Hypophysitis is a rare disease where the pituitary gland becomes inflamed. The pituitary is a small gland at the base of the brain that makes many hormones that control growth, thyroid, adrenal glands, sex hormones, and water balance. In hypophysitis, Read More …

Nelson’s syndrome is a rare problem that can happen in people who had both adrenal glands removed to treat Cushing’s disease. After the adrenal glands are gone, the small pituitary tumor in the brain that makes ACTH (a stress hormone) Read More …

Syndrome of Inappropriate Antidiuretic Hormone Secretion (SIADH) is a condition where the body makes or releases too much antidiuretic hormone (ADH), also called vasopressin. ADH is a hormone that normally helps the kidneys save the right amount of water and Read More …

Pituitary ACTH hypersecretion means that the pituitary gland makes too much of a hormone called ACTH (adrenocorticotropic hormone). The pituitary is a small gland at the base of the brain. ACTH tells the adrenal glands (on top of the kidneys) Read More …

Hyperprolactinaemia means that the level of a hormone called prolactin in your blood is higher than the normal range for your age and sex. Prolactin is made by the pituitary gland, a small organ at the base of the brain. Read More …

Acromegaly is a long-term (chronic) hormone disorder in adults. It happens when the pituitary gland, a small gland at the base of the brain, makes too much growth hormone (GH) for a long time. The high GH makes the liver Read More …

A hypothalamic hamartoma is a small, non-cancer growth made of normal brain cells that are in the wrong place in the hypothalamus, a deep part of the brain that controls hormones, sleep, temperature, hunger, and many body rhythms. It forms Read More …

Neurogenic diabetes insipidus is a brain-related water-balance disorder. In this condition, the brain does not make or release enough of a hormone called antidiuretic hormone (ADH), also known as arginine vasopressin (AVP). ADH normally helps the kidneys save water and Read More …

Tertiary adrenal insufficiency is a condition where the brain, especially the hypothalamus, does not send enough signals to tell the adrenal glands to make cortisol, an important stress hormone. In this condition, the adrenal glands themselves are usually normal, but Read More …

Adiposogenital dystrophy is a rare hormone disorder where a problem in the brain (mainly the hypothalamus and pituitary region) causes obesity plus low sex hormone levels (hypogonadism). Children or teenagers with this condition usually gain a lot of weight, grow Read More …

Insulitis means inflammation inside the tiny insulin-making parts of the pancreas, called the islets of Langerhans. In this condition, many immune cells (T cells, B cells, macrophages and other white blood cells) move into and around the islets. They crowd Read More …

Pancreatic beta cell dysfunction means that the special cells in the pancreas that make insulin are not working properly. These beta cells live in small groups called islets, and their main job is to sense the level of sugar (glucose) Read More …
