Acute Kidney Failure – What is it, Causes and Treatments!

Acute Kidney Failure – What it is, Causes and Treatments of this condition. Also, Acute Kidney Failure (ARF), formerly called acute kidney injury (AKI), is an abrupt loss of kidney function that develops within 7 days. Its causes are numerous.

It usually occurs because of damage to kidney tissue caused by decreased renal blood flow (kidney ischemia) from any cause (e.g. low blood pressure), exposure to substances harmful to the kidney, an inflammatory process in the kidney , or a urinary tract obstruction that prevents the flow of urine .

Acute Kidney Failure is diagnosed based on characteristic laboratory findings, such as elevated blood urea nitrogen and creatinine, or an inability of the kidneys  to produce sufficient amounts of urine .

Acute Kidney Failure can lead to a number of complications, including metabolic acidosis, high potassium levels, uremia, changes in body fluid balance, and effects on other organ systems, including death.

People who have experienced Acute Kidney Failure may have an increased risk of chronic kidney disease in the future. Management includes treating the underlying cause and supportive care such as renal replacement therapy. So, check out now  Acute Kidney Failure – What is it, Causes and Treatments:

What is Acute Kidney Failure:  Acute  Kidney Failure occurs when your kidneys  are suddenly unable to filter waste products from your blood. When your kidneys lose their filtering ability, dangerous levels of waste can build up and your blood’s chemical makeup can go out of balance.

Acute Kidney Failure – also called Acute Kidney Failure or Acute Kidney Injury – develops rapidly over a few hours to a few days.

Acute Kidney Failure is more common in people who are already hospitalized, particularly in critically ill people who need intensive care. Acute Kidney Failure can be fatal and requires intensive treatment.

However, Acute Kidney Failure can be reversible. If you are in good health, you can regain normal or near-normal kidney function.

Causes of Acute Kidney Failure:  Acute Kidney Failure can occur when:

  • You have a condition that slows blood flow to your kidneys
  • You suffer direct damage to your kidneys
  • The kidneys  ‘ urine drainage tubes  (ureters) become blocked and waste cannot leave your body through your urine

Symptoms of Acute Kidney Failure:  Signs and symptoms of  Acute Kidney Failure can include:

  • Decreased urine output , although occasionally urine output  remains normal
  • Fluid retention, causing swelling in the legs, ankles, or feet
  • Somnolence
  • Shortness of breathe
  • Fatigue
  • Confusion
  • Nausea
  • Seizures or coma in severe cases
  • Chest pain or pressure

Sometimes Acute Kidney Failure causes no signs or symptoms and is detected through laboratory tests done for another reason. Make an appointment with your doctor if you have any signs or symptoms of Acute Kidney Failure .

Acute Kidney Failure Risk Factors:  Acute Kidney Failure almost always occurs in connection with another medical condition or event. Conditions that can increase your risk of Acute Kidney Failure include:

  • Being hospitalized, especially for a serious condition that requires intensive care
  • Advanced age
  • Blockages in blood vessels in the arms or legs (peripheral artery disease)
  • Diabetes
  • High pressure
  • Cardiac insufficiency
  • kidney diseases
  • liver diseases

Complications of Acute Kidney Failure:  Possible complications of Acute Kidney Failure include:

  • Fluid accumulation. Acute Kidney Failure can lead to a buildup of fluid in your lungs, which can cause shortness of breath.
  • Chest pain. If the lining that covers your heart (pericardium) becomes inflamed, you may experience chest pain.
  • Muscle weakness. When your body’s fluids and electrolytes – your body’s blood chemistry – are out of balance, muscle weakness can result. High levels of potassium in your blood are particularly dangerous.
  • Permanent kidney damage. Occasionally, Acute Kidney Failure causes permanent loss of kidney function or end-stage renal disease. People with end-stage kidney disease require permanent dialysis – a mechanical filtration process used to remove toxins and waste from the body – or a kidney transplant to survive.
  • Death. Acute Kidney Failure can lead to loss of kidney function and, ultimately, death. The risk of death is higher in people who had kidney problems before acute kidney failure .

Diagnosis of Acute Kidney Failure:  If your signs and symptoms suggest you have Acute Kidney Failure , your doctor may recommend certain tests and procedures to verify your diagnosis. These may include:

  • Urine output measurements. The amount of urine  you excrete in a day can help your doctor determine the cause of your Acute Kidney Failure  .
  • Urine tests . Analyzing a sample of your urine , a procedure called a urinalysis , can reveal abnormalities that suggest Acute Kidney Failure.
  • Bloodtests. A sample of your blood can reveal rapidly rising levels of urea and creatinine – two substances used to measure kidney function.
  • Image tests. Imaging tests, such as an ultrasound and CT scan, can be used to help your doctor see your kidneys .
  • Removing a kidney tissue sample for testing. In some situations, your doctor may recommend a kidney biopsy to remove a small sample of kidney tissue for lab tests. Your doctor inserts a needle into your skin and kidney to remove the sample.

Treatments for Acute Kidney Failure:  Treatment for Acute Kidney Failure usually requires a hospital stay. Most people with Acute Kidney Failure are already hospitalized. How long you will stay in the hospital depends on the reason for your Acute Kidney Failure and how quickly your kidneys  recover. In some cases, you can recover at home.

Treating the underlying cause of your kidney failure:  Treatment for Acute Kidney Failure involves identifying the disease or injury that originally damaged your kidneys . Your treatment options depend on what is causing your Acute Kidney Failure .

Treat complications until your kidneys recover: Your doctor will also work to prevent complications and allow your kidneys time  to heal. Treatments that help prevent complications include:

  • Treatments to balance the amount of fluid in your blood. If your Acute Kidney Failure is caused by a lack of fluid in your blood, your doctor may recommend intravenous (IV) fluids. In other cases, Acute Kidney Failure can cause excess fluid, leading to swelling in the arms and legs. In these cases, your doctor may recommend medication (diuretics) to cause your body to expel additional fluid.
  • Medicines to control potassium in the blood. If your kidneys  aren’t properly filtering potassium in your blood, your doctor may prescribe sodium sulfate, calcium, glucose, or sodium (Kayexalate, Kionex) to prevent the buildup of high levels of potassium in your blood. Too much potassium in the blood can cause dangerous irregular heartbeats (arrhythmias) and muscle weakness.
  • Medicines to restore blood calcium levels. If blood calcium levels drop too low, your doctor may recommend a calcium infusion.
  • Dialysis to remove toxins from your blood. If toxins build up in your blood, you may need temporary hemodialysis – often referred to simply as dialysis – to help remove toxins and excess fluid from your body while your kidneys  heal. Dialysis can also help remove excess potassium from your body. During dialysis, a machine pumps blood out of your body through an artificial kidney (dialysis) that filters waste. The blood is then returned to your body.

Preventing Acute Kidney Failure:  Acute Kidney Failure is often difficult to predict or prevent. But you can reduce your risk by taking care of your kidneys . Try:

  • Pay attention to labels when taking over-the-counter (OTC) pain medications. Follow directions for OTC pain medications such as aspirin, acetaminophen (Tylenol, others), and ibuprofen (Advil, Motrin IB, others). Taking too many medications can increase your risk of Acute Kidney Failure . This is especially true if you have pre-existing kidney disease, diabetes , or high blood pressure.
  • Work with your doctor to manage kidney problems. If you have kidney disease or another condition that increases your risk of Acute Kidney Failure , such as diabetes or  high blood pressure , stay on track with treatment goals and follow your doctor’s recommendations for managing your condition.
  • Make a healthy lifestyle a priority. Be active; Eat a sensible and balanced diet; And drink alcohol only in moderation – if at all.
