Obesity May Cause Rheumatoid Arthritis Tough To Spot

According to a study, blood tests to diagnose and monitor rheumatoid arthritis may be thrown off by obesity in women.


Inflammations from excess of weight could lead doctors to think disease is worse in case of a obese women.

According to doctor Michel George, Physicians might assume that high levels of inflammation mean that a patient has rheumatoid arthritis or that their rheumatoid arthritis requires more treatment, when in fact a mild increase in levels of inflammation could be due to obesity instead.

Whereas researchers said that blood tests for C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) can help physicians check the severity of inflammation in rheumatoid arthritis patients.According to previous researches obese women may normally have higher CRP and ESR levels present in them.

According to a research done on 2100 rheumatoid patients data were collected and then compared them from general population. A close study was done over the issue.

Women having higher BMI ( Body Mass Index) was associated with greater CRP  with rheumatoid arthritis. A modest association between ESR and obesity was found.

Whereas in case of men, it is completely reversed.  A lower BMI in men was associated with higher ESR and CRP.

The findings may help improve understanding of the link between weight and inflammation. It may also help doctors learn more about how this relationship differs between women and men, the study authors added.

Later in an article George said that doctors must be careful while interpreting the result of lab tests as both rheumatoid arthritis    and obesity can contribute to inflammation levels.
