What is the cause of exercise-induced hematuria?

Exercise-induced hematuria often occurs in the absence of any pathological changes in the urinary system and in some healthy people. It is mainly due to the severe vibration or impact of the kidneys during exercise, causing traumatic hematuria. Therefore, you should also pay attention to it when exercising.

1. Causes of exercise-induced hematuria

In people who are completely healthy and have no pathological changes in the urinary system. The main reason for hematuria is that the kidneys are traumatized by severe vibration or impact during exercise. This trauma can rupture the blood vessels in the kidneys and cause hematuria. For example, after boxing, about 28% of people experience hematuria, which belongs to this type. Some sports events

The possibility of renal trauma is very small, such as in rowing sports, but hematuria may occur after exercise. The reason for this may be that the blood distribution throughout the body is adjusted during exercise, the blood flow to the kidneys is reduced, and the glomerular filtration rate is reduced. The more intense the exercise, the less blood flows through the kidneys, and a large amount of blood flows to the active parts of the body, such as the heart, lungs and muscles, to facilitate intense exercise. Renal blood flow decreases, glomeruli become ischemic and hypoxic, and permeability increases. At the same time, the increase of lactic acid in the blood also increases the permeability of the glomeruli. In addition, renal blood circulation disorders and congestion during exercise can also increase glomerular permeability, allowing red blood cells to pass through the blood vessel walls into the urine, resulting in hematuria. Long-distance running and prolonged upright exercise can cause kidney ptosis, obstruction of renal venous return, and renal congestion, which can also cause hematuria.

2. Treatment/exercise hematuria

1. For those with macroscopic hematuria, regardless of whether there are other accompanying symptoms, exercise should be stopped. For athletes with asymptomatic microscopic hematuria, exercise load should be reduced and continued observation should be conducted.

2 Try hemostatic drugs, such as vitamin K, C, and Anluoxue

3. For those with accompanying dysfunction, ATP or vitamin B12 can be injected intramuscularly once a day, and ten times constitute a course of treatment. 4. For hematuria caused by organic nature and trauma, active treatment should be carried out according to the cause, and normal training is generally not allowed.

Precautions/exercise hematuria

1. Follow the scientific principles of training. The load and training intensity should be gradually increased. Avoid suddenly increasing the load and training intensity. Do a good job of warming up the whole body and waist.

2. Reasonably arrange the drinking water system during training and competition, and replenish water appropriately during intense training and competition

3 Pay attention to changes in the external environment and adjust the intensity.

Exercise-induced hematuria is transient hematuria that occurs in healthy people after exercise, although no other cause is found after detailed examination.
