Global Facts: About kidney Disease

Kidney disease is a significant worldwide public health problem. Acute kidney injury (AKI) and chronic kidney disease (CKD) are linked to high health care costs, poor quality of life, and serious adverse health outcomes. 10% of the population worldwide is affected by chronic kidney disease (CKD), and millions die each year because they do not have access to affordable treatment. Over 2 million people worldwide currently receive treatment with dialysis or a kidney transplant to stay alive, yet this number may only represent 10% of people who actually need treatment to live. In people aged 65 through 74 worldwide, it is estimated that one in five men, and one in four women, have CKD. Noncommunicable diseases (such as heart disease, diabetes, or kidney disease) have replaced communicable diseases (such as influence, malaria, or AIDs) as the most common causes of premature death worldwide. An estimated 80% of this burden occurs in low- or middle-income countries, and 25% is in people younger than 60 years.

The most common kinds of kidney disease

  • Chronic kidney disease: A major cause of chronic kidney disease is high blood pressure. Because your kidneys are constantly processing your body's blood, they touch 20 percent of your total blood every minute. High blood pressure is dangerous for your kidneys because it can lead to increased pressure on the glomerulus, which is your functional unit. Over time, this high pressure can damage your kidney's filtration unit and its function will decline.
  • Kidney stones: Minerals and other substances in your blood may crystallize in your kidneys, forming solid particles, or stones, that are usually excreted in your urine. Excreted kidney stones can be very painful, but they rarely cause major problems.
  • Glomerulonephritis: Glomerulonephritis (gloe-MER-u-loe-nuh-FRY-tis) is kind of kidney disease of the tiny filters in the kidneys (glomeruli). The excess fluid and waste that glomeruli (gloe-MER-u-lie) remove from the bloodstream exit the body as urine. Glomerulonephritis can come on suddenly (acute) or gradually (chronic).
  • Polycystic kidney disease: Polycystic kinds of kidney disease can also cause cysts to develop in your liver and elsewhere in your body. The disease can cause serious complications, including high blood pressure and kidney failure.

Why is it important to check kidney function

How well your kidneys work is called kidney function. Your kidneys have the important job of filtering your blood. They remove waste products and extra fluid from your body. When your kidneys do not work as they should, waste can build up in your blood. This can make you sick. If you have long-term (chronic) kidney disease, you may not have any symptoms until your kidney function is very low. Blood and urine tests can help show how well your kidneys are working. They can help your doctor know better of your body .

Kidney function goals

1.Uric Acid Test Normal Results
Most adults lose between 500 and 600 milligrams of uric acid in their pee every 24 hours. More than 800 milligrams is too much if you ’re eating a regular diet.

2.Creatinine Test Normal Results
Creatinine usually enters your bloodstream and is filtered from the bloodstream at a generally constant rate. The amount of creatinine in your blood should be relatively stable. An increased level of creatinine may be a sign of poor kidney function.
Serum creatinine is reported as milligrams of creatinine to a deciliter of blood (mg/dL) or micromoles of creatinine to a liter of blood (micromoles/L). The typical range for serum creatinine is: For adult men, 0.74 to 1.35 mg/dL (65.4 to 119.3 micromoles/L) For adult women, 0.59 to 1.04 mg/dL (52.2 to 91.9 micromoles/L).

3.Urea Test Normal Results
Normal values range from 12 to 20 grams per 24 hours (428.4 to 714 mmol/day). Normal value ranges may vary slightly among different laboratories. Some labs use different measurements or test different samples. Talk to your provider about the meaning of your specific test results.

How frequently do you need to measure eGFR?

  • annually in all at risk groups
  • during intercurrent illness and perioperatively in all patients with CKD. Exact frequency should depend on the clinical situation. The frequency of testing may be reduced where eGFR levels remain very stable but will need to be increased if there is rapid progression
StageeGFR range(ml/min/1.73m ^22)Typical frequency of testing
1 and 2>60+other evidence of kidney disease12 monthly
3A and 3B30-596 monthly
