24-Hour Urinary Sodium Test Predicts Progression of Kidney DiseaseWhich indicators should be used to assess the risk of kidney disease progression?

Urinary protein, which most kidney patients think of first, is also the most familiar test. Blood pressure, blood sugar, occult blood and so on will also be concerned. However, few patients are concerned about the 24-hour urinary sodium test, which affects the progression of kidney disease.

24-hour urinary sodium determination refers to the examination of 24-hour urinary sodium ion concentration, indicating the amount of urinary sodium. The normal value is less than 100 mmol. Studies have shown that Kidney Failure accelerates with the increase of sodium excretion in urine. When 24h urinary sodium exceeds 100 mmol, there is a marked increase in mortality and risk of disease progression.

Why is urine high in sodium?

Sodium is from what we eat.

The salt we usually eat is sodium chloride, which dissolves into chloride and sodium ions after entering the human body. Excessive concentration of sodium ions will raise blood pressure, induce edema and damage the kidney. A small amount of sodium in the human body comes from the sodium originally contained in daily food, most of which comes from salt.

Many people do not know that they eat too much salt, and think that they eat very light. Especially for the elderly, their taste bud degenerates, so they often cook with a lot of salt. Maybe they usually think they are on a low-salt diet, but when they test sodium in urine, they find that the salt level is several times higher than the standard.

Eating less salt 1 g a day can reduce blood pressure by at least 1 mmHg. The average daily salt intake of Chinese residents is 12 g. If the daily salt intake is 3-6 g according to the low-salt diet of kidney patients, which is also required by the dietary guidelines of Chinese residents, the blood pressure can be reduced by 6-9 mmHg. People in northern China eat more salt, an average of 18 g a day. Low-salt diet can lower blood pressure more effectively.

To lower blood pressure is the precondition of treating kidney disease and reducing urinary protein. Blood pressure is also often related to the final outcome and life span of patients with kidney disease.

Take a look at your 24-hour sodium urine and let a low-salt diet help you prevent kidney disease from progressing. For more information on kidney disease treatment, please leave a message below or contact online doctor.
