Lupus and Osteoporosis: What You Should Know

People living with systemic lupus erythematosus, or lupus, may be at increased risk for developing other health conditions. One of those is osteoporosis, or the gradual weakening of the skeleton that could lead to fractures of the hip, spine and other bones. The condition is much more common in women than men; roughly 50% of all women and 25% of men over the age of 50 will sustain an osteoporosis-related fracture in their lifetime. That’s largely the result of the loss of estrogen, an important hormone for bone growth, during menopause.

Osteoporosis is also associated with other factors, including the use of certain medications and nutritional deficiencies, particularly calcium and vitamin D.

It’s important to understand the relationship between lupus, bone health and osteoporosis, as well as ways to lower your own risks and manage osteoporosis.

Risk Factors for and Effects of Osteoporosis

Inflammation caused by lupus affects many parts of the body, including the skeleton, and contributes to the loss of bone.

Studies have found that compared to healthy women, women with lupus have an increase in the bone loss that leads to osteoporosis, including as much as a fivefold increase in the risk of a bone fracture. Women with lupus also suffer from the loss of height as well as bone around the teeth in the jaw and skull.

Additional factors putting people with lupus at an increased risk for osteoporosis include:

  • use of corticosteroids or glucocorticoids, which decrease the body’s ability to absorb calcium and weaken bone mineralization
  • kidney disease, which affects nearly 30% of people with lupus
  • reduced physical activity due to lupus symptoms
  • menopause, early menopause, or having no menstrual periods
  • family history of osteoporosis
  • tobacco or nicotine use in any form
  • excess drinking of alcohol

Furthermore, approximately 10% of people with lupus develop a condition called avascular necrosis (also known as osteonecrosis) as a result of their use of steroids. The condition involves reduced blood supply to the bone, generally in the hips, along with increased swelling and pressure. Bone weakens, causing tiny cracks, which lead to joint pain, decreased movement within the joint and muscle spasm. At the end stage, the bone collapses under stress.

How to Lower Your Risk

There are ways to protect yourself from osteoporosis and its effects. If you have been diagnosed with osteoporosis or osteopenia, a less advanced form of bone loss that can progress to osteoporosis, your doctor may recommend a variety of medications that reduce the risk of fracture. These treatments can either slow additional loss of bone or, in some cases, even stimulate the formation of new bone. Your rheumatologist can advise you on which of these therapies is right for you.

Supplements with calcium and vitamin D can keep bones strong, as can regular weight-bearing exercise like running, hiking, walking, playing tennis or other sports. Stopping smoking and reducing your intake of alcohol also can help, as these habits are bad for bone.
