Understanding Pyelonephritis: Top 20 Symptoms and Signs to Look Out For


Pyelonephritis, also known as a kidney infection, is a type of urinary tract infection that affects the kidneys. This condition can be severe and requires prompt medical attention. In this article, we will be exploring the top 20 kidney infection symptoms and signs of pyelonephritis, their causes, and how to seek the proper medical attention.




Pyelonephritis is a bacterial infection that affects the kidneys and the surrounding areas. It occurs when bacteria travel from the urinary tract, usually the bladder, up to the kidneys.

Pyelonephritis can be a serious condition, and prompt diagnosis and treatment are essential to prevent complications. One of the most common symptoms of pyelonephritis is a high fever, along with other signs of infection, such as chills, fatigue, and a general feeling of being unwell. If you experience any of these symptoms, it is important to seek medical attention as soon as possible. (1)

Symptom 1: High fever


A high fever is another common sign of pyelonephritis, indicating that your body is working to fight off the infection. In this section, we’ll discuss the connection between fever and kidney infections, how to monitor your temperature, and when to seek medical help.

When your body detects an infection, it raises its temperature to help fight off the invading bacteria. A fever higher than 100.4°F (38°C) is generally considered significant and can be a sign of a kidney infection, particularly if accompanied by other symptoms such as chills and sweating.

It’s essential to monitor your temperature if you suspect a kidney infection. Use a reliable digital thermometer and take your temperature at regular intervals, noting any fluctuations. Keep track of your readings, as this information will be helpful for your healthcare provider when evaluating your condition.

If you experience a high fever along with other kidney infection symptoms, it’s important to seek medical help promptly. A fever that persists despite over-the-counter fever-reducing medications may indicate a more severe infection that requires medical intervention. It’s especially important to contact a healthcare provider if your fever is accompanied by chills, sweats, or any other symptoms suggestive of pyelonephritis. (2)
