Paget's disease is caused by a malfunction in bone formation. Normally, bones are constantly being broken down and rebuilt. With Paget's disease, bones are broken down abnormally fast, and new bone replacement is loose and bulky, instead of strong and compact. These poorly formed bones may become weak. They also may bend over time.
The exact cause of this bone malformation is unknown. Paget's disease may be triggered early in life by a viral infection.
Paget's disease is more common in people who:
Most people with Paget's disease don't have symptoms. For those with symptoms, Paget's disease may cause:
Paget's disease that involves the skull may cause:
Paget's disease doesn't spread to other bones, but the symptoms do get worse over time.
Your doctor will ask about your symptoms and medical history. A physical exam will be done. Your doctor will order a blood test.
Imaging tests take pictures of internal body structures. These are done with:
It is best to begin treatment as soon as possible. Talk with your doctor about the best treatment plan for you.
Medications for Paget's disease include:
