Chemical Urethritis from Swimming Pool

Swimming pools require chemicals like chlorine to keep them clean and safe for swimming by killing germs. However, if these chemicals are not used properly or if too much is added, they can lead to health issues like chemical urethritis. This condition involves inflammation in the urinary tract, which can occur from swimming in the pool.

What is Chemical Urethritis?

Chemical urethritis occurs when the urethra, the tube connecting the bladder to the outside, becomes inflamed and irritated. This can happen because pool chemicals like chlorine irritate the sensitive lining of the urethra when they touch it.

Chemical urethritis can be caused by several factors related to swimming pool:

Over Chlorination

If there’s too much chlorine in a pool, it can irritate the tube that carries pee from the bladder (urethra) if people spend too much time in it. This can occur when chlorine levels are too high due to incorrect measurements or not monitoring them carefully.

Improper pH Levels

It’s crucial for swimming pool water to have the correct pH balance. If the pH is too high or too low, it can irritate the tube that carries pee from the bladder (urethra) when people swim. This can occur if the pool isn’t taken care of properly or if regular water testing isn’t done.

Poor Water Circulation

When a swimming pool doesn’t circulate water well, impurities like chemicals, urine, sweat, and other body fluids can build up. If people swallow this dirty water, it can lead to discomfort and inflammation in the tube that carries pee from the bladder (urethra).

Symptoms of Chemical Urethritis

Chemical urethritis can cause different symptoms, such as:

  • Burning or stinging when peeing: People may feel a burning or stinging sensation when they pee.
  • Peeing more often: People might need to pee more often than usual.
  • Feeling like you have to pee urgently: Even if your bladder isn’t full, you might feel like you urgently need to pee.
  • Discomfort or pain in the pee tube: The tube that carries pee might feel uncomfortable or painful because it’s inflamed.
  • Seeing blood in your pee: Sometimes, there might be blood in the pee, which needs to be checked by a doctor.
  • Cloudy or smelly pee: Pee might look cloudy and have a bad smell because of the irritation from chemical urethritis.

Prevention of Chemical Urethritis

To prevent chemical urethritis from swimming pool, consider the following preventive measures:

Choose Well-Maintained Pools

Pick swimming pools that take good care of their maintenance. Make sure the pool you go to regularly checks and keeps the chlorine and pH levels right.

Shower before Entering the Pool

Before you hop into the pool, take a fast shower to rinse off any oils, dirt, or sweat from your body. This helps stop these things from mixing with pool chemicals and making you uncomfortable.

Limit Pool Water Exposure

If you can, spend less time in the pool, especially if it feels uncomfortable or smells strongly of chlorine. Take breaks out of the water to reduce your exposure to potentially unpleasant stuff.

Stay Hydrated

Drink plenty of water before and after swimming. This keeps your urinary system healthy and helps flush out any potential irritants.

Here are the treatment options for chemical urethritis:

  • Drink plenty of water: Staying hydrated is important to keep your urinary tract healthy and flush out irritants. Drinking enough water can dilute urine and reduce pain.
  • Avoid further exposure: It’s best to avoid swimming in pools and other irritating environments until symptoms improve. Prolonged exposure to chemicals can make pain and inflammation worse.
  • Over-the-counter pain relievers: Ibuprofen, paracetamol, and NSAIDs (nonsteroidal anti-inflammatory drugs) can help reduce inflammation and pain. Follow the recommended dosage and consult a doctor if needed.
  • Warm sitz baths: Soaking in warm water can temporarily ease discomfort and soothe the inflamed urethra. Make sure the water isn’t too hot and avoid harsh soaps or bath products.
  • Prescription medication: In severe cases or if symptoms persist, a doctor may prescribe medication to reduce inflammation and provide relief. Follow the treatment plan and consult the doctor about any concerns or side effects.


Understanding the risks of chemical urethritis is crucial, even though swimming pools can be enjoyable. You can greatly reduce urinary discomfort by choosing a clean, well-maintained pool and being careful around water. If you experience any symptoms, seek prompt medical attention for proper diagnosis and treatment.
