Experts don't know exactly how common ankylosing
spondylitis is, because the condition is often not diagnosed. The prevalence
(how common it is) differs among groups of people.
spondylitis is more common in men than in women. It is often found in certain
ethnic groups, such as Inuits of Alaska and Siberia. It is much less common in
people whose family is Japanese or African.1
When you have arthritis pain, you need relief. But with so many warnings in
the news about painkillers, it's hard to know the best choice. Many medications
that ease arthritis pain have the potential for health risks, including
increased risk for heart attack, stomach problems, or infections.
You have difficult decisions to make, whether you're fighting pain from
osteoarthritis that comes with age -- or pain from rheumatoid arthritis, a
debilitating immune disorder. Do you somehow tough out...
The only clear risk factor for ankylosing spondylitis is having a close
family member who has the condition. About 15 to 20 out of 100 people with ankylosing
spondylitis have at least one family member who has it.1 Having a gene known as HLA-B27 and having frequent infections
of the gastrointestinal system (stomach and other organs of digestion) may also
increase your risk.
