Choosing an implant size is dependent on many factors. The first question is how much of an augmentation do you want? Plastic Surgeons have either computer simulations or breast sizing systems to help you imagine the size that you want to be. Once that is determined, an exam of your skin, your chest, and your breasts is done to determine if the size that you are interested in is appropriate for your body type. That is the most common way board certified plastic surgeons use to pick the "ideal" size for you. Breasts can change with weight gain or pregnancy. If you were to gain 20 pounds your breast size would change as well.Seek out a consultation with a board certified plastic surgeon- they will help you answer your questions.
Thank you for your question. Selecting your breast implant size is complicated. It is a combination of what you desire as well as what size your body can safely hold. An implant that is too large for your body dimensions can lead to problems down the line such as sagging, rib distortion, implant malposition, and stretching of the skin. It is best to find a board certified plastic surgeon who specializes in breast augmentation. During your consultation the surgeon will take measurements and guide you to the sizes that will fit your body.
