Severe exercise leads to renal contusion.
Guo, a 20-year-old classmate, likes sports very much on weekdays. Every day after dinner, he goes downstairs to the residents' fitness center. He went to the horizontal bar to do pull-ups the day before yesterday. After doing it a few times, Guo felt his arm twitched and suddenly lost his strength. Guo involuntarily loosened the horizontal bar and people fell heavily to the ground.
An unbearable pain in the waist hit Guo, and his neighbors took him to the hospital. After examination, Guo was diagnosed as "right kidney contusion".
/kloc-Kobayashi, a 0/6-year-old senior three student, has a similar situation. Xiao Lin is a special student in sports, and participates in the long-distance running competition held by the school every year. This year, Kobayashi signed up for the self-confidence project of the 333545000-meter long-distance race. Kobayashi was far ahead from the beginning.
However, just before the finish line 1000m, Kobayashi suddenly felt a pain in his waist. After enduring the discomfort of running all the way, Kobayashi's back pain intensified. When he went to the toilet, he found that his urine turned red.
Accompanied by the teacher, Xiao Lin went to the hospital. The doctor said it was a typical kidney injury.
Healthy people have low back pain, hematuria and so on. After strenuous exercise, this is an obvious symptom of kidney injury, which is probably related to excessive exercise intensity and exercise. There are many cases of exercise-related kidney injury in clinic.
Back pain and hematuria after exercise should attract medical attention.
Experts pointed out that the kidney is deeply hidden in the waist and spine of the human body and is well protected by the surrounding structures. However, the kidney itself is fragile, with a thin capsule and a bone structure surrounding it. Therefore, when the kidney is hit by violence or external force, it is easy to get hurt.
Renal contusion is a common renal injury. "This situation of Guo's classmates is because the kidneys are violently vibrating and hurting the kidneys." Experts said. Not only that, the kidney will also be damaged when it is directly hit, such as falling on a hard object or being squeezed between two external violence.
Kobayashi's condition is due to his excessive exercise, lactic acid accumulation, inability to excrete muscle metabolic waste in time, muscle cell damage, and a large amount of myoglobin released into the blood, which will cause damage to the kidney if it exceeds the clearance capacity of the kidney.
Low back pain is one of the obvious symptoms of kidney injury, which is caused by local soft tissue injury or bone injury. Sometimes, renal colic can be caused by obstruction of ureteral blood clot. When perirenal hematoma and urine extravasation form, local swelling will occur, thus forming a mass in the abdomen, which is also one of the important symptoms of renal contusion. Hematuria can be seen with the naked eye when the kidney is seriously damaged, and only under the microscope when the kidney is slightly damaged.
Experts remind that you should seek medical advice promptly after the above symptoms appear. Minor injuries can generally heal themselves, but if the injury is serious, severe renal laceration or other organ damage may occur, leading to shock, and surgery must be performed, otherwise it may be life-threatening.
In addition, strenuous exercise or sudden exercise after a long period of inactivity, such as marathon, five-kilometer armed cross-country, boating, mountain climbing, weightlifting, and even teachers' corporal punishment of students, may lead to rhabdomyolysis, also known as sports rhabdomyolysis.
Experts pointed out that rhabdomyolysis syndrome is not a simple disease, but a series of pathological changes. If you find yourself unwell, muscle aches and weakness, fever, tachycardia, nausea and vomiting. Cheer up after a sudden high-intensity exercise with little exercise for a long time. You'd better go to the hospital for physical examination, because dark urine probably means too much myoglobin in your urine.
After muscle dissolution, myoglobin in muscle cells will flow into the blood and be excreted through the kidney. Because it is too big to be discharged smoothly, it will block the renal tubules and cause kidney damage. Moreover, damaged muscle cells will secrete a lot of potassium, which will cause hyperkalemia when it enters the blood. In severe cases, it can lead to cardiac arrest and endanger life.
Although excessive exercise is very harmful, it is very common for accidental injuries to cause tissue and organ damage, pain and bleeding. Experts remind the general public not to be too alarmed. Blind fear and anxiety will prolong the treatment process. Patients should establish confidence in overcoming the disease and actively cooperate with the treatment.
After receiving timely treatment, patients should stay in bed and determine the specific rest time under the guidance of doctors; Drink plenty of water to keep the urinary tract unobstructed; Eat more foods with high vitamin content, provide rich nutrition for the recovery of the body, and avoid eating high-protein foods, so as not to increase the burden on the kidneys and avoid irritating foods. "You should always pay attention to the color and quantity of urine, whether there is pain in the kidneys, and notify the doctor in time if you find any abnormality." Experts said. It's best for family members to replace the patient with a air mattress, which will help clean dry skin and prevent pressure sores.
Because the kidney tissue is fragile, premature activity will cause blood clots to fall off and cause secondary bleeding. Therefore, patients should avoid physical labor or exercise for at least 3 months after being cured. In the future, we should always pay attention to the changes of blood pressure and check the renal function regularly.
Exercise should be gradual.
Exercise should be done step by step to avoid a sudden increase in the amount and intensity of exercise. Proper exercise is more conducive to improving physical health and physique. The American Sports Medicine Association recommends that normal and healthy adults exercise for 30 to 60 minutes a day, 3 to 5 days a week, and those who need to lose weight can appropriately extend the exercise time for 60 to 90 minutes a day.
Experts said, "People who don't exercise for a long time especially don't exercise' overweight'. 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 for at least 4 weeks until they reach the recommended standard value. "
When running and jumping in hard places such as concrete, it is best to wear elastic shoes to reduce physical impact during exercise. Before doing a lot of exercise, you must fully warm up and avoid long-term continuous training for a specific part. When exercising, be careful not to do it in direct sunlight at noon in hot and humid summer. Enough water and electrolyte should be added before, during and after training to ensure the energy supply needed by the body.
Although exercise is beneficial to human health, we should pay attention to the combination of work and rest. Rest should be arranged before a lot of exercise training. If you feel unwell, you should cancel exercise and training in time.
