Thank you for your question about how long you should wait after running a marathon before undergoing a lower and upper body lift. Running a marathon is a tremendous physical feat that places a lot of demand on your cardiovascular, muscular, and immune systems. Because of this, it is important to allow your body sufficient time to fully recover before having major elective surgery like a body lift. In general, I recommend waiting at least 2 to 4 weeks after completing a marathon before undergoing a lower and upper body lift. This gives your body time to recover from the physical stress and any muscle breakdown or dehydration that occurred during the race. Ideally, your energy levels, nutritional status, and lab values (such as iron and protein levels) should be restored to normal prior to surgery. If you experienced any injury, illness, or immune suppression from marathon training or racing, it may be wise to wait even longer—up to 6 to 8 weeks—to ensure you are in optimal health before undergoing a major procedure. Body lifts, particularly when combining upper and lower body lift procedures, are significant surgeries that require your body to be in top condition to heal well and reduce the risk of complications. Before moving forward with surgery, I recommend scheduling a consultation with a board-certified plastic surgeon who specializes in post-weight loss body contouring. Be open about your recent marathon and ask if any preoperative labs (such as hemoglobin, albumin, or CRP) are needed to confirm you're ready. If you have any underlying fatigue, muscle soreness, or signs of inflammation, it may be best to wait a bit longer before proceeding. If you have further questions about body lifts, including extended body lift, circumferential body lift, upper body lift, or lower body lift, I encourage you to consult with an experienced plastic surgeon who has performed at least 100 of these procedures and has before and after photos to show their work.
