The blood sedimentation rate of 30 mm/h is higher than normal (normal range: 0-15 mm/h for men, 0-20 mm/h for women), which may be due to physiological reasons (pregnancy, age >60 years, etc.), or due to disease factors (infections, tumors, immune system diseases, etc.), and needs to be analyzed specifically. 1. Physiological reasons: high blood sedimentation may occur in pregnancy, age >60 years, etc. Regular review is sufficient and no special treatment is needed. 2. Disease factors: Inflammation caused by various pathogenic bacterial infections, tumors (esophageal cancer, gastric cancer, etc.), immune system diseases (rheumatoid arthritis, systemic lupus erythematosus, etc.), etc., can all appear to have rapid blood sedimentation, and the clinical symptoms can be fever, emaciation, arthralgia and other related symptoms, routine blood tests, histopathological biopsy, and antinuclear antibody spectrum can assist in the definitive diagnosis. Blood sedimentation of 30 mm/h may be physiological or due to disease, and should be closely monitored. If there is any other discomfort or progressive acceleration of blood sedimentation, timely consultation is recommended.
