Blood sedimentation of 26mm/h indicates that the blood sedimentation is increasing rapidly, and the possible causes are physiological acceleration, tissue deformation and necrosis, rheumatic immune disease, etc. The normal value of blood sedimentation is 0~15mm/h for men and 0~20mm/h for women. The normal value of blood sedimentation is 0~15mm/h for men and 0~20mm/h for women. 26mm/h indicates that the blood sedimentation is increasing fast. 1. Physiological acceleration: the body is in a certain normal situation, which will lead to accelerated blood sedimentation, such as women in the menstrual period or pregnancy. Children or the elderly may also experience increased sedimentation rate. 2. Tissue degeneration and necrosis: myocarditis, bacterial or septic inflammation, myocardial infarction, etc. can lead to degeneration and necrosis of the tissue cells, which will lead to accelerated blood sedimentation. 3. Rheumatic immune diseases: such as rheumatoid arthritis, systemic lupus erythematosus, etc. will lead to a relative or absolute increase in plasma immunoglobulin, resulting in accelerated blood sedimentation. There may also be other reasons for increased blood sedimentation, such as malignant tumors, etc. It is recommended to go to the hospital in time, improve the examination to clarify the cause of the disease, and then give targeted treatment or therapy.
