What is wrong with my butt and can it be fixed? (Photos)

Thank you for sharing your concern with us. I recommend you to loose weight before considerate get these procedures done. You must be a healthy person, within an appropriate BMI of below 35, for safety reasons, to be a good candidate for the procedures you want at the same time, your labs and cardiovascular preoperative evaluation must be optimal.

Hello, thank you for your question. It is hard to tell without a proper physical examination. It is best to be within 10 pounds of your weight goal for three months prior to the BBL. I recommend you to schedule a consultation with a board certified plastic surgeon.

Dear sunnysan75,
it is hard to tell for sure without an examination. If you are considering a surgery, I would suggest you to consult a board-certified plastic surgeon. Only after a thorough examination you will get more information and recommendations.

A healthy BMI is between 15 - 24, the maximum recommended being around 30. If you are above 30, then you are encouraged to lose weight before undergoing surgery. The higher the BMI the higher the chance of complications. A Skype or FaceTime consultation with a board certified plastic surgeon will help you get an accurate recommendation for your procedure and for pricing.

You right gluteus has the appearance of having had radiation therapy.
This is often what the skin discoloration looks like and this treatment can also give fat necrosis.
Something is not normal and we would need your full medical history and examination and to get more information before giving you recommendations.
Based on the appearance and if something is physiologically different with the tissues I don’t think it’s going to be straightforward to correct this.
If this is due to previous radiation therapy then it will not be amenable to procedures like fat transfer.
I suggest talking to your primary care doctor and having a few in person consultations with board-certified plastic surgeons in your area.
Best, 
Mats Hagstrom MD
