Urinary pus and burning sensation is a health problem that is common in both men and women, but it bothers women more. Frequent urge to urinate, pain and burning sensation when urinating, urine that is discolored and foul-smelling, and sometimes fever and chills—these are the symptoms of a urinary tract infection, or UTI. This condition occurs when bacteria enter our urinary tract and multiply there. Here are 5 main scientific reasons behind it:
E. coli Bacterial Infection: Escherichia coli (E. coli) is the scientific cause of 80 to 90 percent of pus in urine. These bacteria, which are naturally found in our digestive system and around the anus, enter the urethra due to unhygienic conditions or improper washing, and from there, spread to the bladder, causing pus.
Dehydration: When we do not drink enough water, the amount of urine decreases and it becomes more concentrated and acidic. This can cause severe burning in the urethra. Also, when we do not urinate properly, the body is unable to flush out the bacteria in the urethra. This creates a favorable environment for bacteria to lie there and multiply rapidly.
Female Anatomy: Urinary pus is much more common in women than in men. The urethra in women is much shorter than that of men. Also, the distance between the anus and the urethra is very small, so bacteria can easily spread to the bladder. Women who do not urinate and wash after sex are also at higher risk of UTI.
Urinary Retention: Many people hold urine for a long time, whether during travel, work, or due to lack of clean toilets. When urine is left in the bladder for hours, it becomes a breeding ground for bacteria. This can cause inflammation of the bladder (cystitis) and severe pus.
Decreased immunity and other diseases: In people with diabetes, the increased glucose level in the urine provides food for bacteria to grow quickly. In addition, hormonal changes during pregnancy and menopause can also increase pus in the urine. Kidney/Bladder Stones that cause urinary obstruction can also cause pus.
