Why Did my Breasts Shrink a Whole Cup Size?

How the breasts respond to fluctuations in weight is unpredictable. Persistent breast hypoplasia after regaining weight that was previously lost usually always requires surgical correction. Unfortunately, this type of weight fluctuation often leads to stretch marks and breast sag as well. For this reason, breast augmentation and breast lift surgery are probably both indicated to correct this problem in most cases.

Without difinitive hormonal diagnosis there could be many reasons for breast atrophy. Increasing volume and size could be accomplished with breast augmentation. You may want to consider consulting a board certified plastic surgeon to discuss your options.

It is very common for a woman's breast size to change throughout her lift. Many factors can influence this including: weight gain or loss, pregnancy, breast feeding, menopause (not likely in your case), and increasing age.

Breast augmentation is the best way to restore volume loss and restore a fuller breast appearance. Please discuss your options with a board-certified plastic surgeon. Best of luck!!

   Breasts usually atrophy over time, but weight gain and loss cycling may hasten atrophy.  In the absence of pregnancy or breast feeding, these would be two factors.  Getting back up to the old size cannot be reliably accomplished without breast augmentation or weight gain.

at your age are like related to weight or hormone fluctuations.  If you are desiring a fuller breast, you should see a local plastic surgeon (preferably board certified if you have no idea who you are seeing) about what options you have.  Good luck!

Breast size does change with time, and can vary in response to hormonal changes and weight change. The changes do not always reverse themselves with restoration of normal weight or hormonal balance.

To get back to size, consider breast enlargement surgery.

Breasts certainly change with time. Often the breast becomes fattier with age and less glandular.  Why yours changed a cup size is unclear.
