Hola My Wish Body!In just about every plastic surgeons office there is a standard guideline of what you can and cannot take prior to surgery starting 30 days out from the procedure date.If you have been evaluated by your family doctor, physician or surgeon for any conditions that can affect your surgery then it is best to stay away from coffee/caffeine.With that said in most cases a cup of coffee won’t cause any issues one week prior to surgery in healthy patients.Diego Franco, MDColombian Board Certified Plastic Surgeon
