Sleep apnoea syndrome is highly prevalent in acromegaly and only partially reversible after biochemical control of the disease

SAS can persist after recovery of acromegaly in several patients. Given the negative prognostic significance of this respiratory disorder, polysomnography should be included as routine procedure in the work-up of the acromegaly, even if in remission, being mandatory in those patients considered at high risk (elderly males, overweight, diabetic). Appropriate intensive treatment should be implemented to minimize the clinical impact of SAS in acromegaly.
