Thank you for your question. Your concerns about your health are understandable. The primary factors a qualified, experienced plastic surgeon will likely consider include the cause of your pitted edema, the reason for your back pain and whether your blood pressure is under control with medication. Because liposuction is a surgical procedure, it is important to weigh all these factors very carefully before moving forward with your procedure. However, an experienced surgeon with all the facts and a full medical history will be able to make a safe decision concerning your body contouring goals. Your surgeon may also want to consult with your primary doctor to ensure there are no other issues to take into consideration. If you do decide to move forward with liposuction, I wish you all the best for a safe and successful surgery! - Morris Ritz, MB, BCh, FRACS
