Impaired Renal Function: Reasons & Signal of Impaired Kidney Function

Impaired Renal Function

Kidneys are an integral part of the body’s excretory system and helps eliminate waste products from the blood, in the form of urine. Impaired renal function can be caused due to certain disease conditions or chemicals that interfere with the normal functioning of the kidneys.

As per the estimates by the National Kidney Foundation, impaired renal functions can result in renal failure, which attributes to 18 deaths per day.

Impaired Renal Function Symptoms

The symptoms of impaired renal function may vary depending upon the severity and stage of the illness.

  1. During the initial stage, the patient is asymptomatic (i.e. doesn’t exhibit any symptoms). However, as the condition deteriorates the patient may present with symptoms like weakness, lethargy, breathlessness and generalized edema and swelling over the dependent parts of the body
  2. Metabolic acidosis is a life threatening condition, which may occur as a result of the blood becoming highly acidic as the body fails to manufacture bicarbonates
  3. In severe cases hyperkalemia or elevated levels of potassium in the blood may cause arrhythmias including ventricular fibrillation or tachycardia
  4. In extreme cases mental disorientation, loss of appetite, etc may be observed.
    Coma is observed in terminally ill patients with altered kidney functions.
