Running and urinating blood and then normal the next day, may be related to the strenuous exercise.
The cause of blood in urine is divided into physiological and pathological. Physiological includes strenuous exercise, menstrual blood contamination of urine, etc. Pathological includes chronic glomerulonephritis, urinary tract stones, urinary tract infections, etc., which need timely treatment.
During strenuous exercise, due to blood redistribution, the blood supply to the joints and muscles of the whole body increases, while the blood supply to the kidneys decreases, resulting in renal ischemia and hypoxia, and the glomeruli are more sensitive to ischemia and hypoxia, a transient injury occurs, the glomerular permeability increases, and the blood leaks out of the red blood cells, which will show the symptom of hematuria after exercise, and will usually return to normal after rest.
After running blood in the urine the next day and normal patients do not need to worry too much, usually belong to the normal phenomenon, but repeated occurrence of the symptom should be suspected of pathological factors, should go to the hospital in a timely manner to consult, timely treatment.
