Bacterial infection (E. coli): Bacteria near the anus (especially E. coli) enter the urethra in 90% of cases.
Personal hygiene: Not cleaning properly after urinating, or cleaning in a way that allows bacteria to enter the urethra from near the anus.
Drinking less water: Drinking less water reduces the amount of urine and causes bacteria to multiply in the bladder.
Delaying urination: Holding urine for a long time creates a favorable environment for bacteria to grow.
More likely in women: Since women’s urethra is shorter than men’s, bacteria can reach the bladder more easily.
Sexual intercourse: Poor hygiene after sexual intercourse can also cause infection.
Other medical conditions: People with diabetes, kidney stones, and bladder obstructions are more likely to develop infection.
