What are the symptoms of acute kidney failure? Acute kidney failure, also known as acute renal failure, is a sudden and often reversible loss of kidney function. This can occur due to a variety of causes such as a severe infection, injury to the kidneys, or a blockage in the urinary tract.

When the kidneys are not able to function properly, they can no longer filter waste products and excess fluids from the blood, which can lead to a buildup of toxins in the body. Acute kidney failure can be life-threatening if not treated promptly, and treatment typically involves addressing the underlying cause, as well as supportive care to help the kidneys recover.

Symptoms of Acute Kidney Failure

Symptoms of acute kidney failure may include: decreased urine output, swelling of the legs, ankles, and feet, shortness of breath, fatigue, confusion, nausea, chest pain or pressure, seizures or coma in severe cases.

However, it's important to note that some people may not have any symptoms, or symptoms may be mild, making acute kidney failure difficult to detect without testing. It is important to see a doctor if you suspect you may have acute kidney failure. Acute kidney failure can get worse if the underlying cause of the condition is not treated, or if it worsens. Some examples of how this can happen include:

• If the cause of acute kidney failure is a severe infection, the infection may not be effectively treated or may spread to other parts of the body, leading to further damage to the kidneys.
  
  
• If the cause is a blockage in the urinary tract, the blockage may not be cleared or may become more severe, leading to increased damage to the kidneys.
  
  
• If the cause is a medication-induced, the dosage or frequency of the medication may need to be adjusted.
  
  
• If the cause is a lack of blood flow to the kidneys, such as in a heart attack or septic shock, the lack of blood flow may continue or worsen, leading to more damage to the kidneys.
  
  
• If the cause is a kidney disease, the disease may progress and cause more damage to the kidneys.
  
  

It's also important to note that once acute kidney failure develops, it can lead to complications such as electrolyte imbalances, fluid buildup, and waste product accumulation in the body, which can further worsen the condition.
