Any type of kidney disease that lasts longer than three months and impairs kidney function.

Functional anomaly of the kidney persisting for at least three months.

Impairment of the renal function secondary to chronic kidney damage persisting for three or more months.

You have two kidneys, each about the size of your fist. Their main job is to filter your blood. They remove wastes and extra water, which become urine. They also keep the body's chemicals balanced, help control blood pressure, and make hormones. Chronic kidney disease (CKD) means that your kidneys are damaged and can't filter blood as they should. This damage can cause wastes to build up in your body. It can also cause other problems that can harm your health. Diabetes and high blood pressure are the most common causes of CKD. The kidney damage occurs slowly over many years. Many people don't have any symptoms until their kidney disease is very advanced. Blood and urine tests are the only way to know if you have kidney disease. Treatments cannot cure kidney disease, but they may slow kidney disease. They include medicines to lower blood pressure, control blood sugar, and lower cholesterol. CKD may still get worse over time. Sometimes it can lead to kidney failure. If your kidneys fail, you will need dialysis or a kidney transplantation. You can take steps to keep your kidneys healthier longer: Choose foods with less salt (sodium); Control your blood pressure; your health care provider can tell you what your blood pressure should be; Keep your blood sugar in the target range, if you have diabetes; Limit the amount of alcohol you drink; Choose foods that are healthy for your heart: fruits, vegetables, whole grains, and low-fat dairy foods; Lose weight if you are overweight; Be physically active; Don't smoke.

A disorder characterized by gradual and usually permanent loss of kidney function resulting in renal failure.

Chronic kidney disease (CKD) is long-standing, progressive deterioration of renal function. Symptoms develop slowly and in advanced stages include anorexia, nausea, vomiting, stomatitis, dysgeusia, nocturia, lassitude, fatigue, pruritus, decreased mental acuity, muscle twitches and cramps, water retention, undernutrition, peripheral...

Chronic kidney disease (CKD)�or chronic renal failure (CRF), as it was historically termed�is a term that encompasses all degrees of decreased renal function, from damaged�at risk through mild, moderate, and severe chronic kidney failure. CKD is a worldwide public health problem.

Chronic kidney disease, also called chronic kidney failure, describes the gradual loss of kidney function. Your kidneys filter wastes and excess fluids from your blood, which are then excreted in your urine. When chronic kidney disease reaches an advanced stage, dangerous levels of fluid, electrolytes and wastes can build up in your body.

Chronic kidney disease, also known as chronic renal failure, is defined by either a pathologic abnormality of the kidney, such as hematuria and/or proteinuria, or a reduction in the GFR to <60 mL/minute/1.73 m^2 for ?3 months' duration.
