I'm a type 1 diabetic with average glucose control and I got my ear pierced about 2 years ago and I never had a problem. The key thing is to follow the cleaning instructions, as others have stated. Go someplace sterile...don't like do it wham-bam in a neighborhood garage. I got mine done at a reputable piercing/tattoo studio...double the price, but double the cleanliness. (That's good to follow for ANYBODY getting their ear pierced..not just diabetics).My sister is type 2, recently diagnosed and is thinking about having her ears pierced. She knows small sores and cuts can be a big deal for a diabetic so wants to know whether or not ear piercing is advised for diabetics.
