What should I check during the recovery process after liposuction?

I have a question for those considering liposuction. I am curious about what specific precautions should be taken during the recovery phase after surgery. I would appreciate it if you could share any effective methods to alleviate swelling and pain, or any behaviors to avoid. I am also wondering what kind of diet is helpful during the recovery period. I would like to make a better decision based on your advice and information.
