Does caffeine constrict blood supply to the fat transferred to the breasts?

Hello, high amounts of caffeine is indeed a vasoconstrictor or constricts blood vessels which may inhibit the healing process of fat transfer and may inhibit the amount of blood circulation that helps keep the fat harvested alive. If you're thinking of having one cup of coffee, tea, or coke, that's fine. I do not recommended more than that post surgery.

The only opinion that matters is that of your PS; ask him or her.  I know of no studies indicating that caffeine has ill effects on fat transfers.

Interesting question! Caffeine intake will not hurt circulation or take of your fat. In fact, many of my patients complain of headache after surgery and I encourage them to resume usual caffeine intake so they don't feel as poorly!Best of luck!

Coffee is usually not strong enough to make much difference on small vessels' blood flow, so drink up what you want.

Caffeine does not cause significant vasoconstriction such that it would impact your result following fat grafting.  I think the headache that you might have with caffeine withdrawal would be worse.  Drink your coffee and rest easy!

You can have your cup of coffee. It will not impact your grafted fat cells. It might make your own breast tissue sensitive especially if you have breast cysts.
