    Study Notes

    Pituitary Gland and Acromegaly

    • The anterior pituitary gland secretes several hormones, including growth hormone (GH), adrenocorticotropic hormone (ACTH), thyroid-stimulating hormone (TSH), prolactin, follicle-stimulating hormone (FSH), and luteinizing hormone (LH).

    Acromegaly

    • Acromegaly is a hormonal disorder caused by excessive production of growth hormone (GH) after normal growth has stopped, usually due to a benign tumor on the pituitary gland.
    • The most common type of pituitary adenoma is a non-cancerous tumor that produces excessive GH, leading to acromegaly.

    Clinical Manifestations of Acromegaly

    • Clinical manifestations of acromegaly include joint pain and limited joint mobility, sleep apnea, excessive sweating, and enlarged hands and feet.
    • Other symptoms may include coarse facial features, joint deformities, and changes in voice and skin texture.

    Diagnosis of Acromegaly

    • Acromegaly is diagnosed through a combination of physical examination, medical history, and laboratory tests, including GH level measurement and pituitary gland imaging.
    • The oral glucose tolerance test (OGTT) is used to evaluate GH response in acromegaly.

    Epidemiology of Acromegaly

    • The most common age range for diagnosis of acromegaly is 40-50 years.
    • The main reason for the overproduction of GH in acromegaly is a benign tumor on the pituitary gland.
