Optimal candidates for surgery should have reached a healthy stable weight preferably with a BMI < 30.With regards to your specific question, BMI is calculated based on height and weight. Thus the ideal BMI (i.e. weight) for anyone with a height of 5'3" will be the same (assuming the same sex). This weight would be less than 170 lbs.As always, discuss your concerns with a board certified plastic surgeon (ABPS).
Thank you for your question. The recommended BMI prior to an elective surgery is less than 30 for health and safety reasons. If your height is 5'3'' your weight should not be over 170lbs to reduce the rate of complications during surgery and optimize your results. Seek a board certified plastic surgeon who performs many of these procedures, has great reviews and photos, and is an expert in this field.
