Could breast pumping have affected my silicone breast implants? Is this something I should be concerned about?

It is totally ok to pump for breastmilk after having breast augmentation. The manipulation of the breast from the pump is at the nipple and breast glandular level. Your implants are behind your chest muscles, away from the pump. It is highly unlikely that the pump could have caused a significant trauma to your implants one year out and the changes in your breast that you are noting are likely due to the changes in your breasts from pregnancy and the engoregement of the breast glands with milk. See your surgeon if you are concerned for an in-person exam.

Thanks for your question. Breastfeeding or pumping is extremely unlikely to have affected your implants in any way. Of course, the breast gland tissue itself will change w/ the hormone changes, but hopefully, those changes will not cause much in the way of long term problems. You can likely follow up w/ your surgeon once you are done nursing. Best wishes.

I think that pregnancy likely impacted your shape more than netting else. If you feel an implant isn't feeling full or normal, then an exam in person with your surgeon sounds reasonable.
