A UTI is an infection in the urinary tract typically caused by bacteria. UTIs are more common during pregnancy because the growing fetus can put pressure on the bladder and urinary tract. This can trap bacteria or cause urine to leak.
Read on to learn more about the symptoms and treatment of UTIs, and other causes of blood in the urine.
Symptoms of a UTI may include:
- persistent urge to urinate
- frequently passing small amounts of urine
- burning sensation when urinating
- discomfort in the center of the pelvis
- back pain
- unpleasant smelling urine
- bloody urine (hematuria)
- cloudy urine
There are three major types of UTI during pregnancy, each with distinct causes:
Asymptomatic bacteriuria is often caused by bacteria present in a woman’s body before she became pregnant. This type of UTI doesn’t cause any noticeable symptoms.
This infection occurs in about 1.9 to 9.5 percent of pregnant women.
Acute urethritis or cystitis
Both of these conditions are caused by bacterial infection. They’re often caused by a type of Escherichia coli (E. coli).
Pyelonephritis is a kidney infection. It can be the result of bacteria entering your kidneys from your bloodstream or from elsewhere in your urinary tract, such as your ureters.
Along with blood in your urine, symptoms may include fever, pain when urinating, and pain in your back, side, groin, or abdomen.
Doctors commonly use antibiotics to treat UTIs during pregnancy. Your doctor will prescribe an antibiotic that is safe for use during pregnancy but still effective in killing bacteria in your body. These antibiotics include:
Blood leaking into your urine could be caused by a number of conditions, whether you are pregnant or not. This may include:
- bladder or kidney stones
- glomerulonephritis, an inflammation of the kidneys’ filtering system
- bladder or kidney cancer
- kidney injury, such as from a fall or vehicle accident
- inherited disorders, such as Alport syndrome or sickle cell anemia
The cause of hematuria cannot always be identified.
Although hematuria is often harmless, it can indicate a serious disorder. If you’re pregnant and you see blood in your urine, make an appointment with your doctor.
