Pyelonephritis: kidney infection in pregnancy
Pyelonephritis is an infection which has travelled up the urinary tract and has reached the kidney. This condition should always be treated promptly.
The symptoms of pyelonephritis usually develop over just a few hours, and they can come on very suddenly.
Symptoms of pyelonephritis (kidney infection)
Symptoms of pyelonephritis may include:
- pain in the lower side of your back, on either side or both sides
- feeling sick
- blood in your urine
- your urine turning cloudy and smelling unusually bad
- pain when you pass urine
- needing to go to the toilet more often than normal.
Pyelonephritis is usually treated with antibiotics to clear the infection when you are pregnant. It may require admission to hospital.
If you are worried about any of these symptoms, see your midwife or GP or contact NHS Direct: 0845 4647.
