How to Identify Gigantomastia?

Although breasts are comprised partly of fat, even drastic weight loss won't result in significant shrinkage in that area (and even then, the breasts will still be saggy). Many doctors ignore a crucial dilemma: When your breasts are so large, exercise is a miserable, if not impossible, option. Being overweight doesn't exclude you from having breast reduction surgery. In fact, it will motivate you to lose weight by improving your body image and freeing you to exercise with minimal bouncing and flopping.

Breast reduction surgery removes excess breast tissue and reshapes the contour of the breasts so that they are smaller and perkier. I commonly use a minimal incision technique (Le Jour), eliminating the need for large scars while providing a pleasing breast contour and shape that is proportionate to the patient's body.

During a consultation, the doctor should show you images reflecting the results of the procedure you’re considering, and seeing the photos can give you a sense of a surgeon’s aesthetics. I also do computer imaging, which allows us to photograph you and then immediately manipulate your features onscreen, so that you have an idea of a procedure’s “after effect.” Although you won’t come out looking exactly as you do on screen, your resulting image helps with decision making.

At 300 lbs I would suggest losing weight first and then having the breast reduction.  You may find that the breasts will shrink as well.  If it is too difficult for you to lose weight, then a breast reduction may help to ease the discomfort of the larger breasts and put you on track to get in better shape.
