In particular, if you are suffering from high blood pressure or diabetes, the longer the prevalence period, the more complications in the kidneys can progress, so it is important to check for proteinuria through regular urine tests.
Proteinuria is often found accidentally in most medical examinations. Symptoms that patients can experience related to proteinuria, such as when the foam does not disappear and most of the urine remains more than 10 minutes after urination, and when swelling is accompanied on the face and eyelids after waking up or when the ankle is swollen in the afternoon after activities. However, since it is difficult to conclude that proteinuria exists only with these symptoms, it is essential to be diagnosed through accurate examination.
Proteinuria is usually diagnosed when the total output of protein in the entire urine of the day is more than 150 mg. An easy way to check the presence or absence of proteinuria is the Dipstick method, but the accuracy is low due to high false positives. Therefore, for accurate diagnosis, ▲ urinary protein/creatinine ratio (UPCR) ▲ 24-hour urine protein quantification test should be performed.
Proteinuria is an important sign of chronic kidney disease and an important prognostic factor for cardiovascular disease, so early detection and management are important. In particular, patients with chronic diseases such as high blood pressure and diabetes have a higher risk of proteinuria as the prevalence period increases, so regular checkups are required along with proper blood pressure and blood sugar management, and the following lifestyle correction should be performed for prevention and management.
First of all, it is recommended to manage blood pressure and blood sugar at an appropriate level, to combine a low-salt diet, and to avoid excessive intake of protein if proteinuria is already accompanied. It is helpful to maintain a proper weight, drink enough water, and do steady aerobic exercise. At the same time, it is advisable to quit smoking and refrain from drinking too much.
Professor Ahn Shin-young of the Department of Nephrology at Guro Hospital of Korea University said, `Proteinuria is not only an important sign of kidney damage, but also an important sign that complications of chronic diseases such as diabetes and high blood pressure have progressed, and furthermore, since asymptomatic proteinuria is an important prognostic factor for cardiovascular disease, proper dietary control, lifestyle improvement, and drug treatment can slow disease progression and improve prognosis.' Therefore, when proteinuria is suspected, it is necessary to actively test and respond without inadvertently overlooking it.
