Thank you for your question. I don’t believe there is a contraindication to drinking green tea after a CoolSculpting treatment. CoolSculpting works by freezing and crystallizing fat cells so they can be eliminated through the body’s lymphatic system in the weeks following treatment. Green tea would not impact that process in any way. I would ask your provider the reason behind the instruction to determine whether there is a particular circumstance I am not aware of, but I have never given this direction to my patients.
I do not have my patients avoid green tea after a CoolSculpting treatment and I do not believe the green tea would have any effect on the CoolSculpting results. I do generally recommend following the instructions of the doctor who treated you though.
