With summer quickly approaching, interstitial cystitis patients are asking “Is it safe to swim?” The answer is complex. Swimming is an ideal exercise for patients struggling with chronic bladder or pelvic pain. It’s gentle, non weight-bearing and minimizes trauma to the pelvic floor. Sounds great, right? The challenge, unfortunately, are the chemicals (specifically the chlorine and acid) used to make pool water bacterial free.

A Swimming Pool Accident Triggered My Bladder Pain

Jill OsborneMy bladder pain first began after a terrible swimming pool mishap. I had been distance swimming at a private club for years with no problems. One day I noticed some flakes in the water that were settling on the bottom of the pool. I thought it was unusual but I wasn’t alarmed. I continued to swim for about 40 minutes, then got out took my normal shower and went on with my day.

I didn’t feel bladder pain until that night. It felt like a terrible bladder infection and that my bladder was on fire. By the next morning, I had to wonder about those suspicious flakes that I saw in the water and called the pool manager. I asked “Was anything going on with the pool yesterday?” He said “Why?” I said “Well, I swam yesterday and….” He interrupted me and said “Wait, you swam yesterday? Wasn’t the closed sign up?” I said “No.” He said “We bombed the pool yesterday. Noone was supposed to swim in it for 24 hours.” I then explained that I was having some very unusual bladder problems and his answer was astounding. He said “Yeah, we’ve had other women complain of that too.” Hours later, my urologist diagnosed me with chemical induced cystitis, soon to become interstitial cystitis.

I liken it to a burn. Think acid on a wound and that’s how my bladder felt. In that first year, I rarely slept more than an hour without having to urinate. I would cry driving in the car every time I hit a speed bump. I eventually lost my job, my health insurance and my boyfriend all the while thinking, deep inside, that I was dying of cancer. Of course, I wasn’t. I had sustained a terrible bladder injury from a swimming pool that I wouldn’t wish that on anyone else.

Since then, I’ve talked with several other patients whose symptoms began after a pool incident. One was a swimming coach at a major university who had spent a years in a pool before her bladder symptoms began. Another was an older lady who ordered a new hot tub. The day it was installed, she asked if she could sit in it immediately. The installer said “yes” and savor it she did having no clue that she was sitting in fresh pool chemicals. She, too, developed severe bladder pain.

So, the answer to my original question isn’t as easy as it sounds. Can you swim? Yes, but I don’t want what happened to me (and others) to happen to you. I encourage you to be very cautious about where you swim.

About Pool Chemicals

Three types of chemicals are often used in pools. Disinfectants (i.e. chlorine) are used regularly to destroy bacteria. pH adjusters (either acids or alkalizes) are used to maintain a consistent acid-base relationship. Algaecides are used to kill and prevent algae.

If pool water is too acidic, skin and eye irritation can occur as well as corrosion to pipes and damage to the walls of the pool. If the water is too alkaline, the water can become cloudy or hazy. The goal for pool managers is to keep the pH between 7.2 and 7.8 and this must be tested regularly. If the pH is too acidic, the pool will be treated with a pH Increaser, usually soda ash. If the pH is too alkaline, it may be treated with an acid, such as muriatic acid.

I suspect that pool I had been swimming in had been treated with a fast acting “pool shock” chemical: a more powerful, intense treatment, either chlorine to kill bacteria or a pH adjuster. I was never told what specifically was done and I never did return to the pool. I miss swimming terribly and I’ve only swum a few times in the past twenty years. That accident robbed me of years of my life.

Five Tips To Swim Safely

  1. blog-clearwaterLook at the water. Is it clear or cloudy? Blue or Green? – If the water is cloudy and/or has a greenish tinge to it, the pool may be improperly treated. Take note of any leaves or other solids sitting at the bottom of the pool? Is algae growing on the sides? These all point to a pool that may not have been properly maintained!
  2. Ask when was the pool last treated. – Whether a large community pool or a neighbors back yard pool, it’s important to ask when the pool was last treated. If it was treated that day, ask if a “shock treatment” was done. Ask what the proper waiting period is until the water is safe. Also, if you’re swimming in a neighbors pool, it’s worth asking who is responsible for it. A pool company, for example, might be more reliable than someone who has no experience working with chemicals.
  3. Is there a strong odor of chlorine? – This can be good or bad. Clearly, it shows that the pool has been treated but could it be too much? I know, as a veteran swimmer, that there were times when chlorine levels were so high that it literally oozed off of my skin and out of my hair for hours afterwards. The last time I walked into our low YMCA’s pool, I was practically knocked over by the chlorination smell which told me that they had concerns about bacterial levels due, most likely, to the number of young children who used it. Out of instinct, I chose not to swim in such a large, public pool.
  4. Try a pool using bromine, rather than chlorine. – Bromine is generally mu
