The first question before getting into the water is what type of access you have and whether it is fully healed. A fistula or graft and a catheter are not handled the same way, because the water-related risks and precautions are different.
Quick answer
If you have a fully healed fistula or graft and your care team has cleared you to swim, it generally does not need a special covering. A hemodialysis catheter is different: current National Kidney Foundation guidance says not to swim or submerge a hemodialysis catheter in water. Ask your dialysis team what is safe for your specific access before swimming.
Fistulas and grafts
Because a fistula or graft is fully under the skin, it doesn’t need a protective covering to swim once it’s healed. The main things to watch are water quality and post-swim hygiene, covered below.
Catheters
A hemodialysis catheter exits through the skin and has a higher infection risk than a fistula or graft. Current National Kidney Foundation guidance says not to swim or submerge a hemodialysis catheter in any water. Keep the catheter dressing clean and dry, and ask your dialysis team how to bathe or shower safely with the catheter.
Where it’s safer to swim
- Chlorinated private pools and the ocean are the lower-risk options.
- Avoid hot tubs, lakes, rivers, and ponds — these carry a higher risk of bacteria near your access.
After you get out of the water
- Shower right away to rinse off pool or ocean water near your access.
- If you have a fistula or graft, follow your usual access-care instructions after swimming. If you have a hemodialysis catheter, do not swim or submerge it in water.
Signs of infection to watch for
Contact your care team right away if you notice pain, redness, swelling, warmth, or drainage near your access, or if you develop a fever or flu-like symptoms after swimming. Catching a possible access infection early matters, since it can affect the access itself, not just how you feel.
Frequently Asked Questions
Do I need to ask my care team before swimming?
Yes, especially if you have a catheter or your fistula or graft is newly placed. Your care team can tell you whether your access has healed enough and whether swimming is appropriate for your situation.
Can I swim right after my fistula or graft surgery?
No. A new fistula or graft needs time to heal before it’s safe to submerge in water. Ask your care team when it’s appropriate for your specific access.
Is a covered catheter as safe as a fistula or graft for swimming?
No. A hemodialysis catheter is not equivalent to a healed fistula or graft for swimming. Current National Kidney Foundation guidance says not to swim or submerge a hemodialysis catheter in water.
The main thing to remember
Your access type changes the answer here more than almost any other factor. A fully healed fistula or graft may allow swimming once your care team clears you. A hemodialysis catheter should not be submerged. When in doubt, ask your dialysis team before you get in the water.
Before You Get in the Water
What is appropriate depends on the type of access, whether it is fully healed, the condition of the skin, and your care team’s instructions. A dialysis catheter requires particular caution because keeping the site and dressing protected from water is important. If you are unsure, checking with your dialysis team before swimming can help avoid guessing.
