What Is Paget Disease of the Bone?
Paget disease of the bone is a condition that affects the body’s normal bone renewal process. Healthy bone is constantly broken down and rebuilt, but with Paget disease, this process happens too quickly and unevenly.
Over time, affected bones can become larger, weaker, and more likely to break. The condition most often develops in adults over age 50 and may affect the pelvis, spine, skull, or legs.
The exact cause of Paget disease is not fully understood. Genetics may play a role, and researchers continue to study possible environmental or viral factors. The condition becomes more common with age.
Symptoms
Some people with Paget disease do not notice symptoms right away. Others may develop pain or changes in the shape of affected bones.
Common symptoms may include:
- Bone pain
- Joint pain or stiffness
- Enlarged or misshapen bones
- Increased risk of fractures
- Arthritis near affected joints
- Warmth over the affected area
- Numbness or weakness if bones press on nearby nerves
How Is It Diagnosed?
Your healthcare provider will begin with a physical exam and review of your symptoms and medical history. Blood tests can help detect increased bone activity, especially by measuring alkaline phosphatase levels.
Imaging tests are often used to confirm the diagnosis and evaluate affected bones. These may include:
- X-rays
- Bone scans
- Occasionally, a bone biopsy if more information is needed
Early diagnosis can help reduce the risk of complications and support better long-term bone health.
How Is It Treated?
Treatment depends on your symptoms, overall health, and how much of the bone is affected. Many people respond well to medications and supportive therapies.
Treatment options may include:
- Bisphosphonate medications to slow abnormal bone changes
- Medicines to help manage pain
- Physical therapy to improve movement and strength
- Assistive devices to reduce stress on joints and bones
In more advanced cases, surgery may be recommended to repair fractures, correct deformities, or replace damaged joints.
With proper care, many people are able to manage symptoms and stay active. Regular follow-up visits may help monitor the condition and prevent complications.
