Introduction
Pyelonephritis is a type of kidney infection that can cause serious health problems if not treated. This condition often starts as a urinary tract infection (UTI) and then spreads to the kidneys. Because pyelonephritis can become severe, it is important to know its causes and symptoms. Early treatment helps prevent complications and keeps your kidneys healthy.
What Is Pyelonephritis?
Pyelonephritis is a sudden or long-term infection of one or both kidneys. The kidneys are organs that filter waste from your blood and make urine. When bacteria travel up the urinary tract and reach the kidneys, they can cause this infection. Usually, pyelonephritis is more serious than a simple bladder infection. In some cases, it can lead to kidney damage if not treated quickly.
Doctors often call pyelonephritis a kidney infection. It is different from other urinary tract infections because it affects deeper parts of the urinary system. While anyone can get pyelonephritis, women, pregnant people, and those with urinary problems are at higher risk.
Causes of Pyelonephritis
Most cases of pyelonephritis are caused by bacteria. These germs usually enter the body through the urethra, which is the tube that carries urine out of the body. Then, they travel up to the bladder and finally reach the kidneys. Escherichia coli (E. coli) is the most common bacteria that causes this infection.
However, there are other reasons why someone might get pyelonephritis. For example, problems that block the flow of urine can make it easier for bacteria to reach the kidneys. Some common causes include:
Sometimes, bacteria can enter the kidneys from the bloodstream, but this is less common. Either way, knowing the causes helps you take steps to lower your risk.
Symptoms of Pyelonephritis
Pyelonephritis symptoms can appear quickly and may be severe. Because the infection affects the kidneys, you might feel much worse than with a simple UTI. Common symptoms include:
Sometimes, children and older adults may not have the usual symptoms. Instead, they might feel confused or have stomach pain. Because symptoms can get worse quickly, it is important to seek medical help if you notice any of these signs.
Conclusion
In summary, pyelonephritis is a serious kidney infection that needs quick treatment. It often starts as a urinary tract infection and can lead to severe symptoms. Knowing the causes and signs can help you act fast. If you notice symptoms of pyelonephritis, consult a healthcare specialist for proper diagnosis and treatment.
