What can hurt a liver like piercings or pirceings will any of this harm the body or the liver??

Certain diseases can harm the body and liver if perhaps you have a tattoo or piercing when toxics come from an infected needle:a needle that has not been sterilized properly.EG. A person has a tongue piercing or tattoo, the same needle is then used on a second person without sterilization between.Infection can then set in, which will cause serious health problems for the person concerned.

When you decide to have any piercings done be it, ears,nose,body etc.. or tattoos, make sure you go to a reputable salon.ASk other people who have visited there,enquire about the service... cleanliness,aftercare etc.
Should you choose to still have the piercing or tattoo done,try and sit in with someone having it done before you do, have a good look around,take note of the procedure... hygiene etc.. then make your final decision.

Liver failure is very serious and can be fatal. I had a wife die from that. If you have any concern or not sure, please have a check up. But Orphan is correct that plus dozens of other illnesses can all effect the liver
