Exertional albuminuria refers to the phenomenon that urine protein increases when patients are exercising or after the exercise. The phenomenon makes many patients anvious, and dare not to take exercise.
As a matter of fact, many reports have shown that the positive rate from urine conventional examination is relatively higher after exercises such as track and field, swimming, playing football, and playing basketball. The amount of proteinuria is in proportion to the amount of exercise. Why does this phenomenon take place?
The pathogenesis of exertional albuminuria is unexplained now. At present, it is thought that exertional albuminuria is connected to trauma, stimulation from acid metabolin, ischemia caused by contraction of renal blood vessels, and the permeability change of glomerular basement membrane. A young man has no abnormal urine when he is quiet, but after movement, the protein appears in the urine, without any other specific symptoms or signs, and urine protein appears within 24 hours. This phenomenon maybe exertional albuminuria.
If a large quantity of proteinuria appears after a little exercise, the possibility of organic disease should not be considered.
Most exertional albuminuria is physiological urine, and doesn’t need treatment. People can get better after rest on the bed.
