What is the real risk of weight loss after Breast fat Transfer? I am under the impression that fat cells shrink when losing weight they don’t just evaporate though it seems they do. If a month goes by after a fat transfer and cells have a blood supply, wouldn’t they just shrink with weight loss and then with weight gain become larger? Or can weight loss after the fat grafting cause some irreversible fat cell necrosis? Asking because I’m outdoorsy and weight fluctuates a lot with the seasons.
