What are kidney infections? Failing to treat a urinary tract infection can lead to serious health problems, including kidney infections. If you have lingering symptoms, or recurrent UTIs, it is important to see your medical provider. Kidney infections, also referred to as pyelonephritis, are a serious type of urinary tract infection (UTI). This infection occurs when bacteria enter the urinary tract, spread to the bladder, and then continue spreading until they reach one or both kidneys. Kidneys are vital organs in your body since they are responsible for trapping and removing waste products and toxins through urine. Depending on the individual, you may start experiencing symptoms of kidney infection as soon as two hours after your kidneys get infected. Kidney infections usually occur when the bacteria multiply and are not treated in time. Fortunately, most complications can be avoided with quick treatment. Can a UTI become a kidney infection?The urinary system doesn’t ordinarily contain bacteria. However, bacteria such as Escherichia coli (E. coli) and others found in the intestines can get into the urinary tract. This can cause cystitis (inflammation of the bladder), and it can also cause a UTI. If a UTI spreads to the kidneys, they may fail to function properly. As a result, your blood can easily get infected, which may lead to a life-threatening condition called sepsis. Frequent bladder infections, structural problems in the urinary tract, or blockage by kidney stones can easily lead to kidney infections as well. The normal flow of urine is from the kidneys down to the bladder. If the urine flows in the wrong direction, kidney infections may also occur.
Causes of UTIsHaving bacteria in the bladder will not always cause a UTI. Other factors also contribute to high chances of contracting UTI. These include: Sex. A woman has a shorter urethra compared to a man. This allows the bacteria to quickly access the bladder. The urethral opening of a woman is also close to the anus and vagina, which are common sources of bacteria. Bacteria can easily spread to the urethral opening during sexual intercourse. Lack of enough water in the body. Your body requires a lot of water to flush out any bacteria and waste in your body. Less water in the body causes bacteria to stay and multiply in the bladder. Holding urine for long periods. Holding urine for a long period of time encourages bacteria to build up. This increases the chance of contracting UTIs. Hormonal changes during pregnancy. When hormonal changes occur during pregnancy, that makes it easier for bacteria to spread through the urinary tract, causing UTIs. Conditions blocking normal urine flow. Sexual intercourse, kidney stones, an enlarged prostate, or a tumor can easily block the flow of urine, making room for infection. Diabetes or a weak immune system. People with diabetes and weak immune systems are at risk since their immune systems are often not strong enough to fight off infections. Use of catheters. These are tubes placed in the urethra and bladder to help drain urine. Symptoms of a urinary tract infectionSymptoms of UTI include:
