HI @mrtwitter, anything that creates a break in the skin are susceptible for infection and might cause other complications. Body piercing pierces through the skin on the different parts of the body and if there is no safety measures done like proper hygiene and use of needles are done indiscriminately this could be dangerous.

Body piercing are quite popular nowadays, some do this for fashion while others as a sign of expression, for individualism and others opt for this for the sake of art.

If you are planning to have your body pierced, these are some things to keep in mind:
1. All kinds of piercing including the ears can take up to six weeks for it to totally heal. Piercing the navel can take 3-4 weeks and depends if there is presence of infection or not.

2. Be sure that you go to a licensed and established shop that is run by professionals. This is important because improper using of tools and unsanitary practices can increase the risk of getting a disease like hepatitis or HIV.

3. Ask a reliable person on the risks and possible infection you will get. Sweat can sometimes cause infection so it would be best to discuss it with the person you are dealing with.

All body piercings can be relatively safe as long as the area being pierced is kept clean during healing, and also that the individual doing the piercing maintains all health and cleanliness standards required for the job.

There are parts of the body that, when pierced, may have a higher chance of infection, like any tongue, mouth, or nose piercings, because of the number of germs that pass through those areas. From my research I've found that tongue, lip, and cheek piercings can cause gum disease and tongue piercings can also cause your teeth to deteriorate.

Piercings can be dangerous in many different ways that no one even considers including heart disease. Also, if you have other health issues like diabetes or pregnancy, you should ensure that it is OK to get a piercing by consulting with your physician.

As long as all precautions have been met, make sure that you have all your shots up to date, including Hepatitis B shot, and if you are getting a piercing in your mouth, lip, cheek, or tongue, that your gums and teeth are very healthy. A visit to the dentist should be done. Make sure that if you feel extreme pain in the site of the piercing that you see a doctor right away. Infections that are left untended become very hazardous to your health.
