Urinary infection

Escherichia coli: bacteria is the main cause of urinary tract infections

Which is

Urinary tract infection (UTI) is a bacterial infection that affects any part of the urinary tract. It mainly affects women, as women, unlike men, have a shorter urethra, allowing bacteria to have easier access to the bladder.


Most urinary tract infections are caused by the bacteria Escherichia coli (E. coli), which act beneficially on the intestinal tract, but when in contact with the urinary system they become harmful and cause a great deal of suffering to the patient.

Types of urinary tract infection

There are two types of urinary tract infection, the most common type being known as cystitis (urinary bladder infection), the other type of UTI is pyelonephritis (kidney infection), this type is the most severe.


The main symptoms of cystitis are pain or burning urination, frequent need to urinate with poor urine elimination, pain in the urethra, pain in the pelvis, sometimes may have a low fever and the presence of blood in the urine. In pyelonephritis the most commonly presented symptoms are usually back pain at the height of the kidneys, high fever, chills and nausea.


Treatment should be indicated by the physician after diagnostic confirmation. In this case, only the doctor can indicate the correct medication and the duration of treatment. It is very important that the treatment time is respected and followed even after the symptoms subside.

There are some important measures that can prevent urinary tract infections such as:

- Care with personal hygiene;

- Avoid transporting bacteria from the anal region to the urethra, for this, girls should be advised early on to do front-to-back hygiene when using the toilet;

- wash your hands before and after using the toilet;

- When bathing women and girls should always wash in the direction from front to back;

- During the menstrual period tampons should be changed several times as menstrual blood is a means of bacteria proliferation;

- Drink plenty of water, at least 2 liters per day.

- Do not retain urine for long periods, ideally urinate every two or three hours;

- For women suffering from UTI after sexual activity, it is recommended to drink water before and after intercourse, so that after the act, they empty their bladder as soon as possible. With this simple procedure, bacteria that may have entered the urethra are expelled.
