ESR stands for erythrocyte sedimentation rate, which is a measure of how quickly red blood cells settle at the bottom of a test tube. ESR is not a disease, but rather a marker of inflammation or infection in the body.
In general, the underlying condition that is causing an elevated ESR is what needs to be treated, rather than the ESR itself. For example, if the elevated ESR is due to an infection, then treating the infection with antibiotics or antiviral medications will usually lead to a decrease in the ESR. Similarly, if the elevated ESR is due to an autoimmune condition such as rheumatoid arthritis or lupus, then treatment with immunosuppressive medications can often help lower the ESR.
In summary, ESR is not a condition that can be treated directly, but rather a marker of underlying inflammation or infection that can often be treated with appropriate medical therapy.
