Smoking is a major risk factor for developing certain types of arthritis, especially rheumatoid arthritis (RA). It not only increases the likelihood of developing RA but can also make symptoms worse and treatments less effective. Smoking contributes to chronic inflammation, which can damage joints and other tissues over time. It may also slow healing and increase the risk of complications after joint surgery. In osteoarthritis, smoking may impair blood flow to cartilage, accelerating joint damage. Quitting smoking can significantly improve arthritis outcomes and overall health, making it one of the most impactful lifestyle changes for joint health.
