Chronic kidney disease (CKD) is a type of kidney disease in which a gradual loss of kidney function occurs over a period of months to years. Initially generally no symptoms are seen, but later symptoms may include leg swelling, feeling tired, vomiting, loss of appetite, and confusion. Complications can relate to hormonal dysfunction of the kidneys and include (in chronological order) high blood pressure (often related to activation of the renin–angiotensin system), bone disease, and anemia. Additionally CKD patients have markedly increased cardiovascular complications with increased risks of death and hospitalization.Causes of chronic kidney disease include diabetes, high blood pressure, glomerulonephritis, and polycystic kidney disease. Risk factors include a family history of chronic kidney disease. Diagnosis is by blood tests to measure the estimated glomerular filtration rate (eGFR), and a urine test to measure albumin. Ultrasound or kidney biopsy may be performed to determine the stage of kidney disease

Study Notes
Hyperkalemia
- Normal potassium levels range from 3.5 to 5.0 mmol/L; levels above 5.5 mmol/L indicate hyperkalemia.
- Hyperkalemia does not typically cause symptoms in the early stages.
- Severity classifications: mild (5.5–5.9 mmol/L), moderate (6.0–6.4 mmol/L), and severe (>6.5 mmol/L).
- Electrocardiograms (ECGs) can detect high potassium levels.
- Common causes include kidney failure, hypoaldosteronism, and other medical conditions.
- Initial treatment for hyperkalemia with ECG changes often involves potassium-binding salts.
Chronic Kidney Disease (CKD)
- CKD is characterized by gradual kidney function loss occurring over months to years.
- Early stages generally show no symptoms; symptoms may later include leg swelling, fatigue, vomiting, loss of appetite, and confusion.
- Complications can include hormonal dysfunction affecting blood pressure, bone health, and anemia.
- CKD significantly increases the risk of cardiovascular complications, leading to higher mortality and hospitalization rates.
Causes and Risk Factors of CKD
- Common causes include diabetes, high blood pressure, glomerulonephritis, and polycystic kidney disease.
- Family history of CKD is a notable risk factor.
Diagnosis of CKD
- Diagnosis involves blood tests to evaluate the estimated glomerular filtration rate (eGFR) and urine tests to assess albumin levels.
- Imaging methods like ultrasound or kidney biopsy may be used to determine the stage and cause of kidney disease.
