Causes Of Kidney Infection


Kidney Infection Also known as pyelonephritis, the term kidney infection refers to a bacterial infection that attacks the human urinary tract. The infection starts in the urethra and urinary bladder, very fast affecting the tube from where urine is passed out of the body from the bladder and reaching the kidneys.

Though kidney infection is not very painful, it must be dealt with on time in order to avoid serious complications. According to a report published by the National Health Service, more women than men are likely to be affected by kidney infection. It is important to identify the causes of this ailment so that you can consider treatment options or adopt preventive measures. Listed below are some of the causes of kidney infection.

Kidney Infection Causes


One of the chief causes of kidney infection in women is sex. This is because of the fact that a woman’s urethra is small in size when compared to a man’s. The bacteria thus have to travel just a short distance to reach the urinary bladder and from there enter the rectum from the opening in the vagina.

Sexual intercourse, especially with multiple partners, leads to spread of bacteria from the vagina. It may also occur in women who are having sex the first time or start making out too frequently during the day.


Risk of attracting the bacteria which are responsible for infecting kidneys in women increase after a woman enters menopause. This is because of the fact that the levels of the estrogen hormone in a woman’s body falls drastically after menopause; this in turn leads to the thinning of the walls in the urinary tract.


The E Coli bacteria build up in the vagina and easily pass on to the kidneys since the skin cells are too thin to stop the transfer of infectious bacteria.


More than five out of ten women suffer from kidney infection in the early stages of pregnancy. Chances of acquiring the infection are at the maximum from week 6 to week 24 of pregnancy. This is because of the fact that when the uterus suddenly grows in size, it leads to blockages in the urinary tract that prevent urine from leaving your system. The toxic substances in the urine lead to infections in the kidney.

Weak Immune System

Bacteria are always present in the surrounding atmosphere and the food and water you consume. They remain in the bloodstream and attack the kidneys frequently.

Weak Immune System

If the immune system is very weak, the human body will fail to fight these microorganisms leading to serious infections.

Poor Toilet Hygiene

Cleanliness in the toilet must be maintained. Using public toilets too frequently increases the chances of bacterial infections that soon attack the kidney. While wiping the anus with toilet paper, the paper may come in contact with your genitals and lead to spread of bacteria that eventually attack the kidney.

Kidney Stone

When stones develop inside your kidneys, there is a buildup of minerals lining the inner wall of the kidneys. This acts as a blockage that prevents urine from flowing out of the body properly and leads to kidney infection.
