Frequent urination and urinary tract infections in pregnancy: telling them apart

Getting up twice in the night to use the toilet, looking for a bathroom for the second time in an hour… in pregnancy this is a very familiar picture. Most of the time it is entirely usual. But sometimes the same symptoms can hide a urinary tract infection. This article helps you tell the two apart and know when to act.

Why are you going more often?

Several things come together:

• Early in pregnancy, hormones and increased blood flow make the kidneys produce more urine.
• The growing uterus presses on the bladder, so it holds less. This is more noticeable in the first and last trimesters.
• Mild leaking can also happen when laughing, coughing or sneezing.

This is not an illness by itself and mostly improves after birth. If there is no burning, pain or bad smell, it generally does not call for worry.

Why does a urinary tract infection matter?

In pregnancy, hormones and pressure from the uterus relax the urinary tract and slow the flow of urine, which makes it easier for bacteria to multiply. If the infection stays in the bladder, it is usually easy to treat. If left untreated, it can travel to the kidney, which concerns both you and the pregnancy and may need hospital treatment. That is why catching and treating it early matters.

Which signs should you watch for?

• Burning or stinging when passing urine
• Very frequent, small amounts each time, and a feeling that the bladder is not fully emptied
• Cloudy, bad-smelling or bloody urine
• Pressure or pain in the lower abdomen
• Fever, chills, back or flank pain (can be a sign of infection reaching the kidney)

Some infections cause no symptoms at all. That is why the urine test at check-ups is important; if bacteria or white cells are found, the doctor may request a urine culture. Even bacteria without symptoms are treated in pregnancy.

How is it treated?

Treatment is planned by your doctor, with an antibiotic that is suitable in pregnancy. Do not choose the medicine yourself or reuse old prescriptions. It is important to finish it for as long as your doctor says; do not stop halfway even if symptoms ease. A follow-up urine test may be requested after treatment.

What you can do to protect yourself

• Drink enough fluids during the day; your urine should be light yellow.
• Do not hold urine; go when you need to and try to empty the bladder fully.
• Wipe from front to back after using the toilet.
• Going to the toilet after intercourse helps some people.
• Choose cotton underwear; avoid tight, synthetic clothes.
• Stay away from vaginal douches and scented hygiene products.
• Cutting back on fluids a little in the evening may reduce night-time trips, but do not cut back during the day.
• Kegel exercises may help with leaking; you can look at the Kegel programme in the app.

Ask your doctor about ready-made products or herbal mixtures; not all of them are suitable in pregnancy.

Frequently asked questions

Is frequent urination alone a sign of infection? No; without accompanying signs such as burning, pain, bad smell or blood, it is usually a usual pregnancy effect.

If I drink less, will I go less often? Drinking less can raise the risk of infection, and urine becomes more concentrated. Getting enough fluid through the day is safer.

What if I have had an infection before? Share this with your doctor; monitoring may be planned more often.

What if it keeps coming back? For repeated infections, your doctor can make a preventive plan. Do not use herbal or ready-made products on your own.

When to contact your doctor

• Burning or pain when passing urine, or cloudy, bad-smelling urine: reach your doctor the same day
• Blood in the urine
• Fever, chills, back or flank pain, nausea and vomiting: urgent assessment is needed, call 112 or go to the nearest emergency room
• If a urine test at routine check-ups is abnormal, do not delay treatment
• Signs of early labour (regular contractions, watery discharge) alongside
• Fewer baby movements
• When in doubt, asking is always right
