You can have osteoporosis without feeling any different. You may still be walking, working, exercising, and going about your usual routine while your bones gradually weaken.
That is what makes osteoporosis easy to miss. Bone loss usually doesn't cause pain or other obvious symptoms early on. By the time you notice a problem, a minor fall or everyday movement may have caused a fracture.
Changes inside your bones can take years to become noticeable. Understanding what happens during this process, who is more likely to be affected, and how bone loss can be detected may help you act before a serious fracture occurs.
Key Takeaways
- Osteoporosis can weaken bones for years without causing noticeable symptoms.
- As bone loss progresses, bone becomes less dense and its internal structure can weaken.
- A fracture after a minor fall or everyday movement may be the first sign of osteoporosis.
- A DXA scan can detect low bone density before a fracture occurs.
- Treatment and lifestyle changes can help slow bone loss and reduce the risk of future fractures.
Why Doesn't Osteoporosis Cause Symptoms at First?
Your bones are constantly changing. Old bone is broken down while new bone is formed. This process helps maintain the strength and structure of your skeleton.
As osteoporosis develops, more bone may be lost than replaced. Bone mineral density falls, and bone structure can also change. Over time, this leaves the bone weaker and more likely to break.
But bone loss itself usually does not hurt. You can therefore have significant changes in your bones without back pain, joint pain or difficulty moving. This is why osteoporosis is often described as a silent disease. Many people only discover they have it after breaking a bone.
What Is Actually Happening Inside Your Bones?
Healthy bone is not solid and inactive. It is living tissue that is continually being renewed.
Specialised cells break down old bone, while others form new bone. With age and certain health conditions, this balance can shift towards greater bone loss.
The result is not simply less bone. The internal structure can also become less strong. This reduces the bone's ability to withstand normal forces.
The change may happen gradually, so you may not notice it in everyday life.
When Does Bone Loss Become a Problem?
Osteoporosis becomes more apparent when weakened bones can no longer withstand forces a healthy bone would normally handle.
A fracture can occur after:
- A minor fall from standing height
- Bending or lifting
- Coughing or another everyday movement in people with very fragile bones
The hip, spine, and wrist are among the most commonly affected bones.
Spinal fractures can be particularly difficult to recognise. They may cause back pain, loss of height or a change in posture, including a stooped or hunched appearance.
Sometimes, however, a spinal fracture causes few obvious symptoms and may only be discovered during an examination or imaging test.
What Makes Bone Loss Happen Faster?
Age is an important risk factor, but bone loss doesn't happen at the same rate for everyone.
The risk can increase with:
- Menopause and other hormonal changes
- A family history of osteoporosis or hip fracture
- Low body weight
- Inadequate calcium or vitamin D intake
- Smoking
- Heavy alcohol consumption
- Low levels of physical activity
- Certain medical conditions
- Long-term use of medicines such as corticosteroids
Some people develop osteoporosis without having a clear risk factor. This means feeling healthy does not necessarily tell you how strong your bones are.
How Do You Know If Your Bones Are Weak?
Since symptoms may not appear until a fracture occurs, testing can identify bone loss earlier.
A DXA scan, or dual-energy X-ray absorptiometry scan, measures bone mineral density. It commonly assesses the hip and spine and is a quick, painless test.
A DXA scan can help doctors:
- Detect low bone density before osteoporosis develops.
- Diagnose osteoporosis
- Estimate the risk of future fractures.
- Monitor how well treatment is working.
Your healthcare professional may also consider previous fractures, family history, medicines, lifestyle factors and other health conditions when assessing your fracture risk.
Can Osteoporosis Be Treated Once Bone Loss Has Started?
Yes. Treatment aims to slow or stop further bone loss and reduce fracture risk. Depending on your risk, treatment may include exercise, appropriate nutrition, fall prevention and prescription medicines.
One medicine used for osteoporosis is denosumab. It reduces osteoclast activity, the cells that break down bone, which can help reduce bone loss and lower fracture risk in eligible patients.
Olimab injection is an example of a denosumab-containing medicine. Healthcare professionals generally administer denosumab for osteoporosis as a subcutaneous injection every six months.
Treatment needs to be planned carefully. For example, people with advanced chronic kidney disease have a higher risk of severe low blood calcium levels with the medicine, and stopping or delaying treatment without medical guidance can increase fracture risk.
What Can You Do Before a Fracture Happens?
Some of the factors that affect bone health, including age and family history, are beyond your control. Others are not. Regular exercise, adequate calcium and vitamin D intake, and avoiding smoking can all help maintain bone health. Walking and strength training help, but the right level of activity depends on your health and whether you already have osteoporosis.
Pay attention to falls, too. A fall that might leave someone else with a bruise can fracture a person with weakened bones. Keeping floors clear, improving lighting and addressing balance problems can help reduce this risk.
If you have risk factors for osteoporosis, or have broken a bone after a relatively minor fall, do not assume it was simply bad luck. Ask whether you should have your bone density checked.
Conclusion
You may not feel your bones getting weaker, and nothing may suggest anything has changed. That is why osteoporosis can go unnoticed for so long. If you suspect you are at risk, you don't need to wait for a fracture to look into it.
