Sedimentation 35 means that the blood sedimentation is accelerated, which may be physiologically accelerated, or it may be caused by disease factors such as various inflammation, tissue damage, and necrosis, anemia and so on. 1. Physiological acceleration: blood sedimentation is accelerated during menstruation due to the endometrial breakage and bleeding; blood sedimentation is accelerated due to the increase of fibrinogen in the blood of the elderly; blood sedimentation is also accelerated after meals and strenuous exercise. 2. Inflammation: when there is inflammation in the body, the immunoglobulin and fibrinogen in the blood will increase and lead to accelerated blood sedimentation, such as pneumonia, myocarditis, active tuberculosis and rheumatic fever. 3. Tissue injury and necrosis: major surgery leads to injury, myocardial infarction, pulmonary infarction, severe trauma and other diseases can also accelerate the blood sedimentation. 4. Anemia: Anemia leads to decreased hematocrit and accelerated blood sedimentation. There may be other reasons for accelerated blood sedimentation. If the blood sedimentation remains elevated and does not decrease, it is recommended to consult a doctor in time to clarify the cause of the disease.
