UTI’s - What is a urine infection and what causes it?
Most urine infections are caused by germs
(bacteria) that come from your own bowel. They cause no harm in your bowel but
can cause infection if they get into other parts of your body. Some bacteria
lie around your back passage (anus) after you pass a stool (faeces). These
bacteria sometimes travel to the tube from the bladder that passes out urine
(the urethra) and into your bladder. Some bacteria thrive in urine and
multiply quickly to cause infection.
A urine infection is often called a urinary
tract infection (UTI) by doctors. When the infection is just in the bladder and
urethra, this is called a lower UTI. If it travels up to affect one or both
kidneys as well then it is called an upper UTI. This can be more serious than
lower UTIs, as the kidneys can be damaged by the infection.
