What is acromegaly?
When your pituitary gland makes too much growth hormone, abnormal growth occurs. This
is called acromegaly. The abnormal growth starts in your hands and feet, as soft tissue
begins to swell. This rare disease affects mostly middle-aged adults. It can lead
to severe illness and even death if not treated.
In children, too much growth hormone causes a condition called gigantism. This leads
to a large increase in height.
What causes acromegaly?
Acromegaly happens when the pituitary gland makes too much growth hormone for a long
time. Several reasons may cause this extra amount of hormone to be made. The most
common is a noncancer (benign) tumor in the pituitary gland. Tumors in other parts
of the body that cause an increase in growth hormone can also cause acromegaly. But
that is rare.
What are the symptoms of acromegaly?
Each person’s symptoms may vary. They depend on how long you have had the disease.
Symptoms may include:
Swelling of your hands and feet. You may find your rings no longer fit and you need
to buy larger shoes.
Larger lips, nose, and tongue, as your bones grow
Larger jaw that sticks out more (protrudes)
Thicker body hair
Thicker, darker skin and skin tags
More sweat and body odor
Larger chest as your ribs get thicker
Increased size of your heart and other organs
Strange feelings and weakness in your arms and legs, including carpal tunnel syndrome
Snoring and breaks in breathing during sleep (sleep apnea) from thickened tissue around
Lack of energy (fatigue) and weakness
Loss of eyesight or double vision
Irregular menstrual cycles (women)
Breast discharge (women)
Men unable to have or maintain an erection (impotence)
Enlarged thyroid gland
These symptoms may look like other health problems. Always see your healthcare provider
for a diagnosis.
How is acromegaly diagnosed?
Symptoms may not be seen right away. So acromegaly is often not found until years
later. Your healthcare provider will take your health history and give you a physical
exam. In addition, you may need:
Photos taken regularly over the years. These are used to see physical changes.
Blood tests. These are done to check your growth hormone level and levels of other related hormones.
X-rays. These are done to see bone thickening.
MRI or CT scan. These can help find tumors.
How is acromegaly treated?
Treatment will depend on your symptoms, age, and general health. It will also depend
on how severe the condition is.
Treatment of acromegaly depends on what is causing the disease. The main goal of treatment
is to get your growth hormone levels back to normal.
Most cases are caused by benign tumors on the pituitary gland. Others are caused by
tumors in the pancreas, lungs, or adrenal glands. Treatment may include:
What are possible complications of acromegaly?
If acromegaly isn’t treated, it can lead to several problems. These may include:
The disease also raises your risk for colon polyps. These are small growths on the
lining of your colon. They may lead to colorectal cancer.
Living with acromegaly
You should see your healthcare provider on a regular basis. Your provider can make
sure your treatment is working. Your provider can also check for any problems. Early
treatment can then be started if needed.
When should I call my healthcare provider?
Tell your healthcare provider if your symptoms get worse or you have new symptoms.
