Can Eating Disorders Affect Breast Development?

Your breasts are affected by ptosis although it is difficult to determine the grade just by these photos alone. Dramatic weight fluctuations can contribute to sagging, and this may be what happened to you. 

Your photos show breast ptosis with the nipple below the crease under the breast. There is no way to know if your shape is due to weight gain and loss, it just is what it is. You are certainly not the only woman of your age who looks like this. The good news is that this can be fixed by a procedure called mastopexy or breast lift surgery.

There are two types of ptosis. True ptosis, as Dr. Rand indicated, occurs when the nipple falls below the horizontal level of your breast crease. Pseudo ptosis is when the breast gland (not the nipple) falls below the horizontal level of the breast crease. It is difficult to tell if you have a Grade 2 or 3 ptosis but it is true ptosis. Your weight gain and loss have contributed to the appearance of ptosis by the significant degree of volume loss which creates the "empty sack" look.
