Infecçãourinária in pregnancy: main symptoms and risks

It is normal to have at least one episode of urinary tract infection during pregnancy, as the changes that occur in a woman's body during this period favor the development of bacteria in the urinary tract.

Although it may seem scary, a urinary tract infection does not harm the baby and can be easily treated with antibiotics such as Cephalexin. However, if the woman does not start treatment, the infection can continue to worsen and cause some risks for the baby, such as premature birth or miscarriage, for example.

Therefore, whenever signs of urinary discomfort appear, it is very important that the pregnant woman consults the obstetrician or gynecologist to perform a urinalysis and start treatment if necessary.

Possible symptoms of urinary tract infection

During pregnancy, urinary tract infection can be a little more difficult to identify, so select what you are feeling to assess your risk of having a urinary tract infection:

  1. 1.Pain or burning sensation when urinating Yes No
  2. 2.Frequent and sudden urge to urinate in small amounts Yes No
  3. 3.Feeling of not being able to empty the bladder Yes No
  4. 4.Heaviness or discomfort in the bladder region Yes No
  5. 5.Cloudy or bloody urine Yes No
  6. 6.Persistent low-grade fever (between 37th, 5th and 38th) Yes No


Make an appointment with a specialist

Some of these symptoms, such as the frequent urge to urinate or a feeling of heaviness in the bladder, are very common during pregnancy and, therefore, can be disguised. Thus, whenever the woman identifies any alteration or discomfort, she should consult the obstetrician or gynecologist to perform a urinalysis and assess whether an infection may be occurring.

How to confirm the diagnosis

The diagnosis of urinary infection during pregnancy is made through a normal urinalysis, whenever there are warning symptoms. However, the doctor should also order 1 urinalysis per quarter in order to identify and treat a possible urinary infection early, even if there are no symptoms.

In addition, women can also buy a home test for urinary tract infection at the pharmacy. See more at: How to do a home exam to detect urinary infection.

How the treatment is done

Treatment of urinary infection in pregnancy is usually done with the use of antibiotics, such as cephalexin, for a period of 7 to 14 days, it is also important to drink plenty of water, not hold the pee and empty the bladder completely every time you urinate.

In cases where the infection has worsened and reached the kidneys, the pregnant woman may need to stay in the hospital to take antibiotics directly into the vein. Learn more about treatment for urinary tract infection in pregnancy.

Infection risks for the baby

If the urinary tract infection is not treated properly during pregnancy, there can be complications for both mother and baby, such as:

  • Premature birth;
  • Decreased intrauterine growth;
  • Low birth weight;
  • Pneumonia;
  • Asthma in childhood;
  • Spontaneous abortion.

In addition, urinary tract infection during pregnancy also increases the risk of death of the baby after delivery. Thus, the best way to avoid all these risks is to be attentive to the symptoms of urinary tract infection and to follow the treatment indicated by the doctor as soon as the disease is diagnosed.
