My breasts are shrinking. why?

How did you measure?: It is unlikely that your breasts are shrinking at your age. What makes you think that breasts have decreased in size? Without objective measurement to support your impression, it is unlikely that your breasts shrank, unless you lost a lot of weight due to a serious illness. If this impression is validated by objective measures, it would be prudent to see your doctor.

Breast: If you find your breast shrinking, you've likely either lost weight or your estrogen levels are falling, perhaps from going off the pill or impending menopause. If you're seeing shrinkage and none of those apply (especially if you also have hair loss, acne, and facial hair), consider being tested for polycystic ovary syndrome (PCOS),and see your doctor .
