Scientific exercise is an important guarantee to improve physical fitness and enhance immunity, but unscientific vigorous exercise is most likely to damage the kidney. Because of the fragile texture of the kidney, the impact and violent vibration of external forces will cause kidney contusion and kidney injury. Very slight kidney contusion can recover by itself, but if waist pain is unbearable and even hematuria is found, you should seek medical treatment in time. Once the condition is delayed, it will bring very serious consequences.
Severe exercise causes kidney contusion
Guo, a 20-year-old student, likes sports very much on weekdays. Every day after dinner, he goes to the residential fitness center downstairs. The day before yesterday, he went to the horizontal bar as usual to do the pull-up. After doing it for several times, Guo felt his arm jerk and suddenly lost his strength. Guo involuntarily released the horizontal bar and fell heavily to the ground.
A burst of unbearable pain in the waist hit Guo, and the neighbor saw him and sent him to the hospital. Upon examination, Guo was diagnosed as "right kidney contusion".
Xiao Lin, a 16-year-old high school student, has encountered similar situations. Xiao Lin is a sports specialty student who participates in the long-distance race held by the school every year. This year, Xiao Lin reported a very confident project - the 5000-meter long-distance race. After the start, Xiao Lin has been far ahead.
However, just 1000 meters from the end of the race, Xiao Lin suddenly felt pain in his waist. After he ran the full distance, Xiao Lin's back pain became even worse. When he went to the toilet, he found that his urine turned red.
Accompanied by his teacher, Xiao Lin went to the hospital for treatment. The doctor said that this was a typical manifestation of kidney injury.
The waist pain and hematuria of healthy people after strenuous exercise are obvious symptoms of kidney injury, which may be related to excessive exercise intensity and amount of exercise. There are many cases of exercise-induced kidney injury in clinic.
Seek medical attention in time for lumbago and hematuria after exercise
Experts pointed out that the kidney is deeply hidden on both sides of the lumbar spine and is well protected by the surrounding structures. However, the texture of the kidney itself is fragile, the envelope is thin, and there are bone structures around it. Therefore, the kidney is easily injured when it is impacted by violent force or external force.
Renal contusion is a common renal injury. "In this case, Guo's kidney was injured by severe vibration," the expert said. Not only that, the kidney will also be damaged when it is hit directly, such as falling into a hard object or being squeezed between two external violence.
The reason for Xiao Lin is that he exercises too much, lactic acid accumulates, muscle metabolic waste cannot be discharged in time, muscle cells are damaged, and a large amount of myoglobin is released into the blood, which will cause damage to the kidney if it exceeds the clearance capacity of the kidney.
Lumbar pain is one of the obvious symptoms of kidney injury. This pain is caused by local soft tissue injury or bone injury. Sometimes, renal colic can also be caused by obstruction of ureteral blood clots. When perirenal hematoma and urine extravasation form, local swelling will occur, which will form a mass in the abdomen, which is also one of the important symptoms of renal contusion. When the kidney is severely damaged, hematuria can be seen with the naked eye, while slight damage can be seen under the microscope.
Experts remind that after the above symptoms occur, you should go to the hospital in time. People with minor injuries can generally heal themselves. But if the injury is serious, serious renal laceration or other visceral injuries may occur, leading to shock, which requires surgical treatment, otherwise may endanger life.
In addition, severe exercise or sudden exercise after a long time of inactivity, such as marathon race, five-kilometer armed cross-country, rowing, mountaineering, weightlifting, and even physical punishment by teachers, may cause rhabdomyolysis, also known as athletic rhabdomyolysis.
Experts pointed out that rhabdomyolysis syndrome is not a simple disease, but a series of pathological changes. If you find yourself suffering from general discomfort, muscle pain and weakness, fever, tachycardia, nausea and vomiting after a sudden high-intensity exercise with little exercise for a long time, you should brace yourself and go to the hospital for medical examination, because dark urine is likely to contain excessive myoglobin.
After myolysis, myoglobin in muscle cells will flow into the blood and be discharged from the body through the kidney. Due to its large size, it will block the renal tubules and cause kidney damage. In addition, the damaged muscle cells will also secrete a large amount of potassium, which will cause hyperkalemia in the blood, and may cause cardiac arrest and endanger life in serious cases.
Although excessive exercise is very harmful, it is very common for accidental injury to cause tissue and viscera damage, pain and bleeding. Experts remind the general public not to be too panic. Blind fear and anxiety will prolong the treatment process. Patients should build up the confidence to overcome the disease and actively cooperate with the treatment.
After receiving timely treatment, the patient should rest in bed and determine the specific rest time under the guidance of the doctor; Drink more water to keep the urinary tract smooth; Eat more foods with high vitamins to provide rich nutrition for the recovery of the body, and avoid eating high-protein foods to avoid aggravating the burden on the kidney and stimulating foods. "We should also pay attention to the color and quantity of urine, whether there is swelling and pain in the kidney, and timely inform the doctor if any abnormality is found," the expert said. The family should replace the patient with an air cushion bed, which helps to clean and dry the skin and prevent pressure sores.
Because the kidney tissue is relatively fragile, premature activity will cause blood clots to fall off, resulting in secondary bleeding. Therefore, patients should avoid physical labor or exercise for at least 3 months after treatment. In the future, we should also pay attention to the changes of blood pressure and regularly check the renal function.
Exercise should be gradual
Exercise should be carried out step by step to avoid sudden increase in the amount and intensity of exercise. Proper exercise is more conducive to improving physical health and physical fitness. The American Association of Sports Medicine suggests that normal healthy adults should exercise 3 to 5 days a week, 30 to 60 minutes a day, and those who need to lose weight can appropriately extend the exercise time, 60 to 90 minutes a day.
The expert said: "People who have not exercised for a long time should not 'increase' their exercise. They should follow the principle of increasing the amount of exercise from small to large and from small to large. They can increase the amount of exercise by 5-10 minutes per week, and gradually increase the amount of exercise in at least 4 weeks until they reach the recommended standard value."
When running and jumping on hard ground such as cement ground, it is better to wear elastic shoes to reduce the shock of the body during exercise. Before a large amount of exercise, be sure to fully warm up and avoid long-term continuous training for a specific part. When exercising, pay attention to avoid taking exercise at noon in hot and humid summer in direct sunlight. Before, during and after training, enough water and electrolyte should be added to ensure the energy supply required by the body.
Although exercise is beneficial to human health, it is also necessary to pay attention to the combination of work and rest. Rest should be arranged before a large amount of exercise training. If the body is unwell, exercise and training should be canceled in time.
