Can a general practice doctor perform liposuction?

Legally a general practitioner can perform liposuction but does not have specific training in surgery or plastic surgery.  However liposuction should be performed by experienced board-certified plastic surgeons who have taken years to develop the skills necessary to provide you with a proper technique and good results.  I strongly urged her to seek liposuction with an experienced board-certified plastic surgeon.

In the US, a license to practice medicine allows a doctor to LEGALLY perform any treatment they like (brain surgery, leg amputation, allergy shots, C-section, or manage blood pressure).  
The question you should be asking yourself is, would you ask your general doctor to perform a hip replacement for you, even though they are legally allowed?Your health and safety matter.  Be sure to discuss your goals and concerns with your board certified plastic surgeon and consider the pros and the cons. Be certain your surgeon is properly certified.  I've attached a link where you can start your search. 
I hope the answer is obvious.  Just because it's cosmetic, it doesn't mean it's not real surgery.If you can't afford a properly trained safe surgeon, save the money you have (and your health), and avoid surgery altogether.

Hello dear!Thanks for the question. Happy you ask before doing it with a general practice.The only doctor that it's allow to performance a plastic surgery is a BOARD CERTIFIED PLASTIC SURGEON. Always check on the official page of the association of plastic surgeon of any country you choose to have the surgery. It can be very dangerous to have surgery with a non specialist in the area.Hope this could help and good luck :)
