Coughing spasm w/blood in it when swimming in pool treated w/chlorine

Posted by pammie52 @pammie52, Dec 4, 2025

I’m on vacation and have been swimming in a pool treated with chlorine. Every time I do I start coughing up small red blood clots and/or sputum which has bright red blood mixed in it. I’ve been on Brinsupri since October. Has anyone else had this issue. Plan on talking with my Pulmonologist when I go home.

Interested in more discussions like this? Go to the MAC & Bronchiectasis Support Group.

Yes! I am not on Brinsupri. I now only walk in the pool, no actual swimming.

I have coughed a lot of blood maybe once or twice a year. I nebulize with 7% saline. When I do cough blood my Dr puts me on antibiotics for 10 days and it will stop the bleeding.. I have had bronchiectasis/MAC for over 5 years I exercise and do yoga postures to get rid of the mucus and most of the time it has worked for me.

I went swimming in the summer (outdoor pool) and coughed up blood too.

@pammie52 @rstel7272 @sweethighland Wow, I don’t know how I missed this post. My one and only hemoptysis, which lead to my diagnosis of BE/MAC, happened after swimming in a swimming pool at a resort. It was the first time swimming in a pool in years (and last time as well!) It never occurred to me there may be a connection to the chlorine used in the pool. We were at a resort celebrating my birthday and spent the whole day at the pool. The next day I woke up with a pool of blood on my pillow. Had no idea what was happening, felt totally fine. Took myself to the ER because it was just so weird, and, well, the rest is history. No hemoptysis (and no swimming pools) since (over 1.5 years now). So interesting that others have also had hemoptysis after swimming in pools. My husband and I have frequently commented on how crazy it was to one day be celebrating and the next day be thrown into the crazy BE/MAC world. Again, it never occurred to us that there might be a connection between the two. Interesting.

@bayarea58 So sorry you had to go through that right after your birthday celebration. When I coughed up blood in 2024, I was just dipping in the water and floating, not even swimming which spread out the lungs. It just happened and had to get out from the pool. Some say if you stretch out your lungs during exercise, it can bleed too. I have no idea. I hope no more bleeding for you.

@sweethighland yes, I have read about stretching the lungs causing hemoptysis. We were swimming and frolicking in the pool all day. Lots of play. But I am very active generally so hard to say. Though at my age I am definitely able to move my body in water in ways I can no longer move it on land. 🤣🤣🤣. Perhaps it was the endless backward flips in the pool that triggered the bleeding.

@bayarea58 not to make light of any of this but it gives you a great story to tell! I don’t think many of us can point to backflips leading up to this - let alone doing one!

Oh no....I have not put myself in my swimming pool for a couple of years due to not knowing if it would or would not bother the unexpected diagnosis of Eczema that was diagnosed about the same time I received the diagnosis of BE.
I have recently been thinking I will use that 'money pit' this summer. Especially since the dermatologist said the chlorine is O.K. with Eczema and can be helpful.
So now, after reading the recent posts because I did not see the original post, I don't think, I might not be swimming in the pool.
However, if I understood correctly our volunteer has said she has swam in a pool and apparently has not had any problems.???
I wonder if it is the type of bacteria one has and of course the actual condition of the lungs themselves with or without a bacteria????
I wonder if the chemical ratio of the pool water chemicals had anything to do with it..... especially a public swimming pool (indoor or outdoor) verses a homeowner's outdoor swimming pool...where one is diligent about the balance of the chemicals and range of each chemical ?????
I wonder if the swimming pool had had problems with pseudomonas to begin with???
@bayarea58 @sweethighland@pammie52 After the bleed and or before the bleed in the swimming pool were you then diagnosed with a bacteria or had you been previously diagnosed with a type of bacteria before the swim and bleed? Were they indoor pools, hot tubs, or outdoor???

@blm1007blm1007, i think they mentionned swimming in a chlorine pool. They might not have hemoptysis had the pool been saline treated instead of chlorine.
By the way, Barbara, I wanted to thank you for that Amazon link for the long handle knot massager. It helps greatly perform percussions!
Best wishes of great health to all of us!

@blm1007blm1007 I would assume if there is in fact any connection between the pool and the hemoptysis it would be some sort of irritation from the chlorine with regard to the bronchiectasis (“BE”) (or maybe those backflips). The pool I was in was outdoor at a large resort, very busy, I assume it was heavily chlorinated. I did not have any history of lung infection/disease when I went to the ER, I would have told you then that my lungs were fine - it was quite a shock. I was eventually diagnosed with MAI, after sputum, but I doubt the MAI came from the pool or that an initial exposure of MAI would cause hemoptysis overnight. I have advanced disease so I must have had the MAI for some time and didn’t know it. As for whether swimming pools are safe for those of us at heightened risk for lung infections, the information I have seen/heard seems all over the place. I think it’s safe to say indoor pools are a hard no, but outdoor pools … well, we each have to decide what our comfort level is with what seems largely unknown/unstudied. For now, myself, I am staying out of pools, but it makes me sad. And if I were in my 80’s I don’t know that I would give up something so joyful when the risk seems so uncertain.
