Human: My friend has a lot of tattoos, but I'm not sure how I feel about them. What are the health risks of getting a tattoo? Assistant: 
The health risks associated with getting a tattoo include risk of infection, allergic reaction, skin discoloration or scarring, permanent pigmentation changes, and even scarring if done improperly. Tattooing can also cause an increase in your body’s temperature, which can lead to heat exhaustion or stroke. It may also be painful and uncomfortable. In some cases, it can be dangerous for people who have certain medical conditions such as diabetes, heart disease, high blood pressure, or weakened immune systems.
