Nantou Hospital pointed out that the woman surnamed Zhang, only 26 years old, usually works in Taipei. Because of her work, she had to sit at the computer desk for a long time. She wanted to increase the amount of exercise, so she signed up for a fitness class with her colleagues. She struggled for 1 hour after she came into contact with the flywheel bike. When she got off the bike, she suddenly felt weak in her legs. The next day, her muscles began to ache and her legs became swollen.
However, Zhang did not see a doctor immediately until she returned to her hometown in Nantou on holiday. When she went to the toilet, she was surprised to find that her urine was soy sauce-colored, thinking it was hematuria, and she was so scared that she hurried to see a doctor. Medical blood tests found that the CPK index was above 60,000, much higher than the normal value of 26- 140 IU/L, and it was diagnosed as rhabdomyolysis.
Zhuang Zongfang, medical secretary of Nantou Hospital and director of nephrology, said that rhabdomyolysis refers to the rapid injury of skeletal muscle, which leads to the necrosis of muscle cells and the destruction of cell membranes, resulting in a large amount of leakage of potassium ions, myoprotein, uric acid and other substances in cells, among which myoprotein will make urine appear soy sauce color, which is easy to be mistaken for hematuria because of its dark color.
The "soy sauce urine" caused by muscle protein means abnormal physical condition. If myoprotein blocks the renal tubule, the condition may be more serious, which may lead to acute renal failure and require renal dialysis treatment. Fortunately, the patient surnamed Zhang was found in time and was hospitalized urgently. It took 10 days for the index to decrease slowly, and the renal function was not affected. He is expected to leave the hospital this week.
Zhuang said that the symptoms of rhabdomyolysis usually appear when the muscles are seriously injured. If the patient is not squeezing muscles because of external pressure, but exercising, then it can be inferred that the patient should have no exercise habits and insufficient water supply. When they suddenly exert their strength and exercise excessively in a short time, rhabdomyolysis will occur.
Nantou Hospital therefore reminds that fitness is prevalent in recent years, and exercise is a good thing, but it is necessary to warm up before exercise, step by step, do what you can, and supplement appropriate water; After exercise, if you have symptoms such as muscle soreness, swelling and soy sauce color in your urine, you should seek medical advice as soon as possible.
