In 2008 I had breast reduction but was left with one side untouched. I have since lost over 100 pounds and it looks awful. I don't understand why that was left over and I need to know how much this will cost to repair.
First, congratulations on your weight loss success. Second, we can imaging how challenging it is to have achieved a healthy weight, but be left with unattractive breast appearance and asymmetry. Actually, major weight loss (MWL) often results in excess loose skin and tissues in various parts of the body. Breast lift or mastopexy is frequently needed after MWL, possibly with the addition of breast implants. Your situation sounds different, since you had prior one-sided reduction surgery. You should seek the advice of an experienced, board-certified plastic surgeon, have an in-person consultation, and discuss your options. You should be able to achieve an attractive, proportional and more symmetric breast appearance. Best Wishes.
You are describing a unilateral reduction, presumably done for improving symmetry and for eliminating the excessive pull on your larger side. Now that you've lost weight, you will need to see a surgeon for an evaluation for what options you have for improving your look. Your goals and expectations will be heard and appreciated, your anatomy examined, and your options provided. This is not an insurance covered procedure so expect to pay cosmetic rates for everything and costs will vary by what choices you make. But improvements can be achieved... unfortunately it will require mores surgery.
