Is swallowing fingernails harmful

Answer 1

Fingernails will be partially broken down by the acids in your stomach. What's left will then move through your intestinal tract and become part of your stool.

On very extremely rare occasion, a sharp fingernail could become stuck in the appendix and could cause inflammation or appendicitis.

Answer 2

Fingernails are mostly made up of the protein α-keratin, the same stuff that hair, wool and rhinoceros horns are made of. I imagine that after some vigorous digestion, your body could break nails down into amino acids, but the amount of protein you could actually metabolize and use from eating your nails is very very small.

But, there are some very good reasons for NOT eating your nails or putting your fingers in your mouth. Nail biting can wear down tooth enamel and cause damage to teeth. Also, the area under the fingernails is one of the dirtiest places on your body.
