Here's a comprehensive overview of kidney failure:

*Definition:* Kidney failure, also known as renal failure, occurs when the kidneys lose their ability to filter waste and excess fluids from the blood.

*Types:*

1. Acute kidney injury (AKI): sudden loss of kidney function
2. Chronic kidney disease (CKD): gradual loss of kidney function over time
3. End-stage renal disease (ESRD): severe kidney damage requiring dialysis or transplant

*Causes:*

1. Diabetes
2. High blood pressure
3. Kidney inflammation (nephritis)
4. Kidney damage (nephrosis)
5. Inherited disorders (e.g., polycystic kidney disease)
6. Medications (e.g., NSAIDs)
7. Toxins (e.g., heavy metals)

*Symptoms:*

1. Fatigue
2. Swelling (edema)
3. Nausea and vomiting
4. Abnormal urine output
5. Pale or itchy skin
6. Muscle cramps
7. Breathlessness

*Treatment:*

1. Dialysis (hemodialysis or peritoneal dialysis)
2. Kidney transplant
3. Medications (e.g., ACE inhibitors, beta-blockers)
4. Lifestyle changes (e.g., diet, exercise, stress reduction)



*Prevention:*

1. Manage underlying conditions (diabetes, hypertension)
2. Maintain a healthy weight
3. Exercise regularly
4. Avoid harmful substances (e.g., tobacco, heavy metals)
5. Stay hydrated

*Diet for Kidney Failure:*

1. Low-protein diet
2. Low-sodium diet
3. Low-potassium diet
4. Avoid phosphorus-rich foods
5. Stay hydrated

*Complications:*

1. Anemia
2. Bone disease
3. Cardiovascular disease
4. Fluid overload
5. Electrolyte imbalance

*Prognosis:*

Depends on the underlying cause and severity of kidney failure. With proper treatment, many patients with kidney failure can lead active and productive lives.
