Learn about chronic kidney disease (CKD), a condition where the kidneys sustain long-term damage and lose their ability to function properly, including its stages, causes, symptoms, diagnosis, prevention and management, and how to protect your kidney health.
Chronic kidney disease (CKD) is a condition where the kidneys sustain long-term damage and lose their ability to function properly. CKD leads to a decline in the kidneys' ability to filter waste and excess fluids from the blood. In this comprehensive guide, we`ll learn everything we need to know about CKD including the various types of CKD, causes, symptoms, pathophysiology, treatment options, complication, preventions and nursing care
Chronic kidney disease (CKD), also referred to as chronic renal disease, is a condition where the kidneys sustain long-term damage and lose their ability to function properly. The kidneys play a crucial role in filtering waste, toxins, and excess fluids from the blood, while also contributing to red blood cell production and bone health. As CKD progresses, waste accumulates in the bloodstream, leading to various complications.
CKD is termed "chronic" because kidney function declines gradually over time. While some individuals with CKD may not develop kidney failure, untreated CKD can lead to end-stage kidney disease (ESKD), requiring dialysis or a kidney transplant for survival.
CKD is characterized by structural changes in the kidneys, including damage to blood vessels and nephrons, and is defined by an estimated glomerular filtration rate (eGFR) of less than 60 mL/min/1.73 m² persisting for three months or more. The disease progresses through five stages, with worsening kidney function over time. Most cases of CKD are mild or moderate (stages 1-3).
Although there is no cure for CKD, early detection and management can slow its progression. Lifestyle modifications, medication, and dietary changes are essential in preserving kidney function and preventing complications.
Chronic kidney disease (CKD) affects approximately 1 in 10 people, indicating that it is a common health issue. CKD can develop at any age, and various underlying conditions may lead to its onset. The incidence of CKD increases with age and is generally more prevalent in women. Notably, around half of individuals aged 75 or older have some degree of chronic kidney disease.
Anyone can get chronic kidney disease. However, individual at more risk for chronic kidney disease are;
Chronic kidney disease (CKD) is caused by long-term damage to the kidneys, leading to a gradual loss of function. Several conditions contribute to CKD development. Common Causes of CKD:
Chronic kidney disease (CKD) is classified into five stages based on kidney function and the ability to filter waste from the blood. The stages are determined by blood and urine tests that measure the glomerular filtration rate (GFR), which indicates how well the kidneys are functioning. The stages range from very mild (stage 1) to kidney failure (stage 5).
| Stage | eGFR (mL/min/1.73 m2) | Level of damage | Symptoms |
|---|---|---|---|
| 1 | 90 and above | Mild | Typically asymptomatic |
| 2 | 60–89 | Mild | Typically asymptomatic |
| 3a | 45–59 | Mild to moderate | Weakness or fatigue |
| 3b | 30–44 | Moderate to severe | Kidney pain, Foamy urine, Muscle cramps, Itching, Swelling of hands or feet, restless leg, problem sleeping |
| 4 | 15–29 | Severe | Headache, Urinating more or less than usual, Loss of appetite, hematuria, Inability to concentrate Swelling around eyes and ankles, Easy bruising |
| 5 | below 15 | Failure or near-failure | Little or no urination, Shortness of breath, Chest pain, Nausea or vomiting, Bone pain, Weight loss, Skin and nail changes, Irregular heartbeats |
Chronic kidney disease (CKD) involves the gradual and irreversible loss of kidney function due to sustained structural damage. Unlike acute kidney injury (AKI), which may recover, CKD leads to persistent fibrosis and deterioration of kidney structure, affecting the glomeruli, tubules, interstitium, and blood vessels. These changes impair glomerular filtration, leading to proteinuria. Blood vessels narrowing and hardening limit oxygen and nutrient delivery resulting in apoptosis and necrosis, further progressing kidney tissue loss and functional decline. These processes, if left untreated, eventually leads to end-stage renal disease.
Early CKD stages are asymptomatic, and Symptoms tend to develop when chronic kidney disease becomes severe, thus, in stages 4 or 5. Some common symptoms and signs at these stages of CKD include:
Chronic kidney disease (CKD) is diagnosed through a combination of blood tests, urine tests, imaging studies, and, in some cases, a kidney biopsy.
The management of chronic kidney disease (CKD) focuses on slowing disease progression, treating underlying causes, and addressing complications. While there is no cure for CKD, effective treatment can help preserve kidney function and improve quality of life.
In severe cases, advanced treatment options include;
For individuals who progress to end-stage renal disease (ESRD), dialysis may be necessary to remove waste from the body. There are two primary types of dialysis:
Blood is filtered through a machine that removes waste, products, excess water and excess salt and then returned back to the body. It is typically performed three times a week for four hours.
A dialysis solution is infused into the abdomen to absorb waste through a catheter. The solution absorbed waste is then removed via the same catheter. Fresh solution is added to continue the process of cleaning. This process can be done at home, with options for manual or machine-assisted processes. There are two types of peritoneal dialysis which are; continuous ambulatory peritoneal dialysis (CAPD) and continuous cycling peritoneal dialysis (CCPD). CAPD involves a change in dialysis solution four times a day while CCPD uses a machine to automatically fill, remove and refill the fluid during the nighttime.
Lifestyle changes are crucial at every stage of chronic kidney disease (CKD) to promote health and slow disease progression. Recommended modifications include:
These measures are crucial for the optimal care of individuals with CKD
Observation
Nutrition
Personal hygiene
Patient education
Psychological care
Rest and Exercise
