Endocrinology CME

Acromegaly is an endocrine disorder characterized by dysregulated hypersecretion of growth hormone (GH), usually caused by a GH-secreting, pituitary adenoma and leading to an overproduction of insulin-like growth factor 1 (IGF-1). Estimated to have a prevalence of 2.8 to 13.7 cases per 100,000, acromegaly is not as common as other endocrine disorders. However, its incidence is increasing, and it has a significant impact on patient quality of life, with clinical features that include: acral enlargement; facial feature and oral changes; headache; significant fatigue, including daytime sleepiness; hyperhidrosis; oily and thicker skin; weight gain; and arthralgia. Approximately 25 percent of people with acromegaly have elevated blood pressure, and 50 percent have evidence of insulin resistance, putting them at risk of developing type 2 diabetes in future. The mortality rates of acromegaly patients are three times higher than the general population, with most dying from respiratory or cardiac complications.
