What causes belly button piercings to reject?
Because the ring is a foreign object that was shoved through your navel. There’s a higher risk eof rejecting if it gets infected, so just be careful not to irritate it. I heard that most belly rings get rejected after about 4 years, not at the beginning. When that starts to happen, the best thing to do is to just take it out and get it re-pierced. If you don’t do that, you’ll just be left with a hideous scar.
