Arthritis is a broad term that covers a group of over 100 diseases. It has everything to do with your joints — the places where your bones connect — such as your wrists, knees, hips, or fingers. But some types of arthritis can also affect other connective tissues and organs, including your skin.
About 1 out of 5 adults have some form of the condition. It can happen to anyone, but it becomes more common as you age.
With many forms of arthritis, the cause is unknown. But some things can raise your chances of getting it.
Age:- As you get older, your joints tend to get worn down.
Gender:- Most types of arthritis are more common among women, except for gout.
Genes:- Conditions like rheumatoid arthritis, lupus, and ankylosing spondylitis are linked to certain genes.
Excess weight:- Carrying extra pounds makes arthritis in the knee start sooner and get worse faster.
Injuries:- They can cause joint damage that can bring on some types of the condition.
