Overview

Acromegaly (say "ack-roh-MEH-guh-lee") is a condition in which the body makes too much growth hormone. This causes abnormal growth of bones and tissues. It is noticed mostly in the hands and feet. It can also affect internal organs, such as the heart. The condition also can cause changes in the face. For example, the brow and lower jaw can grow and stick out, and the nasal bone can get bigger. In most cases, these changes happen slowly over many years.

People with the condition may have a greater risk of certain diseases such as diabetes, high blood pressure, and arthritis. And they may have other problems such as sleep apnea and headaches. This condition can be painful. This is because the bones may keep growing after they have reached their adult size.

Acromegaly is often caused by a tumour of the pituitary gland, which is where growth hormone is made. But the tumour isn't cancer. It can be treated with medicine, surgery, radiation treatment, or some combination of these. Rarely, a tumour in a different part of the body, such as in the pancreas gland, can cause the pituitary gland to make too much growth hormone. This also can lead to acromegaly. Treatment may stop some abnormal growth, but bones don't go back to normal after the treatment.

How can you care for yourself at home?

• Be safe with medicines. Take your medicines exactly as prescribed. Call your doctor or nurse advice line if you think you are having a problem with your medicine.
• This condition can change how you look. If you have trouble dealing with these changes, talk to your doctor to find a support group. Talking to other people who are going through the same thing can be helpful.
