Which are the symptoms of Acromegaly?

TL;DR: Acromegaly is a rare, chronic disorder caused by excessive growth hormone (GH) production, typically from a benign pituitary tumor, resulting in the gradual enlargement of bones, soft tissues, and internal organs. Common symptoms include the thickening of hands and feet, facial feature changes, joint pain, and systemic issues like sleep apnea or cardiovascular strain, which often develop slowly over many years.

What are the primary symptoms of acromegaly?

The clinical presentation of acromegaly is often insidious, meaning symptoms develop so slowly that patients and their families may not notice changes for years. The most characteristic signs involve the overgrowth of skeletal and soft tissues. Patients frequently report that their rings no longer fit, their shoe size has increased, or that their hat size has changed. Facial changes are also hallmark features of acromegaly, including a protruding jaw (prognathism), spacing of the teeth, and thickening of the skin and lips. Because acromegaly affects the entire body, it also leads to metabolic and systemic changes, such as excessive sweating (hyperhidrosis) and oily skin, which are reported by a significant portion of our 112 acromegaly community members at DiseaseMaps.org.

How do symptoms affect daily quality of life?

While physical changes are the most visible, the symptoms that most severely impact daily quality of life are often internal. Chronic fatigue, persistent headaches, and debilitating joint pain (arthropathy) are common. Furthermore, the enlargement of soft tissues in the throat can lead to obstructive sleep apnea, causing severe daytime exhaustion and cognitive impairment. Many individuals with acromegaly also experience numbness or tingling in the hands due to carpal tunnel syndrome, which is frequently a secondary complication of the tissue swelling associated with the disease.

What are the early warning signs and progression patterns?

Early warning signs are often subtle and easily dismissed as normal aging or weight gain. Recognizing these signs early is crucial for preventing long-term complications. Key indicators include:

• Unexplained increase in glove, ring, or shoe size.


• New or worsening snoring and morning headaches.


• Persistent joint pain that does not respond to standard anti-inflammatories.


• Changes in bite or dental alignment.


• Noticeable deepening of the voice due to thickening of vocal cords.

Over time, if left untreated, acromegaly can progress to cause more serious systemic issues, including hypertension, diabetes mellitus, and an increased risk of cardiovascular disease or colon polyps. The severity of these symptoms varies greatly depending on the duration of hormone excess and the individual’s physiological response.

When should I seek immediate medical attention?

While acromegaly is a chronic condition, certain symptoms warrant urgent evaluation. You should consult a physician immediately if you experience sudden, severe headaches, rapid changes in vision (such as peripheral vision loss, which may indicate the tumor is pressing on the optic chiasm), or sudden onset of weakness. These can be signs of "pituitary apoplexy," a rare but medical emergency involving sudden bleeding or infarction of the pituitary tumor.

Next steps

• Consult an endocrinologist experienced in pituitary disorders to discuss hormonal testing (IGF-1 and GH levels).


• Request an MRI of the pituitary gland to evaluate for the presence of an adenoma.


• Join our community of 112 members at DiseaseMaps.org to share experiences and find support from others living with this condition.


• Keep a symptom log, including photos of your face and hands over time, to help your medical team track disease progression.
