Tumors that grow from the pituitary gland can affect the whole body by interfering with normal hormone levels. The pituitary gland is a small, bean-shaped organ that sits at the base of the brain, behind the bridge of the nose (Fig. Thyroid-stimulating hormone: causes the thyroid gland to make other hormones that control growth, temperature, and heart rate. Luteinizing hormone and follicle-stimulating hormone: control the menstrual cycle in women and sperm production in men. Functional tumors secrete abnormal levels of hormones and interfere with the normal hormone regulation process. Symptoms of a pituitary tumor vary depending on its size and hormone secretion function; many are asymptomatic. Non-secreting tumors have few symptoms and are difficult to recognize until they grow quite large.
If you have symptoms that suggest a pituitary tumor, your physician will work with a team of specialists to confirm the diagnosis. First, the doctor will obtain your personal and family medical history and perform a physical examination. Magnetic Resonance Imaging (MRI) scan uses a magnetic field and radiofrequency waves to give a detailed view of the soft tissues of the brain.
Endocrine evaluation measures hormone levels in the blood or urine to detect abnormal levels caused by pituitary tumors. A visual field acuity test is performed by a neuro-ophthalmologist to detect vision loss and missing areas in the field of view. Treatment options vary, depending on the type, grade, size, and location of the tumor, and your age and general health.
The production of growth hormone can be controlled with the drugs octreotide (Sandostatin) or pegvisomant (Somavert), which are used in conjunction with surgical removal. To control the production of ACTH, drugs such as mitotane (Lysodren), ketoconazole (Nizoral), and aminoglutethimide (Cytadren) may be prescribed.
Surgical removal of a pituitary tumor may be performed as a minimally invasive endoscopic transsphenoidal, traditional transsphenoidal, or a craniotomy approach. External beam radiation is delivered from outside the body by a machine that aims high-energy rays (x-rays, gamma rays) at the tumor.

You squat, you bench, you curl your way to a better body each and every day you set foot in the gym. This guide will lay the foundation for a solid supplement program; one that is detailed and tactfully assembled for maximum benefit. Protein powders in general are great for when you have no time to fix a meal or need extra protein without downing another chicken breast or steak. 20 grams upon waking in the morning: Your body has fasted for up to eight hours or more, so it is imperative that you down a shake first thing when you wake up. 20 grams pre-workout: It is time to get the levels of aminos in the bloodstream up once again.
40 grams post-workout: This is prime time to get a quickly digested protein in the body along with about twice the simple carbs (80 grams).
3-5 grams pre-workout: Taken with a moderate amount of complex carbs and 20 grams of whey protein taking creatine at this time will guarantee your levels are filled up. 3-5 grams post-workout: Within 30 minutes after training combine creatine with 40grams of whey protein and 80 grams of simple carbs to get a potent growth producing shake.
Another convenient protein source, casein protein is slow digesting so it will be digested and released into the bloodstream at a steady rate feeding the muscles over a longer period of time. 20 grams post-workout: Take in 20 grams of casein along with your other post-workout supplements.
20 grams in the middle of the night: Since it is slow digesting, you can also benefit drinking a shake in the middle of your sleep to ensure your body is getting the protein it needs.
7-10 grams upon waking in the morning: This will be taken with your small whey shake mentioned above. 7-10 grams post-workout: Again, taking glutamine after a workout will help with glycogen uptake to quickly start the recovery process and get you in that anabolic state. 7-10 grams 30 to 60 minutes before sleep: This is another great opportunity to protect your hard earned muscle right before you go to bed.
BCAAs leucine, isoleucine and valine are used for fuel during intense workouts thus preventing your body from scavenging hard-earned muscle for energy.
5-10 grams upon waking in the morning: BCAAs first thing in the morning is just another weapon in your arsenal to ward off the catabolic effects of fasting most of the night. 5-10 grams pre-workout: Again, taking BCAAs before a workout can fuel the body with energy so you can spare muscle tissue and it will also keep you in an anabolic state for growth. Readily converted to Nitric Oxide (NO) in the body arginine is a powerful supplements for muscle building with a host of benefits. 2-3 grams upon waking in the morning: At this time arginine will dilate blood vessels to shuttle in the nutrients of other supplements. 2-3 grams pre-workout: This will enhance the natural increase of growth hormone before a workout. 2-3 grams 30-60 minutes before sleep: This is another time to take advantage of the burst of growth hormone as arginine will only enhance this effect. As a proven hormone booster Tribulus Terrestris can increase testosterone from cholesterol in the testicles. ZMA (the combination of zinc magnesium plus vitamin B6) has been shown to increase IGF-1 and testosterone levels. Antioxidants have the ability to rid the body of free radicals which are produced from periods of severe stress such as from an intense workout. 500 mg of vitamin C at your post-workout whole meal: Vitamin C will help with joint health and immune function. 200-400 IU of vitamin E at your post-workout whole meal: Vitamin E has the ability to reduce muscle cell damage and helps with recovery. Two types of glands in the body Exocrine – secrete products through a duct onto epithelial surface, e.g. Autoregulation Down-regulation: Continued presence of a hormone triggers decrease in number of hormone receptors.
Hormone release and target cell response Pulses: some hypothalamic and pituitary hormones are released in sudden bursts and the frequency of these results in different target cell responses.
Acromegaly is a serious condition that is nearly always caused by a tumor of the pituitary gland (an adenoma). The pituitary gland (or in this case, the tumor) releases growth hormone into the blood stream. Large pituitary tumors (macroadenomas) can cause additional symptoms related to compression of the optic nerves or chiasm (crossing point of the optic nerves). If the tumor develops before bone growth is completed (in childhood), overdevelopment of the entire body (gigantism) is the result. In unusual cases (typically pre-menopausal females), the GH levels can be high with a normal IGF-1 can be normal.  This is thought to be an estrogen-resistance type phenomena.

Tumors that have invaded beyond the confines of the sella (the space where the normal pituitary gland sits) have a lower chance of cure surgically. Somatostatin analog (Octreotide, Lanreotide) injections (typically administered monthly) suppress GH production in about 70 percent of patients, cause significant tumor shrinkage in 30 percent to 50 percent of patients, and often improve symptoms of soft tissue swelling, headache, joint pains and sleep apnea.
Other therapies include drugs which block the action of growth hormone at its liver receptor, thereby normalizing IGF-1 levels. For patients whose acromegaly cannot be controlled by surgery or medicines,stereotactic radiosurgery can be effective in some cases. The lowering of GH and IGF-1 levels takes an average of 18 months with stereotactic radiotherapy. Long-term cure of acromegaly after transsphenoidal surgery is seen in approximately 80 percent to 85 percent or patients with smaller tumors (microadenomas) and in approximately 50 percent to 60 percent of patients with larger tumors (macroadenomas). It secretes hormones that control sexual development, promote bone and muscle growth, respond to stress, and fight disease. Cortisol helps control the use of sugar, protein, and fats in the body and helps the body deal with stress. Tumors of the pituitary gland occur in 15% of adults and are classified as functional or nonfunctional. These tumors behave according to their cell of origin and are named for the specific hormone they produce.
Instead, they grow until their size and mass effect cause headache, vision loss, nausea, vomiting, or fatigue. The most common pituitary tumor, a prolactinoma, causes an overproduction of the hormone that helps control sexual function.
Most commonly found in men, these pituitary tumors are larger and may grow toward the third ventricle of the brain.
Some researchers believe they occur when a cell in the pituitary gland becomes abnormal or mutates. This team may include a neurosurgeon, otolaryngologist (ear, nose, and throat surgeon), endocrinologist, ophthalmologist, radiologist, and pathologist. In addition to checking your general health, the doctor performs a neurological exam to check mental status and memory, cranial nerve function (sight, hearing, smell, tongue, and facial movement), muscle strength, coordination, reflexes, and response to pain. This test measures both central vision (how much is seen when looking straight ahead) and peripheral vision (how much is seen in all other directions while staring straight ahead). Medication, surgery, and radiation either alone or in combination, are used to treat pituitary tumors and return hormone levels to normal. This technique is performed through an incision made under the upper lip (sublabial) along with removal of the nasal septum to access the tumor. Craniotomy approach to a pituitary macroadenoma that extends down into the sphenoid sinus and up into the third ventricle. Radiation works by damaging the DNA inside cells making them unable to divide and reproduce. The two main technologies are the Leksell Gamma Knife and linear accelerator systems such as the BrainLab Novalis. A facemask is used to precisely localize the tumor and accurately reposition the patient for each treatment session. Small, slow-growing tumors that produce few symptoms may be observed with routine MRI scans until their growth or symptoms necessitate surgery.

Norberto Andaluz, discusses Management Options for Pituitary Tumors in this webinar produced in conjunction with the Pituitary Network Association. It will be perfectly timed for the greatest results and even spelled out for the beginner to the advanced bodybuilder. Easily digested, portable and effective, whey is a must for anyone seeking gains in lean muscle mass. Whey is a convenient way to feed the muscle and boost gains especially when you need it most. This will shut down the catabolic state you may be in and get you on that road to growth once again.
Taking whey prior to your workout will ensure that your muscles will have a steady stream of protein during your workout so that it can actually begin the rebuilding process early.
No later than 30 minutes after a workout down this cocktail along with a few other ingredients to boost insulin levels which will stimulate protein synthesis by driving glucose and amino acids into the muscle.
As it gets converted into creatine phosphate in the muscles, which produces energy for contractions during training, supplementing with creatine can ensure that levels of it are topped off.
Whey is used to get instant nourishment to the muscles while casein is taken for when the whey is digested and the muscles still need aminos for recovery.
During sleep the body is basically fasting and this may cause your body to dip into a catabolic state. Again, this will be absorbed quickly to help get your body out of a catabolic state it may have slipped into overnight. At other times of day BCAAs help stimulate protein synthesis and ward off cortisol, the catabolic hormone. Your body can readily utilize BCAAs as fuel while whey and glutamine quickly get to muscle tissue.
It allows more blood flow to muscle by dilating vessels to allow more nutrients in such as amino acids and glucose as well as hormones like growth hormone, testosterone and insulinlike growth factor-1 (IGF-1).
It also has the ability to enhance the firing of nerves in muscle for increased strength during workouts. Zinc has very powerful recovery benefits and magnesium will actually calm the nervous system down so the body has an easier time resting. It is wise to supplement with vitamins C and E to combat this damage and keep your body in an anabolic state.
All of your supplements for muscle building questions answered from timing to dosages, now you can get on the road to growth. Concentration: unlike neurotransmitters, more hormone does not necessarily mean a bigger target cell response (thresholds, inverse effects).
Growth hormone acts on special liver cells, causing the release into the blood stream a hormone called Insulin-like Growth Factor (IGF-1). This can cause loss of peripheral vision (bitemporal hemianopsia). Macroadenomas can also compress the normal pituitary gland, causing pituitary insufficiency (loss of pituitary function). This can include enlargement of forehead and jaw with pronounced under bite, spreading teeth and enlarging tongue.
IGF-1 levels vary with age and gender, and therefore it is important to use the correct control values.
The gland has a larger anterior lobe (adenohypophysis) and a smaller posterior lobe (neurohypophysis).
A cross-section of the pituitary gland (green) shows its relationship to the optic chiasm above, the sphenoid sinus below, and the cavernous sinuses on each side. A healthy pituitary gland releases secretions into the bloodstream and provides feedback to the hypothalamus. For example, a prolactin-secreting pituitary tumor (prolactinoma) arises from prolactin-producing cells.
Based on size, pituitary tumors can be either microadenomas (less than 10mm) or macroadenomas (larger than 10mm).
Of hormonally active adenomas, about 50% secrete prolactin, 20% secrete growth hormone, 20% secrete adrenocorticotropic hormone, and 10% secrete multiple hormones.

In women, the tumor can cause menstruation to stop (amenorrhea) or inappropriate production of milk by the breasts (galactorrhea). Hyperthyroidism can accelerate the body's metabolism, causing sudden weight loss, irregular heartbeat, and nervousness or irritability. They can also impair hormone secretion from the pituitary gland, which can cause fatigue, weakness, loss of body hair, and pale skin.Pituitary apoplexy. Multiple endocrine neoplasia type 1 (MEN 1) is a rare condition with simultaneous tumors of the pituitary, pancreas and parathyroid glands. It is important to seek treatment at a center that offers the full range of options including surgery, radiation, and endocrine therapy. Prolactinomas can be controlled with the drugs cabergoline (Dostinex) or bromocriptine (Parlodel), which reduce the size of the tumor while maintaining normal prolactin levels. For growth hormone-producing and ACTH-producing tumors, surgery is the treatment of choice to reverse the endocrine problems.
The endoscopic technique is replacing the traditional microscopic approach as it reduces the trauma to the nasal tissues and the recovery time for the patient.
The goal of radiation therapy is to maximize the dose to abnormal tumor cells and minimize exposure to normal healthy cells. Too much prolactin causes abnormal milk production in the breasts, lack of menstruation, infertility, and decreased sex drive. This information is not intended to replace the medical advice of your health care provider.
You are a disciplined hard worker who accepts nothing less than the best from your workouts and nutrition strategies. Now, you want the protein to get in rather quickly so no complex carbs or fats, just protein, some simple carbs and a few other things (which we will get to in a moment). Plus, creatine will force more water into the muscle cells creating an anabolic environment increasing protein synthesis. The insulin response from the simple carbs will also shuttle that creatine right into the muscle. Ingesting a shake at around three or four hours after going to bed will guarantee your quest for mass is still on track. As one of the most plentiful amino acids in the body, glutamine assists in recovery by helping muscle cells take up glycogen after a workout, boosting growth-hormone levels and maintaining immune function so you can stay healthy. Also, having a greater water delivery into the muscle cells means an increase in protein synthesis, which, in turn, spells more muscle growth. Newer surgical techniques, such as theexpanded, endoscopic endonasal approach have now allowed surgeons to cure some of these tumors. Dopamine agonists (same ones used to treat prolactinomas) are sometimes tried, but effective in only a minority of patients.
The hypothalamus then regulates pituitary hormone levels, depending on the needs of the body. Both of these conditions affect the kidneysa€™ ability to regulate the balance of water and electrolytes.
Large tumors can press on the optic nerves and invade the cavernous sinuses, which house the carotid arteries and the nerves involved in eye movement. In men, prolactinomas may cause enlarged breasts (gynecomastia), erectile dysfunction or impotence, infertility, decrease in body hair, and low sex drive. A neurosurgeon, ENT surgeon, endocrinologist and radiation oncologist work as a team to treat pituitary tumors. Expanded endoscopic transsphenoidal surgery involves opening more bone into the anterior skull base. Because a single radiosurgery dose is more damaging than multiple fractionated doses, the target area must be precisely located and completely immobilized with a head frame or facemask. Benign tumors, whose cells divide slowly, may take several months to a year to show an effect. You and your doctor can weigh the risk of symptoms developing versus the risk of treatment intervention. It can also help delay fatigue during a workout so you can turn up the intensity for a longer period of time. Everyone is different so some supplements may be a better choice for you than others.Just make sure you are eating a bodybuilding friendly whole food diet because without it supplements for muscle building will not save the day. Treatment options aim to remove the tumor or control its growth and restore normal hormone function. Tumor growth may compress the normal pituitary gland, compromising its function and manifesting symptoms of decreased pituitary function.
Other symptoms include excess sweating, high blood pressure, heart disease, diabetes, and arthritis. Cushinga€™s can also cause diabetes, menstrual irregularities, excessive hair growth, bruising, hypertension, and bone fractures from calcium depletion. Symptoms include sudden onset of a severe headache and vision changes, including vision loss, double vision, or drooping of an eyelid.

This enables the surgeon to safely expose very large tumors that extend beyond the boundaries of the transsphenoidal approach. Unfortunately you sometimes find that your gains have slowed or stopped or perhaps even regressed! The digestive system requires so much glutamine to function that it will take it from muscle tissue so supplementing is a no brainer. Eat plenty of complex carbs such as potatoes, wheat pasta, rice, wheat bread, and oatmeal along with lean proteins such as lean beef, turkey, chicken, eggs and fish. The pituitary gland is bordered on either side by the cavernous sinuses and below by the sphenoid sinus. Pituitary apoplexy requires emergency treatment, usually with corticosteroids and often surgery. It provides the surgeon with direct visualization of compressed structures, such as the optic nerves or anterior cerebral arteries.
Next, the neurosurgeon removes the tumor by passing long instruments through the nostril while watching the monitor.
The internal carotid arteries and the nerves that control eye movement lie on the sides of the pituitary.
Craniopharyngiomas typically grow from the pituitary stalk upward into the third ventricle and cause symptoms similar to pituitary adenomas.
Surgery is usually carried out with the aid of computer image guidance (an anatomical navigation system akin to a GPS). The goal is to precisely expose the tumor and to avoid nearby carotid arteries or optic nerves. A small bone flap above the eye (supraorbital craniotomy) is cut and removed to access the brain (Fig. When pituitary tumors grow they can compress the above-mentioned structures and cause symptoms.
A craniotomy is required for large tumors that have invaded nearby tissues and cannot be removed through a transsphenoidal approach.
