I do a LOT of tummy tucks in my practice and while I suggest to patients that they monitor their salt intake postoperatively, I don't see any reason to avoid coffee.The concern must be about the caffeine content of coffee causing blood vessels to constrict and perhaps delaying wound healing. At least, that is what I would guess. As far as I know, there is no evidence that a cup of coffee is going to cause such a problem.Also, as far as sodium, it is clear that a very high dose of salt (e.g. Chinese food) will probably make you swell and become uncomfortable. Swelling after this type of meal seems to go on for a couple of days.Basically, in my practice, most dietary habits IN MODERATION are probably fine.
