Immune aging may link osteoporosis and osteoarthritis
A scientific review proposes that the chronic inflammation of aging and changes in immune cell metabolism help explain why osteoporosis and osteoarthritis often appear together in older adults.

What the research shows
Traditionally, osteoporosis is attributed to imbalanced bone renewal and falling estrogen, and osteoarthritis to mechanical wear of cartilage. The review's authors say these explanations do not account for why the two diseases so often occur together, and point to aging-related inflammation, immune imbalance and oxidative stress as a common background.
What it means
The idea is that bone and joints do not become diseased in isolation but influence each other through immune signals. If confirmed, future research could look for ways to address both conditions at once.
How to read it with care
This is a review, not a new study. The authors themselves write that most evidence comes from studies of each disease separately and that there is not yet proof of a shared causal mechanism in people.
