Precocious Puberty Causes and Symptoms Puberty begins when the brain secretes a hormone that triggers the pituitary gland to release gonadotropins, which in turn stimulate the ovaries or testes to produce sex hormones.
Acromegaly is a disorder in which the abnormal release of a particular chemical from the pituitary gland in the brain causes increased growth in bone and soft tissue, as well as a variety of other disturbances throughout the body.
Less often, hypothyroidism develops when the pituitary gland fails and does not release enough thyroid-stimulating hormone (TSH), which stimulates the thyroid to produce and secrete normal amounts of T4 and T3.
Children with pituitary dwarfism may face thoughtless comments from others on occasion, and the parents' reaction to such comments can strongly determine how the child feels about himself or herself.
Growth hormone deficiency is present at birth, but since the primary symptoms of pituitary dwarfism are height and growth at a reduced rate, the condition is not diagnosed until later in childhood.
In cases of tumor, most commonly craniopharyngioma (a tumor near the pituitary gland), children and adolescents may have neurological symptoms such as headaches, vomiting, and problems with vision.
A careful balancing of all of the hormones produced by the pituitary gland is necessary for patients with panhypopituitarism, making this form of dwarfism complex and difficult to manage.
The anterior pituitary produces six hormones: growth hormone, adrenocorticotropin (corticotropin), thyroid stimulating hormone (thyrotropin), prolactin, follicle stimulating hormone, and lutenizing hormone.
And on the influence of these inconspicuous bodies and of the pituitary body in sustaining arterial blood pressures physiologists have thrown some important light.
The pituitary body probably subserves a like purpose.
