Are navel piercings only for people with flat stomachs?
Answer Navel piercings work best for people with a thin fold of skin in the pierced area. Weight means less blood circulation in the area, so slower healing. Jewelry that fits with abut 2mm of extra space is best. If your piercing is getting sweaty and is not cleaned regularly you might have further problems. http://piercing.org/faq/aftercare.html has more information.
