If you suspect that a patient may have acromegaly, what test should you order? The single best screening test for acromegaly is the plasma level of IGF-1. Unlike GH levels, which are pulsatile and higher at night, samples can be drawn any time of day. In adults, acromegaly is essentially the only condition that causes …
Does Sleep apnea occur in acromegaly Sleep apnea occurs in 50% to 70% of patients with acromegaly. It can result from soft tissue overgrowth of the upper airway or to altered central respiratory control. Sleep apnea may contribute to morbidity and mortality in acromegaly by producing hypoxia and pulmonary hypertension.
What is the cause of death in patients with acromegaly? Acromegaly increases cardiovascular and metabolic risk factors, including hypertension, glucose intolerance, cardiomyopathy, and sleep apnea. The mortality from inadequately treated acromegaly is about double the expected rate in healthy age-matched subjects. Major causes of death include hypertension, cardiovascular disease, heart failure, and diabetes. Improved treatment …

Clinical features of excessive production of Growth Hormone in adults In adults, excessive GH causes acromegaly. Acromegaly is rare, with an incidence of approximately five cases per million people per year, and often progresses gradually and insidiously. The pathologic and metabolic effects of acromegaly are summarized in the below table.
What are the clinical features of excessive Growth Hormone in children? In children who have not yet undergone puberty and whose long bones still respond to GH, excessive GH causes accelerated linear growth. The result is gigantism.
