Gummy Bear Implants Heavier Than Silicone Implants?

The density of the gummy bear implants and the less cohesive silicone implants is very close.  Unless you changed volume, there should be very little difference in weight. My guess is that your symptoms are not related to the type of implant. 

That said, if you are that uncomfortable four months after your operation, you should ask your surgeon.   We are not just here for the operation.   Our role in the process includes pre-operative counseling, the surgery, and all post operative care.  We expect and want problems to be addressed.

You need to tell your surgeon and have him/ her examine you.  If you are uncomfortable with your surgeon, find someone new.

Gummy bear silicone implants weigh about the same as regular silcone implants.  The larger an implant is, the more it will weigh and stretch the skin.  Just like large, heavy breasts, over time very large implants can cause breast discomfort or sagging.
