I Love Piercings :: Risks associated with body piercing

Body piercing is an invasive procedure and is not without risks. When properly performed, these risks can be minimized, and most individuals who receive their piercing from a professional piercer, and who take care of their new piercing as recommended by their piercer, will enjoy a safe and healthy piercing experience.

Risks of note include:

Allergic reaction to ingredients of products used to clean the new piercing, or of ancillary products used in proximity to the piercing (e.g., soap, hydrogen peroxide, isopropyl alcohol, antibacterial products, antiseptic medicines, makeup, hairspray, swimming pool chlorine, etc.). This risk can be minimized by cleaning the piercing as recommended by a professional body piercer (different piercers will have differing recommendations), by not contaminating the fresh piercing with irritating products, and by not swimming in chlorinated water.
Allergic reaction to the metal in the piercing jewelry, particularly nickel. This risk can be minimized by using high quality jewelry manufactured from surgical stainless steel or similar inert metals.
Bacterial infection, particularly from staphylococcus aureus. However, this risk is greatly reduced when the piercing is performed by a professional body piercer using best practice piercing techniques, and when appropriate steps are taken during the aftercare period to avoid infection. Blunt force piercing, such as that associated with the use of ear piercing instruments, increases the chance of a bacterial infections. For that reason. among others, piercing guns should never be used to pierce any part of the body other than earlobes.
Parasitic and protozoan infections may occur by swimming in lakes, rivers, streams, and oceans during the healing period. The best way to reduce this risk is to avoid swimming in these locations.
Trauma to a fresh piercing, usually associated with unintended entanglement of the piercing jewelry with another object. This risk is always present, but can be reduced by using jewelry appropriate for the piercing, and covering or taping over jewelry during sports activities. Also, larger gauge piercings will tend to resist tearing better than smaller gauge piercings.
Viral infection, particularly from hepatitis B, hepatitis C and HIV. However, it is important to note that although hepatitis has been transmitted through the practices of ear piercing, body piercing, and tattooing, there has not yet been a case of HIV transmission associated with these procedures (see CDC Fact Sheet: HIV and Its Transmission). As with bacterial infections, the risk of viral infection is minimized when proper piercing techniques are used, particularly by the use of autoclaved disposable piercing needles and the autoclaving of jewelry prior to installation.
