What can I cover my incisions with to swim in the ocean at 3 weeks post op BA?

Thank you for your question. There is no reason why you can't go for a dip in the ocean 3 weeks after breast augmentation provided your incisions have healed normally. I advise my patients that they can shower the day after surgery, and go in the lake or ocean 1 week after. I would not advise swimming laps or actively swimming in the ocean because of the potential for swelling or pectoralis muscle cramps, but not infection. Of course you should discuss this with your surgeon before taking the plunge. Good luck.

I do not recommend that my patients swim in the ocean only three weeks following breast augmentation.  It probably would be OK, but there is likely some extra risk of infection. Definitely be certain that the wounds are healed before the swim.

I don't allow my patients to submerge in bodies of water for extended periods for at least 6 weeks after surgery.  I'm rather conservative.  

Your skin incision will heal within just a few days. I allow my patients to submerge in water for short times, 4 days after surgery. Speak with your surgeon and ask for specific recommendations as this will depend on the surgical technique that your surgeon uses.

Once the incision is healed and not draining (usually about a week) the skin protection barrier is intact and submerging should not be an issue. Swimming vigorously is a separate issue, as it takes about 6 weeks for the healing strength to approach 90% of its ultimate strength, and that is usually the guideline for return to full activity. Hopefully you will see your surgeon before you leave for advice. All the best.
