Thank you for your question. This can really only be answered with a full of medical evaluation, but there are a few clues here that can help to guide you. Smoking, unfortunately increases the risk of any surgery let alone cosmetic surgery. Smoking inhibits blood vessels which bring the healing power of the tissues as well as the antibiotics that help minimize the risk of infection. Smoking can lead to tissue loss. It's always best to stop smoking before surgery. Second, you are very busy. While your question does not specify which surgery you are considering you must give yourself appropriate time to heal. I see patients make the mistake of not giving themselves the time that they need to recover safely. If you do embark upon elective surgery it's always good to have a support system in place and have more time than you need to recover. Better to have extra time but not need it than the other way around. Lastly, by your height and weight numbers you are slightly above your ideal weight. It is always good to be at a comfortable weight before surgery. This does not always mean rail thin, This means a weight that you can achieve in healthy way long term, a realistic weight. Even if you're not quite where you wish to be yet, It would be worthwhile to have a consultation. Your surgeon can point out ways to be of help for the safest surgery possible . Best wishes.
