Signs of Kidney Infection

It's important to know the signs of kidney infection, especially if you are prone to urinary tract infections. A kidney infection usually starts as an urethra or bladder infection that travels up into the kidneys, where it progresses from unpleasant to medically serious. Because a kidney infection can cause life-threatening complications, it's important to seek medical attention if you suspect you may have one.

Signs of a Bladder Infection:

  • Painful Urination: The pain may be intense and burning, or it can be dull and persistent. You may feel as if you have to urinate, but when you try to empty your bladder, it hurts terribly and you can only release a small dribble of urine.
  • Frequent Urination: The worse the infection gets, the most intensely you will feel like you have to urinate. It may seem like you have to urinate continuously, and yet your body can only produce a small amount of urine.
  • Fever: Even a low-grade fever can be a sign of a bladder infection.
  • Discolored Urine: You may see pus or blood in your urine. This can color your urine so it looks cloudy or streaked with red.

Signs Your Bladder Infection Has Become a Kidney Infection

  • Back or Flank Pain: If you develop pain in your back or flanks, you should get into the doctor right away to be checked for a kidney infection. The pain may be stabbing or it may be a deep, dull ache.
  • Overall Discomfort: If you suddenly feel very unwell, and the fever, painful urination and pain in your back has increased significantly, you probably have a kidney infection. You will most likely feel terrible and realize something is wrong.
  • Nausea and Vomiting: When a kidney infection gets serious, it can cause you to vomit. Take this as a sign that you need to get to a doctor.

Kidney infections can cause kidney failure or an extensive infection in your bloodstream that can be very serious.

Symptoms of Kidney Failure

  • Arrythmia: An irregular heartbeat can result from an excess of potassium in the blood.
  • Anemia: This is a general feeling of weakness and fatigue brought on by a shortage of red blood cells.
  • Congestive Heart Failure: Rapid breathing and a buildup of fluid in the lungs can occur as your body looks for other ways to purge toxins from the blood. If enough fluid enters the lungs, the heart can fail.
