Lesions1
- The mechanisms involve lesions in the hypothalamic-pituitary axis and inflammatory changes in the central nervous system (CNS). (allaboutheaven.org)
Anatomy1
- In vertebrate anatomy, the pituitary gland, or hypophysis, is an endocrine gland, about the size of a pea and weighing 0.5 grams (0.018 oz) in humans. (tch-printing.com)
Metabolism6
- The anterior pituitary gland contributes to growth, metabolism, and sexual development. (wikipedia.org)
- This gland secretes hormones that control a wide range of processes including growth, metabolism, blood pressure, and reproductive health. (musclegrowthexpert.com)
- The pituitary gland is also responsible for producing hormones that regulate a wide range of processes, including growth, metabolism, blood pressure, and reproductive health. (musclegrowthexpert.com)
- The hormones produced by the pituitary gland also play a critical role in regulating growth, metabolism, blood pressure, and reproductive health. (musclegrowthexpert.com)
- The pituitary gland is a central regulator of critical physiological processes such as metabolism, reproduction, growth and the stress response. (kcl.ac.uk)
- It stimulates your adrenal glands to produce cortisol (the "stress hormone"), which has many functions, including regulating metabolism, maintaining blood pressure, regulating blood glucose (blood sugar) levels and reducing inflammation, among others. (tomsk.ru)
Disorders1
- This may result from disorders involving the pituitary gland, hypothalamus, or surrounding structures. (medscape.com)
Adrenocorticotropic1
- Adrenocorticotropic hormone: causes the adrenal glands to make cortisol. (mayfieldclinic.com)
Partial2
- however, only 1 or more pituitary hormones are often involved, resulting in isolated or partial hypopituitarism. (medscape.com)
- According to Sheehan in 1939 approximately 41% of survivors of severe postpartum haemorrhage (PPH) and/or hypovolemic shock experienced severe or partial hypopituitarism. (capsulehealth.one)
Hypothalamus and pituitary1
- First some background: Most of the major hormones found in the body are regulated by and released from what is known as the hypothalamic-pituitary axis, involving two distinct but connected areas of the brain, the hypothalamus and pituitary gland. (medicalmarijuana411.com)
Corticotropin2
- Insulin administration shows low levels of corticotropin, indicating pituitary or hypothalamic failure. (doctorlib.info)
- This hormone helps to stimulate the adrenal gland to produce cortisol (also known as corticotropin). (doralhw.org)
Endocrine glands2
- This gland acts as a control center, secreting hormones that stimulate the release of hormones from other endocrine glands. (musclegrowthexpert.com)
- Endocrine glands release hormones directly into your bloodstream. (tomsk.ru)
Secondary3
- Hypopituitarism may be congen-ital or acquired, secondary to pituitary disease or to hypothalamic pathol-ogy that interferes with pituitary function. (brainkart.com)
- Undoubtedly Goliath's great size was due to ** **acromegaly ** **secondary to a pituitary macroadenoma. (serdarbalci.com)
- This panel is useful in determining the health of the hypothalamic-pituitary-testicular axis (HPTA) and whether a man has primary or secondary hypogonadism. (discountedlabs.com)
Hormones produced4
- We will also look at the different hormones produced by the pituitary gland and their impact on overall health. (musclegrowthexpert.com)
- The anterior pituitary is primarily regulated by neuropeptide-releasing and release-inhibiting hormones produced in the hypothalamus. (medscape.com)
- A negative feedback loop occurs such that the hormones produced in the target glands feed back to inhibit the release of their respective regulatory pituitary and hypothalamic factors. (medscape.com)
- The other half of the pituitary gland, the posterior pituitary is responsible for the release of other hormones produced in the hypothalamus, oxytocin and vasopressin. (medicalmarijuana411.com)
Stimulate the pituitary1
- Medicines that stimulate the pituitary during the test may cause side effects. (medlineplus.gov)
Empty sella3
- With a primary empty sella, pituitary function is usually intact. (pediagenosis.com)
- After one year, MRI shows atrophy of the pituitary and a partially empty sella. (tomwademd.net)
- Pituitary function in patients with empty sella syndrome is frequently normal. (msdmanuals.com)
Cells of the anterior pitui1
- The two hormones are produced by the gonadotropic cells of the anterior pituitary gland. (discountedlabs.com)
Sagittal section1
- Pituitary gland, sagittal section. (medscape.com)
Forms of hypopituitarism1
- Additionally, because it was shown that cannabinoids have modulatory effects in the pituitary, it may be possible to treat certain forms of hypopituitarism using cannabis. (medicalmarijuana411.com)
Diagnosis3
- Diagnosis and Treatment of Hypopituitarism. (medscape.com)
- The aims of the present study were: (i) to assess the prevalence of pituitary hormone deficits at diagnosis in a large series of patients undergoing surgery for a NFPMA, (ii) to evaluate post-operative evolution of pituitary functions, and (iii) to identify factors predicting hormonal recovery after primary surgical treatment. (researchsquare.com)
- The diagnosis of hypopituitarism is made by blood tests, but often specific scans and other investigations are needed to find the underlying cause. (allaboutheaven.org)
Antidiuretic2
- The posterior pituitary produces vasopressin (antidiuretic hormone [ADH]) and oxytocin. (medscape.com)
- Less commonly, the posterior pituitary gland's hormones can be affected: vasopressin (AVP) (antidiuretic hormone [ADH]) and oxytocin ( 1 )[ A ]. (unboundmedicine.com)
Hyperprolactinemia1
- We report the three-dimensional CT and MR imaging findings of a case of large craniopharyngeal (transsphenoidal) canal associated with nasopharyngeal extension of a normally functioning pituitary gland, hyperprolactinemia, and hypothalamic hamartoma. (ajronline.org)
Syndrome1
- This started the initial distinction of Sheehan's syndrome from Simmonds' disease (also known as hypopituitarism). (capsulehealth.one)
Insufficiency1
- Question: I have permanent pituitary insufficiency and find that I don't deal with stress well at all. (csrf.net)
Loss of pituitary2
- I now take 3 drugs due to the loss of pituitary hormones. (csrf.net)
- It is far more common than the selective loss of pituitary function. (tomwademd.net)
Known as hypopituitarism1
- If hormone-producing cells are depleted or impaired, levels of hormone can become insufficient, a condition known as hypopituitarism. (kcl.ac.uk)
Patients with hypopituitarism2
- Patients with hypopituitarism are maintained on hormone replacement therapies for life, unless the causative disorder is reversed by treatment or by natural history. (medscape.com)
- All patients with hypopituitarism should carry some identification. (medscape.com)
