Many people with RA experience persistent fatigue.
However, experts do not fully understand why people with RA have such high rates of fatigue.
Although RA causes high levels of inflammation, experts are unsure if it is to blame for fatigue. Studies have not been able to show causation between the two factors.
A 2019 study examined factors that made people with RA more likely to experience fatigue. They found that pain, poor sleep quality, mental health challenges, and disability all increased a person’s likelihood of fatigue.
While the exact cause of RA-related fatigue is not yet understood, people may benefit from knowing whether they are at a particularly high risk of experiencing it.
