Acromegaly

What is Acromegaly?

Acromegaly is a rare hormonal disorder that occurs when the pituitary gland produces excessive growth hormone (GH) after puberty. This leads to abnormal growth of bones and soft tissues, particularly in the hands, feet, and face. The condition typically develops slowly and is most often caused by a noncancerous tumor (adenoma) in the pituitary gland.

Causes of Acromegaly

• Pituitary adenomas (benign tumors in the pituitary gland)
• Excessive production of growth hormone (GH)
• In rare cases, tumors in other parts of the body (like the lungs or pancreas) that produce GH or GH-releasing hormone (GHRH)

Symptoms of Acromegaly

• Enlarged hands and feet (rings and shoes may not fit)
• Facial changes (enlarged nose, lips, and jaw)
• Thickened skin and deepened voice
• Joint pain and arthritis
• Enlarged internal organs (heart, liver, kidneys)
• Excessive sweating and body odor
• Fatigue and muscle weakness
• Headaches and vision problems (if the tumor compresses nearby structures)

How is Acromegaly Treated?

Treatment focuses on reducing GH levels, shrinking tumors, and relieving symptoms:

• Surgery (removal of the pituitary tumor)
• Medications (somatostatin analogs, dopamine agonists, GH receptor blockers)
• Radiation therapy (for tumors that cannot be completely removed)

What to Expect During Diagnosis?

• Blood tests (to measure GH and insulin-like growth factor-1 [IGF-1])
• Oral glucose tolerance test (to check GH suppression)
• MRI scans (to detect pituitary tumors)

The Importance of Seeking Medical Help

Acromegaly can lead to serious complications, such as heart disease, high blood pressure, diabetes, and sleep apnea, if left untreated. Early diagnosis and treatment are essential to improving quality of life and preventing long-term damage.
