Medical professionals strongly advise against getting a tattoo during pregnancy due to a lack of safety data. Tattooing involves repeatedly puncturing the skin to deposit permanent pigment into the dermis layer. Primary concerns revolve around the risk of introducing infection and the unknown effects of chemical exposure on the developing fetus. Since no formal studies confirm the safety of tattooing for an expectant mother or her baby, caution is the standard recommendation.
Infection Risks to Mother and Fetus
The tattooing process involves breaking the skin barrier, which creates an entry point for various microbes and raises the risk of infection. Serious concern involves bloodborne pathogens transmitted through unsterile needles or contaminated equipment, such as Hepatitis B, Hepatitis C, and Human Immunodeficiency Virus (HIV). Localized skin infections like cellulitis or MRSA are also a possibility.
If the pregnant individual contracts one of these systemic infections, there is a risk of transmission to the fetus or newborn. A mother with Hepatitis B, for instance, can pass the infection to her baby at the time of birth, potentially leading to a lifelong infection. Furthermore, the immune system is slightly suppressed during pregnancy, which complicates the body’s ability to fight off a new infection and may delay the healing process of the tattoo site.
Chemical Safety and Unknown Fetal Exposure
The chemical composition of tattoo inks introduces a separate set of concerns. Tattoo inks consist of pigments and carrier solutions, which can include heavy metals like mercury, lead, and arsenic. These compounds are injected directly into the skin’s dermis layer, a tissue rich in blood vessels.
Although most of the ink remains trapped in the skin, trace amounts can enter the bloodstream and circulate through the body. There is insufficient evidence to determine the exact effects of these chemicals on a developing fetus, especially during the first trimester when organs are forming. No regulatory body, including the U.S. Food and Drug Administration, has approved any specific tattoo ink for injection into human skin. This absence of data means that the potential for long-term adverse effects, or teratogenicity, remains an unknown consideration.
Practical Concerns During Labor
A new tattoo on the lower back can create a specific complication during labor if the mother chooses to receive an epidural for pain relief. Anesthesiologists are trained to avoid inserting the epidural needle directly through pigmented skin. The theoretical risk is that the needle could core out ink particles and deposit the pigment deep into the spinal canal.
While documented cases of complications from this “tissue coring” are rare, the theoretical risk is enough for many practitioners to either refuse the procedure or attempt the insertion through an untattooed patch of skin. If a clear area cannot be found, the anesthesiologist may first nick the skin with a scalpel to avoid pushing ink into the deeper tissues.
The pain and stress of the multi-hour tattooing process itself can also be a physical burden, potentially causing a vasovagal response, such as fainting, especially with the lower blood pressure common in pregnancy. Furthermore, the significant weight gain and skin stretching that occur during pregnancy can permanently distort the appearance of the new tattoo.
