Urinary Tract Infection (UTI) is one of the most common infections during pregnancy. Due to hormonal changes and pressure from the growing uterus, pregnant women are more prone to bacterial growth in the urinary tract. As a Gynaecologist with 27+ years of experience, I routinely treat UTIs in pregnancy and assure you that with timely management, both mother and baby remain completely safe.
This medically reviewed guide explains the symptoms, causes, risks, safe treatments, prevention tips and warning signs of UTI during pregnancy.
Why Are Pregnant Women More Prone to UTIs?
The pregnancy hormone progesterone relaxes the urinary tract muscles, slowing urine flow. The growing uterus also presses on the bladder, making it difficult to empty fully. These factors make it easier for bacteria to multiply.
Common Causes of UTI in Pregnancy
- Bacteria (E. coli) from the intestine entering the urinary tract
- Incomplete bladder emptying
- Low immunity
- Poor hydration
- Improper wiping (back to front)
- Tight clothing
- Frequent sexual intercourse without hygiene
Symptoms of UTI During Pregnancy
Seek medical help if you notice:
- Burning while urinating
- Frequent urge to urinate
- Lower abdominal pain
- Cloudy or foul-smelling urine
- Pelvic discomfort
- Blood in urine (in some cases)
Important: Some pregnant women have “silent UTIs” with no symptoms. This is why urine tests during antenatal visits are essential.
Risks of Untreated UTI in Pregnancy
If not treated on time, UTI can lead to:
- Kidney infection (pyelonephritis)
- Preterm labour
- Premature rupture of membranes
- Low birth weight
- Severe fever & dehydration
Early treatment prevents these complications.
Types of UTI in Pregnancy
1. Asymptomatic Bacteriuria
Bacteria present in urine without symptoms. Must be treated to prevent kidney infections.
2. Cystitis (Bladder Infection)
Burning urination, urgency, pelvic pain.
3. Pyelonephritis (Kidney Infection)
Severe condition with fever, chills, vomiting, back pain. Requires urgent medical care.
How UTI Is Diagnosed During Pregnancy
- Urine routine and microscopy
- Urine culture (gold standard)
- Sensitivity tests to choose safe antibiotics
Safe Treatment Options for UTI (Pregnancy Approved)
Treatment depends on type and severity:
1. Antibiotics
Common doctor-approved antibiotics include:
- Amoxicillin
- Cephalexin
- Nitrofurantoin (avoid near term)
These are safe in pregnancy when prescribed by a doctor.
2. Hydration
Drink 2–3 litres of water daily to flush out bacteria.
3. Pain Relief
Certain medicines may be prescribed if pain is severe.
4. Hospital Care
Required in cases of kidney infection, high fever or dehydration.
