What is it?

What is Paget’s disease?

Paget’s disease is a disorder that causes bones to grow too large and weaken. You can have Paget’s disease in any bone in your body, but it usually affects the:

  • Spine.
  • Pelvis.
  • Skull.
  • Leg bones.

The changes of bone tissue causes affected bone to weaken leading to:

  • Bone pain.
  • Misshapen bones.
  • Fractures.
  • Arthritis in the joints near the affected bones.

Paget’s disease usually only affects one bone or several bones, but it does not affect the entire skeleton.

Who gets it?

Who gets Paget’s disease?

The disease is more common in older people and those of northern European heritage. Men are more likely than women to have the disease. Research suggests that a close relative of someone with Paget’s disease is more likely to develop the disease than someone without an affected relative.

Many people do not know they have Paget’s disease because they have only mild symptoms. For others, signs and symptoms can include:

  • Pain.
  • Enlarged bones.
  • Broken bones.
  • Damaged cartilage in joints.

If you have Paget’s disease in your leg bones, you may also have bowed legs. Your spine might curve if the disease is in the bones of the spine.

People with Paget’s disease in the bones of the skull sometimes have:

  • Headaches.
  • Hearing loss.
  • Large head size.

Symptoms get worse slowly, and the disease does not spread to other bones.

What causes it?

Doctor’s diagnose Paget’s disease with x-rays. Your doctor may also order:

  • A blood test to check for alkaline phosphate, an enzyme. People with Paget’s disease have too much of this enzyme.

In rare cases your doctor may perform a bone biopsy. During this test, the doctor removes a small sample of bone and looks at it under a microscope.

Living With It

Living with Paget’s disease

If you have Paget’s disease, the outlook is usually good. When you follow your doctor’s treatment plan, you may lower the chance of major changes in your bones. Treatment can help you manage your symptoms but does not cure the disease.

Healthier Bones

It is never too early or too late to take care of your bones. There are many things that can help you improve your bone health:

  • Eat a well-balanced diet rich in calcium and vitamin D. Good sources of calcium include:
    • Low-fat dairy products.
    • Foods and drinks with added calcium.
  • Good sources of vitamin D include:
    • Egg yolks.
    • Saltwater fish.
    • Liver.
    • Milk with vitamin D.

Some people may need to take nutritional supplements in order to get enough calcium and vitamin D.

  • Get plenty of physical activity. Like muscles, bones become stronger with exercise. The best exercises for healthy bones are strength-building and weight-bearing, such as:
    • Walking.
    • Climbing stairs.
    • Lifting weights.
    • Dancing.

Try to get 30 minutes of exercise each day. Before starting a new exercise plan, talk with your doctor. 

Maintain a Healthy Lifestyle

  • Live a healthy lifestyle. Don’t smoke, and, if you choose to drink alcohol, don’t drink too much.
  • Maintain a healthy weight is particularly important if Paget’s has led to arthritis of the weight-bearing joints, such as the hip or knee. Excess weight can mean more stress—and pain—for affected joints.
  • Prevent falls by:
    • Checking your home for dangers like loose rugs and poor lighting.
    • Installing grab bars and hand rails.
    • Using nonskid mats in the bathroom and tub.
    • Seeing your doctor regularly to have your vision checked.
    • Increasing your balance and strength by exercising every day.
  • Seek support. It is important to take care of your physical and mental health. Living with Paget’s disease can be stressful. You may find it helpful to speak to:
    • Social workers.
    • Counselors.
    • Mental health professionals.
    • Other people with the disease.

Your doctor can help you find counselors or a support group.
