Osteoarthritis vs. Osteoporosis: What’s the Difference?
As we age, it’s common to experience aches and pains, especially in Rochester, where the weather constantly changes. But not all aches mean the same thing.
Two of the most common bone and joint conditions—osteoarthritis and osteoporosis—are often confused, even though they affect the body differently. So, what’s the difference? And how can you protect yourself from both?
The Difference Between Osteoporosis and Osteoarthritis
Osteoporosis causes weak and brittle bones, making them more likely to break. It occurs when the body loses too much bone, makes too little, or both. While it doesn’t cause joint pain directly, it can lead to fractures, most commonly in the spine, hips, and wrists.
Osteoarthritis affects joints, not the bones themselves. It’s a degenerative disease that wears down the cartilage that cushions your joints. Over time, this leads to joint pain, swelling, and reduced mobility.
What causes osteoporosis or osteoarthritis?
Osteoporosis Causes: Risk factors include aging, low calcium or vitamin D, smoking, family history, inactivity, and certain medications or health conditions. Osteoporosis is most common in postmenopausal women but can occur in men, too.
Osteoarthritis Causes: Typically develops with age or joint overuse, but injuries, obesity, and family history can also increase your risk.
Osteoarthritis Symptoms
According to Susan McDowell, MD, an orthopaedic surgeon with UR Medicine, osteoarthritis usually develops gradually but then might hurt suddenly without an injury. Symptoms include:
- Joint pain during or after movement
- Stiffness, especially in the morning or after inactivity
- Swelling and tenderness in the joints
- Decreased range of motion
- Bone spurs around affected joints
Osteoporosis Symptoms
One of the most dangerous aspects of osteoporosis is that it often has no noticeable symptoms until a bone breaks. Some warning signs may include:
- A fracture that occurs more easily than expected
- Loss of height over time
- Stooped posture due to bone loss
Preventing Osteoarthritis and Osteoporosis
The good news? You can take steps to prevent osteoporosis and osteoarthritis and/or slow their progression.
Keep in mind these healthy habits for strong bones and joints:
- Eat a balanced diet, focusing on sources of calcium and vitamin D.
- Try out weight-bearing and resistance exercises to build bone strength and protect joints.
- Maintain a healthy weight.
- Avoid smoking and limit alcohol, which can weaken bones.
- Talk to your provider about supplements or medications that may help if you're at risk.
When to Seek Care
If you're noticing symptoms like persistent joint pain, stiffness, or back pain—or if you're at increased risk for bone loss—it’s time to talk to your healthcare provider.
Early diagnosis and preventive care are key to managing both osteoporosis and osteoarthritis. UR Medicine orthopaedic providers recommend personalized strategies for treating and preventing bone conditions.
Whether you’re feeling the first signs of joint pain or want to stay ahead of age-related bone changes, taking preventative action can help protect your mobility, comfort, and independence for years.
