Can Vigorous Activity Lead to an Increased Risk of Saline Implant Rupture?

Activity can't rupture a breast implant. In fact, if you were left in the exam room alone with a sample breast implant you wouldn't be physically capable of rupturing it since they are made so incredibly resistant. If you puncture it with a needle, of course it will leak but otherwise you have nothing to really worry about it this regard.

Breast augmentation does not cause any physical or activity limitations. Implant corporations such as, Mentor, Allergan, Inamed, or Natrelle offer life-time warrantys on the implants. If in case of a malfunction, defect, or rupture, the corporation gives you a certain amount to cover most of the costs of the anesthesiologist and the surgery center fees. I definitely recommend consulting with a board certified plastic surgeon to discuss the best and safest possible options for you. However, unless the implant is actually punctured, there should not be any type of physical or excessive amount of pressure to cause the implant to rupture. Good luck and take care!

Vigorous activity is unlikely to rupture implants.  This is a common concern, though.  The most frequent cause of rupture is fold fatigue.  If you have an implant that is chronically folded on a corner or ripple, the material is weakened until rupture.  Capsular contracture contributes to this.  There is little need to modify your daily activities following breast augmentation.
