ...Read more

Can you tell me if it's there. Does he mean the removal of just the tumor itself or the whole pituitary gland?

Please rephrase: Hi. Your question doesn't really make sense. Don't assume we know what you've been diagnosed with. As a pituitary doc (diagnostician, not surgeon), I can tell you we aim only to remove tumors, when indicated, not the whole pituitary gland. Normal human physiology requires pituitary function, and if the whole thing comes out, we need to treat numerous deficiencies. Good luck. ...Read more

I have no movement on the left part of the body due to brain stroke. Is it possible to cure it by stem cell therapy?

Not at this time: There have been some research trials in stem cell therapy for paralysis from stroke but unfortunately no breakthroughs to my knowledge. The university of pittsburgh medical school has been out in front with this type of research. Hopefully someday there will be a treatment that can reverse paralysis. ...Read more

I don't understand why the thymus is inlucded in the lymphatic system, other than the function of t cell maturation, it doesn't make sense?

I don't understand why the thymus is inlucded in the lymphatic system, other than the function of t cell maturation, it doesn't make sense?

Immune system: Thymus functions chiefly to develop t-lymphocytes.Once mature, cells leave thymus and are transported via blood vessels to the lymph nodes and spleen.T-lymphocytes are responsible for cell mediated immunity, activation of certain immune cells to fight infection. Congenital absence of thymus results in patient getting serious infections.Thymus gradually involutes when immune system functioning. ...Read more

What does it mean if a patient has a pituitary tumor that secretes large amounts of tsh?

What does it mean if a patient has a pituitary tumor that secretes large amounts of tsh?

Tumor forming TSH: TSH-secreting pituitary adenomas are benign tumors of the pituitary gland. They produce too much thyroid stimulating hormone (TSH) which causes the thyroid gland to enlarge and produce thyroid hormone in excess, leading to an overactive thyroid (hyperthyroidism) .most common initial therapy for patients with a TSH-secreting pituitary adenoma is transphenoidal resection of the tumour. ...Read more

What is the function of the penil gland in my brain? I have cist on that gland and i need to know could it effect my sexual funtioning?

What is the function of the penil gland in my brain? I have cist on that gland and i need to know could it effect my sexual funtioning?

I : I suspect you mean pineal gland. This is a small gland near the center of the brain. It is known to be involved in the making of melatonin, a chemical that is involved in the sleep-wake cycle. In animals there is some connection with sexuality in that changing melatonin levels and the changing length of days in the spring affect the mating season. In humans there are some connections with the endocrine system, but I am not aware of any direct connection to sexual functioning. Your doctor may recommend a workup by an endocrinologist to check for pituitary gland dysfunction. The pituitary affects thyroid function, hormone production and regulation of water in the body. I hope this answers your question. ...Read more

How could the adrenal gland release neurotransmitters when it isn't part of the nervous system?

How could the adrenal gland release neurotransmitters when it isn't part of the nervous system?

Wrong: Hi. The adrenal gland has two district functional components: the cortex which makes steroid hormones and the medulla which secretes the "neurotransmitters" (but hormones in this context) epinephrine, norepinephrine, and dopamine. The adrenal medulla IS part of the nervous system, and is the equivalent of a presynaptic neuron; release is to blood instead of a postsynaptic nerve or muscle cell. ...Read more

I know masturbation is normal. When done frequently does it affect the internal parts of the reproductive system?

No: Do not worry that your reproductive system is being significantly affected. The only thing might be around frequency. Depending on what you mean, one's sperm count can be less if masturbating to ejaculation several times a day, or even daily.The other thing i would normally explore is what specific things you were worried about.Relationship issues may also be important to address. ...Read more

What is function of gallbladder in body... What will be its impact on body when we removed it for stone surgery.?

Bile storage: The gallbladder stores bile produced in the liver. When you eat a meal, it contracts and releases bile into the first part of the small intestine. The bile helps you break up and digest fat. If the gallbladder is removed, there is a constant trickle of bile into the small intestine. Most people do fine without their gallbladder, and if it is removed for real disease, they feel better. ...Read more

What does it mean to have a peripheral conversion problem with the thyroid hormones?

What does it mean to have a peripheral conversion problem with the thyroid hormones?

Low thyroid: There are 2 main thyroid hormones T4 (4 iodine molecules) & T3 (liothyronine) (3 iodine). T4 is not the active thyroid hormone & gets broken down to the active hormone free T3 (liothyronine) in the periphery or in the cells when needed. If we don't have right nutrients, we don't convert ft4 to ft3 instead it becomes reverse T3 (liothyronine) which blocks ft3 causing symptoms of low thyroid. ...Read more
