Breast implants can experience subtle or major changes in shape, firmness and position over time. While implants themselves are designed to be durable, these changes are caused by the surrounding breast tissue, skin and chest muscles continuing to age over time. These can be further caused by weight fluctuations, pregnancy and hormonal changes.
These changes do not always mean there is a problem with the implants, but they can affect how the breasts look and feel over time. Understanding the causes of these changes can help a patient understand when they may want to consult their cosmetic surgeon for revision surgery.
As skin loses elasticity, breast tissue may begin to sag, and implants can appear lower on the chest, thus making them appear more noticeable or less supported than before. This loss of elasticity is because collagen and elastin, two substances responsible for skin flexibility, gradually decrease in amount with age.
Gravity also affects the breasts over time. Even when implants remain intact, the surrounding tissue and skin may stretch after many years. Larger implants can sometimes place additional weight on the breast tissue, which may contribute to sagging in some patients.
Weight loss may reduce breast volume, which can make implants appear more prominent or increase visible rippling in some cases. Weight gain can also affect breast appearance by stretching the skin and increasing breast size. If the skin stretches significantly, the breasts may not fully return to their previous shape after weight loss.
Rapid or repeated weight changes can have a greater effect on breast skin and tissue support over time. This may alter breast symmetry, shape and how the implants sit within the breast pocket.
Pregnancy causes the breasts to enlarge as milk glands and breast tissue develop. This stretches the skin and surrounding tissue, which can change how implants sit within the breasts.
After pregnancy and breastfeeding, breast volume often decreases again. Some women notice sagging, reduced upper breast fullness or changes in implant position following these changes.
Hormonal shifts during menopause can also affect breast tissue. Lower oestrogen levels may reduce skin firmness and breast density, leading to thinner tissue and less natural support around the implants.
Breast implant revision surgery is performed to address changes in implant appearance, implant-related concerns or changes in personal preference over time. Some patients choose revision surgery because their breasts no longer look or feel the way they did after their original procedure.
Revision surgery can involve replacing implants, removing implants or adjusting the implant pocket to improve breast shape and position. In some cases, a breast lift may also be recommended if there is significant sagging or stretched skin.
Patients may also consider revision surgery if complications develop. These can include capsular contracture, implant rupture, implant displacement or visible rippling. Revision procedures aim to restore comfort, improve symmetry and achieve a more balanced appearance.

Breast revision surgery should be carefully planned around the patient’s anatomy, implant condition and long-term goals. Every patient experiences breast changes differently over time, which is why a personalised consultation is an important part of the revision process.
During consultation, a plastic surgeon will assess factors such as implant position, skin quality, breast tissue thickness and overall breast shape. This helps determine whether implant replacement, implant removal, pocket adjustment or a breast lift may be the most suitable approach.
At Astrid Plastic Surgery, treatment is led by Consultant Plastic Surgeon Dr Jonah Kua, who takes a thorough and meticulous approach to surgical planning. Rather than relying on a one-size-fits-all method, each procedure is carefully tailored to the individual’s concerns, anatomy and desired outcome.
This personalised approach helps patients achieve results that look balanced, natural and proportionate.
