Empty breasts after weight loss: what can be done?
When your breasts look empty after losing a lot of weight they seem to sag, but often what is missing is volume, not a lift. The breast measurements decide: if the breast has kept its position and only emptied, a breast augmentation is enough; if it has also dropped and there is excess skin, you need a mastopexy, alone or with an implant.
With Dr. Lucrecia Villanueva, plastic surgeon on our breast surgery team.
Restore volume with a breast augmentation
Why do breasts look empty after weight loss?
When you lose a lot of weight, the breasts lose part of their volume and the skin that covered them becomes looser. The result is an empty breast that looks droopy at first glance, even though it often is not as droopy as it seems.
That is why the solution is not always the obvious one. A breast augmentation may be enough, or you may need a mastopexy, and what decides it is not the first impression but the breast measurements.
Empty or sagging breasts? The measurements decide
Dr. Lucrecia Villanueva explains it with a patient of about 30 who had lost a lot of weight: "At first glance she seemed to need a mastopexy, because her breasts looked very droopy. However, when we took the breast measurements, we found that what she was really missing was volume."
At the consultation we measure the breasts and the chest to see whether the breast has kept its position and only emptied, or whether it has also dropped and there is excess skin. We explain this in more detail in why precise measurement matters in breast surgery.
What was done in this case?
Only a breast augmentation, with no lift. "We performed only a breast augmentation, through the inframammary fold, shaping the breasts to what she was looking for," says the doctor.
With the inframammary approach, the 4 to 5 cm incision sits in the fold under the breast. The implant is chosen with a dimensional method, based on those same measurements; we explain how in choosing the right breast implant size. The procedure is done under general anesthesia and takes 60 to 90 minutes.
When is a mastopexy needed after weight loss?
When the breast has not only emptied but has also dropped and there is excess skin. A mastopexy removes the excess skin and repositions the breast; if volume is also missing, it is combined with an implant in the same procedure.
This often happens after pregnancy, and we explain it with another of the doctor's cases in sagging, empty breasts after pregnancy.
Should you wait until your weight is stable?
Yes. If you are still going to lose or gain a lot of weight in the short term, your breasts will change again, which is why we do not operate until your weight is stable. Once the augmentation is done, moderate weight changes do not usually affect the result.
What is recovery like?
You can return to everyday life and office work within 7 to 10 days, gentle exercise at 4 weeks and high-impact sports at 6 weeks. The result settles in between 3 and 6 months, once the tissue has adapted to the implant.
Frequently asked questions about empty breasts after weight loss
How much does breast augmentation cost?
From €6,250 (VAT not included). The final price depends on the implant, the technique and the tests; we explain it in the cost of breast augmentation. The consultation costs €80 and is deducted if you go ahead with surgery.
Do empty breasts always need an implant?
If what is missing is volume, yes: a mastopexy on its own repositions the breast but does not fill it. In selected cases, the volume can come from the patient's own fat instead of an implant.
Can the first visit be a video call?
Yes. If you cannot travel, the first visit can be a video call with the surgeon who would operate on you. It costs €50.
