Pituitary hormones growth hormone excess

Growth hormone excess in children is characterized by extremely rapid linear growth (gigantism). The condition is rare and is most often due to a pituitary tumour. Other causes of tall. stature in children include ... 

Since radioimmunoassays are available, it is now possible to diagnose the early stages of acromegaly and to follow the hormone levels as the disease develops. Furthermore, new types of growth hormone excess have been discovered a disease has been described in which excess growth hormone is observed in the absence of a pituitary hormone. The disease is believed to result from abnormal stimulation of the hypothalamic secretion. 

Excess growth hormone Hypersecretion of growth hormone is commonly caused by a pituitary tumor and results in ... 

Destruction of the pituitary gland may result in secondary hypothyroidism, hypogonadism, adrenal insufficiency, growth hormone deficiency, and hypoprolactinemia. The formation of certain types of pituitary tumors may result in pituitary hormone excess. Pituitary tumors may also physically compress the pituitary and prevent the release of the trophic hypothalamic factors that regulate pituitary hormones. In this chapter, the pathophysiology and role of pharmacotherapy in the treatment of acromegaly, short stature, hyperprolactinemia, and panhypopituitarism will be discussed. 

Somatostatin and its synthetic analogs are used clinically to treat a variety of secretory neoplasms such as GH-secreting tumors of the pituitary. Such tumors can cause gigantism if growth hormone is secreted in excess before the closure of the... 

Gigantism is a condition marked by excessive growth because of the secretion of a growth hormone by a pituitary tumor. Trijntje Keever, born in 1616 in the Netherlands, suffered from the condition. She was the tallest woman in recorded history. When she died at age seventeen from cancer, her height was 8 feet, 4 inches. 

The condition which results from excess growth hormone secretion in adults, the usual cause being a pituitary adenoma. The condition is characterized by increases in bulk of the bones and soft tissues, especially of the jaw, hands and feet. Because growth hormone is involved in glucose homeostasis, impaired glucose tolerance can occur. Acromegaly can be diagnosed biochemically by ... 

A condition that can result from excess growth hormone secretion in childhood usually from a pituitary adenoma. 

A disorder resulting from the oversecretion of growth hormones by the pituitary after most of the bones have stopped growing. The excess of hormone causes overgrowth of the bones in the face, hands, and feet. It may also lead to a diabetic condition and various other abnormalities. 

Excessive secretion of diabetogenic hormones (hormones that maintain or raise blood sugar), including adrenocorticotropic hormone (ACTH) and a growth hormone from the pituitary adrenalin, noradrenalin, and adrenal cortical hormones (mainly cortisol) from the adrenals glucagon from the pancreas and thyroid hormone from the thyroid.
