Kidney failure (renal failure) happens when your kidneys can no longer do their very important jobs. Kidneys function to filter waste, maintain electrolyte balance, regulate blood pressure and urine production. When kidney function stops, waste products accumulate in the body and can cause dangerous health complications.
There are two forms of renal failure:
Acute Renal Failure (ARF): This is a rapid deterioration in renal function, usually triggered by an inciting event like trauma or infection or as an adverse effect of the drug. With treatment, it can be reversible in some cases.
Chronic Kidney Disease (CKD): This is a long-term problem that develops slowly over time, usually years. CKD can progress to end-stage renal disease (ESRD) in which the function of the kidneys is very weak, and patients may require dialysis or a kidney transplant.
Symptoms of Renal Failure
During the initial stages renal failure may not give rise to any apparent symptoms. But they develop the signs as kidney function worsens, such as:
Tiredness: With the renal failure, it is common to have an increase in tiredness.
Swelling (Edema): Retaining fluid causes swelling of the ankles, legs, or face.
Reduced Urinary Output: A reduction in the amount of urine that is produced may signal kidney problems.
Difficulty breathing: Which is common in case there is excess fluid in lungs due to kidney failure or if anaemia sets in.
Confusion or Difficulty With Concentration: If there is a buildup of waste products in the blood (uremia) it can interfere with brain function.
Persistent nausea and vomiting: When there is a buildup of waste, this can make the body feel nauseous which is then followed by action to throw up.
Urinary changes: Blood in the urine, foamy urine, or darker it shows some kidney issue.
Kidneys & Hypertension: Damaged kidneys may no longer be able to control how much blood pressure is lowered, leading to hypertension.

Complications of renal failure can be potentially serious and, if not treated appropriately:
Hepatic Disease : The relationshipbetween kidneys and heart are very intimate. Anyone with kidney failure has a greater risk of heart disease, including heart attacks and heart failure.
Anemia: Normally, healthy kidneys produce a hormone called erythropoietin that helps the body make red blood cells. Reticulocytes – In renal failure, when erythropoietin production declines this causes anemia and fatigue.
Bone Disorder: The kidneys are responsible for managing calcium and phosphorus. This disease could disturb these minerals balance in the body and cause a brittle bones to break.
Fluid overload: Because the kidneys can’t filter well, fluids can accumulate in the body or create difficulty for breathing, high blood pressure, and swelling.
Electrolyte imbalance: The kidneys play a key role in the balance of important electrolytes such as potassium and sodium. This balance can get abnormal in kidney failure, causing excessive blood levels of these substances.
Uremia: a medical condition involving the build-up of wastes in the blood. If not treated, uremia is a serious condition that may cause confusion, itching, nausea and life-threatening complications.
Risk Factors For Kidney Failure
The risk of developing renal failure can be increased for various reasons, which are:
Diabetes: Elevated blood sugar levels can harm the kidney’s blood vessels, which can lead to diabetic nephropathy, a frequent cause of CKD.
High Blood Pressure (Hypertension) — High blood pressure can eventually damage your kidneys.
Heart disease: Because the heart and cardiovascular system are closely tied to the kidneys, those with heart disease are more likely to experience kidney issues.
Family History: A family history of kidney disease increases the risk of renal failure.
Age: With advancing age comes a natural decline in kidney function, and older adults are the population most at risk for renal failure.
Obesity: Overweight itself can be a risk factor for diabetes, high blood pressure which are the main risk factors of kidney disease.
Ongoing Infections: Recurrent kidney-related infections or UTIs may cause gradual harm to the kidneys.
Diagnosis of Renal Failure
Because of their symptoms and the underlying anatomic changes they would have encountered over several decades, for working out if someone had ended up experiencing renal failure physicians normally use a succession of tried and relatable specs.
Blood Tests — for testing levels of creatinine and blood urea nitrogen (BUN) to help examine kidney health. Increased values of these intermediates can point to impaired renal function.
Urine tests: A urine test may show abnormal amounts of protein, blood or other substances that can signal kidney problems.
Imaging Tests: These may include an ultrasound or CT scans of the kidneys to check for blockages, structural abnormalities, or other problems.
Kidney Biopsy — A kidney biopsy involves removing a small amount of kidney tissue in order to investigate the underlying cause of kidney failure.
Treatment of Renal Failure
Renal failure (whether it is acute or chronic, mild or severe) requires specific treatment. Key approaches include:
Treating Underlying Issues: The first line of treatment for renal failure is the management of any underlying issues, in particular diabetes or hypertension which may be responsible for damage to kidney function. You may be prescribed medications to reduce blood pressure, regulate blood sugar levels, or control cholesterol.
Dialysis — For patients with end-stage kidney failure, dialysis may be needed to do the filtering work of the kidneys. Dialysis is mainly of two types:
Hemodialysis: A machine filters the blood outside of the body before returning it to the bloodstream.
Peritoneal dialysis — A fluid is placed into the belly to help absorb waste products.
Kidney Transplant: If the kidneys no longer function well, patients may have to consider a kidney transplant. New kidneys are donated organs, surgically inserted in place of the damaged kidneys.
Medications: Different medications will be used to manage different symptoms of renal failure, including:
They then require diuretics, which help filter out excess fluid.
Erythropoiesis-stimulating agents (ESAs) for anemia treatment
Drugs to control the levels of calcium and phosphorus (phosphate binders).
Prevention of Renal Failure
Although you cannot prevent all cases of renal failure, there are steps you can take to reduce the risk:
Manage diabetes: If you have diabetes, controlling blood sugar is essential to prevent kidney damage.
Maintain Blood Pressure: Curse untimely men blood pressure. Maintaining a healthy lifestyle, with a balanced diet and regular physical activity as well reduction of salt can control hypertension.
Hydration: Keeping yourself hydrated with plenty of water aids kidney function and expels waste materials.
Caution with Painkillers: Nonsteroidal anti-inflammatory drugs (NSAIDs) and other over-the-counter pain relievers, can be harmful to the kidneys in high doses.
Routine check-ups : Routine blood and urine tests can determine early warning signs of kidney damage, if you have risk factors such as diabetes or high blood pressure.
Summary
If left untreated, renal failure can lead to a seire of complications. It happens after the kidneys are unable to filter out waste and also control functions such as blood pressure and balancing electrolytes among other things. Signs and symptoms include tiredness, leg swelling, feeling out of breath, and a change in urination. Answer: Treatment for kidney failure involves preventing further damage and improving kidney function; both are best achieved through early detection. There are situations where the things that lead to renal failure cannot be avoided but it is possible to reduce this risk by controlling blood sugar, controlling blood pressure and avoiding substances that damage kidneys.
