An extreme consequence is the occurrence of the rare condition named calciphylaxis. Later, this progresses to secondary hyperparathyroidism, kidney osteodystrophy, and vascular calcification that further impairs cardiac function. Osteocytes are responsible for the increased production of FGF-23, which is a potent inhibitor of the enzyme 1-alpha-hydroxylase (responsible for the conversion of 25-hydroxycholecalciferol into 1,25 dihydroxyvitamin D 3).

Hypocalcemia results from 1,25 dihydroxyvitamin D 3 deficiency (caused by high FGF-23 and reduced kidney mass) and resistance to the action of parathyroid hormone.

Circulating concentrations of fibroblast growth factor-23 (FGF-23) increase progressively as the kidney capacity for phosphate excretion declines which may contribute to left ventricular hypertrophy and increased mortality in people with CKD. Hyperphosphatemia contributes to increased cardiovascular risk by causing vascular calcification.

Hyperphosphatemia results from poor phosphate elimination in the kidney.Fluid overload symptoms may range from mild edema to life-threatening pulmonary edema.Hyperkalemia in CKD can be exacerbated by acidemia (which leads to extracellular shift of potassium) and from lack of insulin. Hyperkalemia usually does not develop until the glomerular filtration rate falls to less than 20–25 ml/min/1.73 m 2, at which point the kidneys have decreased ability to excrete potassium. Potassium accumulates in the blood ( hyperkalemia with a range of symptoms including malaise and potentially fatal cardiac arrhythmias).

Due to its high systemic concentration, urea is excreted in eccrine sweat at high concentrations and crystallizes on skin as the sweat evaporates (' uremic frost').

Urea accumulates, leading to azotemia and ultimately uremia (symptoms ranging from lethargy to pericarditis and encephalopathy).

Blood pressure is increased due to fluid overload and production of vasoactive hormones created by the kidney via the renin–angiotensin system, increasing the risk of developing hypertension and heart failure.

As the kidney function decreases, more unpleasant symptoms may emerge: ĬKD is initially without symptoms, and is usually detected on routine screening blood work by either an increase in serum creatinine, or protein in the urine. The causes that contribute to the greatest number of deaths are high blood pressure at 550,000, followed by diabetes at 418,000, and glomerulonephritis at 238,000. Ĭhronic kidney disease affected 753 million people globally in 2016: 417 million females and 336 million males. Severe disease requires hemodialysis, peritoneal dialysis, or a kidney transplant for survival. Treatments for anemia and bone disease may also be required. Other recommended measures include staying active, and certain dietary changes such as a low-salt diet and the right amount of protein.

Loop diuretics may be used to control edema and, if needed, to further lower blood pressure. Angiotensin converting enzyme inhibitors (ACEIs) or angiotensin II receptor antagonists (ARBs) are generally first-line agents for blood pressure control, as they slow progression of the kidney disease and the risk of heart disease. Initial treatments may include medications to lower blood pressure, blood sugar, and cholesterol. Several severity-based staging systems are in use. Ultrasound or kidney biopsy may be performed to determine the underlying cause. Diagnosis is by blood tests to measure the estimated glomerular filtration rate (eGFR), and a urine test to measure albumin. Risk factors include a family history of chronic kidney disease. Ĭauses of chronic kidney disease include diabetes, high blood pressure, glomerulonephritis, and polycystic kidney disease. Complications include an increased risk of heart disease, high blood pressure, bone disease, and anemia. Initially there are generally no symptoms later, symptoms may include leg swelling, feeling tired, vomiting, loss of appetite, and confusion. Chronic kidney disease ( CKD) is a type of kidney disease in which there is gradual loss of kidney function over a period of months to years.
