Urinary Tract Infection in Pregnancy


A urinary tract infection (UTI)

is caused by bacteria that get inside your urinary tract. The urinary tract includes your kidneys and bladder. UTIs are common during pregnancy. This is because of changes in your immune system, hormones, and uterus. As your uterus grows, your bladder may not completely empty. Bacteria can grow in the urine left in your bladder and cause a UTI. UTIs during pregnancy can increase your risk for a kidney infection and preterm labor.

Female Urinary System

Commons signs and symptoms of a UTI:

  • Urinating more often, leaking urine, or waking from sleep to urinate
  • Pain or burning when you urinate
  • Pain or pressure in your lower abdomen
  • Urine that smells bad
  • Blood in your urine

Seek care immediately if:

  • You are urinating very little or not at all.
  • You have severe pain.
  • You have a fever and chills.

Call your doctor or obstetrician if:

  • You have pain in the sides of your back.
  • You do not feel better after 2 days of treatment.
  • You are vomiting.
  • You have questions or concerns about your condition or care.


Antibiotics may be given to kill bacteria that are causing your infection. Medicines may be given to decrease pain and burning when you urinate, or decrease the need to urinate often. These medicines will make your urine orange or red.

Prevent a UTI:

  • Urinate when you feel the urge. Do not hold your urine. Urinate as soon as needed. Always urinate after you have sex. This helps flush out bacteria passed during sex.
  • Drink liquids as directed. Ask how much liquid to drink each day and which liquids are best for you. You may need to drink more fluids than usual to help flush bacteria out of your urinary tract. Do not drink caffeine or carbonated liquids. These drinks can irritate your bladder. Your healthcare provider may recommend cranberry juice to help prevent a UTI.
  • Wipe from front to back after you urinate or have a bowel movement. This will help prevent germs from getting into your urinary tract through your urethra.
  • Do pelvic muscle exercises often. Pelvic muscle exercises may help you start and stop urinating. Strong pelvic muscles may help you empty your bladder easier. Squeeze these muscles tightly for 5 seconds like you are trying to hold back urine. Then relax for 5 seconds. Gradually work up to squeezing for 10 seconds. Do 3 sets of 15 repetitions a day, or as directed.

Follow up with your doctor or obstetrician as directed:

You may need to return for more urine tests. Write down your questions so you remember to ask them during your visits.
