The Condition"...level is high, even when patient receives glucose load; diabetes occurs in 30% of cases; elevated IGF-1; elevated prolactin level; elevated liver function; elevated blood urea nitrogen; elevated phosphorus; decreased free thyroxine; elevated thyroid stimulating hormone) and through imaging (MRI shows pituitary tumor)..."

The Condition"...Since pituitary tumors (usually benign) are the most common cause of this condition, other areas controlled by the pituitary are often affected, such as Prolactin and thyroid hormones..."

The Condition"...tongue problems; big forehead; darkened skin in armpits; widely spaced teeth; oily, tough skin; skin pigmentation changes - darker or lighter; excessive hair growth in females; high blood pressure; goiter (enlarged thyroid); kyphosis or loss of disc spaces of the spine; osteoporosis; osteoarthritis), through laboratory findings (growth hormone level is high, even when patient receives glucose..."

excessive activity of the pituitary gland (especially overactivity of the anterior lobe which leads to excess secretion of growth hormone)

The Condition"...Symptoms of excess growth hormone include ... Sleep Apnea..."

Hyperpituitarism is the result of excess secretion of adenohypophyseal trophic hormones most commonly by a functional pituitary adenoma. Other causes are hyperplasias and carcinomas of the adenohypophysis, secretion by non-pituitary tumours and certain hypothalamic disorders.
