Hi,
Welcome to HealthcareMagic forum
First let me begin by saying yes,
erythrocyte sedimentation rate (ESR) is a non specific marker of inflammation. A specific possibility / cause cannot be confirmed without further investigations.
Second an ESR value of less than 100 usually suggests benign problems which sometimes are not considered significant at all. So I would not expect a major serious inflammation which is causing this persistently high ESR value to be happening within you.
Third iron deficiency is associated with anemia. And anemia can also cause high ESR.
So based on the details provided, your mild rise in ESR is most likely associated with
iron deficiency anemia. You may confirm this by checking your
hemoglobin levels.
If iron deficiency is persistently low, that is concerning and you need to be evaluated for that. A competent
hematologist can help you in this case. You would need stool test to rule out microscopic blood loss begin with. Other test can follow the stool report.
I hope you have been started on
iron supplements. Talk with your hematologist to take this case forward.
Hope this answers your query.
Regards
