Can I work out/do cardio a day after kybella?

I would recommend waiting at least a good 24 hours before vigorous exercise after you have Kybella injected.  I don't think that exercise would necessarily hurt your end results, but the increase heart rate and blood flow to your head might cause you to have more swelling than you would otherwise.  Some degree of swelling is normal for the first several days and will dissipate over the first week.  Better just to relax the day of your treatment and apply some cool packs as necessary to the area to help minimize the initial swelling.  Best of luck!

I give my patients a detailed instruction form after the Kybella injections. I ask them to do not exercise for 24 hours. After that time they can resume normal physical activity.
