What Causes Urinary Tract Infection During Pregnancy?

Posted By :


A urinary tract infection (UTI), also called bladder infection, is an inflammation caused by bacteria in the urinary tract. Pregnant women are at increased risk for UTI’s starting from week 6 to week 24.

Why are UTI’s  common during pregnancy?

UTI’s are more common during pregnancy period due to changes in the urinary tract. Since uterus sits directly on top of the bladder, as the uterus grows, it can block the drainage of urine from the bladder, causing an infection.


Symptoms of UTI’s

The symptoms of urinary tract infection include the following:

  • Pain or burning sensation while urinating
  • The need to urinate more often than usual
  • A feeling of urgency while urinating
  • Mucus or in the urine
  • Cramps or pain in the lower abdomen
  • Chills, fever, sweats, leakage of urine
  • Pain during sexual intercourse
  • Waking up from sleep to urinate
  • Change in amount of urine, either more or less
  • Urine that is unusually strong with an odd smell
  • Pain, pressure, or tenderness in the area of the bladder
  • At adverse stages, bacteria may spread to the kidneys causing back pain, chills, fever, nausea, and vomiting.

How will the UTI affect my baby?


If left untreated during pregnancy,  UTI may lead to kidney infection which in turn may lead to early labor and low birth weight issues. If proper treatment is given appropriately, a urinary tract infection will not cause harm to the baby.

How to detect the UTI?

A urinary tract infection can be detected by a urinalysis or by a urine culture.

How to treat  Urinary Tract Infection During Pregnancy

UTI’s during pregnancy can be treated with antibiotics. Doctors usually prescribe a 3-7 day course of antibiotics which is safe to both mother and the baby. Consult the doctor immediately if fever, chills, nausea, lower stomach pains, vomiting and contractions occur after taking medicine and if the burning sensation still remains while urinating.

How to prevent a UTI?

  • Drink plenty of water: at least up to 6-8 glasses of water every day.

  • Taking Vitamin C (250 to 500 mg), Beta-carotene (25,000 to 50,000 IU per day) and Zinc (30-50 mg per day) may help to fight infection.
  • Empty the bladder completely once you urinate and try to urinate as soon as when the need is felt.
