Osteopenia vs. Osteoporosis

osteopenia vs osteoporosis


 Osteoporosis and osteopenia are both conditions that affect the strength and health of your bones. The difference between the two lies in the level of bone damage.

Keep reading to learn more about the differences between these two conditions, how doctors diagnose levels of bone damage, and what you can do to protect your bone health.

Osteopenia and osteoporosis are diagnoses that are used to label bones that have weakened over time. Bone strength can be measured with bone mineral density (BMD) scores. BMD measures the level of minerals — like calcium — in your bones, and a lower score means you’re at an increased risk of fractures or breaks.

Osteopenia can be considered the first step toward osteoporosis. Technically, it’s just a way of saying that your bone density is lower than normal, but not yet causing real problems.

Bone density peaks around age 35, and as your bone density decreases, you may be diagnosed with osteopenia. Typically, this begins to occur with no symptoms at all, but if you begin to break or fracture bones easily, your doctor may decide to measure your bone density.

If you have a lower than normal bone density score — between -1 and -2.5 — you have osteopenia. If you score is lower than -2.5, you may be diagnosed with osteoporosis.

Osteoporosis is the more serious progression of osteopenia. As bone density decreases, the honeycomb-like structure inside your bones becomes even more porous. The more open spaces there are inside your bones, the more density and strength they lose. The light, fragile bones that develop with osteoporosis can place you at a higher risk for fractures and breaks, even when you are doing simple daily activities.

The best way to diagnose osteopenia versus osteoporosis is with BMD testing.
Your T scores will indicate the level of damage in your bones.

Everyone’s bones lose some mass and density over time. After 35, bone strength begins to decline, but there are certain risk factors that can accelerate this process.

People in the following categories are at an increased risk for developing osteopenia and, perhaps eventually, osteoporosis:

Since osteopenia usually develops without symptoms, you may not know that your bones are becoming weaker until you begin to have serious problems or the condition progresses to osteoporosis. A primary care physician may screen you for your risk of osteopenia and osteoporosis. If you have an elevated risk for osteopenia or osteoporosis, your doctor may suggest bone density testing.

Bone density tests are usually done with dual-energy X-ray absorptiometry (DXA/DEXA) scans of the hip and lower spine.

This testing is also recommended for:

  • women over age 65
  • women under age 65 who have evidence of lower bone mass
  • men over age 70
  • men over age 50 with certain risk factors for bone loss

BMD measurements and your FRAX (Fracture Risk Assessment Tool) score are usually used together to get an idea of your overall bone health and guide treatment.

The best treatment for osteopenia is preventing further bone loss and progression of your condition to osteoporosis. While you can’t control your age or genetics, there are some things you can do to help slow bone loss.

Some strategies to reduce your risks of bone density loss include:

  • stop smoking
  • reduce your alcohol consumption
  • eat a balanced diet rich in vitamins and minerals
  • consider vitamin and mineral supplements
  • stay active, especially with weight-bearing exercises

If these strategies aren’t helping, or your condition has already advanced to osteoporosis, your doctor may prescribe you medications or treatments that can help prevent additional bone loss. These may include:

  • bisphosphonates like alendronate (Fosamax) or ibandronate (Boniva)
  • antibody therapies like denosumab (Prolia) and romosozumab (Evenity)
  • hormone medications like procalcitonin
  • hormone replacement therapy
  • vitamin C supplements
  • calcium supplements
  • physical therapy

Bone loss is a natural part of aging, but there are some things — like gender and diet — that can speed the process along.

If your bone density is lower than normal, you may be diagnosed with osteopenia. While this is not quite osteoporosis, the condition is still serious.

With osteopenia, you have time to make changes that can protect your bone health. If your condition has advanced to osteoporosis, talk to your doctor about what you can do to preserve your bone strength and prevent additional loss.
