Blood in the urine may occur after running, but this situation is generally physiological. However, patients with urinary tract stones or tumors may also have an increase in hematuria after strenuous exercise, which is generally considered pathological.
Blood in urine after running is usually caused by physiological reasons. During exercise, the kidneys may have some vibration or slight trauma, which causes the rupture of small blood vessels in the kidneys, forming the occurrence of blood in urine.
Alternatively, it is also possible that during running, blood flow to the kidneys is reduced, while blood flow to the heart and lungs in the body is increased. Reduced blood flow to the kidneys not only causes a decrease in the distribution of blood flow to the kidneys, but may also cause a decrease in the filtration rate of the glomeruli.
Especially after strenuous exercise, such as running for too long, the flow of blood through the kidneys will be reduced, glomerular ischemia, resulting in an increase in the local permeability of the glomerulus, causing the leakage of red blood cells and the formation of blood in the urine occurs.
In addition, patients with urinary tract stones or tumors may also cause an increase in hematuria after strenuous exercise, which is generally pathological.
Therefore, we need to pay attention to appropriate exercise, do not run strenuously, after the occurrence of hematuria should go to the hospital, after clarifying the cause of the disease under the guidance of the doctor to carry out the appropriate treatment and therapy.
