'Sloshing' Since the Day of my Surgery Last Week. How Soon Does That Go Away?

The sloshing sound you hear after a breast augmentation is because air was allowed to get in through the incision through which your breast implant was placed.  Also, in the process of preparing your breast pocket for implantation, your surgeon places saline and other liquids into the pocket which are not completely removed.  A combination of air and liquid in your breast pocket along with the implant, in some patients, leads to a sloshing sound.  Both the air and the fluid will be reabsorbed by your body over the first couple weeks after surgery. 

The sounds you hear are completely normal and nothing to worry about.

This noise is completely normal. When a breast augmentation is performed an antibiotic irrigation is used in both pockets. This along with air that has gotten into the pocket can cause that slushing or gurgling noise. Typically it takes a couple of weeks for this to resolve, but is no harm to yourself and/or the implants. Make sure to follow up with your Physician regularly to ensure adequate healing.  

It’s perfectly normal. Women hear their implants slosh, gurgle, squeak, crackle, and even “talk” to them. It’s not the implants that are making noise; the sounds are coming from antibiotic fluids that were used during surgery and/or from the air that has built up in the pocket around the implant. As your body absorbs the
fluid and the air bubbles, the sounds disappear – usually three to five weeks after surgery.

This is quite common and typically lasts 7-10 days but may persist up to 3 weeks. Beyond this you may want to consider an ultrasound for seroma

What you are describing is quite commonly described after breast surgery.  The sensation of air trapped in the tissues is also commonly described. However, any significant increase in swelling/size would be of concern.

 Best wishes.
