6 All-Natural Ways to Keep Your Pituitary Gland Healthy Despite being the size of a pea, the pituitary gland’s role can’t be understated. It’s also known as the master gland due to its pivotal role in regulating your testosterone levels. If a hormonal imbalance occurs, then the problem of origin can likely be traced back to this little feller. 6 All-Natural Ways to Keep Your Pituitary Gland Healthy Despite being the size of a pea, the pituitary gland’s role can’t be understated. It’s also known as the master gland due to its pivotal role in regulating your testosterone levels. If a hormonal imbalance occurs, then the problem of origin can likely be traced back to this little feller. Without diving into all the scientific mumbo jumbo, all you need to know is that the pituitary gland is the main control center that regulates various bodily functions, such as body temperature, heartbeat, sleep, hunger, and thirst. As mentioned, it’s also the central command station that sends signals to your testicles letting it know when and how much testosterone to produce. The pituitary gland is divided into four parts: the anterior lobe, posterior lobe, the intermediate part that lies between the anterior and posterior lobe, and the pituitary stalk. The anterior lobe, though, is the part mainly responsible for growth hormone regulation. This is the region responsible for the production of luteinizing hormones (LH). LH is the “messenger” hormone letting the leydig cells in the testes know ...

Elster's rule provides a guide to the expected approximate 1. The rule follows an even-numbered pattern of 6, 8, 10, and 12. The height of pituitary gland is taken in sagittal MR 1: • 6 mm pituitary gland height in infants and children • 8 mm pituitary gland height in men and postmenopausal women • 10 mm pituitary gland height in women of childbearing age • 12 mm pituitary gland height in women in late pregnancy or in postpartum women Some studies of pituitary height on MRIs in various healthy populations have had various results not necessarily in agreement with this rule 2,3. • 1.

Overview Galactorrhea (guh-lack-toe-REE-uh) is a milky nipple discharge unrelated to the normal milk production of breast-feeding. Galactorrhea itself isn't a disease, but it could be a sign of an underlying problem. It usually occurs in women, even those who have never had children or after menopause. But galactorrhea can happen in men and even in infants. Excessive breast stimulation, medication side effects or disorders of the pituitary gland all may contribute to galactorrhea. Often, galactorrhea results from increased levels of prolactin, the hormone that stimulates milk production. Sometimes, the cause of galactorrhea can't be determined. The condition may resolve on its own. Symptoms Signs and symptoms associated with galactorrhea include: • Persistent or intermittent milky nipple discharge • Nipple discharge involving multiple milk ducts • Spontaneously leaked or manually expressed nipple discharge • One or both breasts affected • Absent or irregular menstrual periods • Headaches or vision problems When to see a doctor If you have a persistent, spontaneous milky nipple discharge from one or both of your breasts and you're not pregnant or breast-feeding, make an appointment to see your doctor. If breast stimulation — such as excessive nipple manipulation during sexual activity — triggers nipple discharge from multiple ducts, you have little cause for worry. The discharge probably doesn't signal anything abnormal, and this discharge often resolves on its own. If you ...

The pituitary gland is a small endocrine organ located within the sella turcica. Various pathologic conditions affect the pituitary gland and produce endocrinologic and neurologic abnormalities. The most common lesion of the pituitary gland is the adenoma, a benign neoplasm. Dedicated MR imaging of the pituitary is radiologic study of choice for evaluating pituitary gland and central skull region. Computed tomography is complimentary and allows for identification of calcification and adjacent abnormalities of the osseous skull base. This review emphasizes basic anatomy, current imaging techniques, and highlights the spectrum of pathologic conditions that affect the pituitary gland and sellar region. Key points • • MR imaging is the study of choice for evaluating primary tumors and other lesions of the pituitary gland and the central skull base region. • • CT is complimentary in evaluating pituitary and other sellar masses given its ability to detect calcification and assess osseous involvement of skull base. • • The adenoma is the most common lesion of the pituitary gland and can be symptomatic because of its endocrine effects or localized mass effect. • • Macroadenomas can have a variety of imaging appearances based on size, cystic/necrotic change, extent of local invasion, and post-treatment effects. • • There is a broad spectrum of disorders that should be considered in the radiologic evaluation of pituitary, sellar, and suprasellar masses. Introduction The pituitary gl...

The pituitary gland is a part of your endocrine system. Its main function is to secrete hormones into your bloodstream. These hormones can affect other organs and glands, especially your: • thyroid • reproductive organs • The pituitary gland is sometimes called the master gland because it’s involved in so many processes. The pituitary gland is small and oval-shaped. It’s located behind your nose, near the underside of your brain. It’s attached to the The hypothalamus is a small area of your brain. It’s very important in controlling the balance of your bodily functions. It controls the release of hormones from the pituitary gland. The pituitary gland can be divided into two different parts: the anterior and posterior lobes. Anterior lobe The anterior lobe of your pituitary gland is made up of several different types of cells that produce and release different types of hormones, including: • Growth hormone. • Thyroid-stimulating hormone. • Adrenocorticotropic hormone. • Follicle-stimulating hormone. • Luteinizing hormone. • Prolactin. • Endorphins. • Enkephalins. Enkephalins are closely related to endorphins and have similar pain-relieving effects. • Beta-melanocyte-stimulating hormone. This hormone helps to stimulate increased pigmentation of your skin in response to exposure to ultraviolet radiation. Posterior lobe The posterior lobe of the pituitary gland also secretes hormones. These hormones are usually produced in your hypothalamus and stored in the posterior lobe unti...

Your endocrine system controls all of your hormones. It’s made up of many different glands, including the pituitary gland. The pituitary gland (including the anterior pituitary) plays a significant role in making sure your hormones function as they should. What Is the Anterior Pituitary? The anterior pituitary is part of the pituitary gland. The pituitary gland is located in your brain and is part of your endocrine system. Your endocrine system is a network of organs and glands within the body that produce and control hormones. Hormones are chemicals that your body makes to regulate and coordinate your body’s functions, telling it what to do and when. The pituitary gland is an important part of the endocrine system. It communicates with many different parts of the endocrine system. Aside from the pituitary gland, the endocrine system contains the following glands and organs: • Adrenal glands. The adrenal glands are small, triangle-shaped glands that sit above your kidneys. They affect your blood pressure, metabolism, sexual development, and stress response. • Hypothalamus. Like the pituitary gland, the hypothalamus is located in the brain. It sends messages to control many of your body’s processes like hunger, mood, thirst, sleep, and sexual function. • Ovaries. Ovaries are typically found in those assigned female at birth. There are typically two ovaries within the body. They produce estrogen, progesterone, and testosterone, as well as eggs. • Pancreas. The pancreas produ...
