Osteopenia isn’t as serious as osteoporosis—see our posts defining bone loss test scores of osteoporosis -2.5 or osteoporosis -3.0. But it’s also not easy to detect; there aren’t any obvious osteopenia symptoms.
Certain factors, however, can make you vulnerable to osteopenia, meaning that it’s important to preserve your bone density. Specifically, you’re at greater risk for osteopenia if your diet is poor or if you have an eating disorder. In either case, you likely aren’t consuming the necessary nutrients to support bone health. Lack of exercise also raises your risk, as does a family history of osteoporosis.
Besides poor diet, an eating disorder, or lack of exercise, these risk factors can expose us to osteopenia:
- Being underweight
- Undergoing chemotherapy or radiation to treat cancer
- Fracturing a bone after age 50
You also are more vulnerable to osteopenia if you’re taking long-term corticosteroid medications like those used to treat rheumatoid arthritis and asthma (for example, prednisone) or if you regularly take certain corticosteroids and proton-pump inhibitors, or PPIs (which are used to manage gastroesophageal reflux disease).

What Is Osteopenia?
Osteopenia is a term used to describe low bone density that’s not severe enough to be diagnosed as osteoporosis. With osteoporosis, symptoms may turn up that tell you you’re at risk for fractured or broken bones. With osteopenia, symptoms typically don’t turn up to warn you.
In the absence of osteopenia symptoms, a bone density scan is necessary to diagnose osteopenia. (The procedure also will diagnose osteoporosis -2.5 and osteoporosis -3.0.) How does a bone density scan work? It’s a special type of x-ray that measures—as the name suggests—just how dense your bones are. During a scan, physicians will focus on specific areas of the body—the spinal vertebrae, hips, and wrist area—that are more likely to develop osteoporosis.
A bone density scan reports what’s called a T-score, which compares your bone density to that of a healthy adult at the age of peak bone mass (about age 30). A T-score between -1.0 and -2.5 indicates osteopenia.
Both osteopenia and osteoporosis represent a continuum in the process of natural bone loss that occurs in all women after menopause—and also in many older men—as existing bone cells are broken down (called “resorption”) faster than new bone is made.
How to Fend Off Bone Injury
If you have osteopenia, don’t panic—it doesn’t mean you’re at significantly greater risk for sustaining a bone fracture in the near future. It does mean, however, that you should make sure you’re doing what you can to maximize your bone health. Steps you can take include:
- Engaging in weight-bearing exercise (such as walking and lifting weights);
- Ingesting 1,500 milligrams daily of calcium, either in your diet (find it in low-fat dairy and fortified cereals) or through supplementation;
- Taking 700 to 800 international units of vitamin D daily;
- Stopping the habit of smoking;
- Avoiding excessive alcohol.
You also should discuss with your doctor the pros and cons of starting an anti-resorptive medication like alendronate (Fosamax) or ibandronate (Boniva)—generally recommended if your T-score is nudging close to osteoporosis -2.5 or if you have a major risk factor for developing osteoporosis in the next few years.
